on’t bother with new lenses; if a patient complains about problems with their vision, just check they are cleaning their teeth properly. This puzzling advice sounds like nonsense, but it seemed to be the message conveyed to the public by journalists reporting on a recent United States study. Researchers at the State University of New York undertook a study of the dental history of 119 patients with glaucoma and 78 people with no history of the disease. They analysed the bacteria in each person’s mouth, as well as looking at the extent of dental work they had had and the oral health routines followed by each patient. Their preliminary findings were that streptococci bacteria were more commonly found in the mouths of glaucoma patients and that people who had undergone more dental work had a higher rate of glaucoma. The findings complement those reported last year in a much larger Florida study. Correlation and causality are two very different things. The US researchers will certainly have understood this, but, sadly, newspaper reporters can be somewhat hastier in jumping to conclusions. Until there is clearer evidence of some plausible associative pathway between the amount of dental work a patient has had and the pressure of fluid in their eyes, the jury remains outon whether these studies are signposting a route for achieving better eye care or whether they are merely noting a coincidental correlation. If the correlation proves to be spurious, it would not be the first: statisticians noted astonishingly close correlations over a ten year period between the divorce rate in the US state of Maine and the per capita consumption of margarine. They noted an equally precise correlation over a decade between the per capita consumption of cheese and the total revenue in the United States generated by skiing facilities. Annual cheese consumption and skiing revenues both also correlate precisely with the number of people in the US who die each year by becoming tangled in their bedsheets (shockingly, this is the apparent cause of death for between 400 and 800 people a year). It seems unlikely that any causal link will ever be found between dairy produce, winter sports and bedsheet mortality. Perhaps the dentistry/ glaucoma link will prove equally elusive.

A supergiant in ophthalmics Y
our reporter has long been one of a seeming minority among commentators on optics to find strange the relative lack of crossover between the two sides of the spectacle industry, frames and lenses. Even the growth and development of the sunglass sector in recent years did not appear materially to change this. Express surprise, and experts from both sides of the divide would frown at you in puzzlement: frames and lenses were two separate, different industries. Why should basic ideas, designs, technologies, marketing campaigns embrace both? Separation was the natural order of things. There were always groups who went against the trend, supporting and co-ordinating lens with frame developments, including Rodenstock and recently Hoya. Now, however, the complementary development concept has received the biggest fillip, probably, that could ever be imagined. Essilor and Luxottica are to combine. Essilor International is buying Luxottica SpA. The resultant holding company will be identified as EssilorLuxottica, operating as Essilor International. The 81 year old Sr Leonardo Del Vecchio (‘Italy’s
richest man’ says a business press report) will be executive chairman and chief executive officer. Essilor CEO Hubert Sagniéres will be executive vicechairman and deputy CEO but will have ‘equal powers’. How fascinating to be a bilingual (Italian and French) fly on the wall at the early meetings of the new group; or better yet, at the meetings of the two teams preparing for those meetings! ‘Global behemoth’ The new group will have combined annual revenues of well over £13 billion and a total market value of £45 billion, with Luxottica contributing slightly more than Essilor. ‘A global behemoth’ says a business press reporter. Is this the ophthalmic supply industry’s biggest corporation ever? In terms of today’s values, taking both Essilor and Luxottica as part of the supply sector rather than retailers the answer is surely yes. Historically, a cursory first review suggests we have here also the industry’s biggest business group ever. Between them Luxottica and Essilor already operate in 150 countries worldwide and have human resources numbering into the 140,000s.
