The most common mistakes when using contact lenses

The most common mistakes when using contact lenses
1. I do not need a doctor’s consultation, I can choose the lens itself.
The desire to save – this is quite natural, but if you choose to wear contact lenses, you should understand and accept the fact that your costs will include not only the cost of contact lenses, but the cost of medical services.Hike to the doctor before you buy new contact lenses – a prerequisite, contact lenses are medical supplies. Saving for a doctor, an ophthalmologist, you risk to get not match your vision, or the size of the eye lens.In the best case, you lose the money spent on the purchase of lenses, at worst, be harmful to your health. Therefore, for the purchase of contact lenses, you should contact the office contact correction.Physician ophthalmologist should check your vision, measure the required parameters and examine your eyes using biomicroscopy, discuss with you the possible mode of wearing and replacement lenses, listen to your wishes.If necessary, conduct additional studies – measurement of accommodation and keratinocytes, topography, and so on. Then undergo a procedure to try on selected lenses.Now, already in the lenses you once your eyes tested, viewed under biomicroscopy to ensure that the selected lenses come in size. And you will be able to assess whether they are convenient and comfortable. Only after this the doctor writes a prescription for contact lenses,which necessarily includes: 1.Name (brand) Lens 2. The optical force 3.Size (base curvature) Your doctor also needs to find you a most suitable tool for lens care and teach all the rules of use of contact lenses / No less important, and further medical care for the entire term of use of contact lenses.Usually, the doctor invites up visits 1-2 times a year. This will allow you to avoid potential problems and time to make adjustments, especially if your vision changes or you want to try something new.If you already wear lenses and decided to try other medical consultation is also needed. Even with their views on what lens you fit best, is to discuss the matter with the specialist.Perhaps you are right and the doctor agree with your decision, and perhaps not, and then the doctor will explain what you’re mistaken. To purchase new lenses also need to try on (even if all parameters match). Only after inspection and verification of a physician may prescribe a new prescription.
2.Contact lenses can be prescribed for longer term wear.
Often we hear from patients – “I change lenses a little later, when I feel that they are beginning to disturb me …” Unfortunately, this approach is fundamentally flawed.Contact lenses should be comfortable, and stable vision, for the duration of their use. Therefore, there were modern planned replacement lenses. Their task is to nullify the negative effects on the eye accumulate on the lens surface deposits.If the lenses begin to interfere, then the time of replacement lenses have expired. Please do not forget to replace the lens, and if you noticed that a comfortable period of wearing lenses is less than the recommended period of change, notify your ophthalmologist.
3.Courting lenses are not necessarily enough to omit them for the night in the solution.
If you use reusable lenses, the service life of which no more than 1 month, suitable daily care by a multifunctional solution (when the lens is washed in a solution at the palm).For quarterly replacement lenses and traditional need additional weekly cleaning with enzyme cleaner. Completely get rid of care, you can use disposable lenses.
4.Contact lenses can be worn at night.
Another common mistake – sleep in the lenses, not intended for this. The level of oxygen permeability of lenses are categorized as lenses for daily wear (they must be sure to remove before sleep), flexible (they can sometimes leave for the night), and prolonged or continuous wear (they can sleep up to a few nights in a row).I must say that even modern well-oxygen leaking silicone hydrogel contact lenses are not allowed to reduce the risk of microbial keratitis in prolonged wear.That is why doctors so frowned upon the manufacturer that some lenses can be worn up to 30 days without taking off. When buying lenses be sure to ask your doctor whether you can sleep in your lenses.
5.I’m okay and I do not necessarily go to the doctor.
Even if you are sure you have everything in order, you must visit the ophthalmologist 1-2 times a year (if your doctor does not prescribe more frequent mode).Regular inspection is necessary to monitor your visionstate of the eyes and contact lenses. Early signs and changes in the eye may not be noticeable to the patient and found only at the examination. In time the adjustments will help avoid problems. We wish you health and an excellent view!

