his might be thought of as merely one of those academic studies that re‐ sult in a statement of the blindingly obvious. Funded by the National Eye Institute (NEI) in the United States and published last month in the jour‐ nal Ophthalmology, the research project compared the performance in early literacy tests of pre‐school children with uncorrected moderate hyperopia with the results of pre‐schoolers with normal vision. The study found that children with uncorrected long‐sightedness did significantly less well in the tests than their peers. Few will view these results with surprise. It may seem self‐evident that, in the words of one of the NEI program directors, ‘An untreated vision problem that makes it harder for children to see things up close can create literacy deficits that affect grade school readiness.’ Sometimes, though, researchers need to confirm what is previously strongly suspected but unproven. Without statistically validated evidence, policy makers may be reluctant to direct hard‐pressed resources into addressing an issue. Concerns about barriers to literacy have dogged politicians and education‐ alists in the United Kingdom as well as in the US. Money is pumped into fash‐ ionable reading and pre‐reading schemes but relatively little attention has been given to physical barriers that impede the learning of young children. Survey evidence in the UK shows that one in five children aged 12 and un‐ der has never had an eye test. The proportion of pre‐schoolers who have nev‐ er been sight tested is very considerably higher. There is a national ‘recom‐ mendation’ that all four‐year‐olds should have their sight checked but the UK’s College of Optometrists found that less than a third of local authorities in England are currently providing vision screening. Moderate hyperopia very often goes otherwise undiagnosed. Parents may be unaware of the condition, and another study suggested that 30% of par‐ ents are under the misapprehension that their child needs to be able to read and recognise letters before they can have a sight test. Meanwhile, children whose sight is hampering their literacy are commonly being misdiagnosed as dyslexic or with other learning difficulties like attention deficit disorder. Studies may sometimes tell us what we think we already know, but it is clear that there are still important lessons to be learnt – and our industry has a key role to play in extending messages to parents, pre‐schools and policy makers.

Optrafair and Optician

hen Optrafair opens its doors at Birmingham’s National Exhibition Centre (NEC) next month, Britian’s longest running trade and educational show for eyecare professionals (ECPs) taking place from April 9-11, will have, in effect, a new co-organiser. Partnering the Federation of Manufacturing Opticians (FMO) will be the familiar name the Optician, one of the world's few successful weekly journals for ECPs and optical retailers. The name is familiar; the journal began its association with the FMO in 2013. But this Optician is reborn. Published in Britain weekly since 1891, having been since the late 1960s a member of what is now international titan Reed Business Information group, OPTICAL WORLD’S contemporary is back now where it began, with an independent family owned publisher: one, moreover, which has a strong record not only for supporting health care journals but as an event and exhibition organiser, The Mark Allen Group was founded with just two titles (acquired from International Thompson by Mark Allen himself) in 1985. Its present day offices in Herne Hill, South London, are now home to some 70 publications. Mark Allen has not only acquired the Optician itself, but ‘all that goes with the brand’ explains chief executive office Ben Allen, Mark Allen’s son. Co-organising with the FMO of Optrafair was a key element in the agreement to purchase, along with the Mark Allen Group’s capacity to provide the facilities and services a major optical trade show needs. The Optician (both OPTICAL WORLD’S editor and founder Gerald Ward and the present writer are past editors) has a long tradition of linkage to exhibitions showcasing the optical supply industry going back to Bill Hardy (editor 1938-

