e have become well accustomed to reading about the interface of technology with eyecare. We are all familiar with increasingly sophisticated computer-controlled lens crafting kit. We’ve seen spectacles with embedded cameras and computers, and we’ve even seen contact lenses concealing miniature circuitry, for example, to monitor diabetics’ blood sugar. News from South Africa though, brings a further more literal twist to our ‘chips with everything’ culture. Researchers at the Agricultural Research Council in Pretoria have come up with a bioengineered strain of sweet potato geared to tackling vitamin A deficiency. This is a serious condition which, at its most extreme, can cause blindness. According to the World Health Organisation, it is prevalent in more than half the countries of the world – particularly in Africa and South-East Asia. Young children and pregnant women are most at risk, and the WHO estimates that, across the globe, as many as 250 million school-age children may be vitamin A deficient. Researchers point to early successes in the varieties they have so far produced – with strains scoring high in the volume of vitamin A that they have delivered and, crucially, in taste tests. It is very much a case of yam tomorrow rather than yam today though, because the scientists have further to go. They report that more work is needed to increase the blight-resistance of bio-fortified potatoes. If the South African Agricultural Research Council’s plans do eventually bear fruit, however, then they could presage a huge reduction in vitamin A deficiency, with corresponding improvements in people’s sight. Potatoes are the only root vegetable popularly known to have ‘eyes’. Fitting then that they may yet prove to be the root of improved eyesight for some of the world’s poorest and most vulnerable inhabitants.

Spectacles andotherservices f not since time immemorial, at least for several decades past, spectacles have accounted for around 70 per cent of retail ophthalmic turnover in the UK, higher than in other similarly mature markets either side of the Atlantic. This has been a significant factor in determining the shape of the optics industry: retail relationship. Could this alter, as more retail opticians invest in high unit value eyecare equipment like multi-functional retinal cameras or optical coherence tomographers (OCTs)? Even if such high unit value instruments are supplied on the easiest terms the industry can devise, the investment is significant; a retail optician undertaking it is surely obliged to make his or her investment pay in practice. It would be difficult to avoid a change of emphasis from eyewear to eyecare in the process. Could spectacles and their supply chain suffer by being de-emphasised? Non-optician retailers like the UK’s Glasses Direct encourage this effect. This firm mounted an aggressive TV advertising campaign during summer 2015: young female patient picks out a frame at the opticians, faints on seeing the price tag, is pleased and reassured by the choice and service Glasses Direct offers. Inter-

estingly, lenses hardly feature, other than as ‘free prescription sunglasses’ thrown in to the offer, though in the off-line ophthalmic world lenses typically account for more than half of retail revenue derived from spectacles. Also interesting is first this advert’s clear evidence that big, deep-eye frame styles are in trend in the UK as elsewhere in Europe, which should enable inferences to be drawn about the market’s accompanying lens requirement. The clear implication is that male consumers are Glasses Direct’s real target market.

Consumers’ price conception The campaign was designed to trade on and reinforce the UK spectacle consumer’s perception that retail optical practices charge more for spectacles than these goods warrant. On the other hand, consumers offered eyecare services above and beyond the core eye test necessarily come to these offers fresh, without preconceptions, giving the practitioners more chance of presenting their real value fairly. One thing is certain: in the UK, NHS eye test fees will not make any substantial extra contribution to UK retail optical revenues in the coming year. After


InternationalSCENE exhaustive negotiations, these will rise by a mere one per cent, to £21.31 per test: well under half the real cost of providing it, professionals estimate. Such parsimony must make new eyecare services look more than ever the way of the future. Moves by professional organisations elsewhere in Europe suggest they agree.

