CCU m dulo 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.

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.

Non-stop uninterrupted blocking for highest throughput, at lowest cost per lens.

Agility Autodeblocker from Coburn Agility Autodeblocker is a completely waterless, automated deblocking system. Developed for large labs seeking speed and efficiency, Agility is the fastest automated deblocking system on the market, capable of deblocking 240 lenses per hour. Agility is ideal for high volume labs that prefer a convenient automated solution. Both lenses are automatically removed from a job tray, placed onto the appropriate deblocking rings, and deblocked simultaneously using a mechanical action. Contrary to deblocking with water jets that displace alloy, cause alloy waste, and produce contaminated water waste, Agility separates the lens from the block in one clean, swift, mechanical action. When combining Agility with the Duality De-Taper & Cleaner and Velocity Lens Coater, customers can fully automate the post-polishing process.

Lenses are deblocked, de-taped, cleaned and coated in minutes without operator involvement.

Labs can also integrate the Integrity Alloy Recovery System for automated alloy recovery, which is completely waterless as well. Visit www.coburntechnologies.com

What is hazardous waste?

RCRA defines hazardous waste as a solid waste. It can be any garbage, refuse, sludge from a waste treatment plant, or air pollution control facility and other discarded material, including solid, liquid, semisolid, or contained gaseous material resulting from industrial, commercial, mining, and agricultural operations, and from community activities.

▶ Produces less than 2.2 lbs of acutely hazardous waste/month. ▶ No storage time limit if the total waste stored is under 2200 lbs (about five drums).

▶ Must ensure that hazardous waste is delivered to a person or a facility that is authorized to properly manage its disposal.

The journey from PAL to NAL Natural Accomodation Lens (NAL) There is a new multifocal lens. It is a lens that requires a gentle raising or lowering of the chin to facilitate distance, intermediate, and near vision. But unlike progressive addition lenses (PAL), there are no narrow corridors to contend with, and no fitting height measurement is required, the inventors proudly report. This new multifocal lens technology is called NAL, which stands for Natural Accommodation Lens.

The dream wish list It is more than 60 years since the introduction of PAL. With new knowledge and technological evolution in computer technology and advancements in software development tools, we have reached the point that our dream wish list can be realized.

First, we must drop our self-imposed limitations, get out of the box, and start our quest armed with new knowledge, unaffected insight, creativity, commitment, and courage. And the dream wish list? Actually, it is not that far-fetched or long, thanks to the numerous PAL advance-

NAL and its impact on the industry and the patient Despite the enduring efforts of lens designers worldwide, the bell curve of new PAL concept design innovations is significantly leveling off.

There have been over 60 years of PAL design improvements and design modifications. Seiko, Zeiss and Rodenstock pioneered custom back lens optimization over 20 years ago. Since the digital freeform revolution, more than 200 "proprietary" or patented designs have been introduced.

New PAL innovation at this time appears to be trying to squeeze water from the stone.

The consequence that comes as no surprise is considerable disorientation among the global ECP community regarding the actual and objective visual performance of the abundance of PAL design offerings.

Most understand that today`s freeform digital technology is more about branding and marketing. Most commonly, it is “good”, “better”

TECHNOLOGY

History of Progressive Addition Lenses – PAL The first patent for a progressive lens was British Patent 15,735, granted to Owen Aves with a 1907 priority date. Unlike modern progressive lenses, it consisted of a conical back surface and a cylindrical front with opposing axes to create a power progression. Keeping that in mind – although Owen Aves` design was never commercialized – Essilor cannot technically be considered the creator of the first progressive lens. In 1948 Bernard Maitenaz followed in his father`s and grandfather`s footsteps and joined Société des Lunetiers as a research engineer. On March 2, 1951, Bernard Maitenaz deposited an envelope at the National Institute of Industrial Property in France, which included four drawings and mechanical data that would make it possible to manufacture the modern-day progressive lens. On November 25, 1953, Essel submitted the first patent for his invention. The first commercially viable progressive lens in Europe, Essel`s Varilux, was introduced in 1959. In 1965 the Univis Omnifocal was introduced in the United States. The first progressive lenses were made of glass. In 1972 Essel changed its name to Essilor because of the fusion of two companies, Essel and Silor. In 1976 the first organic progressive lens, Essilor`s version of Columbia Resin 39 (CR39) index 1.50, the Varilux Orma, was released. A physicist Werner Koeppen and his team worked on the development of the Varilux Comfort from 1960 into the 1990s, and Varilux became the most successful PAL. Over half a century has passed since the introduction of the PAL, and the world has not been the same.

