ith each year, Halloween seems to have taken on increasing importance as a ‘festival’ to be celebrated. Thanks to the influence of movies and television, the United States ‘trick or treat’ tradition has spread, to the point where it has supplanted some of the equivalent traditions in other cultures. In the United Kingdom, for example, children used to collect ‘a penny for the Guy’ to buy fireworks to commemorate the 17th Century Gunpowder Plot to blow up Parliament. Now, as private use of fireworks has steadily fallen out of favour, British children have all but abandoned Guy Fawkes and plumped instead for dressing up in ghoulish garb and collecting Halloween goodies. What raises concerns among ophthalmologists is the length that teens and young adults will go to as part of their Halloween costumes. If you are dressing up and donning make‐up to look like a zombie, it is hard to resist the temptation to top the outfit off with a pair of zombie cosmetic contact lenses. In most jurisdictions, the cosmetic contact lens market remains unregulated. That means revellers risk infection, eye disease and eye damage through careless use of decorative lenses, especially when swapping them at parties or lending them to friends to try. Every year, around the world, opticians issue their warnings, and every year these fall on deaf ears; not as a result of Halloween ear prosthetics but because these are warnings of risks that seem remote to youngsters with an innate sense of invulnerability and only out for a fun night in fancy dress. The solution is not to try to scare those out for a fright night but to increase the pressure on regulators to apply the same stringent safeguards to cosmetic contact lenses as those applied to corrective lenses. Canada is doing just that. This has been the last Halloween in which cosmetic lenses could be sold in Canada without strict regulation. From next July, cosmetic contact lenses in Canada will be subject to the same licensing, manufacturing and labelling regulations as corrective lenses. It is a ‘trick or treat’ example that other national governments need to follow.

InternationalSCENE

Placing greater emphasis on eyecare techniques two-day ‘National OCT conference’ organised by Topcon in Birmingham, near the Optrafair showground last month, underlined the strong current UK ophthalmic market trend to greater emphasis on clinical eyecare techniques. This meeting for optometrists was designed to enhance the value of eyecare in every sense for end-consumers and practitioners, with presentations on ‘How OCT works for my business’ matching others on, for example, ‘Clinical Benefits’, ‘Glaucoma diagnosis’ and ‘OCT in diabetes’. A worthwhile initiative? Yes, surely. However, as a writer noted in a recent issue of OPTICAL WORLD, human experience suggests that something has always got to give: in this case, that more emphasis on eyecare is liable to mean a waning of emphasis on eyewear, more specifically on that aspect of eyewear where professional knowledge is crucial: lenses. This time, can the professionals focus more on ‘the new eyecare’ without losing the lens focus which is so important for both end-consumer and professional wellbeing? To judge from comments published of UK consumers, this area already calls for greater rather than less attention by optical practitioners. Spectacle lens potential is at more than a little risk of under-apprecia-

tion and misunderstanding in a price-driven Anglo Saxon market like that of the UK.

Campaigning Essilor Thankfully, Essilor UK – one of the few lens industry names some, (though not all) consumers recognise has been taking action this autumn to redress the balance. The vehicle for this exercise: Crizal UV lens treatment. Introduced by way of a high-circulation broadsheet newspaper in the UK (the Daily Telegraph), bolstered by social media action and a new dedicated, reportedly well visited page on the firm’s website, the central theme of a sustained autumn advertorial campaign has been the human eye’s need for year round protection from invisible, insidiously damaging ultraviolet radiation. In the UK, this is not an easy theme. It has entailed the introduction of a relatively unfamiliar concept as well as a complex product. After lengthy exposure, consumers have largely accepted the ‘sun harms skin’ message put out by industry; a multi-million pound market for protective creams and lotions is based on it now. But UV and the eyes? Despite valiant efforts by the European Sunglass Association (now joined at the hip with


