Cleaning machinery

Imagine one single machine featuring all the technology to surface 80 lenses/hour, in just 72 sq.ft. This is the new Modulo Center ONE. The all-in-one surfacing center is a full-fledged production line without limitations: a milling station // a lathe turning station // one or two 4-spindle polishing units // a CO2 or excimer laser

Modulo Center ONE features highly advanced Modulo ONE process technology as well as robust and reliable components proven in hundreds of installations across the globe.

An inner ring forms the basis for the smart and swift automation featuring multiple handling systems. Substantial time savings are won through the machine’s tight integration and by running all processes simultaneously – even milling and lathe turning. The result: There is no faster way to surface a lens.

Its’ dedicated Control Center (MES) informs at a glance about the current status of the machine, production parameters, and efficiency.

With Modulo Center ONE the jobs are processed in a fully automated environment without any need for operator intervention. Simply put: Blank in, surfaced lens out.

Imagine...

The year is 2025. Imagine you put on a pair of VR glasses. Now you are immersed in a wonderful 3D world. You see nature in bloom, hummingbirds in flight – all in the most vibrant colors. From time to time you see different visual impressions. You decide independently which image is better. And after a short time you get the precise prescription lenses, exactly as you would with a subjective refraction on a phoropter.

will be able to carry it out themselves entirely independently.

Block-free manufacture can also completely turn production in the lab on its head, rendering many process steps obsolete. Such a changeover would certainly be desirable for many users, although there are currently still limitations. To find out more about changes and challenges of this technology, see the detailed article in this issue.

The lens order from this refraction is sent to a lab where there is no alloy, glue, blocker or deblocker. This is because the lenses are made by a block-free production process where many of the conventional production operations are now obsolete.

The lenses that come back from the lab are no normal lenses, nor are the spectacles you hold in your hand. At the touch of a button, what appear to be lenses for seeing things far away are transformed into reading glasses – without aberrations or limited fields of vision, as in progressive lenses.

All a dream, you may think? Well not quite. Admittedly, this vision is slightly utopian, combining three separate scenarios that are currently being developed and tinkered with individually. However, in reality, each of these technologies is either already available on the market or close to their market launch.

Our in-depth article and interview about light-field display technology concerns a radically new type of refraction. This innovation could significantly transform subjective refraction in the future, allowing users to fully immerse themselves in a completely new world. Also, further into the future, it is set to become autonomous, meaning that users

And what about ‘near addition’ at the touch of a button? We got to see it live in Belgium. The glasses actually work with the features described, and MAFO was even allowed to take a look at the production process. The smart glasses still have some limitations which need to be ironed out, but they also have great potential. This issue also features a profile of the start-up company.

Thus we can already expect a lot of process innovations and surprises in the New Year. Products which would have seemed unthinkable just a few years ago are now ready for market. The process of buying, measuring and manufacturing glasses is constantly and continually evolving.

The year is 2030. Naturally we haven’t woken up in a completely changed world. We have been observing developments far too closely for that.

But we now know whether block-free manufacturing has caused a revolution – or not. Perhaps we are all wearing smart glasses on our nose that have been fitted by an optician using a phoropter; or maybe we’ve had a VR-refraction at the shopping center and then bought a pair of conventional glasses from the optician next door. Anything is possible.

Five trends, five articles

MAFO articles you should have read in 2024

Many exciting and topics and processes in ophthalmic lens production and development have shaped the industry in 2024. This is also reflected in the articles MAFO published in 2024. Here are the top five technology articles you should have read in 2024. All MAFO issues can be found here: mafo-optics.com/magazine/

1. Digitalization and the internet of things

Issue 01/2024 The fusion of digitalization and the Internet of Things (IoT) is poised to usher in a new era for industrial producer across various industries, specifically within the ophthalmic industry with it´s one piece flow mass production. In order, to create the lab of the future through technology, it is imperative to understand these technological advancements and how labs need to adapt.

By Dr. Michael Kreis and Xavier Bultez

2. Adaptive smart glasses

Issue 02/2024 Presbyopia affects everyone at some point. To address that need Der ground-breaking progress has been made in recent years, particularly in the field of spectacle lenses with liquid crystal lenses. This article gives a brief insight into the developments of adaptive optics, the corresponding structure of liquid crystal lenses and the resulting benefits in practice. By Lena Petzold

3. Myopia management lenses

Issue 03/2024 The global surge in myopia prevalence has raised concerns among practitioners, driving the need to develop effective myopia management solutions. A lens with asymmetric myopic peripheral defocus (MPDL) has been specifically designed to address the problems related to progressing myopia which fully corrects the refractive error at the fovea while inducing a myopic defocus on the peripheral retina. Furthermore, this design is produced by means of freeform technology, eliminating the need for special semifinished products.

By Eva Chamorro and Jose Miguel Cleva

4. Automated cosmetic inspection

Issue 05/2024 To date, trained human experts have the sole responsibility to check each lens for surface irregularities. This purely manual process is strictly regulated by each lab’s in-house quality standards. It is both labor intensive and dependent on the inspectors’ perception. With the development of a smart system – that can automate the process with the help of artificial intelligence (AI) – this has changed. The system takes over a vital role in supporting the quality control: it inspects lenses and mimics the companies’ individual decision-making patterns to reflect a labs’ unique quality standard. By Dr. Marcel Mahner and Kim Kathrin Leidig

5. Lenses for visually impaired people

Issue 01/2024 Counterintuitively, the health care improvement that we have witnessed in recent decades and the resulting increase in life expectancy have raised the number of visually impaired people. This happens because most eye diseases that cause vision loss are age-related, so their prevalence increases as more people enter the older population group. By Gaetano Volpe and Pasqualle Fanelli

Spoiler for 2025: Blockless generating

Issue 01/2025 To be fair, this article is published in this issue and is therefore not part of the review of 2024. But it was for sure a huge trend topic in 2024 as blockless generating is still one of the most discussed topics in the lens manufacturing industry. This will certainly remain the case in 2025, as technology is constantly evolving. Read the article about “Opportunities and challenges of blockless lens surfacing technologies” on page 12. More articles on this topic will follow in 2025. ◆

Blockless lens surfacing technologies

Opportunities and challenges

In the ophthalmic industry, the process of lens surfacing has been largely dominated by alloy blocking, a technique that has stood as the industrial standard for decades. Approximately a decade ago, Satisloh introduced ART (Alloy Replacement Technology), providing the first viable, alloy-free and environmentally friendly blocking alternative, which has since been widely adopted and used in hundreds of lines around the world. Despite the advances that ART has made, the industry now faces a significant question: to what extent will the future of lens surfacing be blockless, and when will this transformation happen? By Dr. Michael Kreis

Before exploring a possible blockless future, it is important to understand why lens blocking is so important in lens processing. Both alloy and ART block-pieces play a crucial role in ensuring precise positioning, stability, and protection of the lens throughout the production process.

Why is a blockpiece needed?

Here’s a breakdown of why it is needed and what functions it serves: Ensure positional accuracy: Blocking ensures accurate positioning in all six degrees of freedom for the lens, including three rotational and

three linear movements. This precision is critical to accommodate various lens geometries, such as front side progressive, bifocal, and trifocal lenses, as well as lenses with features like tints, gradients, or polarization. Keep the lens in position during cutting: The block-piece stays as a reference during all cutting operations. Therefore, the blocking technique needs to provide mechanical strength and rigidity.