65). The journal not only told the story of development and change in professional and retail optometry, but a story of a changing and developing industry, to which the profession – and optical retailing! – in the UK has always owed so much. it is good to see that the new publishers have upgraded both the Optician and today’s editor, Chris Bennett, who has also become the Optician’s publisher. Optrafair will be the new look Optician’s biggest test of 2016, with the FMO’s centenary show to follow next year. ‘This time we are focused on offering visitors and exhibitors at Optrafair, both from Britain and abroad, the best possible experience' says Ben Allen. ‘As well as showcasing the very best products in the market, Optrafair offers the chance for visitors to attain 50 CET points from some of the most well known and authoritative experts in their field. This year we have also planned for service, and facility improvements from arrival at the NEC showground onwards. We believe this approach offers the best opportunity of translating into better business for exhibitors.’ As for the show itself, the FMO’s Optrafair supremo Malcolm Polley confirmed as this issue went to press that 90 per cent of exhibition space is sold. The exhibitor rollcall covers the full span of modern-day ophthalmic product and service offers, with contact lenses more strongly represented, and presented than at some past shows. An extra strong wide ranging Continuing Education programme is promised to complement the exhibition itself. Last year’s ‘standing room only’ innovation, a ‘question time’ with big named panellists will feature again; this year’s theme ‘The Future of Optics: Technology in Practice’.


InternationalSCENE Equipment in focus Over the past 20 years, since the era when a fundus camera was the latest consulting room must have, and the ocular coherence tomographer (OCT) a mere gleam in the instrument designer’s eye, Optrafair has grown into an exhibition which ECPs utilise as an opportunity to browse through a variety of new-instrument options on show. For them and for exhibitors there is always the enticing possibility that window-shopping might shade over into a real-life major purchase. This trend has intensified as optometrists have advanced further into what was once trespass-proof medical territory. Your writer expressed, in a previous column, the fear that preoccupation with an ever-expanding clinical eyecare sector, could cause profitable and consumernecessary eyewear, especially lenses, to be neglected. There are other risks too, consumer and ECP perceptions may not match up. Results of two recent surveys (reported in the Optician) conducted by eye laser surgery firm Optegra and for the optical regulatory body the General Optical Council (GOC), indicated that for all of ECPs’ in CET and instrumentation, consumers still do not see them as eye experts. ‘The optician’, they consider deals with sight problems; for medical problems, most consumers would rather consult a doctor ... despite the fact that doctors themselves doubt their own competence when it comes to eye ailments. A companion study, by the UK’s Royal National Institute for Blind People (RNIB) also found that consumers aged under 35 neglect regular eye tests (‘too expensive’) though they acknowledge they should not. Even among presbyopes and pre-presbyopes, less than two-thirds of those questioned had the recommended two-yearly eye test. Attendance at Optrafair’s Continuing Education Sessions this year look likely to underline ECPs’ dogged determination to move further into the field of clinical eyecare. How can they persuade consumers to share their new self-perception as eye, not just sight, experts? How far should they wish to venture along this clinical path? When the Optician began contributing to professional and industry education, way back in the 20th century, Bill Hardy (an optician before he became a journalist) recalled how he had been trained never to diagnose an eye condition such as glaucoma or a detached retina, however clear the clinical evidence. Ophthalmologists would not stand for such trespassing on their ground. Now, a British optometrist who misdiagnoses or misses eye disease signs is liable to serious charges: manslaughter, even, in one

2015 case. When the value of an NHS eye test is still set at under £22, is ECP enthusiasm being exploited?

100% Optical Britain’s other optical trade fair, 100% Optical, was staged at London’s mighty Excel show ground over a long weekend last month. Previously, 100% Optical has claimed the crown of ‘UK’s biggest eyewear showcase’, but it was evident this year that the lesson of ECP interest in consulting room instrumentation has been learnt. New equipment on show here included the AngioAnalytics Angiovue, a non-invasive OCT-based device for imaging the eye’s vascular system, shown at Excel by Haag-Streit, together with novel add-ons for Zeiss’s Cirrus OCT. Heidelberg Engineering took the occasion of the show to launch a new Optometric Faculty. Not greatly in evidence at Excel: ECPs practising outside the UK. However, the UK model of optometric education and practice, based in turn on the USA, has become increasingly influential in Europe over the past decade. The USA influences the UK so strongly in large part because US firms took a lead role in supplying the UK industry when optometry was new here, when the industry in its turn was a major contributor to early ECP education and training. The UK eyecare-based model of professional development for ECPs has gained strength in parts of Scandinavia and the Netherlands, and in parts of Southern Europe from Malta to Spain. Even Germany, whose technical optics-based model has been a strong rival, has been moving towards optometry in the 21st century. Here, however, an educational approach which values ophthalmic lenses continues to weigh in the balance … as it does in the successful tradition of the Republic of Ireland.