Specsavers To date, independents, now making up in numbers little over 25 per cent of the UK retail ophthalmic market, have led the charge to take up new eyecare equipment supply offers. But they are not alone. Regional chains, and at least one national operator, are also rumoured to be dipping at least a toe in these waters. What are the plans in this context of Channel islands-based internationalist Specsavers? Specsavers now hold the lion's share of the eyecare and eyewear market not only in the UK but in the Republic of Ireland, is the second biggest retail player in the Netherlands, has rapidly come to dominate the Australasian scene, and is still expanding. Interestingly, one reason the NHS refused opticians a more generous eye test fee rise was that, today, more practices are opening than are closing in the UK. Specsavers are reported to have increased their turnover by more than nine per cent in the year to mid-2015. Now, as throughout their history, they have attracted remarkably little animus in the process, certainly from independent competitors. No chain anywhere has had more success with the franchise concept on which they were built up. Group success cannot be simply the question of a consumerfriendly name, though Specsavers was surely an inspired original choice in bargain-hunting Britain. Consumers in their droves clearly appreciate the service and product mix they receive from what is still a family and professional-led group. In the UK, Specsavers have been voted the consumer’s ‘most trusted optician’ year after year. Who is now in talks with Specsavers over ‘new service’ equipment (or, who is not?) The outcome may help to the international future relationship between optical retail and the supply industry for many years ahead. Last time this column was written, the economic focus was on beleaguered little Greece: to Grexit from the Eurozone, or not to Grexit? Today, Greece still faces the alarming combination of another election’s

aftermath, and creditors who seem less willing to countenance debt forgiveness, more intransigent, the nearer debt payback time approaches. But now, in Europe, with the Eurozone characterised as resurgent, who apart from the Greeks cares? The markets have something far bigger to worry about - China. ‘Turmoil’ was widely reported as the Northern Hemisphere's summer turned to autumn, as a succession of yuan devaluations reflected ‘slides’ in manufacturing and, especially, exports, and one month's capital outflows topped £75 billion. The Chinese stock market lost 30 per cent of its value (equivalent, as one gloomy commentator pointed out, to a whole year's economic output for the UK) in little more than a fortnight. This steep downturn was reflected not only in the anxious faces of, mainly, Chinese investors large and small, but more widely. Commodity prices, including the metals sector and oil, plummeted along with demand from Chinese industry. Planned central bank interest rate rises in the USA and UK were forecast for postponement; it was even suggested that the UK base rate might be cut from 0.5 to 0.25 per cent to reflect the effect of any prolonged Chinese problem on inflation here, though this has been fairly authoritatively denied. ‘Don’t panic – yet’ seemed the watchword as this issue went to press.

More stability in China No-one disputes the slowdown in Chinese economic growth, from perhaps 14 per cent at its peak to (commentators agree) probably four to five per cent now – still higher though than the ‘resurgent’ Eurozone is managing. The experts appear however to be agreed that the situation, unavoidable given increasing Chinese prosperity, is now stabilising. ‘Market forces’ are at best, not wholly rational, and since the crash of 2008 seem perpetually in pursuit of a crisis, real or imagined. The jumpiness, bordering on panic, which that bad year induced, has not yet subsided. We are perhaps unwise to load too much of our faith on to a new, raw, untested and inwardly focused superpower. And, as another expert commentator observes, ‘it is never possible to be sure that we are not about to face disaster’. So far as ophthalmics is concerned, we may see more – and show organisers may know more – when next spring’s MIDO and Vision Expo take place.

Optical Workers’ Benevolent Fund Ill health, issues of ageing and genuine problems faced by those who have worked within manufacturing optics may be eased by a grant from the Optical Workers’ Benevolent Fund. ‘At any one time we have around 10,000 people working in all branches of manufacturing optics. There are people facing issues who need support. We hear about some distressing cases of hardship faced by those who have worked within optical manufacturing but who do not qualify for other assistance. We aim to help those who have worked loyally to further our industry’, say the trustees. The charity is supported by the Federation of Manufacturing Optitians from the proceeds of Optrafair, and by donations from UK optical companies. It is affiliated to the Wiseman Memorial Fund, after Max Wiseman who founded an optical manufacturing business in 1898.