InternationalSCENE One would expect consolidation to represent the first phase of the new ‘Essilor + Luxottica’ relationship. But this, given both firms’ proven past appetites for expansion and growth (and Sr Del Vecchios’ fabled impatience with those he perceives as the over-cautious) may not last long. What will the new Essilor International do next? Is ‘more of the same’, including new retail acquisitions, the early answer? The Essilor + Luxottica combination should give a needed shot in the arm to modern spectacle and sunglass marketing, given the two firms’ different but powerful past activity records in this sphere. If the rest of the industry is astute this should provide worldwide spin-off benefits. Essilor, we are told, already owns nearly 500 prescription laboratories, multiple links of several of the world’s major ophthalmic supply chains, and a growing share of digital ophthalmic retailing. Luxottica has a substantial slice of retail ophthalmics, notably in the world’s leading ophthalmic market, the USA. It has also created and promoted a clutch of high-end, high consumer recognition brands, among them RayBan (as worn by the UK’s Prince Harry) and Oakley. In recent years Essilor has been moving into the increasingly internationalised, increasingly digitalised contact lens world. Growth in any or all of these sectors could accelerate as a result of the new group’s activities. The recent pattern of corporate acquisitions suggests that Latin America could be an increasing focus for EssilorLuxottica. Ophthalmics’ new megagroup might also look at eyecare sectors where, so far, it has made relatively few inroads. The fact that the UK’s savvy Specsavers is opening a series of new ‘Eye Health Clinics’ in its practices indicates a possible direction of travel for Essilor Luxottica, into clinical instrumentation and diagnostics. There are companies in this field that might welcome an approach. Essilor already has five research and development centres spread across the world and a strong reputation in instrumentation albeit, for dispensing rather than diagnostics. What else could follow, these interesting times? Moving ahead on Brexit Fast approaching as this issue goes to press: the March 31 deadline UK Prime Minister Theresa May has set herself to invoke Article 50 of the European Union’s Maastricht Treaty. This is the
never before used mechanism which will trigger the process of the country leaving the EU. Might the deadline be missed? The Government still seems confident that it will not, despite this January’s UK Supreme Court ruling. We at least know a little more now about the UK Government’s aims in the negotiations that will follow the invocation of Article 50. Globalism, it is clear, leads the wish list. ‘A truly global Britain’ is the Prime Minister’s objective, defined in her first major speech. The country was not seeking, she said, any form of EU associate membership – or membership of the single market … though the EU Customs Union which (for example) sets tariff rates might be a case for sectorial exceptions, maybe Associate Membership. Priorities Priorities would include delivering ‘a deal that works’ for the whole of the UK, without promoting EU break-up. The UK would seek to restore control of immigration and to end major annual contributions to the EU budget. A high priority: reciprocity on residency rights for EU expats in Britain, British expats in the EU, and to continue working together across the channel on R&D projects, as well as in security and intelligence matters. ‘We are leaving the EU; we are not leaving Europe’, said Mrs May, adding that it would be sensible to phase in implementation of negotiated agreements to avoid the ‘falling off a cliff edge’ effect business leaders fear. She has promised a White Paper to follow shortly. The UK, Mrs May said, had already registered interest in future trade deals from, among others, Australia, Brazil, China, the Gulf States, India, New Zealand and the USA. Mrs May has met already with new – and very different – US President Donald Trump. His early priorities appear to emphasise re-creation of US manufacturing jobs, opting out of multi-lateral trade deals (‘buy American, hire American’) and – yes – building that border wall on the frontier with Mexico. A meeting with Mrs May covering trade (she has also talked with Turkey’s President Erdogan) and US support for NATO was followed within hours by President Trump banning some Muslim nationalities and all refugees from entering the USA for at least 90 days. Interesting times indeed! W
Essilor in Hong Kong partnership
Essilor has formed a new partnership by taking a 50 per cent stake in Photosynthesis Group, a Hong Kong-based company that markets sunglasses and corrective lenses under a range of banners including MJS. It primarily operates through a network of franchised shopping mall stores in China and has begun expanding abroad in Southeast Asia. The partnership will help to drive faster growth in the Chinese optical industry, while enabling Essilor to broaden its footprint in the promising sunwear segment. Separately, Essilor has also agreed to purchase a 55 per cent equity interest in Jiangsu Creasky Optical, an ophthalmic lens manufacturer and distributor based in Danyang, China. Jiangsu Creasky Optical employs more than 300 people and primarily serves the domestic market. Its acquisition, which is subject to regulatory approval, is designed to expand Essilor's offering in the Chinese mid-range segment. Together, these two partnerships attest to Essilor's strong acquisitions dynamic in 2016, which is expected to result in a scope effect of around 4 per cent for the year.