Support of the lens during surfacing: Especially in the fine cutting stage with a diamond turning tool the block provides mechanical stability, preventing the lens from flexing or deforming due to cutting forces. Choosing a block-piece that provides maximum support, reduces

the risk of deformation and increases the quality of the cut, resulting in high-quality finished lenses which maintain their intended curvature and thickness through each production stage. This support is particularly important for thin lenses or lenses made of softer materials like polycarbonate. Choosing the right surface coverage allows processing lenses with thin edges.

Transportation: Once blocked, lenses can be safely transported in a job-tray through various stages of production, including cribbing, milling, turning, polishing, and in some cases AR coating, without losing positional alignment while having protection because the lens is not touching the tray.

In a blockless process all these functionalities must be redesigned to produce lenses with the same quality and consistency.

A new approach to blockless surfacing

Blockless surfacing aims to streamline and simplify the process steps by reducing the need for separate machines for each stage. However, blockless technology also presents new challenges (Fig. 1).

Satisloh is actively working on a blockless surfacing solution utilizing their well established and proven technologies and processes. The goal is to create a reliable, blockless line that integrates processes from other Satisloh machines, holding, aligning, and positioning lenses without a traditional block.

The new generator is based on the well-known VFT-orbit-2i . Modifications like a pre-cribbing feature, lens positioning technologies derived from the ART Blocker-A and a specific vacuum lens reception are enabling it to function as a fully blockless generator.

Fig.2: Future blockless technology: generating, engraving & polishing. Picture: Satisloh

Meanwhile, polishing will be performed in a redesigned Multi-FLEX-2 machine including new features that process lenses of various types without a block-piece (Fig. 3).

Multitasking machines versus modular systems

One critical consideration for labs interested in blockless is the choice between multitasking machines and modular loop or line setups with separate machines. Lens production requires multiple stages, each with varying demands depending on lens material.

For instance, polycarbonate lenses are faster to process in the turning stage, but polishing can take much longer than other materials like CR39 or high-index lenses. The ophthalmic industry is unique, requiring a high capital investment while having high numbers of individual work pieces produced in a “one piece flow”.

Having lines running 24/7 with the highest possible utilization and output is key to competitiveness. Due to this very specific way of manufacturing, many decisions revolve around trade-offs in efficiency, flexibility, and downtime management.

Multitasking machines integrate multiple processes into one unit, which simplifies workflows but suffers from lower overall efficiency due to compounded downtime; if one module fails, the entire system halts. In contrast, modular loop or line systems decouple process steps by using separate machines for each task, such as multiple blockers, generators, and polishers. If one machine goes down, others in the loop can still operate, maintaining production flow.

Besides reducing the impact of individual machine failures, this approach allows for superior load balancing with different materials and improves overall system efficiency. Due to the generally higher output separate machines can also be competitive in terms of lens per hour per square foot and investment per lens per hour.

There are different opinions on which option is fundamentally better, and it depends on the requirements and needs. But from Satisloh's perspective the loop or line configuration remains the preferred option. Its modularity enables better line balancing, easier maintenance, and a reduced risk of system-wide stoppages.

This preference is reinforced by evidence from other production industries, where separate, multi-functional machines have demonstrated greater efficiency than all-in-one solutions.

Opportunities and benefits of blockless technology

The shift to blockless technology offers numerous potential advantages, especially in terms of production simplicity and efficiency:

▶ Fewer production steps: Eliminating two stages, blocking and deblocking, shortens processing time.

▶ Reduced set-up times: Simplifying the process reduces set-up times, allowing faster transitions from one stage to another.

▶ Lowered material costs: Eliminating block pieces and blocking consumables reduces operational expenses.

Challenges of initial approaches to blockless surfacing

From Satisloh´s perspective the initial approaches to blockless technology that have been recently introduced to the market have shown technical and operational limitations that need to be addressed before the technology can become a viable industry standard.

On the one hand this is a reduced working range: The front and back lens curve are significantly limited, as well as the diameter range, the lens material choices and non-rotationally symmetric surfaces like front side progressives cannot be processed.

Another challenge is reduced throughput: Due to additional machine functionalities required for blockless processing, throughput of current

Fig.3: Now and future chain process. Picture: Satisloh

approaches is lower than traditional blocked processes. This limitation is critical for high-volume labs where maximizing production capacity is a top priority. And finally line balancing and machine downtime is a challenge: With traditional blocking, multiple machines handle specific stages of production. If one machine experiences downtime, the rest of the line can often continue. This often does not apply to multitasking machines that handle multiple steps, and where any machine downtime impacts the entire process. This limitation underscores the importance of line balance and redundancy in high-volume production settings.

Overcoming blockless technology limitations

The new approach aims at overcoming these limitations by introducing several solutions:

Patented pin vacuum reception : Satisloh’s pin vacuum reception functions similarly to a pin-point impression mat, combined with a protective tech membrane and vacuum-based grip, providing the support needed to hold the full lens diameter securely without a traditional block. Tests have shown that this technology holds the lens as firmly as the ART blocking process.

Integrated smart cribbing technology: Integrated into the blockless generator, smart pre-cribbing technology eliminates knife-edge lenses, preventing damage to the pin vacuum reception, while processing lenses of a wide range of diameters and almost unlimited prescription range.

Throughput: Based on Satisloh´s proven technology, and processes we expect the same quality results with only a slightly lower throughput reaching 80 lenses per hour.

Line balance : By ensuring compatibility with current line or loop configurations, Satisloh’s blockless machines will work alongside traditional systems, offering flexibility and reducing potential disruptions as labs transition to blockless surfacing.

Initial results

Satisloh’s initial tests with the company’s blockless system have shown promising results. For example, a CR39 progressive lens with a base curve of 2.50, back curves of -2.00, and -4.00 in the two major meridians, and an addition of 2.00 was processed on the blockless system. The quality and cosmetic results were comparable to lenses processed with ART blocking technology in both cosmetic and optical quality. Furthermore, preliminary testing across various materials, prescriptions, and diameters has shown that almost the entire range of materials and geometries can be processed with only small limitations. ◆

Addition at the touch of a button

A visit at Morrow in Belgium

A Belgian start-up has a product that many people have long dreamed of: glasses with combined far and near correction, but with the comfort of a unifocal lens. The addition is done electronically and activated via touch of a button. The 3D-printed smart glasses are already on sale in some regions. MAFO visited the company to see the production process and test the smart glasses. By Hanna Diewald

We are in an industrial area near the Belgian city Ghent, looking for the start-up Morrow. The young company's offices and production facilities are supposedly hidden in a large brick building. A discreet nameplate at the entrance to the building is the only indication that we are in the right place. We take the elevator to the fourth floor, where we will meet later the CEO Frederiek Ysebaert and his team.

Addition with one click

The glasses we are seeing here today are something very special. They are designed to make the dream of many people come true: addition at the touch of a button.

The glasses are suitable for presbyopes. At the same time, however, they are designed to do without the typical limitations of progressive lenses. For example, the aim is to completely eliminate distracting aberrations.

Instead, users should benefit from a large, wide distance range and a smaller near range, the addition of which is only “switched on” when required. However, the current model is more or less a hybrid of smart glasses and progressive lenses ‒ but more on that later.

“After years of research, I think we launched one of the most innovative technologies in the market for presbyopic people,” says Davide Airey, Chief Sales Director, proudly describing the glasses. “Progressive lenses have been one of the most important innovations of the eyewear market. But at the same time, they are a compromise between far and near distance.”

Smart and 3D-printed

Ahead of us lies a model box with different versions of the smart glasses, which are also available for opticians to show customers. The frame is currently still 3D-printed, but will be available in other materials in the future.

