M dulo Center Imagine one single machine featuring all the technology to surface 80 lenses/hour, in just 72 sq. f t. (7m²). This is Modulo Center ONE. The compact 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 process technology, based on robust and reliable components proven in hundreds of installations across the globe.

The all-in-one surfacing center substantially saves time, running all processes simultaneously and perfectly synchronized – even milling and lathe turning. And with the chambers placed right next to one another, the smart automation transfers the lenses in virtually no time. There is no faster way to surface a lens.

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

Labs can now run larger scale productions even in small locations and under nonindustrial conditions. Little to no operator intervention is needed as the center works fully automated with all essential components on board.

Simply put: Blank in, surfaced lens out.

IOT: innovation and knowledge everywhere IOT recently presented their latest designs and technologies with attendees at Vision Expo East, MIDO, and Expo Optica Brasil. IOT scientists presented new scientific research at ARVO and EAOO congresses. The two years of near isolation caused by the COVID-19 pandemic prompted many companies around the world to analyze their current businesses and prepare for new opportunities in a post COVID world. IOT, a company dedicated to the research and development of ophthalmic lenses, decided at the end of 2021 to approach the next chapter of its history with renewed strength and enthusiasm. This new commitment

by IOT was evident in their expanded presence at Vision Expo East, MIDO, and Expo Optica Brasil. These fairs, held in the USA, Italy, and Brazil, proved to be a great opportunity for IOT to showcase its new corporate image and identity, new technologies and services, and a completely new portfolio of free-form digital lens designs.

What do we mean by a “perfect lens” and can we produce it?

What is and what is not possible in designing best form lenses.

There are four main aberrations which affect spectacle lens wearers. For two of them, designers have no simple method of control by modifying the surfaces of the lens, transverse chromatism and distortion – no matter what lens manufacturers promise in their marketing texts. So, what is and what is not possible in designing best form lenses? B y Mo Jalie

virtually the same (Fig. 10). ◆

Mo Jalie Another way of expressing the aberrations across the lens is by showing astigmatism and power error plots, such as those shown in figure 9 for point-focal and Percival lens forms. These plots show how the astigmatism and power vary from the optical center to the 40° zone of the lens. Note that if the astigmatism is made equal to zero across the whole lens there is still some power error, or, if the power error is made equal to zero across the whole lens there remains some astigmatism.

This last statement is true whether we make the lens with spherical surfaces or in aspheric form using freeform technology So, in the light of these facts concerning the off-axis performance of spectacle lenses, I will re-examine some of the marketing statements concerning their performance.

Blue light Facts and trends What is light? This question was answered by Albert Einstein in 1905 in his treatises on electromagnetic radiation with dualism. The Copenhagen interpretation states that all radiation has both wave or particle character. The electromagnetic spectrum ranges from extremely long-wave radio radiation, with wavelengths of several meters up to kilometers, to high-energy short waves, gamma radiation. The part of the radiation which can be processed by our eye is called visible light, ranging from wavelengths of 390 nm to 780 nm. By Fritz Paßmann

Kohlrausch break In normal brightness, the cones are more suitable for seeing because the rods are too sensitive. In darkness, the more sensitive rods are more suitable. Therefore, there is not only an increase in the sensitivity of the sensory cells, but also a change from one type of sensory cell to another: from the cones to the rods. Since the rods adapt more slowly than the cones, their stimulus threshold does not decrease continuously, but remains constant for a certain time. Namely, at the point where the minimum threshold of the cones is reached. Only when the stimulus threshold of the rods has reached this point, it starts to decrease further due to the further adaptability of the rods. So here is the transition from cone to rod vision – also called Kohlrausch break.

Dark Adaptation.

▶ “Have your eyes checked for any opacity or onset of cataracts.

Scattering on a cloudy eye lens also impairs vision and increases glare.”

▶ “I recommend slightly tinted lenses (brown 12%/UV420), which reduces the amount of light that is scattered, thus increasing contrast”.

What is blue light?

I would like to remind you of the classic line in Rambo III: “What does this one?” Rambo: “It’s a blue light.” “What does it do?” Rambo: “It turns blue.”

