e go to press with Britain in the grip of political fever – well perhaps a mild degree of angst – in the run up to the General Election on May 7. Whichever party is victorious, this summer will unquestionably see a major drive to reduce national spending as the incoming government attempts to achieve economic equilibrium.

W

While every political leader has been busy paying assiduous lip service to the sacred duty of protecting the nation’s National Health Service, nobody should be in the slightest doubt that once more it will be subject to stringent economies, how swingeing the cuts prove being very much dependent on the political complexion of the incoming administration. Whoever wins, and there remains a distinct possibility there might well be a coalition government, our industry will inevitably be required to bear its share of the pain, whether this is largely confined to the retail side, or also hits manufacturing and the prescription labs. As OPTICAL WORLD has repeatedly pointed out before, the fact that optics is on the periphery of the NHS scarcely makes us less vulnerable. In spite of the claims from the outgoing government to have created a healthy economy over the past five years – at a time when most nations were still suffering the depredations of the global economic meltdown – workers continue to be asked to exercise wage restraint, while the banks, whose reckless speculators were the cause of the world economic crisis in the first place, seemingly fail to understand the meaning of the word. Nationally, we may have staged a welcome recovery, but industry could nevertheless be in for some hard times ahead.

InternationalSCENE

A real Bric? n India-based optical company, Contacare, founded in 1987 in the state of Gujarat, showing products, some of its own manufacture, from both the contact lens and the ophthalmic lens sectors, joined firms based in France, Germany and Korea on the always relatively short list of overseas exhibitors at Optrafair 2015. The list of visiting eyecare professionals of direct or family origin in the Indian subcontinent was considerably longer. Was doyenne of women optometrists Kusoom Vadgama, an important contributor to professional progress since her arrival here from East Africa in the 1960’s, among them? If she was, the writer, alas, failed to track her down to renew an old friendship.

Professional debt Not for the first time this column acknowledges the debt which modern ophthalmics in the UK, especially the retail ophthalmic business, owes to practitioners descended from families in the Indian subcontinent. Individuals have also made major contributions to optometrists’ and opticians’ education, and to ophthalmology, where also their work both in developing innovative concepts and in implementing those concepts has been considerable. Optrafair this year took place within a business cli-

mate at last growing easier: UK inflation at zero for the first time since records began, growth in gross domestic product now known to have reached 2.8 per cent for the year 2014, more people in work (nearly 19 million) than ever before. Look more widely, however, and the picture is stormier, despite a peaceful recent election in the African continent’s most populous and potential-rich country, Nigeria, and some evidence of the tide turning against violence in parts of the Middle East. Here in Europe the Eurozone is in deflation; Greece and Germany remain at economic loggerheads, with a divisive ‘Grexit’ from the European Union still a possibility. Meanwhile on the wider economic scene the USA and China are locked in none too friendly competition to attract backers for their rival international investment banks.

Successful quartet It is pleasant, therefore, to record what looks like continuing progress by at least one of the Bric’s: the original quartet of emerging markets identified by a US economist back at the turn of the century as the countries most likely to succeed, and to give the ‘Old West’ a run for its long-industrialised money. All four Bric’s fared well in the short term, with the People’s Republic of China in undisputed pole position. Dazzling the world with years of double-figure GDP


InternationalSCENE growth, China became the world’s source of choice not only for ophthalmic frames, and some lenses, but even for prescription manufacturing, thanks above all to its low labour costs. However, times have changed now; Chinese growth year on year is well down from its peak, labour in relatively short supply owing to changing demographics. Nor is China alone. Both Brazil and Russia are stressed. Brazil (host to next year’s Olympics) has felt the effects of the oil price slump; Russia feels them too, and is also smarting from the sanctions imposed in reaction to its perceived East European ‘adventurism’. India however, remains what looks pleasantly like a solid Bric, not least since changing government after last year’s national election. Indian GDP for 2014 was up 7.5 per cent (some 2.5 times the UK rise!). For the first time ever, the country overtook China with this statistic, leading some economists to predict that India, with its 1.25 billion population, will become the world No. 1 (passing the USA as well as China) by the mid-century. Reason to be cheerful? Not, perhaps, if you are among the still all too numerous poor eking out life on less than a US dollar a day. But half India’s population is under 25, with clear future workforce implications. New Prime Minister Narendra Modi has already introduced major business reforms which are designed, among other benefits, to make inward investment easier, even in retail business, hitherto a legalistic and bureaucratic nightmare. Optical chains, please note if you have not already done so. The international community has also been promised that infrastructure problems, especially power and transport, will be tackled urgently. The Indian middle class, and its consumer power, are growing. While nobody could deny that this Bric has huge social problems to be addressed, the Indian subcontinent’s ‘expat’ population in countries like the UK has demonstrated the work ethic and the creativity India can draw on. Ophthalmics provides a good example, right here and now.