The current model is available in different colors and shapes. Visually, it is similar to other 3D-printed frames, although the temple must of course be slightly wider, as this is where the technology and the button are housed. The glasses weigh around 40 grams and the battery should last around two days before the glasses need to be recharged.

The spectacle lenses look in the area for distance viewing like any other transparent lens. However, one can see the potential reading area in the lens, which is similar in size to that of a bifocal lens. This is because at the point where the addition is generated by clicking, you can see a film shining through, with fine rings and dots visible. However, in the wearer´s face this zone of the glasses is hardly recognizable at first glance.

The liquid crystal lens sandwich

Now we want to try the glasses. A customer who orders the glasses will of course receive them in the appropriate diopters. For us, the test is a small compromise, as the distance is not corrected. Nevertheless, it is clear that the addition can actually be produced at the touch of a button and makes reading easier. The glasses function as they should ‒ but how exactly does it work?

The Chief Sales Director explains that the glasses are constructed like a sandwich. In the middle of the “sandwich” are liquid crystal lenses that change their orientation when tension is applied so that the light is refracted more or less strongly. Additionally, a normal spectacle lens sits both in front of and behind the foil with liquid crystal lenses.

Active and passive addition

However, there are currently still limitations. For example, the electronically generated addition is still limited to one diopter. Nevertheless, many people who require a higher addition are already wearing the glasses. To make this possible, the company works with a trick they call passive addition.

A progressive lens with slight addition is used for one part of the sandwich lens. The additional addition of the liquid crystal film adds up the power. However, the aberrations remain low, as it is usual with low additions in progressive lenses.

In the middle of the "sandwich" are liquid crystal lenses that change their orientation when tension is applied so that the light is refracted more or less strongly.

Preparing the films requires maximum concentration.

The middle layer of the “lens sandwich” is created from huge rolls of foil.

Pictures: Hanna Diewald

In future, it should also be possible to further increase the active addition. There are also plans to increase the size of the addition zone. At the moment, the size of the special area is similar to that of bifocal lenses. If the start-up succeeds in significantly enlarging this field, the glasses would also be extremely exciting for working at the computer and other screen-based activities and much more.

Now that the basic questions have been answered, Anshul Sharma, Head of Operations, shows us around the production facility.

Under yellow light

Many important steps in production take place under the strictest hygienic conditions in a cleanroom (ISO 6). This means we have to change clothes before entering the critical area. A smock has to be worn, shoe covers, a cap for the hair and of course a face mask ‒ absolute cleanliness is mandatory here.

We enter a yellow-lit room, which is once again protected by a slatted curtain. Highly concentrated employees are working on the first steps. “Here we have open layers. That's why it has to be 100% clean. You also see that we have light sensitive materials here, like adhesives, which are UV sensitive. That's why everything is done under the yellow light,” explains Sharma.

Here two plastic substrates are adhered together using a UV sensitive adhesive dispensed through an industrial inkjet printer. Then, prepunched substrates are filled with liquid crystal under vacuum using a

special machine. From the outside, the liquid crystals look like any other transparent liquid.

In the small production area, you can see very different machines put together to create a semi-automated pilot production line. Some manufacturer brands are well-known in the ophthalmic industry, others not at all. The Head of Operations, Anshul Sharma explains why this is the case: “Market existing tools are there for certain applications. But we need to adapt them to make them work for our processes. That's one of our biggest challenges when you come from producing like 20 samples in a month, and then taking it to like >400 samples a month. That's one big goal to increase the throughput further.” After quality control of the filled films, it's on to the next step.

Assembly area

In the next room, liquid crystal lens stack and ophthalmic lenses are assembled to generate ophthalmic industry compatible puck called e-blanks. The special machined fronts are received from their partner Tokai. Once a customer order is placed, the e-blank is sent back to the manufacturer Tokai. Only now is the progressive surface milled into the lens. This is why you can still see the block piece on the e-blanks at Morrow.

However, the special sandwich lens is not yet finished and also the production process in Belgium is not yet complete. The coating is still missing and, of course, the lens still needs to be edged. These steps will be carried

Finished e-blank.

Using a special process, the foil and two lens blanks are combined to form a so-called e-blank.

out again at Morrow in Belgium as soon as the e-blank with the right diopters and design comes back from Tokai.

As the special lens cannot be coated with conventional vacuum coaters, the start-up uses film lamination technology from the manufacturer Satisloh. With this technology, the anti-reflective coating and the hard coating are laminated onto the lens in the form of a special film. In the final step of lens production, the lens is edged using a MEI edger.

Lens and frame combined

The final step is to combine the 3D-printed frame with the special lens. This is no trivial matter, as electronics are built into both the frame temple and the groove. The Belgians therefore use a patented technology in which a conductive layer and a special coating are used to connect the two components.

The smart glasses are now ready. But how do the smart glasses reach customers?

The special glasses are sold exclusively by opticians and are currently only available in Belgium and France. But the company wants more. New markets are being closely observed and strategies developed. In five years, the glasses should be available on at least three continents: America, Asia and Europe.

So far, the start-up has hundreds of customers and not yet thousands, explains CEO Frederiek Ysebaert. Step by step, however, the aim is to go further and make the product even better.

Ambitious goals for the coming years

Ysebaert would like to expand the frame materials in order to make the models even more fashionable and chic. In addition, the active electronically generated addition should produce more than one diopter in the future.

And last but not least, the company is working on ways to extend the active part to the entire lens. However, this is also about sales strategy. The current retail price is already around 1,200 euros. As the liquid crystals are expensive, it is important to consider whether extending the active part is also worthwhile from a financial perspective. Work is also being done on a way to keep the frame separate from the lenses in the long term. This would mean that, thanks to the special electronic lens, every frame could become smart glasses with switchable addition. The potential is likely to be huge, because even if the glasses are not of interest to absolutely every presbyope, there are target groups that are likely to find the glasses particularly exciting. “The obvious target audiences are people that already have issues with progressive lenses ‒ the non-adapters ‒ and young presbyopes that want to postpone the day that they are actually progressive wearers. But also all people with active lifestyles will benefit more from the technology than others,” summarizes the CEO. With ambitious goals in mind, the company is looking to the future and we are curious to see when we will be able to buy the first glasses with addition at the touch of a button here at the optician around the corner. ◆

The company plans to pioneer lens coating technology and transform ophthalmic labs by merging precision, sustainability, and creative freedom. With its digital coating system, the company plans to deliver customization and efficiency while at the same time addressing current industry challenges such as inventory cost, production inefficiencies, and environmental impact.

As traditional lens coating processes are well proven for mass production but at the same time, are often based on rigid and resource-intensive techniques that limit design flexibility. From flō Optics’ perspective, the advent of direct digital coating technologies represents a quantum leap in optical manufacturing, offering many capabilities in lens surface modification. Furthermore, the procedure is easy: opticians capture desired colors or

patterns using the provided software and send it to the Rx lab with their order. The digital files are then transmitted to the printer, and finally, the coatings are applied directly and accurate onto the lenses.

Digital printing process

flō Optics’ additive manufacturing technology for spectacle lens coatings is a modular multistage production line in which functional optical inks are digitally printed directly onto the surface of any type of Rx and non-Rx lenses.

In this modular coating system, lenses are transferred between various stations for surface treatment, digital printing, drying and inspection.

The patent-pending process produces photochromic, tinting, and hard coat functional coatings, which are characterized by an engineered multilayer/multi-material optical stack structure.

Structured multilayer/multi-material coatings are produced by a series of non-contact ink deposition print heads, controlling the process at the level of a single drop. The level of material deposition control enabled by the coating process enhances the performance, repeatability, and quality of the functional coatings.