Who is not recommended to wear glasses with high refractive lenses

Who is not recommended to wear glasses with high refractive lenses:
As sales grow lenses of materials with high refractive index, some experts in the field of optical correction of vision expressed the view that designate these lenses should not everyone.Consider the case where the choice of high-refractive lenses are not recommended
You ametropia less than 2.5 diopters.
In this case, it is difficult to notice and appreciate such advantages of high-refractive lenses, the smaller weight and thickness, especially when building a frame with small sizes of skylights.At the same time, the choice of an aspherical lens and a-toric designs in small refractions can be fully justified, since these designs offer significant optical advantages,reducing the astigmatic error in the peripheral zones of lenses.
Selecting glasses with the design without rim.
Care should be taken when performing such an order at a complete set of his high-refractive lenses.If a company – the manufacturer of lenses does not mention that the high-refractive material data elements recommended for glasses with no rim, it is best to choose, for example, lenses made of polycarbonate, which have high impact resistance.
When transferring the look you prefer to roll their eyes and not his head.
These customers will be more sensitive to the appearance of chromatic aberration when you look through the peripheral zone lenses.Fortunately, people with a high degree of refractive error, and which are most suitable candidates for appointment to the high-refractive lenses, typically refer to those when examining any object larger rotates his head.
Building on a rim of different lenses.
When working with high-refractive lens assembly in a single frame lenses with different values of the refractive index is unacceptable, even if you follow the intentions align the thickness of lenses ordered during refractive error and therefore are looking for a lens with a lower optical power of the material with n_d = 1,50,and for greater refractive lens – with n_d = 1,0.In such glasses the client will feel discomfort.
Adjacent frame.
High curvature inherent in these frames, difficult to reconcile with a more flat surfaces of highly refractive lens, and as a result of ready-glasses will have no aesthetic appearance.

Improving appearance of points of high-refractive lenses

Highly-refractive lenses made of organic materials can significantly improve the appearance of spectacles.Using the lenses of materials with refractive indices from 1.60 to 1.74 can substantially reduce the thickness and weight of lenses and glasses to make a superficially more attractive, even at high degrees of ametropia.The variety range of high-refractive lenses in combination with optical coatings, which offer today, many manufacturers, often puts consumers in a quandary: what lens to choose?To make the right decision, we must understand the basic characteristics and features of the lens material with high and superhigh refractive index.

Key Features and Benefits:
Refractive!
This characteristic shows the relationship between the speed of light in vacuum and the speed of its spread in this material. Obtained by dividing these two parameters, the number (eg, 1,5, 1,6, 1,67, 1,74) and is the refractive index (n_d).The larger the numerical value, the greater the slowing down or rejected in the material world.This means that highly refractive organic material reject transmitted light at large angles than the standard plastic with n_d = 1,50, and hence the lenses of these materials requires less curvature of the surface to ensure the same optical power,like the standard plastic lenses.Thus, the lens of material with n_d = 1,67 will be much thinner than a standard lens with organic n_d = 1,50 the same refraction.Highly-refractive lenses have a flat surface than a standard plastic lens, and the combination with aspherical design has further thinning and flattening of the lenses of both positive and negative refraction.Such lenses are well suited for assembly in the popular frame of small geometric dimensions with a low angle of the bend.At the same time to build the adjacent frames with a higher surface curvature is necessary to use a special lens design that have already appeared in the range of producers.A number of high-refractive materials, such as n_d = 1,67, characterized by high physical and mechanical characteristics, which makes lenses based on them suitable for assembly in glasses with lens mount with screws.
Number Abbe!
If you look at the high-refractive lens is not through the optical center, and a remote area of it, it will become visible color components that make up white light radiation.These components are distributed differently, depending on the wavelength, which can lead to a deterioration in the quality image of the object as seen through the lens.This effect is called chromatic aberration, and from time to time, users complain of her points (describing the halo or colored rim around the edges of the object). The main task of the developers of lenses is to minimize chromatic aberration.The quantitative parameter used to determine the chromatic aberration of the optical material, called the Abbe number. The lower the value of this number (see table), the more noticeable chromatic aberration, and the greater its value means that reduction.In the optical center of lens chromatic aberration of the least visible and well-tolerated. Its effect may also be reduced by minimizing the lens decentration and the use of frames with the small size of optical apertures.During the assembly points should strive to ensure that the optical center with the best optical properties are located directly opposite the pupil, and try to reduce those areas of the lens, in which the effect of the expansion of colors more visible.
Properties of anti-reflective coatings!
Physical methods completely eliminate the phenomenon of chromatic aberration does not exist, but according to experts, drawing anti-reflective coatings improves the portability of glass lenses with small values of Abbe and is mandatory for lenses of highly refractive materials.After all, these lenses have a more compact structure and reflect more light than traditional lenses of materials with n_d = 1,50.The higher the number of reflected light from both surfaces causes the formation of interfering light, even under normal lighting conditions and creates an annoying ghosting when there are multiple light sources or made sources of bright light in a relatively dark environment(candles in the darkened restaurant,lights of the oncoming car while driving at night, etc.). Application of high-quality anti-reflective coatings can dramatically reduce the amount of reflected light and provides improved optical lenses and of their appearance.
UV protection!
The chemical structure of highly refractive lens helps cut damaging ultraviolet (UV) radiation, while the standard plastic lenses require special methods of modification, such as application of UV-absorbing coating or treatment in a solution of UV-absorbers,that can lead to visually appreciable yellowing.