Safilo licensing agreement for Rag & Bone eyewear collection Safilo Group, the fully integrated Italian eyewear creator, manufacturer and distributor has entered a new license agreement for the design, manufacturing and worldwide distribution of the Rag & Bone collections of sunglasses and optical frames.The agreement will run for five years starting from January 2018 until December 31, 2022. ‘With Rag & Bone we add a directional brand to our growing designer portfolio that benefits from an interesting market shift towards new, trendy and experimental brands. The brand speaks to a very precise target through its distinguishing combination of British understated heritage and modern edgy New York inspired design, and commitment to impeccable craftsmanship from the finest materials. Thanks to our recently established New York based design studio, we are able to capture with precision such new directional design, and cross fertilize it across our worldwide design studio network,’ comments Luisa Delgado, CEO of Safilo. ‘This license thus opens different new business growth opportunities, especially in the US and the UK. It is consistent with our strategy to diversify across segments capturing growth spaces, innovate through trend setting brands, and leverage our leading product and distribution capabilities accordingly.’
Optician helps the less fortunate Eye testing equipment donated by Keeler was recently used by Ruth Easton, an optician from Specsavers in Merthyr Tydfil, on a charitable mission to Uganda. Ruth spent two weeks at the House of Joy charity’s school in the Kasala region running an eye clinic, where she and two friends set up a temporary eye clinic. While there they treated more than 700 people using the Keeler ophthalmoscope and retinoscope set. Almost three hundred pairs of frames — all donated from her local south Wales community — were also given away.

Need we brand lenses? asks Consultant Editor Dick Chaffin
here are famous brands for everything from breakfast cereal to automobiles. Everybody knows Rolls, Mercedes, BMW or Ford. Brands are recognised and well known by the public because of what they are and the many millions of dollars that are spent on advertising. They sell their products by having their brand/name in front of the consumer. It does not matter whether it is ice cream or perfume, products are sold by brand identification. Will ophthalmic lenses be branded? In our industry, lenses do not usually have any visible markings on them. At one time Bausch & Lomb briefly promoted the idea that visible markings could be put on lenses. The idea was really not to promote a particular brand of lens but to advertise or say something about the wearer.
Influence of Luxottica/Essilor merger The lenses could show a college, a place or even a preferred beer. The idea, however, never went anywhere. Now the only markings on lenses are invisible to both the wearer and the viewer. Will the merger of Luxottica and Essilor change 10
things around and sell lenses on the basis of brand? Clearly, Luxotticaâ€™s success has to be based on selling frames with brand names of famous designers. These are brands Luxottica has exclusive rights to for frames. These designersâ€™ names are not famous because they are on spectacle frames, but because they are advertised and sold on other consumer products such as shoes, lingerie, dresses and suits. These brands are known to the public and are sold by Luxottica to the consumer on sunglasses or in optical shops. Brand names on frames can be placed easily on the temples. People will see the names and ask for those brands. Can a designer name be put on a lens? Yes, it can, but not easily and then what would it mean? Can the public recognise or know a particular design of lens by looking at it? Even if a designerâ€™s name were visible on lenses would it be a selling point? Lead set by progressives and photochromics Some might argue that lenses are already branded, particularly in the case of progressive and pho-

tochromic lenses. Essilor, Zeiss, Hoya and others all have names for their lens designs. However, who among spectacle wearers would ask for a lens design such as Autographâ€™, or any other lens by name. There may be some exceptions to this rule. Essilor spent years and years advertising Varilux progressive lenses to the consumer. Is the lens brand Varilux or Essilor, the manufacturerâ€™s name, what sells the product to the consumer? For his part, the consumer can ask for Varilux but he cannot buy it on his own. Transitions has also spent millions of dollars in advertising to the public its photochromic lenses. Transitions may be a brand of photochromic lenses but the person who wants to wear those lenses cannot buy them directly. On-line glasses may be another exception where a brand of lens could be sold directly to a consumer. Also to be considered in the branding of lenses is the difference in the way in which spectacle frames and lenses are sold. Almost universally frames are displayed on a rack or counter or even on a computer screen so that the buyer can try them on. Frames are sold basically on cosmetics. How they look. Although fit is certainly important, the consumer can pick out a frame and then have it fitted. Lenses are sold very differently. There may be choices offered for lenses, but it is unlikely that the purchaser knows what they are or