InternationalSCENE the US Vision Council) even health and fashion journalists here still seem ill-informed. One comment noted earlier this year: ‘Now polarising lenses are available, surely we can take sunglass lens quality for granted and simply focus on sunny frames’. The Crizal message is more complex still: this is a product that offers eye protection not only in tinted form, but for clear lenses as well. It is not a wholly new message; Corning France, for example, attempted to get it across with a UV-shielding clear glass back in the 1980s, but gained limited success, not only in the UK but in some of Europe’s more lens-savvy markets. Have times changed enough? This is certainly a message with which Essilor deserves to succeed, adding in the themes of Crizal's capacity to reduce discomfort from glare ‘when working at a computer, watching TV or driving at night’. This ground was covered in Essilor’s initial Telegraph feature. authored by Tim Adler with input from the firm’s own Andy Hepworth (well known and respected by UK opticians). Interestingly, a follow-up also by Tim Adler focused on ‘the superior level of service offered by an independent optician’, with advice on lens choices such as Crizal forming one aspect of that service; UK independents, according to analysts GfK, now account for only some 20 per cent by volume of the UK retail ophthalmic market. ‘People don't mind paying more once they understand the benefits that premium lenses can provide’, commented this writer. A further ‘advertorial’, in one of the paper’s weekly magazines, compared the choice of a premium spectacle lens like Crizal with clothes or accessory purchases (a new suede jacket, or pair of shoes maybe), suggesting the level of investment to be considered. Again the applicability of Crizal to clear lenses was stressed, with Transitions (now of course, fully integrated with Essilor) as a flexible-tint prescription sunglass alternative. More features have followed (for example) from the perspectives of a long distance lorry driver and an IT manager, with differing Crizal benefits highlit. Whether Essilor customers or not, practitioners in the UK (independents especially!) owe this firm a debt of gratitude. Unfortunately, one flight of swallows does not make a summer. It can take five or more to be recognised, let alone acted on. Essilor UK surely has ongoing plans; meantime who else in the supply industry, or in ophthalmic retail, will now pick up the premium lens baton?

Eye surgery in the spotlight Crizal is not the only ophthalmic product to have been accorded consumer press attention this autumn. Alternative approaches to the treatment of age-related macular degeneration, ‘the most common cause of blindness in the developed world’ have also generated a mix of editorial and advertising headlines. In the UK the London Eye Hospital has been promoting its iolAMD ‘adaptive optics’ implant, said to be suitable for use in all forms of AMD using straightforward cataract-style surgery. Also in London, Moorfields Eye Hospital meanwhile has trialled the use of embryomic stem cells grown on to form a retinal transplant ‘patch’ implanted in the eye of a patient with ‘wet’ AMD. If encouraging early results are followed by sustained improvement, the procedure ‘could be in routine use within three to five years’. The role of anti-blue light lenses to ward off AMD was the theme of recent advertising by third ranked national ophthalmic retail chain Boots Opticians. Complaints (whose?) have however been upheld by Britain’s Advertising Standards Authority.

Migration and the EU The biggest, saddest story east of the Atlantic this autumn has been the never-receding floodtide of refugees trekking painfully across Europe, mainly to the economic haven of Germany. With a population in decline, that country for a time offered an unreserved welcome … though reservations crept in after the first half million arrivals. Not likely to have been rejoicing at the prospect, Germany’s 8,000 optical practitioners; almost all the migrants (one million and more from Syria alone) were non-spectacle-wearing young men. Coming from wartorn Syria, admittedly, most have probably had other preoccupations to contend with than their next eye test, even if President Bashir al-Assad is qualified as an ophthalmologist! Almost equally saddening: the European Union’s breakdown in unity, not to mention strategic planning and co-ordination, in face of this greatest human movement through and across its borders since the last world war. How struggling Greece has been economically affected by the hundreds of thousands crossing its borders no one seems to have reported. And who can say whether a British exit from the ‘Union’ of Europe is more or less likely. This will be based on a national referendum possibly as early as next year. Uncertainty is all around, as 2015 closes.

Seeing the Light Consultant Editor Dick Chaffin examines the important relationship of light to the way we see

L

ight is ‘what makes vision possible’, as defined by Webster’s Dictionary. But not all light is the same and the light the human eye perceives has changed dramatically. Even the light radiated by the sun has changed. In earlier times daylight and moonlight provided all the natural light and there was nothing else. Fire changed that and man learned to use ‘artificial’ light. The light of the fire, the light of the oil lamps, the light of the candles, and the light of many other things that burned were the source of vision. These sources of light are all different, as different as today’s sources of light, incandescent, fluorescent, LED, Xeon, and more. The character of light has moved with technology from the simple fire’s flame to the powerful laser’s arc. So who cares; and what difference does it make?