Old and new As optometrists extend their activities into new territory, so does ophthalmology. Recently in the news was an Oxford, England, hospital’s success with the latest ‘bionic eye’ retinal implant, designed and made in Germany. This design will, it is hoped, prove really useful for a patient group ECPs cannot help, sufferers from the hereditary and progressive blinding disease retinitis pigmentosa. A newspaper headline extolling new roles for vintage lenses drew your reporter’s attention recently. Alas, these vintage lenses were not a new variant on Franklin bifocals, say, but anamorphic camera lenses to support the latest fashion for old style looks in period films such as Oscar nominated western The Revenant.

TURKEY

Silmo Istanbul, a promising edition Silmo Istanbul exhibition held in December, took place in the largest city in Turkey, at the crossroads between Europe and the Balkans, Central Asia, the Near and Middle East and North Africa. The exhibition demonstrated its relevance to both the local and international optics and eyewear sector. Held in the Istanbul Expo Centre, Silmo Istanbul hosted 106 exhibitors occupying 8,000m² exhibition area, made up of manufacturers from the Turkish optics and eyewear industry and companies from both Europe and Asia involved in every aspect of the sector: frames, lenses, contact lenses, materials, services, etc. It welcomed 8,970 visitors, an increase of 12.9 per cent on last year. The number of international visitors rose sharply, up 43 per cent on 2014. The organisers of Silmo Instanbul (Silmo Association and Comexposium for France, 24 Saat Ajans, publisher for the past 12 years of the trade journal 4Eyes, for Turkey) were delighted by this surge in visitor numbers, and plan to continue promoting interest in this new trade fair on the international calendar of optics and eyewear events. Silmo Instanbul 2016 will take place from 8-11 December 2016.

GERMANY

Increased visitor numbers at Opti 2016 Held over a three day weekend in Munich from January 15-17, it is claimed that opti 2016 recorded an 8 per cent increase in visitor numbers, with over 27,500 attendees from 81 countries at this year’s event. The total number of exhibitors at the show was 576 and for the first time there were more international than national companies exhibiting. The European industrial association (EUROM) also met for the first time at opti, as did members of the European umbrella organisation for optometrists and opticians, the European Council of Optometry and Optics (ECOO). Two new additions to the trade-fair portfolio met with a very positive reception. More than two thirds of visitors gave top grades to the focus topic ‘digital optometry’ and for the premiere of the new !HOT area in Hall C1. This area, with over 60 firms alongside the 120 independent and fashion labels in the YES area, forms the opti-Design Chamber. As a result of the expansion of the Munich Exhibition Centre to include two new halls, which will be available for opti 2019, the 2017 schedule must be moved by one day and will take place on Saturday, Sunday and Monday — from January 28-30, 2017.

THE WORLD OPTICAL MARKET IN 2016 – Part Two Richard Chaffin, Consultant Editor

T

he world optical market 2016 - part two will discuss the last five of the top ten country optical markets in the world. Those countries are France, Indonesia, United Kingdom, Italy and Mexico. What is it about these five countries that determines they are leading optical markets worldwide? Each country has been given a ranking according to the number of optical buyers. Who are optical buyers? Optical buyers are the people in need of eyewear and have the financial means, personal or government, to purchase eyewear (‘ability to buy’). The number of eyewear buyers has been determined by using a proprietary computer formulation combining many individual factors. In addition, knowing who the buyers are is as important as their total number. To analyse whom the buyers are you need to know their gender, male or female, age of the population, and also their disposable (more than food and shelter) income. However, each one of these factors must be further broken down. Gender may involve the eye skill required for male or female occupations. Age of the population has an important bearing on eyewear needs. Most people need vision correction, in general, at middle age (40) as their power of accommodation diminishes. They will be single vision wearers, reading, distance, or both. If presbyops they are multifocal or potential progressive lens wearers. Certain ethnic groups (countries) have more vision correction needs than others. The economic factor of whether a coun-