There is a lot of discussion about the hazards of blue light. As always, there are two sides to it: both a curse and a blessing.

to the spectral composition of the light, spherical aberration also has an effect, i.e., peripheral rays are refracted more strongly than rays close to the axis. In the eye system, an interaction of two refracting surfaces of the cornea and two refractive surfaces of the eye lens can also result in a spherical aberration in the “plus” direction. In general, higher order aberrations increase with a widening of the pupil diameter in the dark. To obtain an accurate analysis of these errors, the use of a wavefront aberrometer is recommended. Another issue in the development of night myopia is the resting state of accommodation.

Where there is a severe loss of contrast and in the absence of a fixation point, the accommodative system settles on an adjustment point 1-2

meters in front of the eye, in extreme cases of as little as 50 cm. This corresponds to a refractive value of 0.50 up to 2 D. This physiological component varies greatly from individual to individual and is difficult to measure. A tip for opticians is to give their customers binocular visors with sph -0.25 D and -0.50 D and a super antireflective lens, or a UV420 with a blue mirror coating. Some people will certainly notice the difference in twilight.

IT in the Lab Essential foundation with need for standardization Nothing works in the modern lab without IT, even if its central role sometimes gets lost in the background.

LensWare is one of the few companies on the market that concentrates on software and services exclusively for the ophthalmic industry. The system house aims to set a worldwide standard for Enterprise Resource Planning (ERP) complete packages.

while not losing sight of its own stability. If you can no longer “modernize” your own systems, death is inevitable. In addition, perfect support is a central issue. This can only be organized with an appropriate team.

We see a tendency to map all processes entirely automatically with a minimum of work force, in order to be able to concentrate fully on the customers, i.e. on the opticians.

Our industry is strongly driven by IT solutions. Everything is supposed to be interconnected. There are new developments in products and lab equipment, but the central issue is a stable and development-ready hardware and software solution with investment security and a fair price-performance ratio. Sometimes, however, the decision-makers do not understand the correlations at all. One problem with interconnectivity is the free-form technology itself, which is quite complex. And there are always new suppliers emerging in the market, who need to be integrated. The second problem is the supply chain, i.e. end to end, the chaining of order processes.

You have to imagine this like complicated dictionaries in which the connection of the product portfolios of these companies is translated among each other in such a way that what one automatically feeds to the other is also delivered as a product.

High quality data – for successful AI projects and positive corporate culture Artificial Intelligence (AI) is still considered a promising technology that can drive the innovation engine.

Many areas, such as medicine and healthcare, but also trade, transport, industry and administration, are finding revolutionary uses for AI. Expectations for AI are high; after all, innovative courage wants to be rewarded. The "Future of Health" study by Roland Berger[1] shows: AI as a technology is predicted to cause the greatest impact in healthcare by 2026, closely followed by sensor-based monitoring, which can also lead to even more accurate analyses with the help of AI.

type best fits the predefined question.

However, the systems and also their analyses can only be as good as the underlying data basis, the definition of the problem in connection with the selected model. The underlying algorithms are developed by humans who are subject to cognitive biases or prejudices. These algorithms, in turn, are presented with data sets for training, which have also been selected by people who are not free from prejudice and value, and patterns are derived from them. This "bias" can lead to limited analyses, or even to discriminatory or racist results. Everything that the AI is supposed to learn must be taught to it based on the training data – and since, for example, the development team is not

always diverse and thus brings in different aspects, special care must be taken here.

Creating a solid database step by step Data is therefore the critical foundation for the success of any AI project. When selecting test and training data, project managers must ask themselves three questions: What data and in what quality do I need for my use case? Which data and data sources are available to me? What additional data do I need?

If the data is not yet available, it must be collected again within a specified period or obtained from external sources, such as open-source sites or so-called data marketplaces. Data protection aspects must of course be taken into account.

There is also the option of selecting models that can be trained

with little data – however, this requires the support of data scientists who have the appropriate knowledge of models, influencing factors and training parameters. A third option would be to use synthetic, i.e. generated data.

managers must then carefully check whether the data modified in this way is still meaningful enough for training. When collecting new data, the permission of the respective person could be obtained in accordance with the relevant data protection regulation (e.g., GDPR in Europe). Collaboration with project partners and the use of the cloud for data storage require special attention in terms of data protection. If companies make use of synthetic data, they have to be correctly distributed according

to the problem and map a representative cross-section of the real data to be expected. Once the AI has been trained with synthetic data, the step into application with real data requires close validation and monitoring. The guiding principle "The AI can only learn from the fed data and patterns!" must always remain in mind to avoid negative learning effects.