Sun lenses for balloonists

During the flight, the balloonists will wear quality sunglasses that provide complete protection from ultraviolet radiation up to 400 nm. In addition, ideally, these glasses, especially if you use their pilots flying non-motorized means, who have in-flight monitor changing weather by the movement of air currents, should provide a sharpness and contrast,what can not guarantee normal “solar” glasses. A new generation of sun protection lenses on the market today that fully meets these high standards. For many athletes the ideal solution became sun lenses Skylet from the company Carl Zeiss Vision. They are, for example, uses the national team in Germany for gliding. Name of the lenses – a marketing gag Manufacturer: after «sky» in translation from English means “sky” and, consequently, these lenses will attract the attention of those involved in air sports. Thanks to their optical properties of the lens Skylet filter the visible portion of the spectrum and reduce the degree of abstraction of the image. In manufacturing lenses using a special filter that effectively reduces the light transmission shortwave blue radiation of a wavelength of 400-500 nm. Partial excision of this component of the solar spectrum contributes to reducing shine and reduce eye strain without changing the natural color perception of objects of the environment. At the same time, if the blue light filter completely, some colors will be impossible to distinguish. Aalenskogo University Professors Bernd Lingelbach and Hans Obermayer tested the pilots filter that absorbs the blue component of sunlight wavelength 550 nm. It was found that as a result of drivers stopped to recognize the blue and slightly different green. Difficulties have arisen not only with color vision, but also with the ability to navigate. Thus, a safe amount of blue light must reach the user’s eyes.Lens with image contrast due to absorption of the blue component of sunlight, are present in the collections of such leading manufacturers as Rodenstock (lens brand SunContrast), Rupp und Hubrach (lens brand Brillant), Essilor International (lens brand Extrem).

