HSC m dulo From the freeform pioneers comes a new one-of-a-kind generator that excels on every level. With an added performance of more than 50%, HSC Modulo ONE is not just a little bit better but a revolution. It is virtually the power of two generators in ONE and forms the very heart of the Power Lab of the Next Decade – Modulo ONE. What makes HSC Modulo ONE so exceptionally fast? It is built on a brand new kinematic concept facilitating even faster process times. The high-performance generator relies on the proven two-motor concept featuring the most powerful XS-Tec motor for maximum dynamics and highest quality. The proven RS-Tec motor is known for its high robustness and provides added versatility. A new ultra-fast workpiece changer transfers the lenses and facilitates shortest chip to chip times. The result is insane generating speed and performance at the same great lens quality you know from SCHNEIDER generators.

Ultimately, HSC Modulo ONE provides significantly increased throughput in an even smaller footprint than before. Get the power of two generators in ONE. Eyepress Fachmedien GmbH Saarner Str. 151 45479 Muelheim a. d. Ruhr 66527 Germany

CoreTBA: The Block-less Freeform lens production system by MEI CoreTBA is the perfect solution for the entire digital lens generation process. This fully integrated equipment represents a game changer in the industry and a revolution in the surfacing field. With its Block-free system, for the first time in history, labs can avoid using tapes, blocks, and wax, or Alloy. This means that it’s not necessary to have taping, de-taping, blocking, and de-blocking machines in the production line anymore. Moreover, with its Dry Cut technology, the CoreTBA doesn’t need a water filtering system, which helps you save money and protect the environment. All processes, from the digital generation to engraving, polishing, and washing, are integrated into one unit with the smallest footprint on the market. In order to achieve a short machining cycle, all processes occur in parallel, and every section of the unit is fed by a tray conveyor system and digitally controlled loading arms. Visit www.meisystem.com

Coburn Introduces New Digital Lens Processing Platforms Coburn Technologies, a leading provider of ophthalmic lens processing systems and ophthalmic instruments, in continuation of their dedication to advancements in eyecare, has introduced new technology to kick-off their 70th anniversary. The NEXUS Digital Surfacing System leverages the technology in the acclaimed Cobalt Digital Lab to produce high quality digital RX lenses. The system includes the NEXUS DGT Digital Lens Generator and the NEXUS DP Digital Lens Polisher. Each system represents a significant upgrade from its predecessor. “The Cobalt Surfacing System was introduced in 2018 and over the years we saw an opportunity to design an even better platform which we have now delivered in the form of the NEXUS system,” stated Coburn Technologies, President, Alex Incera. “This result was years in the making to ensure we could deliver an even higher performance system.” Labs can expect a processing speed that is 50% faster than the Cobalt NXT Lens Generator.

Lab Management SPOTLIGHT

10 things you should know about PFAS The regulation of “Forever Chemicals” In 2023, the much-discussed ban of approximately 10,000 substances ‒− so called PFAS (per- and polyfluoroalkyl substances) − already made big waves in the European Union. Now there are also initial plans to regulate PFAS in the USA − but the potential ban is polarizing.

On the one hand it is about protecting people and the environment, on the other hand a blanket ban would affect thousands of everyday items and processes, some are even vital. Be it medical products, refrigerators or heat pumps. Many details about the ban on “Forever Chemicals” are still unclear ‒including the extent to which the laws will later affect ophthalmic products in general and specifically medical devices. However, 10 interesting details about PFAS and their regulation can be found here.

1.

What are PFAS? PFAS are a group of substances that comprises an estimated number of more than 10,000 different substances. PFAS do not occur naturally and have only been produced and used since the late 1940s. Chemically speaking, the organic compounds consist of carbon chains

of different lengths in which the hydrogen atoms are completely (perfluorinated) or partially (­polyfluorinated) replaced by fluorine atoms.

Those chains of linked carbon and fluorine atoms are among the strongest bonds in organic chemistry.

This is where the name “Forever Chemicals” comes from. PFAS are extremely durable and do not simply degrade in the environment. However, it is precisely this durability and special properties that make PFAS interesting for many products.

Best-known representatives of the PFAS group The best-known representatives of the PFAS-group are PFOS (perf luorooctane sulfonic acid) and PFOA

(­perfluorooctanoic acid). They have been produced and used since the 1950s. Most toxicological and other scientific information is available on

3.