10

www.optical-world.co.uk

try has a developed economy and is rich, or underdeveloped and poor, is to be considered. All of the above are important. Also of interest when analysing a country’s optical market is its future, its growth factor. There are three elements to a country’s growth factor; the age of eyewear buyers, whether or not the population is growing or decreasing, and the changes in economic conditions.

France

France is the home of the largest lens company in the world, Essilor. France is also the place that progressive lenses originated as we know them today. The eyewear market in France is approximately 41 million buyers. Those that need eyewear are able to buy 100 per cent. France’s total population is more than 60 million people or close to 15 per cent of Eastern Europe. France ranks between eight and ten among the 109 countries studied for the total number of eyewear buyers. It has a strong number of ‘High End Buyers’. Progressive lens buyers make up 46.4 per cent of the potential market and are 19.35 million people. Market growth in France is due primarily to its aging population.

Indonesia

Indonesia is a country of more than 250 million people. The eyewear market is growing at a rate that is third largest in the world. The number of eyewear


buyers in Indonesia is 41 million. However that is only 25 to 30 per cent of those needing eyewear. There are no ‘High End Buyers’ in Indonesia. Therefore the amount of progressive lens and contact lens buyers is a small percentage. Indonesia’s rapid eyewear growth is due mainly to its economic growth, slight population growth, and aging population. The business environment in Indonesia ranks in the lower third of the world’s countries.

United Kingdom

The UK, a country that in the past had eyewear provided by the government, is a country where those needing eyewear have the ability to buy 100 per cent. The number of eyewear buyers in the UK is nearly 40 million. The ‘High End Buyers’ are approximately 13 million. The HEB is the fourth largest in the world. The UK has an aging population older than the world average. It is a very stable market for eyewear that was dominated by ‘multiples’, companies with countrywide outlets. The UK has the 10th largest number of eyewear buyers in the world. Growth in the market is due almost equally between economics, population growth, and aging.

Italy

Italy is the 6th most profitable eyewear market in the world. Italian frame companies dominate the world as well as the Italian optical market. Luxottica is not only a frame company but also the owner of Lenscrafters in the US, Oakley sunglasses, and Sunglass Huts worldwide. There are 40 million eyewear buyers in Italy, a number that has not changed for more than a decade. The number of people able to buy eyewear is 100 per cent. ‘High End Buyers’ in Italy are a strong area of growth numbering more than 10 million. The upper income groups have fueled the HEB growth. There are approximately 10 million buyers of progressive lenses or 49 per cent of the potential market. The progressive lens market is the 6th largest in the world. Aging of the population will be the key growth factor in Italy. Italy’s total population has been declining at a rate close to 5 per cent.

Mexico

Mexico is a country of more than 120 million people of which nearly 65 million need eyewear but only 40 million are able to buy. In spite of that, Mexico has become the 8th largest market for eyewear in the world. Mexico ranks 16th in the world for progressive lens buyers. ‘High End Buyers’ are only 3 million. The low-end income groups dominate the eyewear

market. Mexico’s economic growth will be the major factor in the future of the eyewear market. Aging and the population growth will also have some part to play in the market.