A ‘vision problem’ and its consequences As this column was preparing for press, Britain was in the grip of a forthcoming, high-pressure, hard-to-call General Election campaign, with polling day to come on May 7. The political headlines were however being usurped by the shocking news of a German airliner crash in the French Alps, seemingly caused by a young co-pilot set on suicide and on taking a planeload of passengers with him.

The reason behind this truly awful event? German co-pilot Andreas Lubitz may, it appears, have been suffering from depression. His behaviour, however, has also been linked in press reports to a (so far unspecified) eye problem said to have already reduced his vision by 30 per cent – and if, as implied, progressive, likely soon to curtail his flying career. German sources have suggested the problem was psychosomatic or the result of trauma. Equally, one would have thought such vision loss, unexplained or not, cause enough for depression in a young flier. If the ‘eye problem’, involving a possible loss of visual acuity or visual fields, was organic in origin, it is hard to guess what its cause might have been in a 26 year old seemingly healthy male who had presumably passed the demanding vision tests undergone by would-be pilots when he was recruited. Possibly optic neuritis, a known precursor of multiple sclerosis, or early-onset glaucoma? Whatever the cause – and it may never be widely known thanks to strict German confidentiality laws – if a vision problem did contribute to the deaths of so many, the after-effects for eyecare professionals, their suppliers and at least some categories of their patients may be long term and widely felt.

Grand Vision GrandVision, the self-styled ‘World’s biggest opticians’ – owners of UK chain Vision Express – is claiming international sales up 8.5 per cent to £2 billion in its first full-year report. Growth was boosted, GrandVision says, by a stronger GDP and by acquisitions: it took over British lens manufacturer Rayner in 2014. In the UK, Vision Express has been running a high-profile TV consumer ad campaign in Spring 2015, majoring on the indepth quality of its eye test.

Lightbulb moment The UK’s National Graphene Institute at the University of Manchester has hailed what it hopes will be a first commercial success with the launch of a lightbulb design incorporating graphene nanotechnology. An infinitely thin strip of this new material (noted in a 2014 International Scene report) will, it seems, give better quality illumination, for much longer, at reduced running cost, than even the most advanced conventional light sources. Could applications in scientific laboratory instruments, perhaps even in ophthalmic consulting room instrumentation and prescription lab machinery, lie ahead?

Adlens ‘Design for Life’ exhibition Adlens, the global leader in adjustable focus eyewear, took part in Design for Life exhibition, held in Barcelona at the famed Museu del Disseny. ‘Design for Life: 99 projects for the Real World’ is an interactive temporary exhibition meant to show how design can be combined with a desire to change the reality around us, improving social wellbeing through the creation of products that make a real, personal difference. Some 99 design projects that epitomise this were carefully selected, and Adlens was among them with its innovative Adlens Adjustables eyewear. The multi-award winning Adlens Adjustables eyewear is built on Alvarez lens technology. Each lens is comprised of two wave-shaped plates that glide across each other to incrementally adjust the focusing power. This enables correction of over 90 per cent of spherical errors (-6 to +3 diopters) in those without astigmatism, significantly improving visual acuity in all kinds of situations. As well as being a uniquely effective product for vision care in the developing world, they are perfect for working with fine details, reading books or tablets, using computers, doing DIY, watching TV, and playing sports.

Work progresses on MEI’s new headquarters The expansion of MEI, a company specialising in the manufacture of corrective and sunglass lens production machinery, continues with the construction of new company headquarters, now under way, in Ponte San Pietro (Bergamo), a few kilometres from their current premises. The new base will have a floor area of 10,500 sqm, 2,500 of it to serve as office space and 8,000 for production and warehousing. At present, the firm provides work for 70 people at the Italian site alone, with an annual output of 250 machines. As Stefano Sonzogni, MEI’s president and technical director points out, ‘The new centre is meant to guarantee higher production volumes, resulting in faster delivery of machinery. The new premises, which are expected to open mid 2016, will be easy to reach thanks to their strategic position along one of the main arteries cutting across the Bergamo hinterland.

Vision Expo East 2015 Consultant Editor Richard Chaffin reports from New York he 2015 International Vision Expo East was held in New York City from March 19 to 22. As always, it proved an exciting occasion. All exhibitions create an environment that invites participation but more importantly they are the opportunity for all segments of the business to display their wares and meet their customers. Show visitors have the opportunity to see the latest and newest fashions and equipment. This long-established show has continually evolved along with the industry to provide the most valuable experience possible for its exhibitors and attendees. Reed Exhibitions, along with the Vision Council who are co-sponsors, changed this year’s event to make it easier for visitors to navigate and find the different segments of the industry. There was even an official Vision Expo mobile app available.

