e have commented in the past on the success of the long‐running ‘Should’ve Gone to Specsavers’ advertising campaign run by the large UK multiple. In the ads, unfortunate individuals find themselves in an awkward situation because of a blunder caused through their myopia. In a recent example, a naked man sits himself in what he takes to be a Turkish bath, only to find it is in fact the steamy kitchen of an ill‐tempered celebrity chef. It turns out, however, that reality trumps fiction. A recent report from the British College of Optometrists catalogues a host of allegedly true accounts of how patients have discovered, in either amusing or dangerous circumstances, that they need their eyes tested. These included an airline pilot who taxied his jumbo jet the wrong way down an airport runway. Several motorists discovered their sight needed testing after finding themselves driving the wrong way down one‐way streets. Another driver reported mistaking traffic bollards for children in the road. This seems especially puzzling as few British schools have bright orange school uniforms, and few British schoolchildren are less than 12 inches tall. In one unfortunate instance, a man mistook his hearing aids for cashew nuts, needing hospital treatment to retrieve them from his stomach. In another rather ironic case, a woman went into a high street opticians and began taking off her shoes and socks. She had evidently thought she had gone into the chiropodist next door. It is deeply worrying that so many people are so slow to notice their deteriorating sight. And to make matters worse, the College of Optometrists’ survey revealed that more than one in three of those questioned who had suffered a mishap through poor sight still put off having their eyes tested until some months after the incident that triggered their concern. However, it’s an ill wind though that blows no good. If nothing else, the College’s report has furnished the multiple’s advertising campaign with several more years of material.

February 2015



Cautionary tales n January this year came the newsflash – and it seems indeed to have flashed up, totally unexpected by most – that the mighty Google had halted sales of its Google Glass. Now characterised as a headset, ‘Glass’ had dominated the so-called ‘smart glasses’ sector ever since its much-hyped introduction back in 2012. Drawing support from across the ophthalmics industry to develop the initial product concept, launched as a consumer item outside the USA in the autumn of 2014, Google was still steaming ahead recently enough for a top speaker in OptiMunich’s renowned opticians’ education programme to plan featuring it prominently in his 2015 presentation on smart glasses. Some hasty revision to be done there, then! Meanwhile Tesco, with a proposed Google Glass app to help wearers find product data online or scan barcodes, had joined a growing list of optical or optically affiliated companies to league themselves with Google in product development or marketing, a list extending from Safilo to Rochester Optical of USA and Waterside Laboratories in UK. How have these been affected by the decision? And what have been the reasons for it? They include, opined a commentator, the US ban on wearing Google while driving ‘in the 2

name of safety’ and while visiting the cinema or other public entertainment spaces in the name of intellectual property rights – spying by another name. Dare one cite an overriding reason behind these – Google’s apparent failure to apply common-sense in answering the basic researcher’s question: What will the market think of this?

Rare defeat for Google

It is believed Google may already have sold up to 50,000 Glasses, at £1,000 each, to consumers mainly in the USA paying for the privilege of feeding their wearer experiences back to Google. How much did Safilo and others invest? No doubt Google’s giant reputation was a factor in this widespread consumer and corporate enthusiasm; yet this may in itself have been a cause in what one UK economist called ‘a rare defeat’ for Google. Viewing the clunky early versions of Glass, it is easy to believe that someone, somewhere in the rarefied echelons of Google’s management believed the power of the name would override all other considerations. Was Google, lacking intimate knowledge of what ophthalmics needs, always riding for a fall? The corporation insists the concept is not dead, but temporarily on the back burner un-

InternationalSCENE der new management, that of ‘smart thermostat’ development specialist US-based Nest Laboratories, which Google purchased in 2013. Glass’s future outlook may, however, be limited to specialist applications within the business sector, eschewing consumer sales. Could this ‘up like a rocket, down like the stick’ trajectory be seen as echoing another ‘smart glasses’ saga played out a little while ago? The tale of US-based Pixel Optics’ Empower, ‘the first spectacle lens to change focus electronically’, bears some likeness to the Google Glass story, but also profound differences. Like Glass, Empower may have been brought to the market before it was truly ready. And the retail cost – of £1,000 plus per pair – may, as with Glass, have been a holdback factor for sales, especially in the core US market. The background, however, was very different; Pixel Optics was no global giant, but a relatively small independent US company – albeit innovation-led like Google. Its researchers had close and considerable experience in ophthalmics, led as they were by an optometrist inventor who had already created the USA’s most favoured progressive lens design (along with notable design advances in the contact lens field). The capital for Empower’s development (reported to have reached £120 million) was not internally generated but came from a cadre of US-based private equity backers; failure of the project resulted from their waning investment enthusiasm when (your reporter understands) neither technical manufacturing problems nor Google Glass-like limitations on initial sales volume could be overcome fast enough. Again, as with Glass, the concept is not dead; there are hopes that more about Empower Mark 2 will soon be heard from Mitsui, whose new US division, as noted in this column recently, acquired the technology in 2014.