CLOSING WORDS

Efstathios Efthimiadis – a music loving tech expert Efstathios Efthimiadis works more in the background than in the foreground of Eyepress, MAFO's publishing house. He joined the publishing house 15 years ago and looks after everything to do with technology, production of print products and digital strategy. This starts with the magazine and catalogue productions in pre-press and ends with the organization of the daily workflow in the company. For him, the topic of digitalisation is a core issue. As the person responsible for smooth technical processes, he knows only too well how quickly technology and products can change. and keeps an eye on the digital progress in the company. In his free time he enjoys listening to music and spending time with his family. He also likes to explore the hidden beauties of the Ruhr region on his e-bike.

OUTLOOK

Did you know how the larvae of Platynereis dumerilii “see”?

Platynereis dumerilii is an annelid worm that belongs to the class Polychaetes. This species is a living fossil that has lived virtually unchanged for millions of years on the coasts of temperate and tropical seas. The larvae of marine invertebrates have the simplest eyes in the animal world. These so-called eyespots consist of only two cells: a photoreceptor that captures light and a pigment cell that shields the photoreceptor to one side. The larvae of the annelid Platynereis dumerilii each possess two eyespots and a cilium with which they move about. When an eye spot is illuminated, the photoreceptor cell sends the signal via a nerve cord to the surrounding cilia. These then change their beating frequency and the water flow around the larva changes. The larvae, which move forward in a helical fashion, are thus deflected in their direction and move toward the light.

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

Highest throughput meets smallest footprint – LCU Modulo ONE takes industrial cleaning to the next level, offering the same cleaning power as larger solutions but in a compact fully-automated inline unit. Utilizing the proven SCHNEIDER technology, it cleans both sides of the lens.

The all-in-one surfacing center substantially saves time, running all processes simultaneously and perfectly synchronized – even milling and lathe turning. And with the chambers placed right next to one another, the smart automation transfers the lenses in virtually no time. There is no faster way to surface a lens.

LCU Modulo ONE’s new process logic facilitates intense and thorough cleaning despite its compact design. Labs can choose between a two or three cleaning station setup plus drying station. The brush cleaner effectively removes even prints and adhesive residues, preparing the lens for dip or spin coating.

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

LCU Modulo ONE comes with a loading and unloading robot on board. The fast transfer of the lenses results in shorter cycle times and superior throughput.

Labs can now run larger scale productions even in small locations and under nonindustrial conditions. Little to no operator intervention is needed as the center works fully automated with all essential components on board.

Simply put: Blank in, surfaced lens out.

Its affordable price and low cost per lens ratio make the LCU Modulo ONE a sound investment for any lab.

Highest throughput

One auto blocker covering virtually all of a labs’ blocking requirements at highest speed. With CCU Modulo ONE, SCHNEIDER introduces the only auto blocker today with automated block size exchange and achieves unprecedented efficiency in blocking.

Time-consuming manual changes are a thing of the past. CCU Modulo ONE has multiple block sizes – a minimum of three and up to six – readily available. And the best part: The exchanges are carried out automatically and without increasing cycle time.

2022 marks our 100th anniversary. While this achievement demonstrates our commitment to and understanding of the lens manufacturing market, our focus continues to be the future success of our customers. We strive to achieve this by delivering innovative optical manufacturing solutions to improve the quality of life around the world. We owe our longevity to our customers, suppliers and employees we’ve worked with over the years.

With the added flexibility, CCU Modulo ONE solves a well-known problem: Inefficient block size distribution and poor machine utilization. For any lab size, a wider range of blocking requirements can be met with a smaller number of machines.

The proprietary lens measuring unit guarantees perfectly oriented lenses.

An intelligent fill control provides highly consistent and precise fillings – no under or over fillings. The alloy and block pieces can be refilled during operation.

It’s time to celebrate this incredible milestone. Visit us during Vision Expo East (New York), Laser World of Photonics (Munich) and MIDO (Milan) to cheer for the next 100 years!