Photochromic coatings produced by the company’s proprietary multilayer/multi-material approach are a prominent example of how

the tinting ink can be discretely deposited on any pre-determined area of the lens (Fig.1), with digital printing accuracy and repeatability. Also, hard coatings can be applied with enhanced durability and without batch processing. Whether on traditional lens materials or on challenging substrates like polycarbonate, the system delivers consistent, high-quality finishes.

Coating application mechanism

The high quality is achieved by several steps. Firstly, by a digital printing interface that converts digital design specifications into precise coating instructions.

Next, a controlled droplet deposition ensures uniform coating distribution with minimal material wastage, and finally, the real-time calibration continuously monitors and adjusts coating parameters, with an inline inspection module using image processing and spectrometry.

Every produced lens is analyzed, and data is provided on product and process quality. The digital coating system introduces several critical technological advances:

Precision micropatterning: Enables coating application with micron-level accuracy, transcending traditional dip-coating or spray techniques.

Material substrate versatility: Capable of applying specialized coatings across diverse lens materials, including challenging substrates like polycarbonate and high-index polymers.

Material science and coating dynamics: The digital coating technology leverages advanced material science principles like inkjet materials formulation that ensure optimal coating performances across diverse lens substrates.

The micron-level-accuracy application enables the creation of ultra-thin, uniform protective layers. The customizable surface modification allows introduction of specific optical, protective, or aesthetic properties.

Additionally, the system supports the introduction of new types of materials that traditional processes are not able to handle, or that are too expensive if applied on all the lens surfaces. And finally, the digital workflow integration is a seamless software-driven process that transforms coating from a purely mechanical operation to a data-driven, programmable manufacturing step.

Why digital coating?

The demand for personalized, sustainable, and cost-effective eyewear is growing. The start-up provides a solution that addresses those needs while enhancing lab profitability and customer satisfaction. Traditional coating methods require maintaining large inventories of pre-coated lenses, many of which risk obsolescence. This system should enable labs to coat lenses on demand, reducing overhead costs and waste. Some examples of the economic advantages are: elimination of semi-finished inventory holding working capital costs, reduced material consumption, and greater production flexibility, which accommodates seasonal trends or custom orders.

Sustainability redefined

The digital coating process significantly reduces water and energy consumption while minimizing waste, aligning with the growing demand for green manufacturing. The company estimates a reduction in water consumption of around 80%.The chemical waste is reduced compared to a traditional process and the process leads to minimized transportationrelated carbon emissions due to on-demand production.

From flō Optics´ perspective, the digital coating technology marks a critical inflection point in optical manufacturing. It transforms lens production from a standardized industrial process to a flexible, datadriven, and environmentally conscious technological ecosystem. ◆

A radically new way of subjective refraction

Digital light fields for vision care

What does the future of subjective refraction look like? A Swiss start-up has an answer: refraction should be digital, offer almost unlimited display options, and also be independently manageable by the customer. Subjective refraction with the help of light field displays would therefore change the traditional way of doing the subjective refraction with a phoropter or trial frame set tremendously. Even a “refraction automate” in a shopping center is theoretically conceivable in the future. This article explains how the technology works and what it offers. We also spoke to Dr. Tomas Sluka, developer and founder of the startup CREAL, in an interview. Article based on CREAL whitepaper | Interview by Hanna Diewald

Subjective refraction has not changed significantly for 100 years. Opticians, optometrists and ophthalmologists normally use a phoropter or trial frame set to practice their conscientiously learned craft. But is this type of refraction really still up to date?

The new technology from the company CREAL, founded in 2017, offers completely new possibilities for subjective refraction. A prototype with the light field display technology is currently being tested by various players in research and industry.

The system is not yet on the market, but that is only a matter of time. Zeiss Vision Care has recently invested in CREAL and both companies signed a license agreement.

The idea

The Swiss startup was founded with the mission to develop a near-eye 3D display taking care of the user’s eyes. The developed light field display technology should enable users to have a healthy and natural visual experience of digital imagery, by supporting the natural behavior of the

human eye. This new type of display system provides correct focal depth to the digital content, and can place it at any optical distance and/or respectively apply arbitrary spherical, astigmatic or prismatic power to the projected image.

Furthermore, images with different corrections at different distances can be applied and displayed simultaneously. Any device built on such technology could be also made “intelligent” and controlled by a simple touch screen, allowing for an unassisted procedure carried out by the eye care practitioner and, if appropriate, the patient. Therefore, the company believes that digital near-eye light field display could bring a revolution to numerous optometric, optical and ophthalmological applications, especially in subjective refraction.

The digital light field display

Light field imagery is a genuine representation of how light exists in the real world. It therefore provides highly realistic digital imagery with natural focal depth, enabling the digital content to blend seamlessly with the real world, and removing any visual conflict causing eye strain and nausea.

The light field display technology projects a sequence of slightly different perspectives of a digital scene (the light field) to the eye. Each perspective/ image is projected through its corresponding virtual viewpoint placed by the user’s pupil. By sending more than 6000 in-focus images per

second, the full 3D digital scene is recreated in front of the user’s eyes. The digital light field technology is also suitable for displaying graphically rich content in VR and AR. CREAL already embeds it in its patented light field headset evaluation kits (Fig. 1.4).

Digital light field technology for optometry

Current eye examination procedures have not changed much in over 100 years; with eye care practitioners (ECPs) still using physical lenses and test charts in refraction. Optometry products based on the new digital light field technology can bring a significant change to the industry and can offer many advantages.

Fig. 1.1: Each perspective of the light field is projected to its corresponding viewpoint on the eye.

Fig. 1.2: Image perceived by the eye when the eye accommodates close (bird’s light rays combine on the retina).

Fig. 1.3: Image perceived by the eye when the eye accommodates far (tree’s light rays combine on the retina).

Self-contained,

space efficient and simultaneous displaying of different powers

The device based on the digital light field technology is fully self-contained. The displayed image originates directly in the device itself with optical distance reconstructed fully digitally.

The size of the device is to be further reduced in the future, resulting in a small, effective tabletop instrument or even a head-mounted VR headset.

Furthermore, different spherical and astigmatic power can be displayed simultaneously. Objects or images with different optical power applied can be shown next to each other in a single screen. This brings several benefits:

▶ The user can easily compare which image is seen best, because the user sees them simultaneously next to each other. For example, letters with a range of diopters are shown simultaneously.

▶ Simultaneous or comparative images projected at the same time (especially for astigmatic evaluation) give the user more confidence in their answer. ECPs might hear less often: “I am not sure”.

▶ The user can identify which is seen best, picks it and quickly moves to a finer refraction selection.

▶ The comparison between different powers next to each other allows for faster assessment than comparing one after another in traditional devices.

▶ The process can remove the need for initial measurement with an autorefractor.

Real-world images and instant change

of

digital content

The user is shown real-world images and any flat image, 3D object, or even animations can be displayed. This means:

▶ More relevant and recognizable scenarios can be displayed to evaluate refraction.

▶ A variety of different symbols or images, including 3D objects, can be used for children or adult patients for whom standard symbols might be hard to recognize/name.

▶ Application-specific symbols can be designed.

▶ Information can be displayed to guide the user through the procedure.

It is also possible to show users relevant imagery such as computer screens, mobile phones, and television. And images are seen at appropriate distances, all at the same time.

Additionally the shown content can be changed digitally. The device enables randomized permutation of Snellen chart letters' position and prescription for each measurement. This prevents users from learning the chart leading to more reliable testing procedures. Each patient and each measurement will be unique.