what to ask for by brand. Lenses cannot be tried on before being made into glasses. There are displays and machines that demonstrate various lenses but lenses have to be worn to judge their effectiveness. Role of the dispenser Another complication in branding lenses is the dispenser. In an attempt to brand lenses it is the dispenser who becomes the consumer and not the wearer. The dispenser is the key to the lens sale. He may like a particular lens brand or company for many different reasons unknown to the lens wearer. The dispenser is really a filter in the lens branding process. The dispenser may use a brand of lenses that is available from the laboratory. In that case advertising to the public a lens brand does no good unless the laboratory offers it. Another factor is the groups and chains that own many retail outlets. They determine the 12
lens brands that are made available to their dispensers. Again, examining the proposed Luxottica/ Essilor merger, what does that mean for selling lenses by brand? Luxottica started out as a frame company but has acquired a strong position in optical retailing. Does Essilor want to use that strong retail hold to market its lenses with a brand? From all appearances Essilor does not need Luxotticaâ€™s name to sell lenses, branded or otherwise. Laboratory control Essilor for many years has been following a policy of owning laboratories or creating their own laboratories in all their markets. This strategy has been eminently successful. That means Essilor does not need to advertise to the wearer or the public a particular brand of lenses. A further consideration is the fact that Luxottica and Essilor do not yet own the whole optical market. They may control 30 to 40 per cent of the market but the rest of the market is served by their competitors and are independents. Therefore, to increase their market share Luxottica and Essilor have to try and control more retail outlets. Luxottica might do this by having more frame brands with designer names. Essilor is different. Essilor has to buy lens manufacturers to bring new lens designs or continue to develop them in house. Neither of these strategies will change the branding of lenses. Lenses are a highly technical product. They cannot be sold to the public without the help of professional advice. Even reading glasses over the counter do not advertise a brand of lenses. They benefit from pragmatism. They either work for the wearer or they do not. The reading glass buyer may know a brand name of the company selling the glasses but has no idea of the lens brand. Therefore, there seems to be very little reason to brand lenses to the public in general or even to the glasses-wearing consumer. Educating people about lenses and how they work in eyesight is valuable. But the public still cannot choose a lens and then go out and buy the lens directly. Lenses are calorie free. They do not go from 0 to 60 mph in four seconds and are not the breakfast of champions. These are statements that all belong to well known consumer brands. Lenses are for vision, providing a clear view whatever the brand to the seeing world.
The Global Op cal Revolu on Coping with the challenges Chris Hunt*
n April 1982, for an audience drawn from international captains of optical manufacturing I gave a talk entitled ‘Survival of the Independent Prescription Laboratory’. The event was the 6th international symposium of Manufacturing Optics International. I spoke on the challenges and opportunities which would arise from technologies originating in the computer world and said: ‘in glazing, modern equipment is making it possible to achieve new levels of efficiency. With computer programming for surfacing-instruction already working from the fundamental lens size and shape we cannot be many light years away from computerised edgers in which the glazing former is replaced by an electronic memory.’
Electronic data transfer At the time, laboratories were machine cutting plastic glazing formers via a shape tracer. The more archaic were even cutting aluminium formers with scissors! I remember well, the titters from the audience and the pleasant, but nonetheless, condescending discussions which took place after my talk. My comments were based not on crystal ball gazing, but on the pioneering work I had seen within the international company Pilkington Brothers, my then employers, as part of the new and emerging technology of fibre optics. It was during my association with scientists working in this field that I was first familiarised with the new world of electronic data transfer. No one in my circle of associates had guessed in 1982, that in only another eight years a computer scientist named Tim Berners Lee would have invented the world-wide web and changed the world of data transfer forever. Suddenly, those transmitted lens shapes could travel the world. In the 1990s under my stewardship, Rodenstock UK became the first UK laboratory to offer fully edged lenses, for both rimmed and Supra frames, manufactured from an electronic trace taken in the optical practice or workshop and transmitted electronically. The rest, as the saying goes, is history. In that 1982 talk, I asked the audience five key questions: • How are the consumer’s needs changing and what will be the effect on the profession? • Is the market changing in structure and/or physical distribution methods?