In which products do PFAS occur?

In general, PFAS can be found in a wide range of different products, both in industry and in consumer goods. Due to their special properties such as stability as well as water,

grease and dirt-repellent properties, they are in demand in many products.

These include pans, shampoos, baking paper and dental floss, but also medical implants or heat pumps – this list could be continued endlessly.

5.

What is the problem with PFAS? PFAS are not acutely toxic chemicals. Using a Teflon frying pan or wearing a Gore-Tex rain jacket is not dangerous at first, but the accumulation in the body via water and food.

Studies on larger populations indicate that certain PFAS can damage the liver, the hormonal and immune systems, disrupt fat metabolism, impair the effect of vaccinations, result in lower birth weight, reduce fertility or cause cancer.

Criticism of the blanket ban Some industry representatives criticize that a general ban makes little sense. Instead, it should be looked at where PFAS could realistically be replaced and where

of creating simultaneous myopic retinal defocus during both distance and near viewing.

In uncorrected myopic eyes, images are formed in front of the retinal plane, leading to blurred vision. To correct myopia, standard single vision negatively powered lenses are prescribed to shift images onto the retinal plane. However, the peripheral defocus theory suggests that the use of standard single vision lenses results in images falling behind the retinal plane in the peripheral retina (instead of on the retina).

Different studies have hypothesized that inducing peripheral hyperopic defocus, as standard single vision lenses do, provides a stimulus for axial elongation and the consequent progression of myopia. Also, experiments in animals have shown that myopic defocus induced with positive power in the peripheral retina reduces axial elongation.[4] For that reason, the lens with MPDL technology has been specifically designed to fully correct the refractive error at the fovea while inducing

The study was done in a sample of 83 children divided in two groups: 42 children wearing standard single vision lenses and 41 children wearing the lenses with asymmetric myopic peripheral defocus during 12 months of follow-up.

Results of the study showed that using the lenses with MPDL technology reduces axial length growth in comparison to the use of standard single vision lenses. Specifically, the growth of axial length was 39% less in the group wearing the lenses with MPDL technology than in the control group wearing standard single vision lenses after 12 months of follow-up.[9] Regarding wearability, lenses with MPDL technology scores similarly Fig. 3: Axial length increase (mm) after 12 months of follow-up for a standard single vision lens in comparison to lenses with MPDL technology.

Every diopter counts ‒but what to do when the aids are missing?

An interview about myopia treatment options in the US with Dr. Ashley Tucker Every diopter counts and every child counts, state experts around the world when talking about myopia management in children. But what to do when there are simply no products approved for myopia treatment? This is the challenge facing ECPs throughout the USA. The third largest country in the world has so far only approved one single contact lens for myopia management. A scenario that has become unthinkable in Europe, where spectacle lenses for myopia management are sprouting up everywhere. MAFO wanted to find out more about the current situation in the USA and its impact. We spoke to a woman who describes herself as a myopia management enthusiast: Dr. Ashley Tucker. For years, she has been fully committed to ensuring that myopia management aids get finally approved in the US. And she has been appointed recently, as one out of four ambassadors for the education, outreach and practice-building initiatives of the World Council of Optometry (WCO), in partnership with CooperVision. By Hanna Diewald

Dr. Ashley Tucker Dr. Ashley Tucker graduated from the University of Houston College of Optometry where she also completed a cornea and contact lens ­residency.

Dr. Tucker is a partner at Bellaire Family Eye Care and The Contact Lens Institute of Houston and she is also a Visiting Assistant Professor at the University of Houston College of Optometry.

Dr. Tucker spends the majority of her clinic time managing patients who are in need of specialty contact lenses or myopia management and she has the honor of speaking on behalf of several contact lens companies on these topics. In addition, Dr. Tucker is a council member of the Contact Lens and Cornea section the AOA, a member of the advisory board for GPLI, and serves as the Public Outreach Chair for the Scleral Lens Education Society.

