he prevailing wisdom is that differences in take‐up for eyecare is a direct function of wealth: the less well off suffer from more sight disorders and uncorrected eye defects than the wealthy simply because they cannot afford the cost of treatment. This may seem self evident, but it turns out that it is actually only part of the story. Recently published research at the University of Michigan in the United States has revealed wide differences in diagnosis, treatment and outcomes among children, even where all had the benefit of health insurance that should have covered the direct costs. The study examined health insurance claims between 2001 and 2014 for nearly 900,000 children. In this substantial study, researchers analysed the data, tracking claims among children from families with different income levels. They tracked how often children from different family income groups visited ophthalmologists and optometrists, and they focused particularly on the diagnosis and treatment rates for amblyopia and strabismus. They picked these conditions because it is especially important that these are identified and treated by the age of 10 in order to avoid the risk of permanent vision impairment. The study revealed striking differences between income groups. Children from families in the lowest income group had 16 per cent fewer eye tests than those from middle‐income families. Children from families with the highest income recorded 19 per cent more eye examinations than those from middle‐ income families. The frequency of eye tests also affected the number of amblyopia and strabismus cases picked up; with researchers reaching the conclusion that there were 12,800 missed cases of strabismus and 5,400 missed cases of amblyopia. Given that all of the children in the study benefitted from health insurance, researchers concluded that the differences must be due to factors other than the direct cost of eye tests or treatment. They surmise that less affluent parents may have more difficulty taking time off work or may face transport challenges getting their children to an optometrist, a problem compounded by there being fewer eye care providers in less affluent areas. Whatever the cause, the message from this important study is clear: our industry has very much more to do to educate and inform parents of the need to have their children’s eyes tested at an early age and to look out for conditions that can be readily treated if picked up soon enough.

Essilor and the Cottets

G

erard Cottet (pictured above), who died aged 84 this summer, was one of a remarkable group who helped shape the international destiny of French lens giant Essilor, and hence of world ophthalmics in the late twentieth century. His father, Raymond Cottet, came of a family with a strong eyewear industry background in the Jura region of south-eastern France (still a renowned ‘District of Optics’). Reported to have been an active ‘Resistance man’ during the Nazi occupation of France, he headed the major London operation for Société des Lunetiers (Essel) before becoming a member of the board team which rebuilt and developed Essel in the difficult post war years. His son Gerard thus spent part of his formative years in London. Essel had long been a major ophthalmic goods exporter, including to the USA, with which London had strong links. Ray Cottet was a natural internationalist, whose excellent English (he was followed in this by his son!) helped him realise and appreciate the value of Anglophone markets in the lens industry future. Some early planning meetings took place in the central London offices of the Optician magazine, then shared with the Federation of Manufacturing Opticians. M. Cottet was also a key supporter of the 1966 London optical trade fair which marked the launch of OPTICAL WORLD’s predecessor journal, Manufacturing Optics International, MOI. Back in Paris with his family, Gerard Cottet gained experience in banking and with a leading advertising 2

agency upon graduating from business school in 1956. When he joined Essilor in 1961 he worked first in advertising and marketing. In 1962 he in his turn became based in London, where his marketing training — and his good English — helped him achieve a successful launch of Essilor's brand new Varilux lens, even on the conservative British scene. Back in France, in 1972 Gerard Cottet was instrumental in arranging the marriage between Essilor and former rival Silor (Sociéte Industrielle de Lunetterie) from which Essilor was born. The same year he was appointed sales director. Varilux inventor Over the next two decades, this new and fast-growing entity was led as chief executive officer by another of Essilor’s remarkable men, Bernard Maitenaz, the inventor of Varilux. (How M. Maitenaz brought this truly ground-breaking lens concept to fruition in the days before any but the most primitive style of computer still baffles the optical observer.) Essilor’s fortunes were increasingly built on the foundations of the growing Varilux lens family. Before the advent of free-form, the progressive lens (or varifocal, a holdover in British usage from the time of Gerard Cottet's launch) was the transformative factor in the French and increasingly all western markets, as demographics favoured retail uptake of this truly ‘progressive’ lens category.