The PAL evolution and its current state The advancements in equipment, technology, and software mathematical and development tools have opened the doors to amazing new conceptual and design possibilities − the freeform revolution! First, it was OptoTech`s founder Roland Mandler, who, in 1985, adapted aerospace industry computer numerical control (CNC) technology in the production of ophthalmic lenses. Then, in 1986, Gunter Schneider of Schneider started using CNC technology in precision optics production, which later evolved into ophthalmic lens production. However, the biggest game-changer in PAL evolution came with the development of PAL Freeform Lens Design Software. On October 11, 1977, Japanese scientists Hiroyuki Mukalyama and Kazutoshi Kato filed a patent application for a progressive multifocal lens and manufacturing method. The US 6,019,470 patent was granted on February 1, 2000, and was assigned to Seiko Epson Corporation. On July 18, 2000, the USPTO granted a patent for a spectacle lens with a spherical front side and multifocal back side and process for its production, US6089713A, to Albrecht Hof and Aldabert Hanssen. They then assigned it to Carl Zeiss Vision GmbH. Both patents followed the conventional PAL concept, but instead of utilizing a semifinished lens with the progressive design cast or molded on the front side of the lens, the multifocal surface was created on the back of a rotationally symmetrical front of a semifinished donor lens blank. In addition to the PAL design on the back side of the lens, the final lens back surface was further modified with Individual Optimization. Over the past twenty-plus years, that concept and production technology radically improved multifocal lenses` visual performance and acceptance/adaptability.

PFAS forever?

Long lasting chemicals – restrictions, chances and challenges For some, they are “forever chemicals” that should never be released into the environment; for others, they are necessary substances for the production of everyday consumer products or medical devices, for instance contact lenses. We are talking about per- and polyfluoroalkyl substances – in short PFAS. At first glance, two interests seem incompatible: on the one hand to save the environment and human health and on the other hand to satisfy consumer desires and to not restricting an entire industry. But one authority has now created facts. By Hanna Diewald

In early February 2023, the European Chemicals Agency ECHA published a ban proposal on all PFAS. It is a message with huge implications.

A choice for the environment and human health but at the same time, the industry faces huge challenges and stakeholders are lobbying for exemptions – at least for longer transition periods. But why is the topic so hotly debated?

Broadest restriction in history According to the latest estimates, this group of substances comprises more than 10,000 different substances. It is the broadest restriction proposal in history and many different industries are affected.

Among those industries that work with PFAS on a daily basis is also the ophthalmic industry. This is because PFAS are used in spectacle lens coatings as well as in contact lenses.

this persistence, as long as PFAS continue to be released to the environment, humans and other species will be exposed to ever greater concentrations. Even if all releases of PFAS would cease tomorrow, they would continue to be present in the environment, and humans, for generations to come”.

PFAS tend to pollute groundwater and drinking water. Certain PFAS are known to accumulate in people, animals and plants and cause toxic effects. Certain PFAS are toxic for reproduction and can harm the development of foetuses. Several PFAS may cause cancer in humans.

Some PFAS are also suspected of interfering with the human endocrine (hormonal) system.

According to ECHA the expected mean PFAS tonnage in the European Economic Area (EEA) is 49 million tonnes, leading to emissions of about 4.5 million tonnes during the manufacture and use phase when no action is taken. The overall annual health costs following from exposure to PFAS in Europe has been estimated in a Nordic Council report from 2019 to be between €52 and €84 billion.

Argumentation The proposal states that: “Different regulatory risk management options have been considered, e.g. CLH and authorisation, but these options follow a substance by substance approach. In contrast, a restriction offers the possibility to define a broad chemical scope, thereby avoiding The European Chemicals Agency (ECHA) describes PFAS as follows:

Analyzing in detail the reason for this lack of use[3], these are the relevant statements from the study:

MAFO 3-23

!AZ.ind

Ophthalmic Optics in Numbers SPOTLIGHT

▶ 11% of users do not use PALs[2] because of the price associated with them. ▶ 23% of users show concern about the difficulty of adapting to progressives.

▶ 33% are not very clear about how they work. ▶ 33% do not use them for other reasons, including wanting to wait to start using progressives.