• How are our direct competitors changing? • Who are our emerging potential competitors? • Could the customer become a competitor? Those questions of 30 years ago surely underline why business strategies must always remain the subject of review. The digital revolution which has so dramatically changed almost every aspect of the communication world we live in is still in its infancy in ophthalmics but developing at a rate which few admit and even fewer are dedicating enough resources to address. It is never a pleasant task to look at the shifting sands which sometimes surround pyramids. The digital revolution and free-form At the Autumn 2007 meeting sponsored by OPTICAL WORLD of the Ophthalmic Lens Manufacturers and Distribution Association (a constituent organisation of the Federation of Manufacturing Opticians), I drew parallels between my 1982 electronic glazing predictions and current free-form surfacing. I questioned that semi-finished blanks would continue in their present form and suggested that for superior lens performance both lens surfaces would ultimately be free-formed. This development has not progressed as fast as I first imagined and in my view, free-form technology in terms of its promotion and marketing, has been something of a damp squib. But market developments will, I believe, change this and with the emergence of the 3D printer bring exciting new methods of blank manufacture. I am also surprised that virtual reality technology has not been more engaged by retailers to demonstrate lens performance, coatings and tint absorption effects. Diagnostic technology Consumer needs are most certainly changing and the impact on the structure of the profession is already being felt. An increasing ageing population brings with it greater demand for specialised services in health care, including multiple forms of eye disease. Modern life style is causing an increase in obesity and with it, diabetes and its associated eye problems. Myopia is on the increase; prevalence in Europe is now about 30 per cent, with increasing levels in children. Global figures

He is an honorary life member of the Federation of Manufacturing Opticians and Association of British Dispensing Opticians, Immediate Past President of the Association of Optometrists, Past Chairman of the Optical Confederation and a Past Master of the Worshipful Company of Spectacle Makers.

for myopia are much higher, in some countries approaching three times the European figure. Financial and resource issues in health care provision are putting more emphasis on cost effectiveness in the delivery of services. Here technology, within our industry, can play a pivotal role. The greatest element of eye care costs is in the treatment of disease and the social costs for those affected; early diagnosis is therefore crucial. It is here that the optical manufacturing world can take centre stage. The use of scanning laser ophthalmoscopy and optical coherence tomography is still in its infancy but further development to combine the two, providing 3D imaging, will inevitably progress. Retinal photography is progressively being replaced by more advanced screening methods. Will manufacturers continue to sell this sophisticated equipment to optical practices of all sizes and skill sets (many of which, will struggle with the initial capital investment and update costs) or seek to establish their own networks of diagnostic centres? With digital transfer, the skill needed to interpret the images can be centralised, thus reducing the level of costs at the point of execution by removing the need of a high cost professional to operate the technology, in much the same way, as diabetic screening is being executed now. Every time an eye is screened it provides another image for a data bank that could be anywhere in the world. Technology can compare images with those of a normal healthy retina for an individual of that age/sex/ethnicity and in doing so, flag up abnormalities which will need skilled interpretation and treatment. Change in optometry It is my contention that optometry belongs in this specialist sector and that the eyes of the healthy majority and those requiring specialist knowledge and treatment will become two well defined but quite separate sectors. In consequence, the clinical specialist practitioner will become more clearly separated from the commercial eyewear provider. This will be the result not only of improving the public’s perception of optometry but also driven by the individuals who will elect to up-skill or enter the profession to become clinical specialists. Optometry as we know it today must change. Why? Remote diagnostics, and with this, the challenge to ‘restrictive’ regulatory powers, will impact on the optical world with greater ferocity than most wish to acknowledge. Consumers world-wide are being encouraged to become more health conscious and proactive in their own care. One generation already expects to manage most of their requirements remotely through electronic devices and there is a developing generation which has never known anything else. Technology employing app-based monitoring is already here and as I write this article, the American based company EyeQue has launched its EyeQue Personal Vision Tracker which, for a little under 30 US Dollars will permit ‘the first in-home vision testing solution to combine an optical miniscope, a smartphone application, and secure cloudbased technology platform to form a low-cost, uniquely precise option for people to gather corrective vision measurements whenever and wherever they choose.’ 16
Company promotional material adds that refractive data from the test can be used either as information for one’s eyecare professional or to purchase eyewear on-line. Autorefraction has also reached such levels of accuracy now that almost all the old arguments relating to the risks of using data from it for eyewear provision have worn very thin. Customer, competitor The market is changing in both structure and/or physical distribution methods thanks again to the world-wide web. The need to have physical retail outlets with personal contact with purchasers is being challenged by internet purchasing; the biggest retailer in the world does not own a single store. The high-street distribution channels through which optical manufacturers have always had to reach end users are progressively being pressured by a new form of retailing in which B2C distribution is sitting uncomfortably alongside long- established B2B. Does this mean suppliers and retailers in optics are increasingly going to be competitors? In my view, yes. Some manufacturing companies will have to decide in which camp they fall, whilst the more astute in both camps will realise the benefits of forming strategic alliances. I can even see wisdom in retail and trade associations merging as the interests of high street retailers and manufacturing internet retailers become more closely aligned. It is a big picture out there for those brave enough to address it. One thing is certain, optical manufacturers must not sit back with blinkered or timid indifference and watch internet optical retailing develop through those not associated with the optical sector or its history, who see only global market opportunities. A new consumerism We can already see that internet sales of contact lenses are overriding the clinical codes of individual markets. Whilst practitioners argue that a specification relates to the entirety of the lens including the material, internet suppliers are openly offering product substitution based on the willingness of the consumer to switch for price advantage. It is what some call the paracetamol effect. Yes, overdosing could kill you, but for the majority paracetamol provides a safe, easily obtained, low cost treatment for their specific needs. As consumers are better educated via the internet and other data sources, and increasingly encouraged to take greater control of their own health needs, it will become harder to argue against this type of consumerism. The refractive surgery sector has not, thus far, grabbed as much of the ‘alternative to corrective spectacle’ market as was once predicted, but as implant technology advances and less invasive methods are introduced, it will be assisted both by the growth in myopia at younger ages and an increasing volume of presbyopia. Within this sector I can also see the push for remote diagnostics as standalone businesses. For the industry to believe that this technology driven, consumer demanding market will not radically impact on our sector is to live in cloud cuckoo land. For me, the question is not if but when. The solution (just as it was way back in 1982) is for us to work in greater unity to adopt and adapt to technological advance by embracing it and turning it to advantage for those we serve.
Lens tinting equipment and consumables Peter Wilkinson, OW Technical Consultant The subject of ophthalmic lens tinting is very wide, ranging from the tinting of individual pairs of lenses in a retail environment and in small prescription laboratories right up to large volume tinting of special products including such items as plano sunglass lenses. In a retail environment tinting is usually limited to treating resin or hard coated polycarbonate lenses, but on a larger scale other materials including glass may also require tinting.