Requirements for the glasses to practice air sports

During the flight, gliders and gliders are observed for the landmarks, and the clouds, and the instruments, and other pilots, and hence, their glasses should provide a wide field of view, including peripherals. A good solution in this case could be glasses Elevation from Adidas, which not only meets the above requirement, but also equipped with a proprietary company LST-filters, allowing to balance the change in illumination, while preserving image contrast.For pilots it is also important because they often fly in the bright sun, and sit in a shaded valley.In addition, it is good when glasses gliders have the reinforced protection of the nose, as if a hard landing “at three glasses (on the nose and a trapeze apparatus) met face an athlete to land is often inevitable. As paratroopers, even in their case, providing a wide field of view glasses is required: during the free fall they have to look up as controlling the disclosure of a parachute, and down when landing. If the skylights glasses are too narrow, paratrooper will be forced to watch, then lowering, then raising his head. As a result, it can lead to a change in the position of his body, which is fraught with dangerous consequences.The best option in this case are tight-fitting goggles to face-mask. Judging by the discussions on Internet forums, fans of air sports, not uncommon problem that they face is fogging lenses in spectacles.Due to lack of information, most athletes and still remain in full confidence that nothing can be done about this, few are aware of the existence of special sprays and wipes, preventing fogging of lenses Meanwhile, manufacturers of sports glasses quite successfully fight this problem.The main way to prevent fogging include improved ventilation system, an example of which is a patented ventilation system lenses Adidas ClimaCool, which is a system of ducting that runs along the inner edge of frame glasses,so that the counter flows of air are distributed in such a waythat the possibility of fogging lenses excluded; the use of active ventilation systems (in particular, using microelectronic fan) drawing hydrophilic coating on the inner side of the lens; availability fuser – a layer of air between the filters, which smooths fluctuations.And another important point: the glasses should be made of shockproof material, as an unsuccessful landing parachuter – for example, in the crown of trees – occur quite frequently. Logical to try on glasses with the helmet, which is a mandatory part of the outfit parachutist.Pilots same engine aircraft, using radio communication, is to bring along an optical Salon headset, which they wear during the flight, because you have to remember that a lot of pressure on the ear hook earphone glasses can cause very unpleasant sensations and even pain.

I see everything from above, you may as well know

For those involved in air sports, good vision is important from the standpoint not only of comfort, although it is important, but sometimes even basic security. Judge for yourself.To plant a glider, the pilot must be from a height of more than 200 meters to set the wind direction on wind indicator at the airfield, often quite faded and rather shabby, and therefore a great risk to go unnoticed.There are, however, and other proven methods of determining wind direction: the smoke from the chimneys, the movement of waves and ripples on the water bodies, etc. However, they presuppose the existence of sharp vision at the balloonist.Those who can not boast of such, to avoid unpleasant situations is to think about the means of its correction, namely, the glasses or contact lenses. Wearing corrective glasses during the flight, in principle, is not forbidden.In order to ensure their retention in high winds, many athletes wear over corrective glasses, plastic glasses parachute. They are mounted on the head with straps. In some Aeroclub such goggles can be rented.However, although this is a solution to the problem of preservation of corrective glasses, it is preferable to use in-flight special sports glasses, combining the protective properties and the possibility of vision correction,carried out by insertion of prescription lenses or the use of corrective clips.As for contact lenses, many users put on them during the flight, noting the following advantages compared to the last glasses: a more natural vision, full field of vision, lack of sweating, lack of moisture condensation, the absence of discomfort and feelings of irritation,caused by the weight of frame,absence of reflections from lens surfaces.Nevertheless Airborne recommended over contact lenses still wear tight-fitting goggles which will protect their eyes, not only from ultraviolet radiation, but also from the air flow reaching the high altitude very high speeds.

Glasses for aviators

At the beginning of XX century glasses were part of equipping airmen. Nothing was for the pioneers of aviation as important as good eyesight, and nothing is promised a bigger threat than in my eye pilot foreign body. And if the car is the beginning of XX century it was still possible in an emergency stop with my eyes closed, then the pilot’s loss was fraught with opportunities to see the plane crashing, but because good glasses are no less important for the flight than the fuel tank. On the aesthetic component of these glasses initially there was no question: the main thing that they have been reliable and functional, that is, protect the eyes from cold, glare, and even boiling water – if the sudden burst radiator.With the advent of closed cabins weather could no longer be afraid, and the main function of the Glasses was to ensure the pilot eyesight and eliminate the blinding effects of sunlight. In 1930 the company Bausch & Lomb, founded in 1853 by German immigrants John Jacob Bausch and Henry Lomb, launches in New York full-scale production of sun lenses based on lens Umbral firm Schott, and in 1934, saw the light of glasses brand Ray-Ban with green lenses dropsbecome an attribute of American pilots. (Literally, the brand name can be translated as “protection from the rays,” “obstruction to the passage of light.”) These Glasses were not created for the sake of fashion. Their form, is still relevant today, and was dictated solely anatomy of the human person.They provide maximum field of vision and thus missed a minimum of scattered light. It was a form arising from the function, aesthetics appropriate, familiar to us and the aviation wrist watch, which is another working tool of a pilot in the cockpit.Along with the development of technologies emerged and new solutions Glasses to a good showing and on the ground and in the air, and even on board the spacecraft. This is a collection of frames and sunglasses Titan Minimal Art.The new software used technology, resulting from the joint work of the Austrian company Silhouette and Space Research Center NASA.Manufactured since 1999, and weighing just 1.8 g, titanium glasses Titan Minimal Art withstand extreme loads experienced by astronauts during the flight.Speaking of glasses for pilots, would also note the line of Lufthansa, developed by Rodenstock with the participation of experts of Lufthansa.To create Glasses of this line is used titanium and trogamid – material relating to the group of polyamides and having a high degree of flexibility and strength. Lenses made from polycarbonate and are coated. Glasses this line are compatible with oxygen masks.