What is light?

Light is energy. Visible light is generally considered to start at the blue end of the colour spectrum (400 wavelength) and end at the red (750 wavelength). There are also extensions of light at the blue end with ultraviolet light and at the red end with infrared. Infrared light and glasses are used by the military for night vision.

Visible light is made up of various wavelengths of the different colours from blue to red. As a matter of fact there has been on going controversy over what colour light (wavelength) should be used for determining index of refraction. Light energy can be dangerous, an over abundance or brightness can be damaging to the human eye. Snow blindness is an example. Laser light energy and UV light are powerful and can be used medically for cutting and burning. UVA and UVB light from the sun, wavelengths less than 400 or 420, are considered dangerous and are recommended to be blocked in spectacle lenses.

Ophthalmic lenses

Lenses, prosthesis, are the device that transmits the light into the eye that allows for vision. Lenses are important. They change the light, focus it and filter it. Lenses are the first line of defence as light enters the eye. There is light that will harm the eye, light that is too powerful for the eye to see. However, not all light that reaches the eye through lenses or without lenses has dramatic immediate consequences. The light or light energy from computer screens is a source of industry attention.

There are multiple solutions put forward to avoid fatigue, tired, or strained eyes from computer use. How much of these conditions are due to the type of light given off by the computer is uncertain. This is only one example of one type of light in question. Lenses are made of different materials with different features, coatings or treatments. Each of these elements changes the characteristics of the light that is passed through the lenses into the eye and then what is seen. Lenses must be transparent to see. However, there are degrees of transparency, how much light lenses let through. Not all lenses or lens materials, considered clear or ‘white’, let the same amount of light through to the eye. Although these may be small differences they may have an effect on vision. Another factor to be considered in different lens materials is the Abbe value. The breakdown of the light into its different wavelengths or colours. Abbe values of lenses for some people can be an important element in how well they see. Index of refraction is another characteristic of lenses that shifts the way light passes into the eye. Higher or lower indices that vary with the type of lens material and are a measure of how fast light travels through air can make a difference in physical properties, weight and thickness. There are two major types of lens treatments that change light. The two treatments are polarisation and photochromic. They each perform a function that changes the light seen. In the case of polarisation it only applies to sunlight.

Polarisation

Polarisation filters reflected light. It does not filter direct sunlight except to the extent of colour in the polarising film or treatment. Lenses that are polarised let light through on a directional basis. Polarised lenses are always mounted in glasses on the horizontal or 180 degree axis. That means they are intended to filter the light reflected off a flat horizontal surface. Among other things, this allows seeing down into the water when sunlight reflects off of it. Polarisation is not well understood by the profession. The key factor is reflected light and the way in which the polarised lens is mounted. That limits its usefulness to daylight or special purposes. The process of polarisation uses iodized crystals that are lined up directionally. The iodized crystals do affect the light other than polarising it and give a sharpness of colour. Photochromic means light sensitive. Photchromic

14

www.optical-world.co.uk

lenses both change light and use it for that purpose. What that means is light energy passing through a lens changes its filtering characteristics from light to dark. There are different methods for this reaction to take place depending on the type of lens material. However, all processes for ophthalmic lenses, no matter what material, use energy from light to make them photochromic. Discovered more than 75 years ago in a Corning Glass laboratory, glass photochromic lenses use silver halide crystals in a glass matrix that swap an electron in the presence of UV energy and darken. In plastic lens materials it is a chemical process that takes place and is reversible but is still activated by UV light energy. In the case of both glass and plastic lens materials the photochromic properties of the lenses are sensitive to temperature factors. Cold temperatures darken lenses over a greater range. Photochromic lenses filter (control) the light transmission. They may not get quite as clear as white lenses and can get as dark as good sunglasses. Photochromic lenses will also filter specific light characteristics in accordance with the colour, turning grey, brown or other.

What about coatings?