The Top Ten

An analysis of the top ten countries, their facts and figures, is certainly helpful when making decisions as to what eyewear market or country would be the most advantageous for doing business. However, this analysis may not tell the whole story. Where will the market be next year, the next five years? What is the political climate? How will wars and immigration effect eyewear business? How will the economic conditions of each country move forward? In addition, there are two things of ultimate importance that cannot be forecast. Those two things are the effects of government and technology. Governmental controls, regulations, and interference are unpredictable. Countries may have national health. They may regulate manufacturing, pricing, or set standards and rules. Technology can change everything. Computers, medical research, social media can cause big changes in the optical business. Continuing advances in organic indices, the photochromic process and coating are technology examples. What will 2016 predict for the future of the top ten and the world of optics? The information presented here comes from “The World Market for Vision Correction 2005 – 2020” authored by Mike Schaus and Richard Chaffin.

Anti reflection coating Tony Jarratt, Technical Editor

T

he supply of coated lenses has now become an everyday occurrence with the process being applied to a large majority of spectacle lenses – particularly when they are produced from high index material. It should be noted that the word ‘coatings’ now covers a far wider range of applications than was previously the case. In the ophthalmic context, ‘coatings’ originally meant only anti-reflection coatings. However, we now have to consider: Hard coatings Anti-reflection coatings Tinted coatings (Mirror coatings) Hydrophobic coatings Sometimes these are supplied individually, but they are often applied to the lens surface in successive layers, or even in one continuous process. This type of ‘combined coating’ is now most evident when we are talking about hard and AR coating. Many coatings now combine the properties of a hard and anti-reflection coating, sometimes with the added advantage of a hydrophobic or clean coat final layer – commonly known as a ‘top coat’. AR coating and reflections AR-coating on lenses is used for two principal reasons - to improve both the optical performance and cosmetic appearance of the lens. These are to some extent the same thing – if we improve the optical performance of the lens, we are quite likely to improve its appearance. The prescriber/dispenser will probably consider the optical aspects of applying such a coating whilst the end user – the wearer – will see the effect from a 12

cosmetic point of view, a reduction in surface reflections which will enhance the cosmetic acceptability of the lenses, thus making them more attractive in wear. The wearer will not necessarily realise that the improved appearance also means that there will be fewer reflections and an increase in transmitted light, with the resultant improvement in contrast and visual acuity. Formation of reflections If we consider the lens and eye in combination, we can see that they have three external surfaces between them – front and back surfaces of the lens and the surface of the cornea. Using this model, it can be shown that four different types of reflections are formed, depending on conditions. These reflections are: 1. Frontal reflections. Some of the light incident on the front surface is reflected back towards an observer, therefore degrading the cosmetic appearance of the lens. An example of this type of reflection is that produced when a spectacle wearer is in front of a television camera, the very bright studio lights are reflected from the spectacle lenses, thus obscuring the wearer’s eyes behind the lenses. 2. Backward reflections. Some of the light from behind the wearer is reflected from the back lens surface onto the eye. This causes disturbing reflections, particularly in dusk conditions or when driving at night, e.g. where ambient light levels are low and there is a bright light source such as the headlights from a car behind the driver.


3. Internal reflections. Light is reflected between the two lens surfaces, internally. This can be caused by light from any direction. It is the cause of the multiple 'rings' seen around the edge of some high minus lenses.

can be conveniently converted into percentage loss at each surface:

4. Corneal reflections. Caused by light being reflected from the surface of the cornea and then interacting with the lens surfaces. The last three reflections cause ghost images and can lead to lowering of visual acuity, due to blurring and reduced contrast. They therefore diminish the optical performance of the lens. Reflection number one would appear to be only a cosmetic problem, as it results in difficulty for an observer due to the frontal reflections. However, it does reduce the amount of transmitted light, which in turn reduces the efficiency of the lens. Surface reflections The ability to reduce the loss of light, caused by these reflections, has become more and more important as the dispensing of high index lenses has shown continued growth. This is because the surface reflections increase along with an increase of the index of the material. This increase in surface reflectivity is solely a function of the material index and cannot be affected by material design or composition, as can the ν Value (or Abbe number) and material density / weight. The amount of light reflected from a lens surface is given by the formula:

sr =

n’ – n ²

[ ] n’ + n

where sr = surface reflectance n’ = refractive index of lens material n = refractive index of the substance in which the lens is immersed – for spectacles this is air and n = 1