Hopes for the future

The global lens business remains in love with the ‘smart lens’ principle, with more than a double handful of products in this category arriving on the scene last year. In reality,

though, are individual projects always likely to be crushed by the opposing pressures of market need – obtaining sales return on investment fast enough, beating the competition to the post – and the setbacks in implementation that are almost inevitable with any truly ‘smart’ new lens category? The answer thankfully, is no. Ophthalmics in the past half century has seen at least two examples of successful innovation which would surely have been acknowledged as ‘smart’, had the term been in use in their time. Both added previously unimagined scope to the corrective lens function. Photochromics is one; the other progressive lenses.

The first progressive

The first progressive design – Varilux I – met with considerable and widespread scepticism (‘it’ll never work – and who needs it anyway?’) when optical engineer Bernard Maitenaz introduced the concept to Essilor’s management, following years of calculation utilising the primitive proto-computers of the mid20th century. Then, even bifocals were still newfangled in the eyes of many markets. But Maitenaz’s team, and, to their eternal credit, Essilor, having accepted the concept, supported it with patient, effective, big-spend marketing … and the rest is history. Even Varilux, it could be argued, was brought to the market before it was fully ready; subsequent generations of progressives, however, have underpinned Essilor’s rise to global gianthood in ophthalmics, become the profit mainstay of developed markets across the world, and facilitated the acceptance of ‘smart’ lens technology – free-form. Not a bad record, and one to give heart to today’s struggling ‘smart lens’ pioneers. In passing: Google Glass’s failure to make headlines at this year’s Consumer Electronics Fair in Las Vegas provided straws in an adverse wind for some observers. The headline makers of 2015 were mini-drones. Have optical suppliers yet begun assessing drones’ potential as delivery vehicles? With costs now well under four figures, it must be only a matter of time. W

New BSI for sunglasses Plano sunglasses and clip-ons are subject to a new BSI standard from March 1, 2015 in a move to globalise regulations, warns the Federation of Manufacturing Opticians. BS EN ISO 12312-1 was introduced last year with the understanding that the previous standard EN 1836 could run concurrently for another twelve months, with this transition period expiring at the end of February. ‘This is really a review and amalgamation of current international standards, highlighting the requirements for sunglass construction, materials used, robustness and impact resistance, as well as plano lens transmittance characteristics, and refractive power’, explained Eric Boinard, the FMO Standards Panel expert on sunglasses. ‘From the manufacturing point of view it is great to have one standard. Prior to this release the USA, Europe, Australia and China had different sunglass standards. Although Europe has only adopted this new standard so far, we are looking towards it being accepted internationally — that is the aim, following ten years of working together. ‘One of the most significant changes is the degree of information to be supplied with the sunglasses. This includes not only the name of the manufacturer, but also its address as well as a series of warnings when deemed appropriate’, added Eric, who is also global R&D Group leader for Polaroid Eyewear. BSI standards are available at a reduced rate for FMO members via, and the FMO is advising retailers to contact their local Trading Standards office if they have concerns about compliance.

Based on the bigger MC-380-X, the MC-280-X combines multiple process applications with small batch capabilities for the highest exibility. The MC-280-X AR coating system delivers the highest quality AR coatings in small batches. With the same sophisticated AR and mirror coating processes as the big Satisloh box coaters, the MC-280-X guarantees the best results.

Diamonds in optics Richard Chaffin, Consultant Editor iamonds were discovered more than 3,000 years ago in riverbeds in India. The word diamond originates from a Greek word meaning unbreakable or extremely hard. Diamonds are a pure form of crystalline carbon. They are formed as a result of extreme high pressure and heat. Although primarily formed deep under the earth’s crust they have a variety of sources and may even come in some cases from outer space. Natural diamonds are formed from both inorganic and organic sources of carbon dating back billions of years. The movement of the earth’s tectonic plates is related to where diamonds are discovered and mined. Most often they appear in the central area of these plates. Originally, diamonds came from India and more recently from South Africa and Brazil where they are mined. Also, Russia claims to have an area in Siberia that holds enough diamonds to supply the world’s needs for the next 3,000 years.