InternationalSCENE Gerard Cottet followed Bernard Maitenaz as Essilor’s CEO on the latter's retirement in 1991. Thanks, in part no doubt, to his Anglophone and Anglophile background, he already knew the US market well. In the early 1990s he spearheaded Essilor of America's drive into the prescription and wholesale laboratory sector. Notable achievements here included the acquisition of Gentex, who built on the trend to organic materials to introduce ophthalmic grade polycarbonate. Was M. Cottet in the audience at that memorable industry meeting where a Gentex presenter fired a real bullet at a sheet of the material? The writer still remembers the impact! Gerard Cottet's long-sighted ability to foresee the future of lens markets also helped determine Essilor International’s decision to co-invest with PPG Industries of America in founding organic photochromics producer Transitions, now world leader in this lucrative sector and under Essilor's sole control. He retired from the company in 1996, after 35 years' service. He was succeeded as CEO by Xavier Fontanet. Another Essilor acquisition The giant Gerard Cottet helped to grow has gone on growing in the 21st century. One of more than 10 new additions to the ever-enlarging portfolio, but not the first to demonstrate company awareness of online's significance, is Vision Direct. Bought for a rumoured £120 million from a group of institutional investors, this firm ruffled retail and industry feathers when launched by a student entrepreneur in the UK in 2004 (as Glasses Direct) to sell spectacles to consumers. Latterly, Vision Direct has been notching up £57 million's worth of international sales: sunglasses and contact lenses too. Its structure, we are told, will remain unaltered under the new owners. Protecting against indoor visual dangers Essilor’s Protect System lenses, incorporating Crizal antiUV coating, were launched this Olympic summer. This innovation, though, emphasised eye-harm possibilities emanating from indoor, artificial light sources (especially LEDs) as much as from outdoor light. The system promises reduction of ‘harmful’ blue-violet light impact on the eye from molecules incorporated within the lens material to absorb the relevant wavelength: a similar principle to Transitions photochromics? Lenses are ‘aesthetically clear’ with no yellowing. Essilor offer it, with Crizal Prevencia anti-UV coating on the rear lens surface, across their Varilux VS and VE lens ranges. Hoya have introduced a specifically outdoor-orientated Sportive prescription range of wrap lenses (6 or 8 base). Also new from Hoya: special sphere tints in 1.5 to 1.56 index materials and a wide minus/plus power range. One Olympics-related frame product: German specialist

natural materials producer Woodone launched a range in the colours of the German national flag. Germany was consistently among the top ten medal winners at the Olympics. Oh, and by the way, it’s comforting to know that if in your excitement you dropped your Lacoste L8165 sunglasses from Marcolin in Brazil’s Lagoa it would have floated. Sports eyewear is reckoned to account for three to seven per cent of the retail ophthalmic market in developed countries such as Germany, depending on whether you measure by volume or value. The extent to which an Olympics or Paralympics benefits growth in this sector may be most readily measured by a company like MEI, whose global growth has been based in part on its ability accurately to finish high-curve sports lenses. From the perspective even of a successful UK medacampaign (the UK finished second only to the USA in the table) it must be said that retail ophthalmics appears to have done relatively little to raise consumer awareness of sports eyewear’s potential to enhance performance, eye comfort or eye safety. Perhaps, in the UK this lack of enthusiasm has been partly due to a thorough slapping down by the Advertising Standards Authority over the ‘harmful blue light’ controversy. India continues to advance With growth in gross domestic product claimed at over seven per cent, consistently outstripping China, India with its democratic structure, 1.25 billion population and fast-growing, well educated middle class is now a perennially interesting target for Western business, especially since Dr Narendra Modi's Bharatiya Janata Party came to power in 2014. One holdback factor, however, has been this vast country's exceedingly complex, clogged-up and costly bureaucracy - a legacy of the British Raj. India is divided regionally into some 20 states, with urban regions, almost city states, to add to the mix. Each has its own taxes and regulations to add to those federally imposed. ‘India is less integrated economically than the EU’ says a think-tank spokesman despairingly. The system also makes it slow, cumbersome and expensive to move goods around, as each state operates its own border checkpoints. A proposal to replace all this with one centralised Goods and Services Tax could, say commentators, cut the Gordian knot and substantially enhance India’s GDP growth rate. It has been approved in principle and should come into force in April 2017. But will it? Ratification by at least half the states is needed first. And some commentators feel the early departure into academia of widely respected Reserve Bank Governor Raghuram Rajan is not a good omen.