Ecology and advertising

Because, as you know, trade is the engine advertising, presence in it of environmental topics has become common.The recent campaign to promote a new collection of glasses and frames trademark Oxydo, manufactured by the Italian company Safilo, – a living example. Characters posters, boy and two girls, are depicted as “super heroes”, seen from space our planet (of course, through the glasses Oxydo) and finished at the right time to come to her aid. The environmental focus of advertising, which have been made in the company management, and emphasized the slogan “Defend the world» (Protect the world). It is often environmental advertising does not conform with the specifications of goods sold.Thus, at the Paris exhibition SILMO-2008, many visitors drew attention to the stand, a Spanish company Etnia Barcelona SLEyeglasses company (made from traditional metal and plastic) are not shown in conventional windows, and wooden crates of fruits and vegetables, to emphasize the connection of these products with nature and their useful properties. This in no way reduces the dignity of a very interesting collection of Spanish manufacturers with bright and original models, named after the cities of the world (incidentally, note that one of the models is called «Kiev»).At the end of 2008 on the French sites are widely discussed advertising glasses Ushuaia, distributed through one of the largest local optical networks Atol. In its creation participated known model Adriana Karembeu. The problem is that the French word «Ushuaia» is logically connected not with the capital of the archipelago of Tierra del Fuego, and on the cult television program, which in 1980-90-ies conducted Nicolas Hulot, founder and former director Green Party. The program was devoted to the reserved places on our planet and had a distinct environmental focus. That’s why many of the French use of the proper name in advertising the product, unrelated to the “environmental” goods, caused confusion. So, we have completed a brief digression on the various ways of solving environmental problems in the optical industry. Judging by the publications in the optical media and in the optical Internet, today this problem is not too worried about the large number of producers and certainly very few opticians.But if the fashion for all environmental strengthen their positions and take in the minds of consumers is the same strong position as, for example, the idea of the dangers of smoking, the methods discussed in the paper ecological and ethical approach to the production, sale and use of points will be introduced everywhere. And sooner or later reach and to our country, although at the moment our environmental consciousness is still far from the only Canadian, but even from the European average.