Gem diamond / industrial diamond

Gem quality diamonds are described by what is referred to as the 4Cs. The 4Cs are carats or 10

weight, clarity or brightness, clearness, absence of defects, and colour, transparency. There are natural gem diamonds and gem quality diamonds that are synthetically man-made. Industrial diamonds are referred to as ‘Bort’ diamonds. They lack the 4Cs. They are not transparent, have faults, and inferior colour. Bort is a word meaning error. However, these diamonds work very well for cutting, grinding, drilling and abrasive industrial applications. All the optical machinery makers use them, in some manner, in their generators and edging machines. Industrial diamonds come in a variety of shapes and forms. Both natural and man-made diamonds are used in the optical laboratory. In the 1950s General Electric in the United States, using extreme pressure and heat, was successful in producing synthetic industrial diamonds. These diamonds were formed in a blocky monocrystalline shape similar to natural Bort diamond. GE diamonds were first used in many industrial as well as optical applications. In addition, in the 1970s synthetically manufactured polycrystalline diamonds were made by chemical vapour deposition (CVD). In this case

high pressure and temperature are not needed. Diamond is grown with a hydrocarbon gas mixture. Polycrystalline diamond breaks down into smaller particles when used as an industrial abrasive. There are also diamond powders that are formed by crushing and pulverizing diamonds. These may be used in certain polishing applications. Industrial diamonds have been used in many industries as well as optics for the processing of hard materials. They came into the optical business in a big way more than sixty years ago. The idea of a diamond generator for toric optical lenses was developed after WWII. Before that, glass lenses were generated with diamonds only in special spherical machines. The optical laboratory did not have diamonds to work with and used powdered abrasives to grind lenses. The edging or finishing of lenses was accomplished with ceramic wheels. All of this has changed. Diamonds are now an essential part of the manufacturing, surfacing and finishing of lenses in the laboratory.

Single point and grinding wheel diamonds

The generating of progressive lenses has necessitated the use of a single point diamond-cutting tool. The computer directs the diamond to cut at thousands of points as the lens rotates to create the progressive surface. It is critical that the diamond has a specific design. The shape and cutting angle of the single point diamond are a proprietary secret of each machinery manufacturer. Spherical surfaces can be generated without a single point diamond. Grinding wheels come in many different shapes and sizes. They may hold diamonds in a bond made up of different materials such as copper and steel or in a mechanical fixture. In the case of a generator they may be cup shaped with a rounded face. To work properly grinding wheels have to be described with the type, size and concentration of diamond. In a bonded wheel the type of bond or matrix to hold the diamond is necessary. The cutting ability of the grinding wheel is dependent on the diamond grit size for a rough or smooth finish and how the diamond (and the bond) wears. Also of vital importance are speeds, feeds and pressures. These three factors always affect the type of diamond used and the end result obtained.

Therefore choosing a diamond for optical surfacing or finishing is a complex project. Experimentation is often the only way to determine the best type of diamond to use. The machinery manufacturer of surfacing or edging machines has to go through this process. No two generators or edging machines will necessarily have the same diamond-cutting tool. Another important use of diamonds is the diamond-impregnated wheel for edging. Edging machines, in addition, use several different diamonds in the shaping, bevelling, and drilling of lenses. These diamonds can be single point. There are some edging and finishing machines that work using a milling technique. These machines do not use impregnated wheels. All of these machines use several different types of diamonds that perform multiple operations on the lens.

Generating to polish

Progressive lenses have facilitated the laboratory’s movement to go directly from generating to polishing of lenses. This is a very significant advance for the laboratory with the elimination of loose abrasives and tools for fining and polishing. Diamond generating produces a much more precise surface and finish on the lens than tools. It has always been understood that tools slightly change the surface from the generator and therefore the desired curvature of the polished lens. Diamonds are able to produce a surface that is fine enough to be polished directly. In the case of a progressive lens this is a necessity. There is an old saying ‘diamonds are a girl’s best friend’. Diamonds are certainly one of the best friends of the lens makers. They are one of the hardest materials known to man. Diamonds are also regarded as one of the most valuable objects in today’s world. These facts apply to the world of optics, but for different reasons. The diamonds used in the optical business are not gemstones but industrial quality diamonds. Their value is not for beauty or love but for the difficult work they accomplish. The real beauty of diamonds, whether created thousands of years ago or in the 1950s or the 1970s (CVD), is not just on a finger but also as an essential part of modern technology. The diamonds of the optical world don’t just look good. They are good.