Zeiss mark founder’s 200th birthday Carl Zeiss was born in Weimar, Germany, on September 11, 1816 and this year sees the 200th anniversary of his birth. In honour of the company’s founding father, Dr. Wolfgang Wimmer, head of the Zeiss corporate archives, along with historian Stephan Paetrow, conducted research into the life of Zeiss in order to write a new biography to mark the occasion. ‘Relatively little is known about Zeiss’ life’, states Dr. Wolfgang Wimmer. In order to complete the biography, along with other available resources, the archivist and hisCarl Zeiss

torian gleaned new insights from an old ledger, in which Zeiss kept detailed records of

income and expenditure relating to his company and family between 1848 and 1863. Available now from Amazon.com, the Carl Zeiss biography is the latest publication to depict the life of one of optics’ most innovative and inspirational men. In addition to the biography, Zeiss are conducting a range of events and activities to celebrate the founder’s 200th birthday, along with ‘Carl Zeiss Day’ held on September 11, in Jena, Germany.

Nidek’s answer to volume retail edging One of the fastest wet cut edgers in the world, the Nidek SE-9090, has re-invented itself from the mass production laboratories into high volume retail facilities and Birmingham Optical are celebrating its success following the 70th installation onto the high street. For over 15 years the Nidek SE-9090 high speed edger has sat proud in almost all large glazing production facilities throughout the UK and is now making a huge impact in retail opticians who have in-store glazing. Now with the 70th retail store installation, the SE-9090 has created the perfect glazing solution and is resulting in many positive outcomes on the high street. ‘To say we’re happy would be a massive understatement’, says Robert Lofting, Specsavers director at Hastings. ‘The new Nidek SE-9090 is unreal. It’s made such a massive improvement to an already efficient lab. In its first month it clocked up around 8,000 lenses and could do so many more’. As one of the most versatile edgers on the market, the SE-9090 can be used in conjunction with various Nidek automated systems, allowing it to grow with the user’s business.

Branding ophthalmic lenses Consultant Editor Richard Chaffin o brand has several meanings from burning with a hot stick or iron to designate ownership or a name for a particular company or product. Brands of all kinds of products are common phenomena in our society. Everybody is familiar with famous brands of goods or products. In such things as automobiles, Rolls Royce and Mercedes are famous names or brands. In perfumes, Chanel No. 5 is a leading brand recognised the world over. In the supermarket, the shelves are filled with well-known brands to be picked out by consumers. These products have been advertised extensively to the consumer by brand name and product type. A company may use its own name or create a brand name for its products. Tea, coffee, chocolate may all be sold under one brand name that may or may not be the manufacturer’s or the company’s name.

T

Frames and designer names In the optical business, brands are different. In the frame industry you have companies such as Luxottica and Safilo. Their brands are really not their company names but the designer names they feature whose brands are contracted for by the frame companies because they are well known and heavily advertised to the public. They come from other industries, fashion dresses, suits, shoes or other products. A consumer can come in off the street ask for a brand name product, and buy it. A glasses wearer can select a frame by brand name and purchase it. They will find the designer or