All of this highlights the need on the part of ECPs to have educational sales tools that help them introduce presbyopes to the world of progressive lenses and thus improve the visual quality and life of these patients.

In this sense, Horizons Optical has presented this February during Mido tradeshow mimesys coach, a virtual simulator that allows the patient to experience the use of progressive lenses and appreciate the advantages of this type of lens, thus becoming a key element in the purchasing decision. ◆

[2] PAL: Progressive addition lens [3] 2022. HO internal survey performed on n=126 users in Europe in 5 countries.

Reasons why users do not were PALs.

From ECPs perspective, the study confirms that:

▶ They have 1.5 non-adaptations from new PAL users[2] per month. ▶ Progressive lenses are the third cause of non-adaptation. The centering of the lens is critical.

▶ Many patients do not fully understand what a progressive lens Ivette Bruguera

consists of and have high expectations.

Experts agree that progressive lenses are the best solution for almost all presbyope patients as the lenses offer better vision at all distances.

However, data obtained confirms that there are misconceptions inherent to the progressive lenses that keeps a large group of presbyopes reluctant to start using this type of lens.

Ivette Bruguera is a Product Manager at Horizons Optical. With a degree in Optics and Optometry from the Polytechnic University of Catalonia and a master's degree in project management from the Management School of Madrid. She spent over four years as the lead of EMEA technical support, where she gained valuable experience in visual solutions.

Setting priorities Targeted and always one after another You know the problem that the tasks grow over your head and you have the feeling that you are doing lots of things, but there is no land in sight. In order not to sink in the sea of many challenges, there is only one option: you have to set priorities. In doing so, you need to keep your goals in mind and incorporate them into a time management system. But self-discipline is also indispensable. By Hartmut Fischer

Time and expertise When you set priorities, it doesn't just mean setting a timeline.

You also have to determine which employee has the necessary competence to solve the task delegated to him or her. If the employee is not able to complete the requirements placed on him or her in the desired time, it is not only your priority plan that will fail.

It can quickly happen that the employee – who is otherwise so important for the company – is demotivated by the perceived "failure" and thus slackens altogether.

During a process, the basis on which the prioritization was made may change. For longer-term processes, you should therefore check at regular intervals whether the basis on which you set the priorities has changed and whether an adjustment of your prioritization is necessary.

Goal oriented The priorities of a task are always based on the set goal. It is therefore important that you describe this goal in as much detail as possible. In most cases, the individual tasks that you need to prioritize already follow from this description.

At the top of the list are the tasks that play the biggest role in achieving the goals. If prerequisites are necessary for this that still have to be created, these naturally have priority. Often, one particularly important aspect is not sufficiently illuminated: feasibility. If it only becomes apparent during the ongoing process that the tasks are not feasible or represent too high a risk for operations, a lot of time and effort has been invested without the goal being achieved.

This results in unnecessary costs that could have been avoided with a realistic implementation check.

Daily routine organized quickly The first prioritization is the daily agenda. Here are the various tasks that need to be done independently, that are evaluated and timed. If possible, put all tasks to the test. Especially the daily recurring activities are often done "automatically" without evaluating them according to their importance or necessity.

For the evaluation of the daily routines one often uses the "ABC method".

This involves determining what you will do yourself immediately (priority A), what can be done later or delegated (priority B) and what will definitely be delegated (priority C). Proceed according to the following scheme.

that are "nice to have". That is why the first question in determining financial viability is whether there is an economic necessity. The long-term perspective must also be considered.

Whether the boom for individual products or brands will continue in the next few years is an open question in the medium to long term.

However, the fact that service will play an increasingly important role in the future – not least as a result of internet trading – is almost certain.

Investments in staff training and development are likely to have a more positive impact on sales.

Step 2: Financial feasibility Once you have decided on a project, you need to check whether it can be financed. In particular, when you need to borrow outside capital,

OUTLOOK

Did you know that researchers use 3D ­bioprinting to create eye tissue?

Scientists use patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases. The research team from the National Eye Institute (NEI), part of the National Institutes of Health (NIH), printed a combination of cells that form the outer blood-retina barrier – an eye tissue that supports the retina's light-sensing photoreceptors. The technique provides a theoretically unlimited supply of patient-derived tissue to study degenerative retinal diseases such as age-­related macular degeneration (AMD).

The research was published in the journal Nature Methods DOI: 10.1038/s41592-022-01701-1