German help offered to independent practitioners Retail optics is undergoing huge changes as online retailers are becoming the biggest presence after chain stores including supermarkets. According to a report by Mintel, the share independent opticians hold of the market is now down to an alarming 28 per cent. It is also estimated that they are closing at the rate of approximately 300 per year, fashioning a stark reality for the future. Other figures confirm that optical public spending reached a record high in 2014, proving that the shift in market change is not in public spending, but rather market presence. However, it is claimed that the independents can still sustain a fair share of retail distribution with the support of the Specsfactory, of Wildau, Berlin. Founded in 2012 they have partner opticians throughout Europe, and their own manufacturing facilities. Specsfactory are seeking to create an extensive network of partnerships with independent practices, and are inviting independent UK practitioners to seek their help, claiming to have more than 400 partner opticians in Germany.

Things that should never have happened There are any number of things in history, good and bad, that never should have happened, argues Consultant Editor Richard Chaffin, citing examples of events culminating in wars that cost countless lives and changed history. In the optical world, one thing he believes never should of happened was the United States drop ball test, and the subsequent emergence of polycarbonate as an ophthalmic lens material. United States Senator from the state of Minnesota, in a casual cocktail conversation, was told glass spectacle lenses were dangerous to the wearer. He took that seriously, went to the FDA (Federal Drug Administration) and had them institute controls of the ophthalmic lens industry that resulted in the drop ball test. The FDA promulgated regulations that specified a steel ball five-eighths of an inch be dropped on a lens from a height of 52 inches. A performance test was to prove the lens could survive the impact and therefore be safe to wear. The industry was taken totally by surprise. There was no scientific data to back up the drop ball test. None of the lens companies had performed any research on the amount of force causing glass lenses to shatter. In addition, there was very little, if any, evidence that glass lenses were shattering or any eyesight was lost except in cases such as a person wearing glasses being shot through the eye or

10

www.optical-world.co.uk

running their car into a bridge abutment. Clearly these circumstances had nothing to do with the safety of glasses. However the rules were passed and the US lens industry had to comply.

Manufacturers in a quandary At the time American Optical and Bausch & Lomb were the largest lens makers in the world. They did not know what to do. Their glass lenses were made from 0.8 to 1.2mm in centre or edge thickness. American Optical and Bausch & Lomb also produced glass lenses for industrial use that were 3.0 mm thickness. Industrial lenses were factory hardened by heat-treating. However AO and B&L also had a third line of glass lenses they manufactured and sold. These lenses were marketed as ‘Dress Safety’ lenses and were a bright idea of the lens sales managers to increase lens sales. Dress Safety lenses were a compromise 2.0mm thickness and were to be hardened in the laboratories with heat treatment units.


The FDA said these 2.0mm lenses when treated in the laboratory and drop balled would satisfy the drop ball test. There was no prior research data to prove this. As a matter of fact, glass lenses of lesser thickness, when polished sufficiently, could also pass the drop ball test.

Product liability and plastic lenses There was the opportunity for lawyers in the US to argue that any lenses dispensed under the 2.0mm minimum were not as safe as possible. Product liability pursued in the US courts became very lucrative when any lens broke. There were a couple of bumps in the road. Shortly after the drop ball regulations went into effect there was a scare that the regulations had caused a major problem for treated lenses from so-called ‘spontaneous breakage’. People found their lenses shattered overnight on their bedside table or when walking on the street with a sonic bang or sharp noise. Heat-treated lenses create a thin layer of glass under tension. If that layer is compromised by an abrasion or scratch the lens will explode in pieces. Chemical strengthening of glass lenses provided a thicker layer of hardening and alleviated most of these problems. Plastic lenses did not have to be drop balled in the US laboratories because the FDA allowed plastic lenses to be batch tested at the factory level. That was a big advantage for plastic lenses over glass, albeit plastic lenses at 2.0mm thick were half the weight of glass. At the time CR-39 lenses were growing in use and the drop ball test pushed them over the top in the US where glass was now required to be thick and heavy. Polycarbonate, another type of plastic, entered the market. A thermoplastic, polycarbonate was being used in helmets and visors because of its safety characteristics. A softer material than CR-39, polycarbonate is injection moulded and has to be coated. Not as good optically, polycarbonate was promoted for glasses for its claimed ability to stop bullets. The US market accepted it as US lawyers argued product liability cases on the grounds of ultimate safety. Polycarbonate, aside from safety, has drawbacks when used for ophthalmic lenses. It is chemically not as stable and has a lower Abbe value than CR-39 or glass. Some polycarbonate lenses are not dyeable. The optical world did not pay any attention to the United States and 2.0mm glass and plastic