he advent of hard and AR coated ophthalmic lenses can raise particular problems both optically and physically. By optical problems we refer to things like how an AR coating affects the relationship between the transmission value and the observed absorption value, and by physical problems we refer to the difficulties of tinting a hard coated lens. There are also some legal and ethical aspects of tinting because a dark tint causes the pupil of the eye to contract, thereby letting excess ultra-violet into the eye so the topic of UV absorption will also be discussed. For large volume tinting there are also problems associated with obtaining consistency. Because of the wide range of topics this article has been divided into three sections. Part 1, dealing with small volume plastic and resin tinting, takes in tinting of resin lenses in small volume; problems associated with hard and AR coating and polycarbonate; UV absorption of plastic and resin lenses; tints for medical and VDU use; and graduated tinting of resin and plastic lenses. Part 2, covering large volume tinting, glass lenses and special products, embraces large volume plastic lens tinting, glass lens tinting, and special products, while Part 3, which completes our survey, dealing with equipment and 18
consumable suppliers, encompasses plastic lens tinting equipment, plastic lens consumables, and glass lens tinting
Part 1: Small volume plasc and resin nng First we will describe how to tint a pair of CR39 resin lenses and later we will talk about the different procedures needed for other materials, AR coated lenses etc. Tinting dye is normally supplied in small bottles which should be shaken first because the dye and solvent tend to separate out. The dye is put into a tank and the bottle rinsed to recover all of the dye. Water is then added and gradually brought up to a temperature of about 150ยบF/65ยบC stirring occasionally. To avoid contaminants it is recommended that pure (deionised) water is used. With the tank lids removed the temperature is then raised to about 200ยบF/95ยบC for the tinting process. If there will be a delay between tinting lenses the lids can be replaced and the temperature lowered. The temperature should be checked with a temperature gauge and the liquid stirred frequently. In an adjoining tank it is suggested that a lens

prep is available which should be used after rinsing and cleaning the lenses. When transferring lenses from the dye to any other tank they should always be rinsed to prevent cross-contamination. How long to leave the lenses in the dye is a matter of experience and obviously depends on the concentration of the dye (which will gradually reduce with usage), the temperature (which can affect colour as well as darkness) as well as the lens material. Not all CR39 lenses have the same absorption rate because the hardness and amount of chemical crosslinking of the molecules varies by manufacturer and lens age. Also some CR39 lenses (for example executive bifocals) are softer because they include a small amount of acrylic to ease the problems of casting a lens with a ridge. These are the reasons why tinting CR39 is considered an art rather than a science. The dye is gradually absorbed into the lens and the further into the lens it goes the less it will fade when washed and wiped and with age due to UV bleaching. Therefore it is always recommended that lenses should be tinted about 10 per cent darker than is required and then bleached back so that the dye near the surface is removed. Water will gradually evaporate from a dye tank and more water will need to be added with time. As the dye is used the concentration will reduce and either more dye must be added or the contents of the dye tank totally replaced. Tinting hard coated CR39, polycarbonate and high index lenses Tinting hard coated CR39 lenses depends very much on the type of hard coat. Some hard coats are even non-tintable but those that are tintable usually do so slower and often produce a slightly different colour. Remember that stock hard coated lenses will have hard coat of both sides but Rx lenses may only have a hard coat on the front surface. All polycarbonate lenses for ophthalmic use must be hard coated because uncoated polycarbonate can be scratched extremely easily. There is a great variation of different types of high index lenses so advice from the manufacturer should be obtained. Not only will the rate 20
of tinting be affected but also the colour obtained. Also, remember that many types of high index lenses cannot accept a high temperature and the surface coating may rapidly craze. Tinting AR coated lenses Because AR coating is virtually always produced in a vacuum by evaporating very thin layers of special chemicals (that are glass-like) they will not allow a tinting dye to be absorbed into the lens. Therefore AR coating should always be done after tinting. This produces a few problems. Firstly the tinting dye can be bleached out of the lens surface by the ultrasonic cleaning that is done before AR coating. The procedure recommended in the previous section to over-tint by about 10 per cenr and then to bleach the dye out of the surface layer is certainly essential and if this is done then the amount of tint left in an AR coated lens will be similar to that in a non-AR coated lens. However, this only means that the colour absorption value will remain the same, not the transmission value as will be explained below. The diagrams on the next page give the values of absorption, transmission and surface reflection from a lens surface without an AR coating. The surface reflection is directly related to the refractive index of the material and this is 4 per cent per surface for CR39. For higher index lenses the surface reflection value is higher and the reflection figure given will need to be modified. Note that double internal reflections etc means that these values are not absolutely precise but give a very good idea of what is happening. In the following examples it can be seen that a ‘clear’ CR39 lens with no absorption tint has a 92 per cent transmission value rather than the 100 per cent value that is often assumed. In a lens with 30 per cent absorption the transmission value is actually approximately 63 per cent. Because the human eye/brain perceives absorption (rather than transmission) it often assumes that a ‘clear’ lens has a 100 per cent transmission which is certainly wrong. When ordering tinted lenses the method of specifying tints varies. In most countries opticians would often incorrectly request an LTF (lens transmission value) of 100 for an untinted lens and
a 70 per cent LTF for the tinted lens shown below. In some other countries (e.g., Germany) it is the absorption which is specified so for an untinted lens they would specify zero absorption and for the other tinted example shown they would specify 30 per cent absorption. Whichever method is used is not important, it is the communication between optician and manufacturing laboratory that matters. For lenses that do have an AR coating the situation is much simpler. Let us assume that the AR coating is perfect and that there is no reflection.
