Sustainable Processes TECHNOLOGY

UV curing and the impact of free radicals on human health About the UV curing technology and its debut in the ophthalmic industry The technology of photoinitiated polymerization, known since ancient Egypt, is widely used in various industries, and in the 20th century it gained huge importance in the paint industry of Europe: back in 1967, a progressive industrial technology for curing by that time with ultraviolet radiation (UV radiation) of unsaturated polyesters (the most common materials at that time) was proposed. The main advantage of the process then was a significant reduction in the time for obtaining the finished coating. By François Breton

Significant improvements have been achieved in the design of UV curable coatings with the introduction of nanofillers and vinyl silane monomers, leading to a much higher abrasion resistance level and a better compatibility with AR coatings.

this region as the safest to use (lowest energy).

▶ The UV-B region (280 to 315 nm) generally receives its classification due to its properties as a transition region. While most UV-A radiation does not have significantly damaging biological effects, the higher energy UV-B radiation does; you know this effect as sunburn.

▶ Many of the earliest UV-functional materials employed absorption in the UV-C region (e.g., benzophenone-type initiators). Wavelengths in this region (200 to 280 nm) are often referred to as “germicidal” wavelengths due to disruption of DNA processes at the cellular level.

A further distinction of the UV-C region is that these wavelengths are almost completely absorbed by the ozone layer while UV-B radiation is only partially absorbed (thank you ozone layer!).

The monomers and oligomers are used to tailor the properties in both the uncured and final cured state. Additives such as viscosity modifiers may be added to aid processing. The photoinitiator molecule is the key to understanding the resin system’s capabilities and requirements. UVcurable resins are best classified by photoinitiator’s reaction mechanism

In the UV polymerization process you have complete control over the number and rate of free-radicals generated at any point in the process.

Free radicals can only be generated upon absorption of UV radiation and the source of UV radiation is defined and controlled by the process.

Why can UV curable coatings generate cancers?

As we have seen in the previous chapter, once in contact with UV light, the monomers will turn into free radicals. Those free radicals are the main responsible for cancers, especially for skin cancers. Having carried out my PhD experimental work in a laboratory specialized in free radical polymerization, I would like to pay tribute to some of the researchers who dedicated their life to that chemistry and who all died from cancers related to that chemistry: Prof. Michel Bartholin (19412006), Prof. Jean Guillot (1937-1999), Prof. André Revillon (1943-2010) and Dr. Christian Graillat (1947-2017).

In the ophthalmic industry, with the growing usage of polycarbonate as a lens ­material predominantly in North America, there was a need for protecting the lens surface from scratches, hence the need for an abrasion resistant coating.

What happens in human body Excess generation of free radicals may overwhelm natural cellular antioxidant defences, leading to oxidation and further cellular functional impairment. In reality, the oxidative damage potential is greater, and thus there is a constant small amount of toxic free radical formation, which escapes the defence of the cell. Oxidative stress is proportional to the concentration of free radicals which depends on both processes (formation and quenching). The degree of oxidative stress experienced by a cell will be a function of the activity of free radical generating reactions on one hand, and the activity of the free radical scavenging system on the other.

UV-induced generation of reactive oxygen species in the skin develops oxidative stress, when their formation exceeds the antioxidant defence ability of the target cell (Katiyar and Mukhtar, 2001). Although the skin possesses an elaborate antioxidant defence system to deal with

UV irradiation depletes the catalase activity in the skin and increases protein oxidation (Sander et al., 2002).

Damage done to genes in the DNA may result in genes that produce ineffective proteins; some of these proteins are watchkeepers over the DNA integrity.

Some of these mutations may involve genes known as tumor suppressor genes. These genes code for proteins that function to repair damages in DNA or cause cells that are damaged beyond salvage to be removed through a process of apoptosis (programmed cell death).

Most often, it is a series of mutations in tumor suppressor genes and other genes that leads to the formation of a cancer cell.