And the test procedure is very simple: with a click by the patient or ECP, new and specific images can be instantly changed, taking the eye test along a defined and automated route to determine the refraction. The change of content is instant (<1/30 s), similar to a change of picture on

the screen of a mobile phone. The same applies to the change of spherical or astigmatic power.

Flexible spherical power and astigmatic power

As the optical power is generated digitally, it is not tied to a set of preexisting lenses. Therefore, its range and fineness are not limited by a set of physical lenses. A major benefit is that any prescription (or comparative prescriptions) can be generated rapidly and not limited by physical lens combinations.

▶ Spherical power steps can be adjusted in increments: <0.1 D.

▶ Spherical power range is large (-15.00D to +12.00D)

▶ The same range applies to astigmatic power (-5.00D to +5.00D)

▶ Prismatic powers can be applied.

▶ Presbyopic prescriptions can be evaluated easily with near-field imagery.

Interactive and fully user-controlled and/or automated procedures

Since the device is based on digital light field technology, it can be controlled through a tablet or similar interface. This allows CREAL to design an interface that fully guides the user through the entire procedure.

▶ Automated procedures: no need for lengthy subjective assessments during the normal procedure.

▶ Multiple devices supervision by one staff member.

▶ Multiple procedures can be combined.

▶ Procedures can be entertaining (e.g. for children or patients with special needs).

▶ Measurement procedures can be updated over the internet, allowing immediate deployment of new procedures through the retail network without costly and time-intensive staff retraining.

▶ Specific tailor-made procedures can be designed for niche customers and markets.

▶ Other device input (autorefractor, lensometer) can be incorporated.

New classes of devices and use cases

All of the above and future advancements can allow for the development of completely new test procedures or even treatment procedures; for example: Interactive games to stimulate development focusing abilities, such as treating amblyopia/lazy eye.

But also, color vision screenings, binocular vision testing, visual fields examination, pilot or driver training procedures and much more. Future potential is not limited to simple refraction.

AR glasses and subjective refraction

Interview with Dr. Tomas Sluka

A new type of technology, the so-called light-field display, was developed to enable a completely new type of subjective refraction in future. Originally, the technology was only intended for the development of smart glasses, but in the process the focus of the young company shifted towards subjective refraction first. MAFO spoke with the developer and CEO Dr. Tomas Sluka about how this change came about and what potential the technology offers. By Hanna Diewald

CREAL was founded in 2017. Can you explain briefly how the idea came about to establish this company?

It started in 2012 when the first consumer virtual reality goggles started appearing. While trying them I found a horrible kind of eye strain in them. I realized the reason quickly: all those glasses have a display with a fixed focal plane and therefore the eyes are stimulated wrongly. I knew instantly that if this problem was not solved, they would never work for me. I found that the same problem affects a lot of people. Around 10% or 20% of people really cannot handle it and most people feel somehow sick ‒ not from motion sickness − but from the wrong visual stimulus that causes an accommodation conflict.

So, I started looking into research papers, patents and the industry but I didn't see any practical solution. I got my own idea that looked more viable to me. Then I made a display prototype at home, which worked better than I expected. This was the moment I said: okay, I will submit a patent, and I will start a company because this technology is a solution to a huge problem.

What kind of problems do you solve?

We basically eliminate two key problems. One is called vergence-accommodation conflict. It is about how the two eyes perceive depth and how each single eye perceives depth. If you have a conflict here, the brain evaluates it like seasickness.

The second problem is called a focal rivalry. This means for example, that if I want to touch some virtual object with my hand, but my hand and the object are at a different focal distance, then the eye has to change focus between the finger and the object in my hand. You can´t see both objects next to each other. And the third challenge is the prescription

correction. With our AR display, we can fix all of these problems. We integrate our display i n the temple of the glasses and make it work with any lens − also exactly the one you have right now. Then we layer a holographic film on it to realize the augmented reality.

You also want to revolutionize subjective refraction. How did that come about?

At the beginning there were no thoughts on vision care, but it turned out later that it was an almost inevitable consequence because the display can provide digital version of lens-based instruments. Then we understood that we can do a refraction testing instrument with the display. Our early bulky prototype, an evaluation kit, became the first thing we started delivering to vision care companies for testing.

What is the advantage for the subjective refraction?

It doesn’t depend on physical lenses unlike any other existing refraction method, that is limited by a set of lenses or a variable lens. The main difference to all other existing technologies is that the display can replicate the lens purely digitally. We just upload its shape in the software and you will see exactly what you would see through the physical lens ‒ but in a digital environment.

Furthermore, the display does not only project the real 3D world and real lenses. We can display whatever we want, like spaceship cockpit seen through an ideal progressive lens for example. It is also possible to show a comparison between high quality progressive lenses and lowquality progressive lenses for example. This way, we can improve the buying experience for customers tremendously.

Your technology allows patients to control the system themselves. Where do you see the distribution channels?

The first prototype is operated by the patients themselves. They have a clicker and they select what looks the sharpest to them the different corrections are shown next to each other or in a certain mixed form. Now, as you still need an expert to explain and guide you through the process, we plan to deploy it first at opticians and ophthalmologists, who are responsible for vision testing, depending on the countries regulations. However, the general idea is to make vision testing much more accessible. You can imagine that once the device is automated and fully certified as an automated instrument it will be the moment it can be deployed at schools, workplaces, small shops that currently can’t afford optometrist service.

Thank you for the interview. ◆

About MAFO – The Conference

Did you know?

MAFO – The Conference takes place for the 23rd time. With a few exceptions, it has been organized annually since the year 2000. First, it was co-organized by two optical trade journals and later on continued by former MAFO publisher Jörg Spangemacher.

Last year, 90 participants from the ophthalmic industry took part in the event.

In the early years, MAFO - The Conference was held in Paris before Silmo. But when the optical machinery industry chose Mido as its most important trade fair in Europe, the conference also moved to Milan.

Filtertech’s LGEN-PAL & Sustainability

Filtertech has been a leader in filtration and waste management in the United States for over 50 years and has served industries all over the world. Over the last 10 years Filtertech has brought their expertise in industrial filtration, waste management and sustainability to the eye glass manufacturing industry.

One technology Filtertech has been most proud of is their industrial process and waste water treatment. Many industries have waste streams or byproducts that contain hazardous materials that cannot be safely disposed of. The costs of disposing properly can be very expensive and make it difficult for companies to operate. The optical industry is no different, with many having issues disposing of alloy waste water and spent polish.

Filtertech adopted its large industrial process water systems and developed the LGEN-PAL series to make equipment smaller, more compact, and an affordable process of this technology. Furthermore, this series of equipment is broken down into a manual process, which is convenient and affordable. The manual LGEN-PAL system requires an operator to measure, turn on pumps, mixers, motors, and open and close valves, etc. We also offer a semi-automatic system that requires an operator to start and finish each batch but can let the system run automatically during the batch process. Then there is a fully automatic

system, which is designed to run continuously until the system runs out of material to process.

The LGEN-PAL equipment allows optical labs to process their alloy water and spent polish in house without having it sent away. It treats the hazardous material, not by spending lots of time and energy boiling or vaporizing the water, but by using a proprietary clay-based chemistry that encapsulates the hazardous materials in the water. This system can process 35 gallons of alloy water in 45 minutes or less. It can also process 3 gallons of spent polish while still processing 30 gallons of alloy water simultaneously in 45 minutes.