Coverage of environmental issues at SILMO

It is guided by the criteria of long-term development of the international jury of optical SILMO salon in Paris in the awarding of those enterprises that adhere to the above principles in management, development of the product concept and the choice of materials. Special Prize was awarded to German company OBE, which is widely known in the market for optical components products. Being under the banner of ecology, is a company for 12 years has achieved remarkable results, reducing the amount of energy consumed by 33%, and water – by 59%. Optimizing the use of raw materials could reduce its volume by 35%. Significantly reduced waste production – by 62%. The company has installed special equipment to clean water, and steel wool is sorted and sold metallurgical plants for further use. It was noted and the activities of the French family-owned business Julbo. The company, operating in the optical market 120 years, is known for its sensible pragmatic approach to business. The production of frames for two-thirds carried out in Europe, it helps to minimize transportation costs. Carton, before going for recycling, used an average of six times. Designed and implemented a special program saving natural resources and limiting consumption of energy.Thus, the plant of the company, located in Romania, is heated due to the presence of geothermal springs.To reduce the movement of workers in their own cars, from the 1980′s Directorate of the French plant to be carried on work on machines that are used to transport goods, but can easily be transformed into a passenger transport. Special mention in the category of products that meet the principles of sustainable development, awarded by SILMO collection of frames Tornado, produced under the brand Derapage (owned by Italian company Nico).One feature of these frames is that they are made of three steel strips that are fastened with no welds, rivets, micro-technology, similar to what is used in precision technology and jewelry. Technological process patented.Frames are light, high strength,innovative design and enjoyed a deserved success at the show. This collection was also awarded in Japan (Eyewear of the Year 2008) and in the USA (Good Design Award) and nominated for a prestigious design awards Designpreis (2009) in Germany. An ecological approach to producing and selling points ** The development of “environmental” rims are on two fronts: the creation of frames from materials that can be recycled, or from those who, after completion of the life of the rapidly biodegradable. The first group can be attributed rims SKGreen company Linkskin, represented in Europe, the French group L’Amy. First aired in spring 2008 at the Salon MIDO in Milan, these models are immediately attracted the attention of specialists. They also were noted and the jury SILMO-2008.A special feature of this product is that it is made from recycled materials, which can be used in the future. Frame and Temples are made of injection plastic and are mounted on a strip of medical steel with a patented system of clips, without hinges and screws.In addition, the production of frames are not used welding processes. Weight frame does not exceed 10, all stages of life cycle of product conceived so that its impact on the environment was minimal. Incidentally, this applies not only to the frames, and casings (made of polymer materials), packaging (cardboard, chlorine-free), and even advertising of equipment for optical shops. Optics are encouraged to collect end-of-products and send them to the company for recycling.These frames were commended environmentalists. It should be noted that attempts to frame this kind have been undertaken in different countries with varying degrees of success.So, back in 2003 the French company BAB-Webs has developed a project to produce frames of the material to be recycled. The project was the use of vegetable fibers (sisal, hemp, wheat straw).The company announced the creation of “environmental” rims in 2005 and expressed its intention to develop by 2010 a barrel of a fully biodegradable materials.Trial sales were made on the Internet, but the further development of the project, apparently, did not receive, because mention of it in the press stopped.ICU Eyewear American company in 2007 introduced to the market his collection of sunglasses, where the frames are made of metal and plastic, which can be used again. A year later appeared in its portfolio model, where the Temples are made of bamboo.Because bamboo is a plant, whose reserves are replenished quickly, without significant harm to the environment, the company has every right to sell their products under a bold advertising slogan: “From now on, your vision and your conscience will be equally clear.”Went even further American company Kayu, recently appeared on the market of ecological optics. Its creator Jamie Lim (Jamie Lim) has developed a line of sunglasses, eyeglass frames which are completely constructed from bamboo.Elegant hand-made glasses with wide skylights are sold at a price of $ 180, 50 of which are directed to the needs of charitable organizations. Do not remain aloof from the environmental problems and the owners of optical stores.For example, Singapore’s Nanyang network announced in late 2008, which completely goes on sale “environmental” frames and glasses (including products Linkskin).Interior design shopping network has changed radically: their design is now used green plants, and the floor is a bamboo cover. In addition, Nanyang organize a system for collecting old glasses and lenses in order to further processing.As a curiosity worth mentioning the initiative of some environmental groups who claim that humanity can and must completely abandon corrective glasses, turning for assistance to known and we have plastic “mesh” of points.It is believed that the wearing of data points leads to complete vision correction that is not supported by medical research.