Lab Management TECHNOLOGY

A state-of-theart technology for photochromic lenses The history of ColorMatic Photochromic lenses by Rodenstock have a very long history. For more than 55 years now, the product has been continuously improved. The primary development goals were always the same: rapid reaction kinetics in lightening and darkening, an almost transparent lens indoors and a comfortably darkened lens in the sunshine. Thanks to an innovative compound technology, the lenses are now almost perfect and exactly at this high level the company has taken a surprising step. From now on, independent lab partners will have access to the ColorMatic technology as well as to ColorMatic as an independent technology brand. By Franz-Josef Achatz

Through the high degree of independence of this brand, Rodenstock supports lab partners in the individual implementation of ColorMatic® according to their needs. As a strong partner and independent provider, Rodenstock offers them the highest quality, extensive experience in production, as well as support in marketing and sales.

What does the ColorMatic® portfolio look like?

The ColorMatic® portfolio is uniquely diverse. In addition to ColorMatic® X, we also offer ColorMatic® 3, which boasts impressive performance and intense darkening, along with a wide selection of indices and color variations. Completing the portfolio is ColorMatic® Sun 3, an intelligent sunglass lens with contrast enhancer. As we are constantly working on further developments, we aim to grow together with our lab partners and continue to strive towards supporting the needs of spectacle wearers with the highest level of innovation and the best products in the future.

What you see is what you hear EssilorLuxottica launches first hearing aid glasses According to the World Health Organization (WHO), one in four people worldwide is expected to have hearing problems by 2050. At the same time, the undersupply in the hearing aid market is serious. One reason for this is that hearing systems are often associated with a lot of stigmatization. For example: “Anyone who wears hearing aids is old”. Even though this prejudice is far from reality.

Therefore, the industry giant EssilorLuxottica now wants to address this issue in a special way: The company's first hearing aid glasses will be launched on the market in fall 2024, The group is thus entering completely new territory in the hearing acoustics industry.

An invisible hearing solution In February, at the Mido trade fair, MAFO editors had the chance to test the new hearing glasses live, even before the official launch. “We are talking about glasses with an invisible integrated hearing solution,” explained Stefano Genco, Global Head of Super Audio and Nuance Audio, at the EssilorLuxottica booth.

And indeed, the frame does look very similar to a standard acetate frame. The technology, such as various microphones and two loudspeakers near the ears, is invisibly built into the temples. Individual power lenses can be fitted as usual by any standard lens manufacturer.

Nuance Audio comes with a wireless charging pad for easy recharging. It takes around 2.5 hours to charge fully and the estimated battery life is around eight hours of typical usage in a noisy environment.

The hearing aid glasses are available on the market in two colors, with two different temple lengths and in three sizes (48, 54 and 56). “The biggest one is specially addressed to the US market, where we will launch Nuance Audio first,” explained Genco.

The technology and how it works For the user, the hearing aid glasses work very simply.

inclined people who would otherwise be reluctant to wear a hearing aid.

It helps to introduce more people to the world of good hearing and perhaps also to arouse enthusiasm for other hearing aids, which nowadays offer an incredible number of technical possibilities and are often so small that they disappear almost invisibly behind the hair and are not even noticed by the other person.

The launch The first launch of the glasses will take place in the fall in the USA. The glasses can be purchased without a medical prescription, but the company is working to allow partial refunds even if it is too early to comment at this stage.

There are different requirements for this in each country. For reimbursement in some countries the glasses would have to be able to be adapted to the wearer's individual hearing curve, something the company is working on. The technology will therefore become even more attractive over time. However, there are many more requirements and they differ from country to country.

Due to the special technology, Nuance Audio will not be cheap so that partial reimbursement by health insurance companies would probably make the product attractive to a large proportion of the population. This is also the situation with hearing aids, as the sophisticated technology of those products has its price.

Ultimate goal: destigmatization In any case, the official launch of the hearing aid glasses is eagerly awaited. This is also because EssilorLuxottica's vertical structure means that various optical retailers are now also part of the group and EssilorLuxottica is not only the manufacturer and supplier of the hearing glasses, but also the “seller”.

It will also be interesting to see how the hearing aid glasses will develop technically and how the version that is ultimately launched in Europe will be equipped.

A destigmatization of hearing aids and hearing loss would be desirable in any case. After all, hearing can be “unlearned” in comparison to sight. It is therefore highly recommended that hearing aids are fitted as early as possible, when the hearing

Striving for innovation A visit to Optovision in Langen Thousands of spectacle lenses roll off the Optovision production line every day. The ophthalmic lens manufacturer has won numerous awards for outstanding performance in the areas of quality, service and more, over a period going back 45 years. Despite this ‒ or rather because of these qualities ‒ its image needs to be constantly reinvented. Their new brand image is designed to make a more high-quality, technical and innovative impression on customers.