It can be seen that the absorption value does not change when the lens has an AR coating so the method of specifying absorption is very easy to understand. If LTF is specified then it is important that the optician and the manufacturing laboratory understand each other. Other tints including UV and for safety reasons In addition to â€˜plainâ€™ tints, graduated and rainbow tints are sometimes specified. To produce these a graduated tinting device is needed. Very W
simply it just dips the lens in and out of the dye so that a dark tint is obtained at one edge of the lens and a pale (or no tint) is obtained at the other edge. Obviously the lens must be inserted into the dye upside down to obtain a graduated tint that is darker at the bottom of the lens when worn. Specific colours can be specified for VDU use and for medical reasons and these often include the blocking ultra-violet light. However there are some very good practical and legal reasons for including an ultra-violet blocker. It must be remembered that the pupil of the eye can vary in size and enlarges when the light level is low. This is not usually seen on humans but the size variation of catâ€™s eyes is well known. The problem is that when the pupil of the eye enlarges it lets in a much larger amount of ultraviolet light which may in extreme circumstances damage the eye. Therefore the darker a tint in a lens the more important is UV blocking. All sunglass lenses obviously incorporate UV blocking. (Sunglass lenses made of glass rather than plastic potentially have a problem because glass does not normally absorb UV light.) With plastic lenses it is very easy to include a UV absorber by a tinting process, which should be done before adding the tint colour. There are International Standards for the amount of UV that must be blocked in tinted lenses with different levels of darkness. However, these rules are rather complicated and the author takes the attitude that adding close to 100 per cent UV absorption is so simple that this might as well be done for any tinted lens. In fact there is no reason why lenses without any tint should not have a UV absorber and this is very common in countries like Australia where bright sunlight is very common. All CR39 lenses do include a very small amount of UV blocker to minimise deterioration of the chemical links inside the CR39 but this is not sufficient for full eye protection. This raises the question of how far into the visible spectrum the UV needs to be blocked, because there is no exact dividing line but a gradual merging from UV to visible light. The generally accepted dividing line is that UV light stops at 400nm and then blue light extends to about 500 nm. There are conflicting opinions 22
about whether blue light can cause damage to the eyes. Certainly the blue light very close to where the ultraviolet starts at 400nm wavelength may be a potential problem. The region from 380nm to 400nm is just on the limit of human visibility and if it is blocked then a clear lens would appear to have a slight yellow tint. Other regions of the spectrum, such as infra-red can be blocked by tints but these are special situations that should be investigated only if necessary.
Part 2: Large volume nng, glass lenses and special products
Most of the readers of OPTICAL WORLD will not be involved in large volume tinting or in glass lens tinting so these subjects will only be covered briefly. Large volume tinting is carried out by sunglass manufacturers and the priority is to obtain precise consistency. To do this, special measures are taken, including using only plano lenses that have been cast in bulk in ways that provide uniform tinting dye absorption. Also by using special low concentration dyes the tinting time may be extended to typically 24 hours and done in large baths where the temperature is very accurately maintained and the liquids are circulated and filtered continuously. The UV absorption required for the safety of sunglass lenses is provided by adding UV absorber to the CR39 monomer when casting the lenses rather than adding it after casting. Glass lens tinting This was obviously very common many years ago (before the introduction of CR39) and until about 30 years ago most of the larger Rx laboratories had glass lens tinting units. There were also some subcontract glass tinting companies that provided a service to the smaller Rx laboratories. The process was relatively simple (and rather similar to AR coating) where the lenses were placed in a vacuum chamber and coloured chemicals were evaporated onto the back surface of the lens. To prevent distracting reflections an AR coating was often applied to the front of the lens in the same way.