brand name embossed on the frame and in addition a brand logo on the temples. However, the optical consumer cannot buy a brand without the help of an optical professional. They still need the help or advice of a dispenser to purchase eyewear in an optical shop or even on line. Sunglasses and brands Sunglasses are an exception to brands for glasses. Sunglasses are advertised directly to the public by brand identity. Anybody can shop for the brand of sunglasses they want. Purchasing sunglasses does not need the advice of a professional. The consumer can decide on his or her own. There are many brands to choose from such as Oakley, Maui Jim, Ray Ban, Costa Del Mar or countless others. The lenses come with the sunglasses as a complete package. Sunglass brands are advertised directly to the consumer and can be bought in a department store, sports shop or other retail outlet. Sunglasses, whether or not they have a designer name and logo, will have a brand name. Lens brands are different Lenses are a very different product so far as brands are concerned. Essilor, Zeiss, Hoya, and many other companies manufacture ophthalmic lenses. However, lenses are not branded in a way that can be recognised by consumers. They have to be told by the dispenser what brand of lenses they are wearing. Consumers are privy to very little information on lens brands. Lenses are not generally advertised W

to the consumer. There are a couple of exceptions that provide examples of brands in lenses being promoted directly to the public. Varilux is the number one example of a lens brand that is advertised directly to the consumer. It started out as a unique new lens, a progressive. Essilor originally advertised Varilux with the hope of creating a demand for a new design of lens. Varilux has been on the market for over 50 years and is no longer unique. Transitions is another lens product that has been advertised extensively to spectacle wearers. It was originally presented as a competitive product to glass photochromic lenses; taking advantage of the worldwide movement to plastic lenses, Transitions let the consumer know there was a brand of photochromic plastic lenses available. They encouraged wearers to ask the dispenser for their lenses. Transitions, owned jointly by PPG (51per cent) and Essilor used public media, TV, magazines, etc to capture the plastic photochromic market. Dispensers and brands Glasses are not really a consumer product/brand. To be more specific they are a professional prophylactic product. Wearers need the 3’Os to buy their eyewear. That is of prime importance in the purchase of lenses. Lenses require an understanding of optics, technology, sociology, and physical anatomy. These are all concepts the regular wearer may not be familiar with or does not care to master. Therefore most glasses are made to be fitted and sold by a professionally trained optician/dispenser. It is the dispenser that has to be influenced and sold on promoting a particular brand. A consumer may ask about a brand of progressive lens or photochromic lens but it is the dispenser who knows what he or she has to sell and what is most appropriate for their patient. The dispenser filter Brands are a consumer-marketing concept. In the case of lenses it is the dispenser that is really the consumer. He is the purchaser of a brand and has to be sold on the idea and the product. This can be referred to as the ‘dispenser filter’. How then can Essilor, Zeiss, Hoya and others place their brands of lenses in the hands of the dispenser and on the faces of wearers? One way to do this is through the influence of a laboratory that supplies the dispenser. 10

www.optical-world.co.uk

Some time ago Essilor started on this strategy, recognising that they could best promote their lens brands by owning laboratories. In the United States, Essilor may control as much as 45 per cent of the lenses dispensed. Essilor has also followed the same strategy internationally, buying laboratories or starting laboratories in the UK, Canada, Germany, and elsewhere. More recently Zeiss and Hoya have also followed to some extent the same strategy. Is lens branding a success? How successful are brands for lenses in view of the ‘dispenser filter’? That question is hard to determine. Essilor, not satisfied with buying laboratories only, has gone on to buy competitive lens manufacturers. Letting these competitive lens manufacturers continue to market their own brands in competition with Essilor brands is another strategy to control the market. Zeiss, a well-known brand of its own in lenses, has added Sola lenses to its family of brands. Zeiss is recognised the world over for its optical expertise, but as a lens brand it has a long way to go to catch up with Essilor. Hoya has followed a slightly different policy. It has advertised directly to the ‘independent’ dispenser its competitive brands in progressive lenses and now in photochromic lenses. Dispenser factors and brands Dispensers of lenses have many factors impacting their choice of lens brands making it difficult for the lens manufacturers and even the laboratories to influence them. Factors that the consumer does not necessarily know about or have any control over. Quality of a brand, availability of a brand, customer success with a brand and profitability of a lens brand are all factors for a dispenser. Ophthalmic lens brands therefore are very different from the well-known brands that are part of everyday life. Although women may buy sunglasses with a brand/designer name it is highly unlikely they will include a brand of lenses. The dispenser has hundreds of brands of progressive lenses to choose from. They also have new brands of single vision lenses and blue blocker lenses but the wearer probably will have no idea of the brand of their lenses, which is why brands in the optical world are very different.