Anti-reflective coatings and hard coatings are the major types available. Hard coat does not change light in most cases. However anti-reflection coating does change the light characteristics as seen through the lens. AR coatings should match the index of the lens material for the greatest effectiveness. However, this is not always the case because of the varieties of lens materials in use. AR’s purpose is to eliminate the light that is reflected off the surface of the lens. This has two results. One result is more light goes through the lens and the other, the lens becomes less visible to an observer. Coatings can also block certain wavelength of light such as blue blockers. Everybody should care. Vision is generally thought of as one of our most important senses. Some of the light we see has been considered the cause of vision loss – cataracts, macular degeneration and other medical conditions. These potential causes of blindness may be a build up of damage to the eye over long periods of time. Therefore it is prudent to be aware of the light we see and the changes modern technology has brought about in light as well as the changes in the natural world and the physiology of the eye. Light has travelled all the way from the ‘Big Bang’ to what we see in the optical world today.

High Index Single Vision Plastic Lenses Tony Jarratt, Technical Editor

rom the patient’s point of view, probably the most important factors governing the choice of lenses (apart from price) are the cosmetic appearance and wearing comfort of the finished product. Both of these factors are dependent on the material used for the lens production and can be sub-divided into – weight, thickness and curvature. Weight affects the comfort of the finished spectacles and thickness and curvature, the appearance of the lenses. A thinner, lighter lens will be more comfortable to wear and will have a better cosmetic appearance than a thicker and usually more steeply curved one. There are other factors which affect the suitability of the materials used, but these won’t necessarily be obvious to the intended user. These are constringence, transparency, durability, strength and the ability to accept a tint or durable coating – both anti-scratch and anti-reflection. All of these factors must be considered when choosing a lens for each patient. The best way of keeping the thickness and curvature to a minimum is to use a higher index, but these higher index materials do have some disadvantages. Some have a greater density and are therefore heavier, volume for volume. In addition, as the index rises so does the chromatic dispersion. Finally, many of these materials are more difficult to coat and tint. However, the growth of substrates with these higher indices proves their popularity 16

www.optical-world.co.uk

and advances in manufacturing techniques are gradually making production easier as time passes. The latest plastic materials to be introduced, which offer reductions in weight, have been in the high and very-high index ranges (over 1.64) and these will be considered in this article. It is these materials that offer the best answer to weight and thickness reduction. The original plastic materials, acrylic and CR39, provided substantial weight savings over glass substrates. However, their low refractive index meant that they were thicker and exhibited greater curvature. The other materials gradually introduced, polycarbonate, mid-index resin and more recently Trivex, all have relatively 'low' indices and therefore are still thicker and show greater curvature. It has taken the introduction of 1.67 and 1.74 materials for plastic materials to really compete with the higher index glass materials in the production of thinner lenses. There is even one 1.76 material on the market , produced and cast by Tokai. Indices currently available Table 1 shows the indices most widely available in both glass and plastic materials. As can be seen, glass still provides the two highest indices, although resin materials are now almost up to that level, with the Tokai 1.76 index. The table also shows the Abbe number and density (g/cm³) for the ma-


terials. The figures for the index are ‘rounded-off’, as manufacturers quote slightly different values for what are essentially the same materials. This is due to the different wavelengths of the light used in determining the index (e line and d line).

and polycarbonate. The factors that determine the final weight of a finished lens are effective diameter, surface geometry (both of which control the finished volume) and density of the material.

Table 1: Indices most widely available in glass and plastic (indices reviewed highlighted in red)

Density of the material and weight Thickness and curvature The density of a material is Table 2: Sag comparison with CR39 n=1.498 (indices reviewed are highlighted in red) a value which specifies the mass of the material per unit of volume. It is normally expressed in grams per cubic centimetre (g/cm³). The density of the various materials shows that the ‘lightest’ in g/cm³ is 1.53 (Trivex) and the ‘heaviest’ 1.9 glass. In fact glass material is 3.6 times as heavy for a similar volume of material.