Frames from natural raw materials

What we wear? What we eat? How does the air we breathe? What will come after us on the planet? These issues have long been given mankind. Without a doubt, the interest in the problems of protecting and preserving the environment concerns and areas of optical products.The second half of XX century was a watershed period in regard to issues related to the environment. Rapid population growth, the development of new technologies in the industry, thoughtless use of chemicals in agriculture have led to the fact that the environment has deteriorated due to water pollution, air, soil and climatic conditions that have changed. Of course, it could not leave indifferent those citizens of the Earth, which is inherent anxiety about the fate of the planet and future generations. That is, and has promoted environmental – has existed since the XIX century the science of the relationship between an organism and the environment – from highly technical subjects to the forefront of modern research and drew attention to her public. There was a even a branch of it as a video-ecology, which studies human interaction with the visible environment, which implies that everything we see is also an environmental factor.Eyeglasses from natural raw Ecology became fashionable topic, since interest in the quality of living conditions peculiar to everyone.But this interest was originally wore a selfish character: the planet’s inhabitants, especially the industrialized countries (which, incidentally, contribute most to environmental pollution), more worried about the impact of environmental factors on their health and standard of comfort.People realized that around them there are many items made from harmful materials.It was on this wave, and there were so-called green products or organic products – created from natural materials without the addition of synthetic substances or the production of which is not used hazardous chemicals. This trend is manifested in optics.There are a number of manufacturers specializing in the creation of frames, or some of their elements from natural materials. The use of wood, leather, horn, tortoise shell became trend phenomenon, and products in which these materials are involved,most highly in demand among buyers.At the same time you make a reservation, that the rim of natural materials usually relate to higher price range than metal or plastic models.This is explained by the fact that they are mostly made with the use of manual labor that requires high skills, and each of these frames is the only of its kind. This fact naturally carries similar products in the category of luxury goods, not available to every consumer.Publications in the media allowed us to do and one very paradoxical observation. Environmentally-minded public has long opposed the use of such materials of animal origin, as natural fur and leather.Recently added to the list horn and tortoise shell. In fairness, we note that extraction of the latter is already banned, and manufacturers of frames using old stocks, which also contributes to higher prices of their products.Many companies indicate in their promotional materials as an environmentally friendly, and such material as cellulose acetate, as it is created on the basis of natural cellulose, but it is still possible example of a successful marketing tactic than the testimony of caring for the environment.In keeping with this environmental fight interesting trends emerged.The German firm Grotesque as a bargaining chip of its advertising campaign uses the very fact that, unlike other firms operating in high-end segment, in the production of frames, it does not apply any horn or skin.Environmental Responsibility According to scientists, environmentalists, not the presence of natural materials determines the ecological purity of a product.In a number of environmental criteria include the use in the production of such materials, which can recycling and reuse, the introduction of manufacturing processes and technologies that conserve energy and not polluting the environment.This means that in the minds of people, goods consumers and businessmen should enshrine the principle of the broader notion of ecology, which includes not only care about the comfort of the buyer, but take action against the worsening living conditions on the planet.Many environmentalists also favor a more balanced policy of awarding one or the other so-called green product brands such as Green Label, Grune Punkt, etc., as often such labeling indicates only the environmentally friendly packaging, rather than the product itself.In Canada, a rating of “environmental responsibility” of producers engaged in a specially created Inter-University Centre for Studies of the life cycle of products, production processes and services (Interuniversity Research Centre for the Life Cycle of Products, Processes and Services – CIRAIG),, which brought together 20 professors and 80 researchers.Considering the example of ordinary corrective glasses, head of the Centre Professor Rejean Samson rightly says that before they reach the consumer, these points pass through the hands of the designer, manufacturer, seller, optics, and an optometrist. Lifetime frame is not very long, and eventually it will complete its existence in the garbage bin. Therefore, according to Professor Sampson, you need to take a responsible approach to work with raw and other materials at every step of the way of goods to the buyer.The manufacturer must impartially evaluate the impact of their product on the environment and ask yourself some questions: whether the use of this material is not whether to reduce the size of lenses, etc.Professor Samson believes that, firstly, this approach will significantly reduce production costs, particularly to reduce energy costs, and secondly, it will contribute to long-term development strategy, which involves both economicsand the environment and society.Among the enterprises of the optical industry, is actively collaborating with the center, occupies a prominent place the company Johnson & Johnson. On the relationship between fashion and ecology and said at the conference «Eco-Ethical fashion: is it just a fashion?», Held in Florence April 15, 2009.Participants talked about how serious fashion, as a global process, can have an impact on changing attitudes towards environmental issues. The conference received attention and fashion accessories, including glasses.