Film lamination Shifting the coating paradigm Hard and AR coatings are key to producing premium lenses – and having these steps in-house allows labs to control quality and delivery times, as well as generating revenue and profit. However, building and running a coating facility can be a formidable challenge, especially for smaller labs and for those starting a completely new Rx manufacturing facility that includes coating.

and running – the added process time, which can range

from three to ten hours depending on which technology is chosen.

Until now, that is.

A new approach Satisloh, a leading optical manufacturing technology provider, recently introduced a completely different way of coating ophthalmic lenses.

One that makes entering the world of coating production much easier: film lamination.

With this new method, an all-in-one, multi-layer film is laminated to the lens in a fast and easy process – completely replacing the conventional coating processes and consumables.

[…] the film’s stabilizing effect makes lenses up to 18x more impact resistant than FDA standard requirements, allowing labs to grind minus lenses up to 40% thinner (depending on local standards and regulatory requirements), making them lighter as well.

3. Now the lenses are ready for the actual lamination. This happens in the Film-Pod, a compact machine with two process stations. At station one, the Tech-Film is thermoformed to match the shape of the lens back curve which prevents bubbles and wrinkles from forming during lamination. At station two, the film is bonded to the lens for permanent adhesion. Together both steps take just 4–5 minutes per pair.

15 minutes per pair compared to the 3–10 hours processing time for conventional hard and AR coating. Because the Film-Pod laminates Tech-Film AR to the back side of lenses, blanks that are pre-AR coated on the front are used. This is the fastest way to coat a pair of lenses and get them out the door. Later this year, a Film-Pod technology extension will be released for labs that want to use uncoated blanks and laminate both back and front. This will take less than 30 minutes per pair, total for both sides. Still a good cycle time for hard and AR coating that also opens up an additional business opportunity for labs: offering express service at a premium.

Beyond the manufacturing advantages, laminated lenses also provide benefits to the end consumer: the film’s stabilizing effect makes lenses up to 18x more impact resistant than FDA standard requirements,

Blue light Reducing the undesirable effects The wavelength of blue light is at the short end of the range light that is visible to the human eye.

Blue light is more energetic, reaching deeper into the eye and thus endangering the eye more than lowerenergy light. The modern lifestyle means that we are increasingly exposed to it (see MAFO 04/2022, page 15). In this second part of the observations on blue light, the contribution of spectacle lenses to reducing the undesirable effects of blue light is examined. By Fritz Paßmann

The transmission factor is thus the ratio of the outgoing light to the incident light. Antireflection coating (for “increased transmission” or “simple camouflage” in the military) reduces the amount of reflection and thus increases transmission.

coating can be clearly seen. While the super antireflection coating, or better broadband antireflection coating, allows almost no reflection over the entire range of the visible spectrum (orange line), the bluecontrol coating (blue line) has a much poorer antireflection in the short-wave range – which is intentional. However, the residual reflection color is now also intensely blue.

Degree of reflexion

Antireflection coating (for “increased transmission” or “simple camouflage” in the military) reduces the amount of reflection and thus increases transmission.

The measurement report clearly demonstrates that this material is in category 0 of filter lenses. Such lenses are suitable for night driving and signaling. The transmittance in the signal colors red, yellow, green and short-wave blue is over 88%, while the long-wave blue component is blocked by 24%. Together, the lens material and the coatings provide increased contrast due to the stronger scattering of the short-wave light being reduced by reflection and absorption. Demonstration tools

Therefore, in the past, a lens with a yellowish tint, a blue filter, was fitted. However, this did not turn out to be such a good idea, since in time the perception of colors “returned to normal”.

It was in 2006 when Eugenio Casas and his company Insomec Integra Soluciones S.L. developed the first prototype of the “DL80” machine and it was the starting point of our carrer into ophtalmic industry automation. It was the first automatic machine in the world to deblock alloy by hot water inmersion and water jet and to detape ophtalmic lenses by high pressure water jet.