lenses. Outside of the US, the ISO and the marketplace did not find any problems with the safety of glass lenses or CR-39 plastic. Polycarbonate has not been able to establish itself in any lens markets outside of the US. Even with strong backing by Essilor it accounts for no more than 8 per cent anywhere in Europe. Polycarbonate does share a major part of the US market with CR-39, with glass accounting for less than 4 per cent. Polycarbonate is not a classic case of ‘product substitution’ in the manner CR-39 is, replacing glass. Polycarbonate is not needed. Better optically qualified plastics with polyurethane components will supplant polycarbonate. They have higher indices and good if not equal safety. CR-39 will continue to have its place in the market as a product with good optical qualities as the world’s glass lens markets continue to shrink. Higher index plastics will grow and share the marketplace with CR-39, but there will always be some glass for specialty needs. The United States should do away with the drop ball regulations and get in line with the rest of the world. Glass lenses were safe at 0.8 or 1.2mm. The number of eyes lost from broken glass lenses was never determined. The whole world (outside the US) was not wrong. Plastic lenses are inherently safer from impact even with adverse coatings. The US also has to rein in its litigious appetite and control lawyers suing for product liability.

Lens materials Lens materials are usually described and judged by three characteristics: index, Abbe number, and weight. There are trade offs as one or other of these values change, affecting the values of the other two. Of course it is not quite as simple as that. There is the question of transmission of light and colour or clarity. Safety of lens materials is important but has never been a defining element. Today’s ophthalmic lens market has quite a few choices, with glass encompassing indices from 1.52 to 1.90 with varying Abbe values and weights as the indices rise. Plastic lens materials now stretch from 1.499 to 1.74 indices, with differing Abbe values and weights. But only one of these materials stresses impact safety. The optical world has recognised what has happened. Now it is time for the United States to wake up.

Lensmeters and lens measuring equipment The original optical instruments for measuring lenses were termed ‘focimeters’ and were devices intended purely for measuring lens powers, axis and prism direction – hence the name – a meter (an instrument for measuring) for determining focal lengths of lenses. They could also be used for marking the axis direction and lens centre. But in their new guise – as ‘lensmeters’ – they can now do far more, the extra sophistication having been made possible by the introduction of microprocessors, plus LCD and plasma screens, which have allowed designers to add more automation and sophistication to the instruments.

Tony Jarratt, Technical Editor ith lensmeters, it is now possible to automatically display the results, recognise a progressive surface, calculate the addition and in many cases determine the optical centres (PD’s) of the spectacles. In addition, with the latest automatic models it is also possible to allow for differing ν values (Abbe No.) – which ensures increased accuracy when high index lenses are being measured. Some can also measure and display transmission data for the lens under test. [It should be noted that in the past, manufacturers used the term focimeter to describe eyepiece and projection models with internally moving optical systems and the newer automatic LCD designs without moving parts as lensmeters. Now virtually all producers refer to both types as lensmeters, the old term focimeter having become something of an anachronism.] Basic types of instrument Modern instruments can now be divided into three basic types: Type Manual Semi-automatic Automatic