T

Separate exhibit areas

New York’s Javits Center housed over 500 exhibitors on two levels of the building. All the frame and accessory exhibitors were on level three where the Underground and Galleria were brought together in an area called Eyewear. Level one featured lenses, lens processing and technology, medical and scientific, low vision, and education. The two Vision Expos are the premier exhibitions for the United States optical market.

Vision Expo East, the spring version, is held in New York and a second edition, Vision Expo West, takes place in Las Vegas in the fall. In each case the majority of the exhibitors and exhibit space is devoted to the frame and accessory segments of the industry.

No distinctive frame fashion

This year in New York it was difficult to discern what the latest sizes, shapes, and colours will be for eyewear. There is no strong direction for frame sizes, as small and large are both being shown. Round or oval shapes seem to predominate and a mix of neutral, clear and bright colours. Sunglasses continue to show aviator styles, polarised, and wrap around with more emphasis on specialised glasses for individual sports as well as fashion. Several large companies dominate the frame and sunglass businesses. Brands or designer names are the major components of their displays. Thus there is a proliferation of small lesser-known brands with boutique styling. Frames and sunglasses are always of interest and make up the fashion end of the business.

Lenses and machinery

Lens manufacturers and machinery makers and suppliers shared level one of the Javits Center with Medical and Scientific. The two largest lens companies Essilor and Zeiss had several booths

for different product types. Essilor’s machinery division Satisloh featured a major display of automated machines for all the laboratory processes. They had a full production line with the software to organise and control it. Schneider Optical Machines, a leader in freeform technology, displayed their machines for both large and smaller laboratories, demonstrating their fully automated small machines, designed with the same technology as their large output machines, but compact and less costly. Schneider Modulo systems are all connected electronically for a history and support of each machine. The firm manufacture a full line of laboratory machines, including everything from blocking to a four-axis edger. OptoTech featured their full line of automated generating and polishing machines. To satisfy the demands of the large laboratories they have introduced their ASM Flash twin – a digital turning machine, which simultaneously processes two free-form lenses at the same time, offering three times the output of a single machine. This company displayed their automated line of machines that are suitable for both conventional and free-form laboratories. Coburn Technologies, an American company, had a large booth with all their edging, generating, polishing, and examining equipment. They demonstrated their new Cobalt generators both for smaller laboratories and for free-form processing. Coburn, a 60-year-old company, also supply a full line of consumables. Featured by A&R Automatics & Robotics was their AutoMapper for prescription lenses. It displays a map of the lens surface (free-form or conventional) and evaluates it for accuracy. A&R are makers of highly automated machines for inspecting, marking, and packaging lenses for both laboratories and mass manufacturers. They have been in business since 1983 and have a subsidiary in the United States.

Consumables

Cerium Optical Products, a leading UK supplier world wide of consumables for the optical industry, had an attractive display of products. The company is a true primary manufacturer of surfacing tapes and many other products. Their booth emphasised their dedication to innovation and quality in all their products.

10

www.optical-world.co.uk

In general, the machinery area of Vision Expo appeared to be well attended and quite busy. There was serious discussion among the exhibitors that as a result of the amalgamation going on within the industry, as well as other reasons (large retailers and health plans, etc.), there are large volume laboratories and ‘mom and pop’ small laboratories, but very few middle sized laboratories. A key component for the future will be full automation and sophisticated software. Ecological concerns will play a part in the future for all manufacturers and laboratories. Prescription lenses will be made to individual requirements in shorter and shorter amounts of time.

Lenses

In the lens area Essilor and Zeiss dominated with large displays. Zeiss was a primary sponsor this year of Vision Expo. In addition to their lenses, they showed their well regarded examining and medical equipment. Their lenses include not only the Zeiss designs (progressive lenses) but also the former Sola and American Optical products. Essilor, a clear leader in the lens area, featured their progressive lenses as well as lens coatings. In addition, as the now sole owner of Transitions, there was a large Transitions stand with their changeable and polarised products. Essilor had separate stands for their equipment and wholesale divisions. Rodenstock, represented by EGMA LLC, returned as an exhibitor after being absent for some time. They are building a laboratory in Dallas, Texas offering their lenses. International Vision Expo New York seemed to accomplish all of its objectives. The opening day was the occasion for educational sessions, followed by an evening of dinners honoring Ed Greene by Prevent Blindness America and the Vision Council. On the following day exhibits opened to a light snowstorm that did not seem to have any effect on attendance. Education, both free and for credit, continued throughout the day and the night was filled with receptions and parties spread around the city. The ensuing weekend saw more of the same for exhibitors and attendees, who departed happily on Sunday at the conclusion of another enjoyable meeting.

In this context, the industry can now utilise loose granular materials in the form of a liquid slurry, smoothing and polishing pads, produced from several different types of ‘abrasive’ and using many types of carrier material and more recently diamond impregnated foils. To this list we need to add diamond wheels, as they are used to grind lens surfaces and the edges of lenses when cutting to shape.