From this formula, it can be seen that as the material index rises, i.e. [n’] becomes larger, [sr] will also increase. This means that the amount of surface reflection will rise. Using the above formula and some of the standard indices, which are widely available, we can calculate values for sr and these

As we have to consider a lens there will be light lost at both surfaces, but this is not double the figure lost at the first surface. If we take the incident light at the first surface as 100 per cent and considering the light loss for a glass of n=1.800, we have the following: Incident light % loss at 1st surface (8.163% of 100) light transmitted after first surface % loss at 2nd surface (8.163% of 91.837) Light transmitted through lens

100.000 –8.163 91.837 –7.497 84.340

or a total loss of 15.66 per cent – assuming a ‘clear’ lens material and reasonably thin lens, where there is little or no light loss due to absorption by the material itself. Extra thick lenses, or those with a tint, will exhibit a lower overall light transmittance. It is normally accepted that the light loss for CR39 and spectacle crown does not cause any real problem for the wearer – although ghost images can cause difficulty in certain conditions. However, we can see, from the table, that the reduction in transmitted light for the higher index materials does become increasingly large. A loss of much over 10 per cent, becomes questionable and over 12 or 13 per cent, would be considered unacceptable to most users. In fact, the higher figures shown in the table – 15 to 18 per cent reductions in transmitted light, are equivalent to the sorts of levels found in some cosmetic tints applied to many lenses. In addition to this high light loss, the appearance of reflections for the lens surfaces is disturbing to the wearer due to the higher level of reflectance, which means that ghost images etc. are more noticeable.

Table: Losses due to reflection for a range of materials

For these reasons, it is advisable to provide antireflection coating for all materials with an index over say 1.66 and they are a must for 1.8 and above. It is, of course, now normal for all major manufacturers to supply their high index and very high index lenses with an AR-coating as standard. How coatings work Reflections are caused by some of the incident light being reflected by the surfaces of the lens material, theoretically when the light does not strike the lens surface at right angles. This causes several types of reflection. If we interpose a transparent layer between the light striking the lens surface and that surface, we cause two reflections – the first from the surface of the layer and the second from the surface of the lens itself. If the thickness of the layer is made a quarter of a wavelength thick, the two reflected rays will be ‘out of phase’, by half a wavelength. This is because the ray, which is reflected from the lens surface, has to travel through the layer and then back again – i.e. twice the distance. As the two rays are out of phase by a half wavelength, they will be mutually destructive – i.e. they will eliminate each other, thus destroying the reflection. As this mutual destruction takes place for one wavelength, the resulting reduction in reflections will not be complete. To overcome this problem, multi-layer AR coatings were introduced – these are far more effective, eliminating reflections over

14

a much wider range of the spectrum. Final transmissions of up to about 99.5 per cent can be achieved. Manufacture AR Coatings, initially introduced only for high index glass materials, can now be supplied to virtually all ophthalmic lens materials, both mineral and organic. Traditionally the method of applying an AR coating has been by vacuum deposition and this technique has been used since its introduction by Zeiss in the 1930's - initially for optical systems, but subsequently (in the mid 1950's) for high index glass spectacle lenses. However, there are now several variations on the original concept and the process can now be classified into the following methods. Most depend on the deposition on the lens surface of one or more alternating low and high refractive index layers of metal oxides. (Note: the following descriptions give a general idea of the coating processes involved – they are not intended to be definitive – but only to act as a guide. Different variations of the processes are available – according to the particular requirements of the end user and the equipment available). 1. The original evaporation process: Under this process, the lenses are placed in a chamber, which is capable of having the air evacuated to a very low pressure – thus producing a