Higher Index Photochromics Tony Jarratt, Technical Editor One of the most dramatic changes to occur in the ophthalmic industry in the last few decades has been the introduction of ‘variable’ tints,the depth of which depends on the ambient visible radiation. Identified under the generic name of ‘photochromic’, the technology has spawned a large range of material variations and tints, although one, Transitions, is used by the vast majority of the industry as their preferred process. The use of these photochromic materials has radically reduced the need for solid tints, i.e., a tint produced within the lens material during manufacture. It has also reduced the demand for resin lenses with a fixed tint.

efore the advent of photochromic materials, lenses could only be supplied with a ‘fixed’ tint, to a set transmission level. Users had to choose the depth of tint required, before the lenses were supplied – either using mineral glass substrates (‘built in’ tint) or organic (CR39) where the tint is introduced by immersion in a dye bath. This can pose a problem, because the depth of tint chosen is not always the best for all requirements. A dark sunglass lens, with say a 15 per cent transmission (LTF), could be perfect on a bright sunny day, but could be almost useless on a cloudy day. In addition, the use of solid tints built into mineral lens materials causes problems with high-powered prescriptions: the thicker the lens, the greater the absorption of the transmitted light. Therefore, as the lens thickness varies, the depth of tint will also vary. A minus lens which is thicker at the edges will exhibit an increase in tint towards the lens edge. This colour variation can become quite marked with very high powers, leading to a ‘polo mint’ effect – almost no colour in the centre but a very dark peripheral band of colour. Positive powered lenses will be affected in the reverse manner, with dark central areas, making it virtually impossible to use darker tints for high power lenses. Not only does this difference in colour density produce a lens with a very poor cosmetic appearance, it can also cause visual problems for the wearer. The high myope can still experience glare problems, due to the very pale central portion of the lens and a high hyperope may find the lens too dark to be able to obtain any

useful vision, particularly when trying to read in low light conditions. These problems do not occur with tinted resin materials (CR39), as the dye is taken up within a fixed depth of the material, leading to an even tint, independent of the lens thickness. However, the user is still faced with the problem of a tint which might not be appropriate for the prevailing conditions. With some prescriptions, particularly those with very high cylinder powers, which result in marked thickness difference between the main meridians, the problems can still be experienced to a small degree when using photochromic materials. The reason for this is due to the composition of the lens material and the way in which it darkens. However, for all ‘normal’ prescriptions the tint density will be virtually uniform over the entire lens. Without delving into the chemistry of the material, it is sufficient to say that the ‘variable’ properties of glass photochromic materials are introduced through the use of silver compounds – in the form of silver halides. It is well known that silver darkens (tarnishes) when exposed to the atmosphere and light, and this property was first used in the production of photographic film emulsions. (The effect was first noticed in the 18th century, when it was discovered that silver in the presence of nitric acid, can be darkened by light). This darkening effect on silver, which is caused by the presence of visible light and ultra violet radiation, has thus been used to produce photochromic materials. In