to the lens from debris or aluminas seeping in between the lens and block. This is especially true for lenses that are to be coated. • Make sure that lenses cool down at room temperature for a minimum of 30 minutes prior to genera)ng. Allow a lile longer for thin centred high index and polycarbonate. • Never rapid cool blocked lenses by immersing them in cold water or placing them in a freezer. This will cause thermal shock that leads to poor surface quality, suspect powers and waves. Temperature recommenda ons – • Op)mum temperature range for wet genera)ng, fining and polishing a taped lens is 55 to 60°F • Op)mum temperature for wet genera)ng, fining and polishing a non-taped, nonalloy blocked lens is 60 to 65°F. This temperature keeps the medium from ge ng too cold, which can cause the seal to break from the lens allowing polishing aluminas to seep in and cause microetching of the surface. • Make sure that the temperature is constant throughout all surfacing processes. Fining/smoothing – • Use a re-cycling system with filtra)on and chilling coils. It not only saves water and money, but also enables more consistent temperature control all year round. • Use a fining water addi)ve to increase the lubrica)ng proper)es of the water,


resul)ng in more consistent stock removal and improved surface quality. Polishing – • Match the temperature range to your fining line. • Use a central slurry system to make it easier to monitor and maintain a constant temperature. It will also provide proper filtra)on and Baumé consistency, so the same polish chemistry is delivered to all machines. Surface quality is improved while extending the life of the polish. PSI’s equipment was designed to provide a practical solution to enable labs to take control of their processing and at the same time provide cost savings. To enhance this philosophy all the items are available as separate components. The re-cycling and filtration systems, central slurry units and chillers are all separate purchases, thus allowing the flexibility to meet today’s requirements, whilst planning for the future. The 952 coolant filtering and recycling system is designed to replace the generator coolant tank or edger buckets. A large filter bag removes large pieces of lens material from the coolant before it is pumped back to the machine and provides easy waste disposal. Removal of swarf and temperature control keeps diamond free cutting and extends coolant life. PSI’s 952a fining water filtering and re-cycling system serves up to eight spindles, continuously removing abrasive solids and plastic particles, allowing fining water to be re-cycled. Filter bags are reusable and last at least four to

six months. Aluminium and steel construction provide maximum durability. The 993-2T filtration and re-cycling system for coolant or fining water is a two-tank system that provides an area for settling to occur before the fluid is sent through the filters. The system can be upgraded to include 19inch filters to cut down on filter changes (993-2T19), or can be downgraded to a one-tank system to accommodate labs with limited floor space. PSI’s 911 II central slurry system serves up to four spindles, with 2.5-gallon (9.5 litres) capacity. It is ideal for smaller labs or labs with dedicated glass or polycarbonate lines. Housed in durable stainless steel to reduce corrosion, there are no seals or bearings coming into contact with the slurry. The 911 central slurry system is ideal for larger labs and capable of handling up to 10 spindles, 5-gallon capacity. Other details as the 911 II. 913 central slurry system serves up to 12 spindles. It is of low design, making it compatible with Loh cylinder machines. Large 13 gallon reservoir provides better chilling action which can handle more slurry. A drain valve allows for total drainage of the tank, making cleaning faster and easier. Finally, the Hurricane filter system offers outstanding filtration with easy maintenance. It is a separator and a cartridge filter all in one – separating dense solids prior to cartridge filtration for extended filter life. Deep angled pleats are directed toward rotational flow for increased dirt holding capacity. It is a single ‘Jumbo’ cartridge that makes maintenance extremely easy.

Eyewire curving press Available from Western Op/cal Supply Inc, of Santa Fe, New Mexico, is a new eyewire curving press, the ideal way to perfectly mate the curve of the eyewire to the base curve of the lens bevel. The ECP presses the curve simultaneously in the same place on the top and the bo om of the eyewire; simply place the eyewire between the matching 6 or 9 base curved blocks and screw closed. Tighten less for other varia/ons in base curves. The 'ECP' is also used to narrow the bridge for a be er fit and to reduce the frame DBL. Measures 3in wide, 7.5in high, by 3.25in deep.