Unlike distillation, clay-based process water treatment is environmentally friendly, because it does not consume immense amounts of energy and time and does not emit fumes in the air. And when the clay is dry, it is safe to throw away. Please check out our LGEN-PAL series!

AI-based measuring – a holistic approach

Q&A with Gunter Schneider

Schneider has closed the loop of its smart and fully automated future lab, the Modulo line, by enabling holistic quality control – which is more integrated and smarter than ever. President Gunter Schneider explains how two AI-based innovations make this possible: Firstly, PMD Modulo ONE, an inline power measurement system, that allows for on-block measuring right after surfacing. Secondly, CSI-P Modulo ONE, the ultimate quality check that combines full-map power measurement with AI-based cosmetic inspection. The data directly feeds the system with important and quality defining information, leading to immediate logical actions.

Why are smart measuring systems essential for lens production?

Obviously, implementing measuring systems in a lens production lab will allow you to receive feedback about the product quality at a specific time within the production line. It can proof the quality of the final product to ensure customer satisfaction, but it can also help to improve the efficiency of the production itself and save costs by identifying and even preventing breakage. In general, a final check might be well-established, but in my opinion, it is still being done too often manually and too late in the process. Automated and smart measurement at an earlier stage would help to identify quality drifts and avoid breakage, which will save valuable resources.

How has SCHNEIDER

addressed this shortcoming?

To implement a holistic measuring system, we have launched two solutions with individual approaches that add to our fully automated lab of the future. Our smart devices will both check the quality of your product and point out the problems that cause any irregularities. Firstly, we have an on-block power measurement system that allows for in-line power measurement right after surfacing. Secondly, we also have a system that combines full-map power measurement with AI-based cosmetic inspection. Implementing both features offers high potential to save time, costs, and ensure highest product quality.

Why exactly does it need measurement in-line?

The logic of our full map PMD Modulo ONE is to implement an early warning system. It will provide immediate feedback, at the earliest moment possible. It automatically measures the diopter of a lens and thus it’s optical effect after surfacing. Any deviations – for example caused by worn tools or loose tape – will be detected before any further cost intensive subsequent processing steps are started on a faulty lens, such as cleaning, coating or edging. This will lead to significant savings in costs and production times. The on-block method allows for on the fly measuring and even facilitates rework – no deblocking needed.

To me, it is very important to mention that the smart system collects a variety of information, paving the way for smart trouble shooting with the help of the Modulo Control Center. Potential issues, such as problems with the chiller, will be identified before they arise.

What are the advantages

of the new cosmetic inspection system?

While for the longest time automating cosmetic inspection was considered impossible, this has now changed. Our fully automated system CSI Modulo ONE can analyze lenses and evaluate their surface quality with the help of AI. It reliably detects cosmetic defects, by screening the surface for irregularities, and characterizes and evaluates them. Based on the lab’s specific quality standards, the smart system knows what constitutes a go or no-go. It understands what kind of defects, in which combination, in what intensity and in which zones, is deemed acceptable.

Now, combining cosmetic inspection with power measurement in one machine is a real game changer: All quality defining aspects will be assessed in one go at the end of the production process. This makes CSI-P Modulo ONE a powerful tool to assure and comply with quality standards of outgoing goods.

What

are your future visions?

We at Schneider believe that beyond full-automation, AI will further revolutionize the ophthalmic industry. A huge amount of data can be useless, if not correctly classified and turned into useful information that leads to actions. AI can help make the best out of data and optimize processes at a high level. Instead of just becoming faster, ophthalmic labs will be able to grow smarter than ever.

This important quality check ensures that every lens not only meets individual prescription but also meets the highest visual standards, empowering labs to deliver perfection every time.

“Our primary goal is to enhance efficiency — producing more with fewer resources while achieving better quality in shorter time,” says Thorsten Wageman. “We aim to streamline every aspect of our operations to achieve consistent and measurable results. A&R equipment and technologies provide solutions that support our vision for the future.”

Automated cosmetic inspection transforms traditional methods to align with the future of lens production. This technology meticulously evaluates lens surfaces for defects, ensuring uniform quality throughout production.

Thorsten and Peer highlight the impact: “Manual inspection requires a skilled workforce and significant time investment. Since implementing A&R's total lens inspection prototype, we've already reduced inspection times while achieving higher accuracy. Last month alone, our return rates dropped by over 20%.”

Beyond efficiency, the A&R solution allows labs to allocate human resources to more complex tasks, empowering their employees and enhancing overall productivity.

The ophthalmic industry is not only about precision but also about adaptability. With shorter delivery cycles and increasing demand for customized lens solutions, labs must stay agile.

For Wetzlich, the adoption of A&R’s automated cosmetic inspection prototype marks the beginning of an exciting journey toward enhanced quality control. While still in its early stages, the results are already highly promising, with noticeable improvements in inspection efficiency and accuracy that pave the way for future advancements.

Moreover, A&R’s equipment provides valuable data insights, enabling labs to gain a deeper understanding of production trends. These insights not only identify defects but also help prevent them by addressing their root causes, fostering a proactive approach to quality control.

These analytics are powered by A&R's SPC (Statistical Process Control) software, which allows real-time monitoring of quality metrics and continuous improvement of production processes.

Advances in optics and ophthalmology worldwide | part 2

The impact of artificial intelligence (AI), virtual reality (VR), and emerging trends in digital therapeutics (DTx)

In part 1 of this article, you found an in-depth comparison of how various countries have integrated AI, VR, and digital therapeutics (DTx) into eye healthcare, including the in-store sales experience, spectacle lens selection, and more. In Part 2, you will learn about the general role of AI, VR, and DTx, their growing potential, and the regulatory framework for digital therapeutics. By David Benet Ferrus

Table 1: Download a comprehensive table with 17 countries/ regions and detailed information about regulatory frameworks here.

The Role of AI, VR, and DTx in lens design and customer experience

AI, VR, and DTx play crucial roles in enhancing lens design and customer experience (Cx). AI enables the analysis of individual visual needs, leading to the creation of personalized lenses that improve visual outcomes. By processing large datasets, AI identifies optimal lens configurations, contributing to more precise and effective designs[23] VR facilitates the design process by allowing real-time adjustments to lens dynamics in virtual environments. This capability enables designers to test and refine lens configurations, enhancing accuracy and efficiency. Additionally, VR can be used to provide customers with interactive experience, helping them visualize how different lens options can improve their vision.

DTx contributes to the customer journey by offering personalized therapeutic interventions that complement lens use. Applications such as visual training exercises and gaze tracking can be integrated with lens technology to enhance visual outcomes. For instance, DTx platforms can guide patients through exercises that optimize their use of progressive lenses, improving adaptation and satisfaction[24]

Digital therapeutics is a growing area in healthcare and technology

Digital therapeutics (DTx) is rapidly emerging as a critical component of modern healthcare, particularly in ophthalmology, where it enhances patient management and treatment outcomes. Recent market research indicates that the global DTx market is expected to grow significantly, driven by increased adoption of mobile health solutions and a rising demand for personalized patient care. According to a report by Global Market Insights (2024), the digital therapeutics market is projected to surpass $9 billion by 2028, with a notable emphasis on applications for chronic conditions and rehabilitation, including those specific to eye health.

As these technologies gain traction, they offer evidence-based interventions that can be seamlessly integrated into existing treatment paradigms, providing healthcare providers with powerful tools to improve adherence and patient engagement.

The impact of DTx in optics and ophthalmology is particularly noteworthy, as evidenced by studies demonstrating its effectiveness in managing conditions such as amblyopia, myopia and diabetic retinopathy.