high vacuum. The chamber and the material to be used for the coating layer(s) are then heated – in the case of the coating chemicals, to a very high temperature. This causes the chemicals to vaporise into a gaseous state. At the same time the lens surface is charged electrically, with respect to the remainder of the chamber. As the chamber is at a high vacuum, the gas molecules can travel directly from the heating element onto the lens surface, being attracted to this by the electrically charged differential between the lens and chamber. To achieve these results, the earlier coating machines had to achieve a very high temperature, in order to evaporate the chemicals. This temperature would have damaged the plastics lens materials. However, a new method was introduced which overcame this problem. 2. 2nd variation – using an Electron beam gun: These machines use a different method of evaporation. This is achieved by means of an electron beam gun, which fires a charged beam at the chemicals, achieving evaporation at a much lower temperature. This, coupled, with the use of sophisticated microprocessor control of pressure, temperature and evaporation rate, has enabled manufacturers to produce machines which can deposit single and multi-layer coatings on virtually any lens material. 3. Magnetron Sputtering: A third method of deposition is that of sputtering. In this process the material to be deposited (in the form of a fixed target within the vacuum coating chamber) is eroded by energised particles (normally positive ions) striking its surface – the rate at which this takes place being controlled by magnetic fields produced by magnetrons within the chamber. The resultant material ejected from the target, being deposited on the lens surfaces. Again, this method can be carried out at a much lower temperature, making the process suitable for all types of lens substrate. 4. Plasma polymerisation: Polymerisation is basically a chemical reaction where molecules (the monomers) are joined to16

www.optical-world.co.uk

gether to form the polymer, which then consists of large repeated chains of molecules. Plasma polymerisation is a process where the chemicals are evaporated into a gaseous state (gas-phase monomers) within the vacuum chamber and are then assisted by the plasma into forming a polymer, which is deposited onto the substrate surface. This type of process is used, for example, to deposit the ‘hydrophobic’ coatings as the top layer of an AR coated lens. Other considerations The following two pieces of information are supplied courtesy of Satisloh and is taken from their coating process guide. Top coating options. Ease-of-care is perhaps the most important feature of AR coated lenses to the average customer. A naked AR coating is by nature rough and hydrophilic, meaning it will attract dirt and water and will be difficult to clean. Making the problem even worse is the fact that an AR coated lens will show the dirt more than a non-AR coated lens. Fortunately, coating technology has advanced rapidly and there are a number of new chemical options available to make AR coating easier to clean than ever before. These chemicals are applied on top of AR (hence the term ‘top coating’) inside of a vacuum chamber. Hydrophobic vs. oleophobic. When the first easy care top coatings were introduced back in the late 1980’s, they were loosely referred to as hydrophobic top coatings. Hydrophobic literally means ‘waterrepellent’ and the quality of a hydrophobic top coating has traditionally been measured by the contact angle of a drop of water on a lens. A higher contact angle (roundness of the drop of water) equates to a better hydrophobicity. Traditional hydrophobics typically have contact angles in the range of 97-104 degrees. The newest generation of hydrophobic top coatings, referred to as super hydrophobics, have a contact angle in the range of 106-112 degrees. More important than its ability to repel water is a super hydrophobic’s ability to repel oil and fingerprints, referred to as oleophobicity.

In collaboration with their partner Druschke their remanufacturing upgrade programme greatly extends the life of PFC00 and 01 series systems and greatly improves the performance and reliability of current generation MaxCool and PFC02 series units. A Stratox remanufactured and upgraded unit performs better and costs around half the price. Polycold systems are well regarded as tough reliable units. Sticking valves and blocked capillary lines have been designed out of the remanufactured units. Higher performance than the OEM is achieved through improved oil handling and a unique high efficiency gas Cascade refrigerant blend, environmentally safer, with reduced power consumption and low global warming – so much so that the twice per year inspection requirement under F-Gas is reduced to a single annual check. Remanufacturing not only saves money but makes environmental sense, so confident in their German factories quality that they offer a 12-month warranty when installed by a Stratox channel approved installer.