production, the silver halides are ‘locked’ into the lens material and thus remain in ‘suspension’within the glass matrix. If the glass material is exposed to light, the silver compounds darken, but unlike photographic emulsions, the colour fades again, when the light source is removed. This light / darkening / light cycling can take place almost indefinitely, without the material suffering any noticeable fatigue. This reversible effect does lessen with time, but the photochromic properties of most materials now on offer will last the period between the purchase of new spectaclesn i.e., it will last longer than the average time between eye tests and lens change. Darkening process As the darkening of the lens material is caused by the action of the light, the degree to which this takes place will depend on how far the radiation penetrates the lens. As the energy enters the lens material, it will cause the silver chemicals to change colour and darken, thus absorbing some of the radiation. Consequently, its effect on the inner layers of the lens material will be reduced and this reduction in effect will cause a smaller change in the colour of the inner strata of the lens material. This means that the major darkening effect will take place relatively near the lens surface, thus reducing any effect of increased lens thickness caused by high spherical prescriptions or large cylindrical powers – unless these are quite marked. The process works very well for glass but was, originally, not so successful when used for plastic materials. The chemistry has been far more difficult to unravel and it has taken chemists and material manufacturers many years to come up with suitable formulae for producing plastic photochromic lenses, which are commercially viable. The early attempts only managed to produce materials with a limited life and darkening range and with a very narrow spectral filter range, i.e., they would attenuate certain wavelengths but not others, producing unwanted colour effects in the lens when in the darkened or darkening state. To produce a lens with an even spectral absorption, i.e., the absorption is the same or almost equal for all wavelengths, has been easier in glass / silver combinations than it has for plastic materials. However, as can be seen by the numbers of resin photochromic lenses currently available, this problem has now been fully overcome. When producing a photochromic material, the manufacturer has to take into account two major require-

ments, these being the amount to which the lens will darken and then fade (back to its original ‘colour’ / depth of tint), and the speed at which the process takes place. The amount to which the lens darkens will affect the use to which it can be put, i.e., to provide a good sunspectacle lens, the material will have to darken to at least 35 per cent LTF and should really be darker than this for the majority of users. Most photochromic materials will have a slight residual tint, even when in the fully lightened state. This will be in the region of 85 to 95 per cent transmission, which will allow comfortable indoor vision for most purposes. They will then darken to differing degrees, depending on their composition. Many will change to about 25 to 30 per cent transmission, whilst a few will go as dark as 8 per cent LTF. The speed at which a photochromic material darkens and then fades is also important. The first materials to come on the market were very slow, when compared with today's products. On the other hand, a lens, which changed colour too fast, could be disconcerting and even dangerous. For instance, driving with a lens which changed colour almost instantaneously could disorientate the driver with possible calamitous results. An eye takes several minutes to fully adjust to changes in lighting conditions and a lens, which takes a similar time to darken, is the ideal match. The rate of change should be fast enough for the wearer to notice the change, but not too fast. The rate at which the lens bleaches, or fades, is also important. A user coming into a darker interior of a building does not want to wait too long for the lens to fade back to a comfortable state. Any lens should be able to fade back to about 60 – 70 per cent transmission within a few minutes and should be at about 85 per cent in approximately 15 to 20 minutes or less. Temperature and radiation dependence There are two complicating factors, which affect the amount of darkening. These are the type of radiation incident on the lens and the ambient temperature. The majority of the darkening effect is due to the presence of ultra violet, rather than visible light, and there is a marked difference due to temperature. Heat produces a bleaching effect on photochromic materials and hot climates therefore tend to reduce the darkening effect of the lenses. Unfortunately, hot bright climates are a very good reason for wearing tinted lenses, but whilst the ambient light will darken the lens, the heat will tend to counteract this effect.

However, manufacturers have managed, over the last few years, to reduce the temperature dependence of photochromic materials and heat now has a far lower effect than it once did. Conversely, photochromic lenses taken to a high altitude, where the ultra violet levels will be high and the temperature low actually produce better photochromic effects. This ultra violet factor also makes a fully darkened photochromic lens a good UV absorber – although this will not be always be quite as good as a CR39 lens with UV inhibitor (this is not necessarily true for the latest photochromics now available, which provide 100 per cent UVA and UVB absorption). At these higher altitudes, the lens will also take longer to fade, due to the lower temperature. Mineral / organic materials As already mentioned all the earlier lenses were produced in glass, with silver halides as the photochromic agent. Over the years, they have proved to be very successful. However, with the ever-increasing use of plastic lens materials, particularly in the USA, where safety considerations are paramount, a great deal of effort has been put into producing a lighter and safer alternative. However, the first plastic photochromics to reach the market were distinctly unsuccessful. They often had a blue tinge when exposed; the rate of change in colour was slow and only reached a moderate depth of tint. The material life was also limited, with colour fatigue becoming apparent after only a few months’ wear, compared with the almost unlimited life of glass photochromics. The latest materials and processes are far more successful and for all practical purposes now have characteristics which match those of glass. These have good darkening rates and excellent absorption figures. They are available in single vision, bifocal and progressive lens types, allowing the laboratory and dispenser a wide range of choice. Methods of manufacture A major difference between glass and photochromic lens materials is in the method of manufacture. As already mentioned for glass, the darkening agents, silver halides, are introduced into the glass melt and are distributed throughout the lens blank. Until recently, this type of production has not worked for plastic materials. For plastic photochromics, there are several methods of introducing the agent, including coating and surface