Display Eyepiece LCD display LCD Display

Using this ‘categorisation’, the following basic definitions can be supported: Manual A design, in which the operator adjusts measuring scales

12

www.optical-world.co.uk

by the use of control knobs, and then views the results on an internal or external screen. Semi-automatic Some operations are automated or guided – such as centring the lens in the beam path of the instrument, rather than visually centring the target of the machine. Automatic The majority of the operations – such as lens centring, PD and add determination are automatically carried out by the instrument without operator intervention. Some have even greater sophistication, being able to determine the refractive index of the lens material, or the UV and visual transmission values. Two main displays are used in the design of modern lensmeters. Eyepiece design The power target graticule of the machine is viewed through the eyepiece of a telescopic system. Usually, the power readings and axis scale are also displayed on the internal screen, but on some machines the readings are viewed on external scales attached to the operating wheels or knobs. The results can only be viewed monocularly and the eyepiece must always be adjusted for any residual refractive error of the operator, before use. These are the most basic machines and are suitable for those requiring only occasional usage, or where a small budget is involved. Some models are battery operated, making them suitable for domiciliary use, where the weight (and cost) of the more sophisticated machines would make them unsuitable.


Digital LCD Liquid crystal displays – similar to those used in portable computers – sometimes backlit for clarity – enable the maker to incorporate various designs into the screen layout. This type of screen has superseded the old optical projection screen (see Figs 1 and 2). These screens are now supFig 1: Example of an LCD screen plied as colour LCD’s – necessary when the instrument is capable of displaying a power map (see below).

Fig 2: Typical results display

Main components of the lensmeter Targets and screens The basic optical lensmeters (eyepiece) make use of target graticules, which are lit by a light source within the instrument. The resultant light beam is then brought to a focus on a screen and the image that is produced is viewed by a telescopic eyepiece. When a lens is introduced into the beam path, the system is placed out of focus and a blurred image results. By adjusting the controls, the image can be brought back into focus – the amount of this adjustment being converted into dioptre readings on the instrument scales. At the same time, the target can be used to indicate the axis of the cylinder, by aligning the image against an axis protractor etched on the screen. The targets are normally one of two basic designs: (a) A corona or circle of dots (when in focus) which become blurred when a lens is introduced. If the lens is spherical, the target can again be brought back into focus as a sharp ring. If a cylinder is present, the dots will be drawn out into a series of lines, which will run along one of the principal power meridians. It will then be possible to bring the lines into focus at two distinct points on the power scale – at right angles to one another. Each will indicate one of the principal powers. Taking one of these as the sphere power, the difference between the two will indicate the cylinder power.

The direction of each of these series of lines will indicate either the plus or minus transposition axis - as appropriate. These axis directions can then be read off against the protractor scale. (b) The second type of scale is composed of crosslines, one long set – stretching across the screen. Another set at 90° to the first, and sometimes shorter in length, indicates the other meridian. Each set can, in turn, be brought into focus – thus indicating the powers in the same manner as the ring target. Each type of target has its supporters. The choice is really down to personal preference, as they both provide the same results with virtually the same degree of accuracy, although the ring target is not so easy to focus for very low cylinders powers. Each target screen will also have etched markings, which are used to indicate displacement of the light beam. This displacement allows the operator to position the lens correctly; when the target appears in the middle of the screen, the lens is correctly centred. This scale is also marked in prism dioptres (or parts) and once the lens has been correctly centred in the instrument any prescribed prism can be read off from the scale. The same scale can also be used when marking a prismatic lens prior to glazing. The target is aligned against the required degree of prism (taking base direction into account) before marking. The eyepiece of the ‘eyepiece’ type of focimeter can be adjusted to take account of any un-corrected spherical prescription that the operator may have. This ensures that the instrument is correctly adjusted to zero before use. Obviously failure to regularly check this setting can lead to incorrect results. A range in the region of –5 to +5D is usually provided. The latest lensmeters The older optical instruments do require a reasonable amount of experience to obtain accurate and consistent readings. For instance, some target graticules are not easy to focus, especially with low powers and cylinders. The latest automatic machines remove this dependence on the operator. The machine carries out the focusing and axis determination, calculates the addition for multifocals and, in many cases, even measures the PD’s. These can be shown on the screen, as monocular or full binocular PD’s as required. Automation of power measurement also allows a higher degree of accuracy to be introduced. Optical machines can be read, by a trained operator, to 0.12 with a reasonable degree of accuracy, but the latest models