During the period from 2007 to 2010 we kept producing different units and versions similar to the first prototype but innovating each time the deblocking function reaching the point when we used the mechanical deblocking (dry process) keeping the detaping process by high pressure water jet. Special Second DL80 version mention required to those companies that trusted us and supported our innovation and, Having the trust of companies by investing in our machines, let such as Essilor, Signet Armolite, us evolve our products.

This development represents a very special milestone in the history of eyewear optics and will have a major impact in the future," Gunter Schneider proudly summarizes the result of the series of innovations.

Each Modulo ONE machine was presented by experts with in-depth knowledge of their product. Among the highlights of the new launches is CSI Modulo ONE, for example, a system for the automatic detection of cosmetic defects. The optical system screens the surface for irregularities, and characterizes and evaluates them with the help of artificial intelligence.

It detects any common defects such as scratches, pits, center dots, haze,

chatter, cutting marks, spiral and fringes. AWS Modulo is a fully-automated warehousing system for efficient and space saving storage and retrieval. The Modulo Control Center is tailored to the needs of ophthalmic labs. It interacts with the interlinked machines, conveyors, and support systems to capture real-time data on every relevant aspect of the lab. The Automated Dome Loader (ADL) is a fully-automated dome loading system for batch coating that loads, unloads and flips the lenses if both sides of a lens need AR coating. The all in one surfacing center Modulo Center ONE features integrated milling, lathe turning, polishing and laser marking technology. After years of development, the inline coating line was presented as a world premiere at DigiCON. Modulo In-line Coating completes Schneider's Modulo vision. It consists of two parts and automates the backside coating process with cleaning, hardcoating and rapid response coating. The company is particularly proud of this

Maximum flexibility for infrastructure and people The “diverse and flexible – the global community" scenario is the exact opposite of the return to the familiar approach. Flexibility regarding time and space rules and events are no longer bound to one place as digital attendance is easily possible. Worldwide co-operations between venues emerge and multi-site events supported by technology become a mass phenomenon. Smaller venues in city centers, which are not necessarily dedicated event spaces, are favored.

When people attend events in person, they make a very deliberate decision to do so. Meeting others face-to-face is their highest priority then as networking and socializing is very limited in the digital space.

In general, providing purely informative content at both physical and hybrid events decreases while attendees are enabled to make

their own topic-related experiences. New modular workshop formats are developed that can be customized by attendees. As people thus create their own personal event, the degree of participation in the preparation and planning of events is high, which results in innovative concepts.

To enable virtual and in-person attendance, virtual communication platforms and digital tools are integral parts of many events. Hybrid events become standard and to support interaction between physical and virtual attendees, the availability of smart surfaces in venues becomes key. VR/AR technologies are used to support virtual attendance. As attending events is increasingly linked with private trips in order to make the most of travel and justify the effort involved, apps that support getting to know the given destination are on the rise.

“Green and aware – the net zero society” scenario.

In the “green and aware – the net zero society” scenario sustainability is the guiding principle of all actions.

While conventional speaker presentations largely disappear, new formats which integrate the natural environment are in demand, including moving events in the open air. The overall guideline for event formats is to reduce things to the essential. Improvisation and developing innovative solutions together with attendees come to the fore. In fact, event organizers increasingly only provide the platform, without stipulating a fixed program.

Investment in new technologies and digital tools rises, with the aim of creating new solutions for sustainable and ecological resource

Sustainable Processes BUSINESS

Corporate sustainability Measuring progress with KPIs Implementing sustainability in a business successfully requires a sustainability strategy, a definition of clear objectives, and the right mindset. Once concrete actions are taken to implement the strategy measuring results is key to evaluating the outcome, highlighting what has been achieved and adapting the strategy. The effective implementation of sustainability measures needs to be made quantifiable: by using the right Key Performance Indicators. B y Colin Bien

Indicators for sustainability can be categorized into the three dimensions of sustainability (economic, social, ecological). of high interest also to companies who don’t fall under the CSRD,

as shareholders, customers, employees, and other stakeholders are increasingly more interested in understanding the social and environmental aspects of company performance.