14

penetration or imbibing. Products such as Transitions use imbibing (see below), which can be likened to the surface dyeing of CR39 lenses. In the process, the photochromic material is allowed to penetrate the lens surface to a depth of some 0.15mm, being controlled very accurately. It is the uniformity of this penetration which will control the final performance of the lens. This ‘surface layer’ effect, will produce high-powered minus and plus lenses, which exhibit an even tint, even when exposed to high light levels. The ‘polo mint’ effect, sometimes found in glass photochromics will also not be so noticeable on the latest ‘solid’ resin photochromics. This is mainly due to the absorption of UV in the outer layers, which in turn reduces the effect this radiation has on the inner core of the lens. Any depth of tint variation due to thickness difference in the lens is virtually eliminated. One other difference between the materials is the fact that glass photochromics will tend to stay darker as they age, whilst plastic materials tend to lighten somewhat. However, this ‘lightening’ effect found with the plastic lenses is reasonably slow, so the lenses will normally be suitable for use longer than the usual interval between sight tests. This ageing effect makes the replacement of one lens to a pair of spectacles difficult. As the lenses will be of different ages, they will not necessarily darken to the same degree or at the same speed. In addition to normal glass and resin lenses, there are also some other variations on the market. An example of these is glass-bonded lenses where a photochromic layer is bonded to a base lens of either 1.523 crown glass, or higher index (for example Zeiss). This allows the supplier to supply specialised lenses and high power Rx without the problems associated with thickness difference. The following text has been kindly supplied by Transitions: Transitions Optical use a patented Imbibition process for most standard index lenses. In the Imbibition process photochromic dye is applied to the front surface of the lens and then processed in a way that causes it to penetrate into the lens material. In addition to Imbibition, Transitions Optical also utilise Trans-Bonding and Trans-Polarizing. The TransBonding process made it possible to offer photochromic technology in desirable high-index, ultra high-index, Trivex and polycarbonate materials. Trans-Polarizing refers to Transitions Optical’s proprietary manufacturing processes which enable the processing of Transitions Vantage lenses with variable polarisation.


Hard and AR coating Virtually all the lens materials currently available are suitable for AR coating and in the case of resin lenses, hard coating as well. CEN regulations With the introduction of CEN regulations relating to

tinted ophthalmic lenses, five classes have been defined and are applicable to all tinted, photochromic and sun lenses. For each class of transmission, a corresponding minimum level of UV protection is required. The wearer must be informed as to which lens class the lenses belong and the corresponding conditions of use that apply.

Summary of expected requirements for a photochromic nt The very basis of a photochromic product is that it should be able to change its depth of tint under the influence of various light/UV levels. Whilst doing this it needs to meet a number of requirements. According to intended use, the tint should reach a certain level of absorption. Whilst changing depth of tint, the colour should remain as constant as possible. For use indoors, i.e., in its light state, the tint should be as neutral as possible. When intended to supply a ‘sunglass tint’ the absorption level should remain reasonably dark, even in the ‘faded’ state. The tint in the dark state should be ‘even’ across the entire lens surface and the speed of darkening should (for most purposes) be as fast as possible. The speed of fading back to the ‘light’ state should also be reasonably rapid, while the darkening and fading rates and the level of darkening should vary as little as possible for differing temperature levels.