can improve on this. They will read to 0.12 without any trouble and many can even be set to read to 0.01 (one hundredth of a dioptre), if this is required – although this introduces a degree of accuracy which is not possible to produce in the surfacing shop! Abbe No., or ν value With the large number of higher index lenses on the market, the effect of the lower Abbe numbers needs to be taken into account. The lower value and the use of monochromatic light within the system (produced by LED’s – normally in the green range of the spectrum), can affect the effects of dispersion and therefore the accuracy of the readings. The latest automatic instruments can be adjusted or pre-set to take account of the Abbe number, thus ensuring accurate readings for these modern high index materials. In fact, some of the latest designs automatically detect and allow for differences in the Abbe No. Lens power mapping and image recognition The very latest instruments, still being introduced, have taken automation to new level. Some are fully automatic; the operator only has to place the lens in the machine (or completed spectacles on the table) and the system does all the work.

Fig 3: Progessive error map

These latest instruments can be classed as lens analysers, rather than lensmeters, taking the process of lens recognition much further than was previously possible.These latest designs feature two highly sophisticated technological advances – Image rcognition, for determining the markings on a progressive lens, or the segment shape (and even size) of a bifocal and Hartmann Wavefront technology for power mapping of the lens surfaces (Fig 3 shows a typical progressive area error map). Image recognition allows the instrument to determine which type of lens it is analysing. It can then choose the

14

www.optical-world.co.uk

correct mode for further analysis. Wavefront technology allows the instrument to take multiple measurements at the same time. This multiple measurement mode (combining recognition with Wavefront technology) means that the software can analyse the geometry of the lens surface(s), rather than just measure a single power. Using lens data from the entire lens can allow the system to determine (depending on lens type): • • • • • • • • • • • • • •

Lens type Sphere powers Cylinder power Addition (where applicable) Axis Direction and orientation of the progressive corridor Shape and size of the corridor Power gradient for a progressive (shown graphically) Position and possibly the size of a bifocal segment Monocular and/or binocular PD’s Prism or decentration Fitting heights Refractive index (some models) Automatic Abbe No. adjustment (some models)

Many of the latest instruments have a built-in printer for recording the data (see fig 4). It can be seen that the latest lensmeters or ‘lens analysers’ are extremely sophisticated instruments, capable of carrying out all the tasks for full lens recognition and measurement required by today’s laboratory. Note that Hartmann Wavefront technology is based on a 'micro-optic' matrix. Each micro-optic is responsible for analysing a small part of the entire lens. In one instantaneous measurement, the user can now receive the equivalent of multiple measurements. This technology has no moveable parts, providing the user with a faster, more accurate analysis from all directions of the lens. Because there are no motorised parts, the system is Fig 4: Example of ticket print-out maintenance free.

Fining pads New from PSL is their Transformer all-materials fining pad, which transforms as it fines from the original coarse state to a smoother, transparent condition. The innovative composition of this one-step pad allows it to breakdown during processing by fining the lens at different intensities, starting rough for heavy stock removal and smoothing down for an ultra smooth lens finish that a second fine produces. The pad achieves consistent stock-removal on all lens materials and has a cloth backing helping the pad to conform to the tool and making removal easy. For optimum results, PSI recommend using the pad with their Yellow Ultimate polish pad and Free-Form AR polish. For further details visit: www.LookToPSI.com