Chances for more patient-centered healthcare

For example, recent trials showed that gamified DTx applications not only enhance visual acuity in children with amblyopia but also significantly improve user engagement compared to traditional therapies[25]

This personalized approach, utilizing real-time feedback and adaptive learning, underscores the potential of DTx to revolutionize patient care by making treatments more accessible and tailored to individual needs.

As regulatory bodies increasingly recognize and approve these digital interventions, the integration of DTx into standard ophthalmological practices is expected to accelerate, paving the way for a more patientcentered healthcare system that leverages technology to enhance outcomes and accessibility.

Regulatory framework for digital therapeutics

One of the primary objectives is to provide clarity and consistency regarding the regulatory frameworks for digital therapeutics (DTx), which vary across regions and countries. While each key region follows its own approach, ongoing international harmonization efforts are aiming to align regulatory standards globally.

In table 1 (QR-code on page 41), I present the latest available data to clarify the global regulatory landscape and the specific requirements that DTx must meet. This information is drawn from direct industry experience, insights from leading companies and regional regulatory bodies, as well as credible sources such as the DTx Alliance among others.

United States

The U.S. Food and Drug Administration (FDA) stands out in the regulatory landscape for digital therapeutics (DTx) by frequently advocating for digital sham-controlled randomized controlled trials (RCTs). This approach contrasts with many other regulatory bodies that often permit “treatment as usual” as a control in RCTs, with some allowing less rigorous studies or reliance on published literature for clinical validation.

While Real World Evidence (RWE) generally falls short of meeting marketing authorization requirements in jurisdictions necessitating RCTs, it may still be utilized for submissions involving DTx devices with established predicates in select markets, such as Southeast Asia and India. The FDA's regulatory framework plays a crucial role in shaping the development and deployment of DTx, fostering innovation while ensuring patient safety.

Europe

In Europe, regulatory authorities are increasingly focused on creating a harmonized framework for DTx within the context of the Medical Device Regulation (MDR). This regulatory landscape mandates that DTx be classified according to their intended purpose, with varying requirements for clinical evidence depending on their classification.

The European Medicines Agency (EMA) is actively working to streamline approval processes for DTx, facilitating faster market access while ensuring compliance with stringent safety and efficacy standards. However, challenges remain, particularly regarding reimbursement pathways, which are still being defined across member states.

Asia-Pacific

In the Asia-Pacific (APAC) region, regulatory bodies employ a risk-based classification system for software as a medical device (SaMD), significantly impacting the regulatory and clinical burdens associated with DTx.

Many markets in this region offer less stringent regulatory pathways for consumer health versions of digital health products that do not assert treatment or diagnostic claims. For DTx products that do make treatment claims, regulatory submissions typically necessitate clinical data, with variability in the nature and rigor of this data based on factors such as product classification, associated risks, intended use, novelty, and the endpoints employed − whether subjective (like patientreported outcomes) or objective (such as biomarkers).

While some countries, like Japan, impose strict requirements for clinical data from local subjects, the U.S. and South Korea demonstrate a greater degree of flexibility in considering relevant external data.

Africa

In Africa, the integration of AI, VR, and DTx is still in its nascent stages but holds considerable promise for addressing healthcare disparities, particularly in ophthalmology. AI-driven tools are being employed to enhance the diagnosis of prevalent conditions such as cataracts and glaucoma, while VR technology is utilized for training healthcare professionals.

Mobile-based DTx applications are being developed to deliver therapeutic interventions, such as visual training exercises for children with amblyopia, capitalizing on the increasing penetration of mobile technology across the continent. However, the region faces significant challenges, including inadequate healthcare infrastructure and limited funding, which hinder the widespread adoption of these technologies.

Unprecedent opportunities

In table 1 (QR-code on page 41) , you can see the regulatory framework for countries and regions at a global level. Overall, while significant progress is being made in the regulation of DTx across these regions, the evolving landscape presents both opportunities and challenges that necessitate ongoing collaboration among regulatory authorities, industry stakeholders, and healthcare providers.

In conclusion, the integration of AI, VR, and DTx into the fields of optics and ophthalmology marks a transformative advancement in healthcare. These technologies offer unprecedented opportunities for improving diagnosis, treatment, lens design, and patient engagement. As highlighted by research from leading institutions such as Stanford, Harvard, Johns Hopkins, and MIT, several critical trends are emerging

that underscore the future direction of these innovations. First, personalized patient engagement is becoming a cornerstone of modern healthcare, with DTx applications enabling tailored interventions that enhance patient adherence and treatment outcomes. The ability to adapt therapies in real time, as explored in AI-driven solutions, underscores the need for scalable DTx platforms that respond to individual patient needs. Furthermore, integrating these digital therapies into standard clinical care is essential to ensuring consistency and efficacy across practices. Guidelines and evidence-based frameworks for DTx usage, particularly in ophthalmology, are crucial as these technologies become more commonplace in clinical environments.

In parallel, the rapid growth of VR technologies offers significant potential to revolutionize medical training. Immersive simulations are already showing promise in enhancing surgical skills and improving patient outcomes. Expanding these training programs globally could address skill shortages, particularly in developing regions. However, these advancements bring with them new challenges, particularly in terms of data privacy and security. As DTx platforms collect and process vast amounts of patient data, the development of robust data protection frameworks that align with regulations like GDPR and HIPAA is imperative. These safeguards must be designed to protect patient information while fostering the continued growth of these innovations. Finally, ensuring equitable access to these technologies is a key concern. Collaborative efforts between governments, academic institutions, and technology companies are essential to bridge the gap in access to care, particularly in low-resource settings. Initiatives that focus on providing affordable access to DTx applications and training for healthcare providers can help address disparities in healthcare availability.

Conclusion

In summary, while the integration of AI, VR, and DTx holds the potential to revolutionize ophthalmology and vision care, the success of these

innovations will depend on sustained research, investment, and collaboration across the global healthcare ecosystem. By addressing the associated challenges − particularly in the realms of data privacy, clinical integration, and equitable access − the healthcare community can fully realize the benefits of these transformative technologies, ultimately improving patient outcomes and advancing the standard of care worldwide. ◆

Pressure in sales?

Avoid typical mistakes between marketing and sales

Misunderstandings between marketing and sales can lead to ineffective sales strategies. This is a waste of resources that could be better used. To put this “better use” into practice a good exchange between the two departments marketing and sales is essential. By

Dr. Michael Stiller

What is the ideal effect of marketing and sales on the customer?

Marketing is responsible for the first points of contact with a customer. It starts with the customer's learning process. Messages are communicated that ideally inspire the customer to act or trigger an intention to act at a later point in time.

Then sales comes into play. After marketing has set the initial stimuli, the sales activities give a push for the customer's purchase action. A product is purchased, or a contract is extended. And the sales team takes care of this. This means marketing measures prepare the ground and sales closes the deal at the end. Together, they must successfully guide customers through the customer journey. This means that marketing focuses primarily on generating awareness, interest and willingness to buy or pay for the product. Sales then gives a push for the action, i.e. the purchase of the product, by the customer.

Only through close cooperation between marketing and sales can the customer experience be optimized and the probability of a sale at the desired price increased.

Typical

problems in the collaboration between marketing and sales

In practice, however, marketing and sales often do not work together effectively. On the contrary: in many companies, tensions and communication gaps arise at the interface between marketing and sales.

A typical example

Sales comes under pressure because it runs the risk of not achieving its sales targets. This development is often only recognized so late that there is not much time left for an analysis. Why aren't our target groups buying? Are they not familiar with our product? Do they not know the benefits? Or are there even barriers to purchase?