Standards and useful frameworks for sustainability controlling There is currently no mandatory framework for sustainability reporting in Europe. However, there are some key figures and facts that are expected in sustainability reporting, like the amount of energy or water used. While the CRSD’s ESG-reporting standard is still in the making, companies can use existing sustainability frameworks to create meaningful sustainability reports. There are many frameworks to choose from, two of which have found wide-spread use: the Global Reporting Initiative’s (GRI) and the German Sustain-

ability Code (Deutscher Nachhaltigkeitskodex, DNK). Both frameworks give a structured overview and provide pre-defined KPIs that make sense of the sustainability impact generated – a helpful guidance particularly for newcomers. However, there are more frameworks available, e.g. the Science Based Targets Initiative

(SBTI), the Greenhouse Gas Protocol (GHG Protocol), or the UN Global Compact.

KPIs for the three dimensions of sustainability Sustainability reporting is divided into three dimensions: ecology, society and economy, or governance. The metrics used in each dimension include both quantitative and qualitative indicators. According to a study, sustainability KPIs in the economic/governance dimension are most often used as many companies seek to save costs while delivering on their sustainability objectives. Consequently, KPIs on profitability gains or yield development are often found used under governance. In the social dimension KPIs on employee retention and training costs are used most often. In the environmental

their effect and effectiveness can be hard to predict. With the help of pre-defined KPIs, a structured and ongoing assessment and amendment is possible. KPIs are therefore a particularly important tool for better decision-making, e.g. if energy consumption goes down slower than planned, the measures can be amplified or additional measures implemented swiftly. Also, cross- or side-effects of measures taken can be corrected early on, reducing risk, cost and ensuring timely adaptation of strategy, and thereby make planning more reliable and effective.

Data collection is a vital part of sustainability management and measurement. To avoid it becoming a time-consuming and potentially costly task, it is advisable to use CSR/ESG management and accounting tools right from the start. There are smart tools available and companies that make an early investment in systems save the time otherwise spent on hand-crafted spreadsheets in which data can get lost or buried.

OUTLOOK

Did you know how much the eyes of tadpoles change when becoming a frog?

Researchers at York University, Canada, and several other institutions explored changes in gene expression in the eyes of leopard frog tadpoles and juvenile frogs using RNA sequencing, allowing them to see the levels of gene expression, or which genes were turned on in the eyes. They also used microspectrophotometry to measure whether the photoreceptor cells in the eyes were more sensitive to the redder or bluer parts of the light spectrum at different life stages. They found 42% of genes in the eyes of tadpoles changed, were differentially expressed, once it metamorphosized into a frog. The genes that control visual function and development, including spectral sensitivity and lens composition, changed the most. The eyes of tadpoles had shifted and adapted to see better in a bluer light environment as they changed to a juvenile leopard frog compared to the redder light environment of the freshwater habitat they live in as tadpoles.

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.

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

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.

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.

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.

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

Fast and highly cost-effective, the robust polisher provides labs with lowest cost per lens!

Highest throughput

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.

CCP Modulo ONE comes with full 4.0 intelligence, smart pad wear monitoring as well as a dedicated cleaning station, cleaning and drying the lens and the block piece.

Fastest cycle times

LCU m dulo

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

CCP Modulo ONE works entirely without tool changes, eliminating the risks that come with it. Running all processes simultaneously, unprecedented speed for highest throughput is promoted.

80

lenses

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.

Better quality, drastically higher throughput, lower complexity – CCP Modulo ONE follows an entirely new philosophy. It comes with a new spindle design, pad architecture and smarter process technology facilitating lights out polishing. Just a single pad is enough to achieve highest quality results. Its innovative pad design provides the versatility and durability required for longterm uninterrupted polishing.