The photochromic materials should be capable of accep ng a hard and/or AR coa ng. The lens should provide good UV protec on and the depth of nt should not preclude its use when driving. Most of the currently available photochromics meet these requirements. Index When the first photochromics were introduced they were only available in 1.523 index mineral material, followed a few years later by 1.498 (1.5) CR39. Over the years, as higher resin indices have been introduced, photochromic nts have gradually become available in each successive higher index. They are now available in all indices from 1.5 through to 1.74. In addi on Zeiss s ll list their ‘compound’ lens, where a 1.523 photochromic shell is bonded to a 1.7 carrier lens and Norville offer three similar lenses in 1.7, 1.8 and 1.9. This ar cle does not cover indices below 1.53. The indices covered range from Trivex/Trilogy at 1.53, through to 1.74. Tables 3 4 and 5 show the availability of the various indices. Transitions www.transitions.com Transi ons Op cal is an independent company, formed in 1990 in the USA by PPG Industries, one of the largest American chemical companies, and Essilor Interna onal, for the produc on of resin photochromic lenses. They pioneered the successful introduc on of ‘imbibed’ photochromic materials and are now world leaders in their manufacture. This process involves the ‘transfer’ of the requisite dye to the lens surface, rather than dip dyeing, as is the case for standard resin lens n ng. Using this method, the company can exert greater control over the finished product. (A dic onary defini on of ‘imbibe’ is ‘to absorb or cause to absorb, liquid or moisture; assimilate or saturate.’) The full process involves the use of modified polymers, which are used by lens casters to produce finished un- nted lenses. These are sent to one of the Transi ons produc on sites for imbibing and then hard coa ng. The finished lenses, now with full photochromic proper es, are then sent back to the lens caster for edging in the normal way. The following is the company’s defini on: Photochromic technology has been a core competency at Transi ons Op cal for more than 25 years. The defini on of photochromics is a light-induced, reversible change in colour. A photochromic lens contains millions of photochromic molecules. In the colourless state, these molecules consist of two smaller chromophores (or halves) held out of plane from one another (at different angles). Or, in other words, when the lenses are clear, the two halves of the photochromic molecule are perpendicular to each other. When exposed to light energy, a chemical bond breaks and the molecule rearranges itself from two smaller

16

www.optical-world.co.uk

chromophores into one large chromophore (or one flat plane) that absorbs in both the UV and the visible poron of the electromagne c (EM) light spectrum. This means the molecule now has colour. Simply put, the UV light changes the shape of the photochromic molecules and the lenses darken. When the light energy is taken away, heat reforms the bond, and the lenses go back to clear. Because the fade back reacon is driven by heat, when it is very hot outside the photochromic molecules are pushed back to their clear state even as UV light energy is driving them to ac vate. This is why the performance of all photochromic lenses is influenced by temperature. To overcome this challenge, Transi ons XTRAc ve lenses use a different formula on of photochromic dyes. Transi ons XTRAc ve lenses feature a broad spectrum dye specially designed to react to both UV and visible light for extra darkness outdoors, even in the car. These special molecules collect ‘extra’ energy enabling the lens to darken more, even in the ho est climates. Table 2 shows the various characteris cs of the current Transi ons nts. As with all photochromic technology, Transi ons XTRAc ve lenses are influenced by temperature. This is because heat reforms the chemical bond of photochromic molecules—hot temperatures drive the lenses back to clear; and the colder the temperature, the darker the lenses will get. This temperature factor has been minimised in Transi ons XTRAc ve lenses. The visible light ac va on allows the lenses to become even darker in both average temperatures and in hot temperatures than tradi onal photochromic lenses. Life360 data shows that Transi ons XTRAc ve lenses in both grey and brown are darker than Transi ons Signature VII lenses. Hoya www.hoya.com Hoya use Transi ons and their own Sensity material. This la er material is excep onally clear indoors and turns quickly into a dark intense colour outdoors. It is available in grey, brown and emerald green.

and fading up to 2x faster. By combining these molecules with Zeiss lenses, it has been possible to design a new genera on of powerful self- n ng lenses – PhotoFusion. These lenses adapt to changing light fast,darkening in 15-30 seconds and fading back to 70 per cent in 5-10 minutes.