In its distress, sales seeks support from marketing. A campaign must now be launched quickly to support the sale of the products. But where should marketing start? There is no time for a detailed analysis. This puts marketing under pressure. Under tension, the marketing team develops a campaign based on rather general information. The result: the campaign fails to have the desired effect.

Sales ‒ which has relied on the campaign's effectiveness ‒ comes under even more pressure and the relationship between marketing and sales deteriorates further.

Using insights from sales in marketing

How can marketing and sales work together effectively in this critical phase? First of all, sales should communicate early on when it needs support. Early warning indicators can help sales to recognize declining sales at an early stage and request support from marketing. If this happens, marketing and sales must work closely together. This is because sales gains valuable insights into customer attitudes towards the products.

Direct customer contact tells sales why customers are not buying the product. Marketing needs precisely this information in order to take these problem areas into account when developing campaigns. Marketing must have this exchange. After all, marketing is responsible for campaign development. They should ask the sales people the right questions and specifically request the information they need for an effective campaign.

For example, the following insights can be gained from sales:

▶ Is there too little brand awareness?

▶ Is the product perceived as too expensive?

▶ Do customers believe that the competition offers better products?

This is valuable information that sales receives through direct customer contact and that marketing needs for campaign development.

The conceptual development of the campaign should remain within the company and be carried out by the marketing department instead of being outsourced to agencies. After all, the company itself knows its customers best. To do this, marketing needs conceptual knowledge and an understanding of advertising mechanics.

The AIDA model (attention, interest, desire, action), for example, is ideal for working out which messages the campaign should convey. Is it about increasing awareness? Or should the desire for the product be increased? This is the only way to develop targeted messages and activate potential customers cognitively.

Conclusion

Marketing and sales must work closely together to successfully guide customers through the customer journey. If sales is under pressure, it should request support from marketing at an early stage. Marketing must then lead the process. It must ensure that all the necessary information is available from sales in order to develop an effective campaign. ◆

Pioneer Thomas Young

Physician, ophthalmologist, pioneer of modern optics and expert in hieroglyphics

With this scholar, it's hard to know where to start: British physician, physicist and polymath Thomas Young (1773-1829) is best known today for his groundbreaking work in optics and human vision. His discoveries have had a decisive influence on the modern understanding of physics, in particular the wave theory of light, as well as the functioning of the human eye. He was the first to explain accommodation, the three-color theory of color perception, astigmatism and calculated the contact angle of drops of liquid on a surface. What many people do not know about him: He was also a key figure in the decipherment of the Rosetta Stone, without which a translation of the Egyptian hieroglyphs would not have been possible. By

Silke Sage

Thomas Young after Thomas Lawrence (CC)

Early life and education

Thomas Young was born in Milverton, Somerset, on June 13, 1773. He showed an exceptional talent for science and languages from an early age. By the age of 14, he had already mastered several languages, including Latin, Greek and Hebrew.

Young began his formal education in medicine and science at various prestigious universities, including London, Edinburgh and Göttingen, where he completed his doctorate in 1796. His special interest in the human eye and the visual process developed during his medical training and laid the foundation for his later discoveries in optics.

The wave theory of light

One of his most important discoveries was the development of the wave theory of light. At his time, the so-called corpuscle theory of Isaac Newton dominated, which explained light as consisting of particles. However, Young was convinced that light had the character of waves, similar to sound waves.

In 1801, he carried out the famous double-slit experiment, which proved the phenomenon of interference of light and thus disproved the corpuscle theory.

In his experiment, Young allowed light to pass through two narrow slits close together, which ultimately created a pattern of light and dark stripes on a screen behind them. This can be explained as follows: the light waves overlap. Light stripes appear where the waves are amplified and dark stripes appear where they disappear. This was a simple but impressive way of showing that light behaves like a wave.

Young's wave theory was one of the most important discoveries in optics, as it paved the way for the modern understanding of light, which has both particle and wave characteristics. Later developments in the quantum theory of light are partly based on Young's findings.

The three-color theory of vision

In addition to the physics of light, Young worked intensively on the functioning of the human eye. One of his central works in this field was the formulation of the three-color theory of vision, which was later refined by Hermann von Helmholtz. Young published the theory that color perception in the eye is based on three different receptors that react to the colors red, green and blue. This theory explained for the first time how the human eye can produce the entire color spectrum from these three primary colors.

Young also recognized that the eye cannot have specific receptors for each individual color, but that different colors are perceived through the combination of signals from the three receptor types. This theory is known today as the Young-Helmholtz theory and forms the basis of our modern understanding of color perception.

The accommodation of the eye

Another important discovery by Young was the explanation of the eye's ability to accommodate. He was the first to correctly describe

that this process occurs by changing the curvature of the lens in the eye, allowing it to focus on near or distant objects.

This explanation was a decisive step forward in understanding the physiological mechanisms of vision and is still used in ophthalmology today.

Despite his significant discoveries in optics, Young did not stop making important contributions in other disciplines. His exceptionally broad range of knowledge earned him the reputation of the “last polymath”.

Elasticity and Young's modulus

In mechanics, Young introduced the concept of the modulus of elasticity, which was named after him as “Young's modulus”. This modulus describes the stiffness of a material and is still a fundamental parameter in materials science today.

Young showed that the elongation of a material is proportional to the force acting on it, a principle known as Hooke's law. His work laid the foundation for the development of materials physics and modern engineering science.

Wave mechanics and hydrodynamics

Young also worked on the fundamentals of wave mechanics and hydrodynamics. In particular, his work on waves in liquids and gases expanded the understanding of these phenomena and influenced subsequent research in these fields.

Young's equation, for example, was named after him. It describes the wetting of liquid surfaces using the contact angle.

Linguistic studies and hieroglyphics

In addition to his scientific achievements, Young showed great interest in languages and writing. He was one of the first scientists to make a significant contribution to the decipherment of Egyptian hieroglyphics.

After the Rosetta Stone was discovered in 1799, it was Young who made the decisive breakthrough in deciphering it by recognizing that the hieroglyphs used both phonetic and ideographic characters. These findings later helped Jean-François Champollion to complete the full decipherment of the hieroglyphs.

Medical work

In addition to his scientific contributions, Young was also a successful doctor. In his practice, he treated patients with all kinds of ailments, including eye diseases. His work on the anatomy and physiology of the eye was not only of a theoretical nature, but was also used in practical ophthalmology.

Today, Thomas Young is considered one of the most important scientists of his time, whose work revolutionized various fields of physics, optics and medicine. With his broad expertise, which extended to linguistics, he is regarded as a pioneer of interdisciplinary thinking and scientific innovation. ◆

Inclusive AI models: Be My Eyes announces collaboration with Microsoft

Be My Eyes announced that it is working with Microsoft to make AI models more inclusive for the over 340 million people around the world who are blind or have low vision. Be My Eyes is a company that connects people who are blind or have low vision with sighted volunteers and companies through live video and AI. Earlier this year, Be My Eyes highlighted the concern that the blind and lowvision community are being left out from the development of AI models. Today, disability is often underrepresented or incorrectly categorized in datasets used to train AI, which can limit the utility of the technology or even magnify bias. That should change now. Be My Eyes will provide video data collected through its platform to Microsoft for AI model training. The video datasets represent the lived experience of the blind and low vision community and will be used to improve the accuracy and precision of scene understanding and descriptions, with the goal of increasing the utility of AI for the blind and low-vision community. By incorporating accessibility data, AI can better serve diverse user needs, making technology more usable and beneficial for everyone.