These ‘calculations’ don’t take into account of the probable differences due to centre or edge thickness variations - but they give an indication of the thickness savings to be expected by using a different index. Apart from using a higher index to reduce thickness, we can also use aspheric surfaces to further flatten the curves. This is particularly effective in flattening plus lenses where the centre thickness is reduced and the lens appears flatter, thus improving the cosmetic appearance. The effect, although less, can still be useful when producing minus lenses. By selecting the smallest available diameter, either from stock or by careful surfacing, the thickness can also be reduced for plus lenses. Abbe number and chromatic aberration (constringence) Generally speaking the higher the refractive index the greater the chromatic aberration produced by the material (indicated by a lower Abbe number). This means that the higher indices can be expected to produce more colour fringes around high contrast objects. The ‘normal’ index materials with Abbe numbers in the range 58 and 59, and the mid-index materials with numbers around 40, exhibit no discernible colour fringes, as far as the wearer is concerned. However, the higher index substrates with values in the low to mid 30’s do show these chromatic aberrations, particularly in higher power lenses. First time users will probably notice this effect, but most become accustomed to it after a period of wear and will then usually tolerate the lenses quite satisfactorily. Coating for durability and strength The material used must be durable and have a resistance to breakage. Most plastic lens materials are ‘soft’ when compared to glass and are, therefore, more easily scratched. To overcome this they must, almost without exception, be protected by a hard or scratch-resistant coating. This means that the materials must have the ability to accept a coating and retain it during use over a reasonable period of time. However, the main problem with coating durability is the difference in expansion / flexing of the substrate and the coating itself. The first hard coatings introduced onto the market were too hard and could not flex as

18

www.optical-world.co.uk

easily as the substrate – causing crazing and cracking, especially when subjected to heat. Over the years the chemists have been able to almost eliminate this problem and modern coatings are ‘hard’ enough to provide protection, whilst 'soft' enough to flex with the substrate. The refractive index of the coating layers(s) must be matched to the index of the underlying substrate otherwise colour fringes (similar to Newton’s rings) will be produced at the junction of the lens and base coating. This means that several different monomers will be required to cover the coating requirements of a range of lenses. A further consideration is the application of an anti-reflection coating, which means that the hard-coating material will need to be capable of accepting a further coating layer, with good wearing properties. Composition The higher indices have been possible due to the addition of sulphur into the material, with greater quantities producing a higher index. These materials allow the thinnest lenses to be produced; they do, however, have some problems – they are more sensitive to heat, easier to break and tint and some can cause problems when surfacing and edging. Transparency Except when used for tinted lenses, all ophthalmic lens materials must offer optimum transparency with no, or very little, colour. They should retain this state over time. The apparent colour of a lens material is determined by the chromatic composition of the light which it transmits. If the lens transmits all wavelengths of the visible spectrum, the lens will appear transparent or ‘white’. If some colours are absorbed, the lens will take on a ‘tint’ – for example if the blue wavelength is absorbed, the lens will have a pale yellow tint. Unfortunately this effect happens when a material is designed to absorb ultraviolet radiation, it appears slightly yellow. To overcome this, the material is either given a slight brown tint to cover the yellow tinge, or chemicals are added to the mix (blue colourants) to ‘brighten’ the material and compensate for the yellow tint. This is usually the case for the higher index plastics.

Seiko www.seiko-optical.co.uk

ma sm on the market. Seiko have taken the correc on of as gma sm to a new level by crea ng AZ lenses which incorporate aspheric designs on both the front and back surfaces. They are referred to as being ‘doubleaspheric’ lenses to minimise spherical and as gma c aberraons up to the edge of the lens. By aligning the focal points of both axes in a very large zone of the lens, sharp focus and natural vision are achieved. Visual comfort is par cularly outstanding for wearers with cylindrical prescrip ons. The higher the cylindrical power on a conven onal aspheric lens, the higher the uncorrected aberraon in the second principal meridian. An op mum result is achieved through producing aspheric curves on both surfaces that correct as gma sm in all meridians. Seiko have designed their double-aspheric lens to compensate for oblique distorons at the edge of the lens. The centre of each lens incorporates spherical design, allowing for easy adapta on with vision being almost distor on free right up to the lens edge. Although AZ lenses are designed primarily to improve wearer vision and comfort, the double aspheric design can also reduce lens thickness by up to 10 per cent when com-

pared to a normal aspheric lens of equivalent power, index and diameter.