Keen to demonstrate how this can be achieved on site, the manufacturer invited MAFO to visit them at Langen in Hesse (Germany), where we were able to take a look at the production facilities (Part 1) as well as learn more about the new corporate image, new products and the opticians' desire for more innovation (Part 2).

For the next operation, anti-reflection coating, all lenses are placed in so-called calottes, in readiness for the high-vacuum coating process (Fig. 6). Here the anti-reflection coating – and any other special coatings – are created by vaporizing a wide variety of materials, such as quartz, titanium oxide, etc. which are then deposited on the lens. The lens is now finished. It is checked one last time before being sent to the customer via Transmed; at least if it does not need to be edged.

Because a not inconsiderable proportion of the lenses – up to 70% Böttner estimates – undergo a further process: distant edging.

Where requested by the optician, the lenses are fitted into the appropriate frame before they are finally allowed to leave the large halls.

Generation Z What awaits the labor market?

Current studies show that with the so-called Generation Z, young people are currently entering the labor market who have completely different values and expectations than their predecessors. As a result, they pose completely new challenges for the HR sector − but also new opportunities and possibilities.

For example, there are many great-looking projects that have been designed without taking the target group's world into account. HR staff often try to mix new technologies with familiar selection processes.

However, it is more effective to establish new processes and then find suitable measures. This avoids expensive experiments that look good on social networks but are not reflected in qualitative applicant numbers.

HISTORY

Visual acuity testing on a beer mat Even in ancient times, visual acuity testing was one of the most important tasks when choosing a profession. Up until the Middle Ages, it was just a simple eye test, with no numerical assessment; it was enough to recognize a constellation in the sky, a target in the landscape or to distinguish a row of trees. Recognizing the church clock was also a popular eye test from the 16th century onwards.

It was only with the increased demands on visual acuity, for example in shipping, that it became necessary to standardize eye tests and, above all, to make them more precise before a captain was entrusted with a ship.

watchmaker, as visual aids such as glasses or, more recently, contact lenses have only been known since modern times and were not affordable for everyone.

At the latest with the industrialization and further development of transport and the beginning of motorization, it became necessary to standardize visual acuity tests and thus make them comparable. With the introduction of the meter, which was introduced internationally in 1799, the refractive anomaly became definable in diopters.

The official visual acuity tests were now available at the ophthalmologist´s practice, the optician´s store or at the examination office. It was only in advertising that original eye tests such as the one on the picture for near vision could still be found.

Today, all visual acuity tests are internationally standardized, and their values are defined in decimal numbers or fractions. Luminance, surroundings and font size are clearly defined. Color vision has its own history; it was

OUTLOOK

Closing with good news!

“We can almost always prevent blindness from ROP” Retinopathy of prematurity (ROP) – a vascular disease of the retina that is limited to premature infants – is a leading cause of blindness in children. But there exist significant disparities in outcomes between high-income and low-income countries, partly due to insufficient access to ROP screening.

However, artificial intelligence (AI) technology has now been shown to accurately and independently detect 100% of severe cases of ROP. This AI could therefore expand global screening and thus also sight-preserving treatment for ROP. “ROP is the leading cause of blindness in children in the U.S. and around the world, and perhaps the most solvable problem among many in global efforts to reduce preventable blindness,” said the study’s corresponding author, J. Peter Campbell, “Although we cannot fully prevent ROP, we can almost always prevent blindness from ROP.”

DBX m dulo With DBX Modulo ONE, SCHNEIDER debuts a powerful and fully automated new lens deboxer for high throughput, 24/7. The innovative technology unpacks all common kinds of boxes and materials – cardboard, blisters, even sleeves – damage-free with a clean process. It requires a minimum of energy and effort.

After swiftly identifying the type of box, DBX Modulo ONE opens it “naturally”: It unfolds, takes out and unwraps, entirely without touching the lens surface.

SCHNEIDERs eco-friendly process avoids cutting or burning the material using sharp blades or high energy lasers – no cutting particles or dust and no fumes.

All waste material is separated and collected individually to simplify recycling and further increase sustainability.
