Laboratory for the production of rigid conventional lenses. Hygiene and contraindications

Recently, contact lenses have become the main means of vision correction.

It’s understandable, it’s convenient, it provides a full view (and not cut off at the periphery like glasses), they don’t need to be adjusted (at least not as often as glasses), and generally lead an active lifestyle.

Year after year, lenses become more and more comfortable and safe, and lenses released just 10 years ago cannot be compared with what is produced now. But, as happens with any product of progress, we often do not know how they are produced. Let's briefly look at production methods, but for a better understanding of the technical process, let's look at the types of contact lenses that exist.

Types of contact lenses

In general, contact lenses are divided into two groups (according to the degree of hardness):

- Soft;
- Tough.

Hard contact lenses

Rigid lenses were invented back in 1888 (by Swiss ophthalmologist Adolf Fick, although drawings of nothing similar were found by Leonardo da Vinci, but the first “working” prototypes were created by Fick). They are used for vision correction in severe cases (such as astigmatism), as well as orthokeratology (changing the shape of the cornea using a special lens).

Due to their rigidity and shape, the use of these lenses can maximize visual acuity. The main disadvantage is that hard lenses are much more likely to cause eye irritation than soft ones.

Soft contact lenses

Soft lenses invented in 1960 (by Otto Wichterl and Dragoslav Lim, from Czechoslavakia), and since then 90% of contact lens owners on the planet have switched to them. They were called “soft” because of the main polymer in their composition. It has an unusual ability to absorb water (up to 38% of its weight) and when saturated it becomes very soft and elastic. Subsequently, this polymer was improved.

And now soft lenses are divided into 3 classes (based on the name of the polymer included in their composition):

— Hydrogel (invented in the 1970s);
— Silicone hydrogel (invented in 1999);
— Water-gradient (presented in 2016);

Silicone hydrogel lenses, in addition to their high elasticity, have become permeable to oxygen (although it would be more correct to say that the cornea receives the necessary oxygen through the liquid of the lens; in any case, this was a “breakthrough” for soft lenses).

Doesn't have its own blood vessels, and the supply of oxygen and nutrients comes from the marginal vascular network (in the case of oxygen, also partially from environment), which is located along the periphery of the cornea (in the so-called limbus region). And the main problem with lenses is the creation oxygen starvation cornea (in scientific terms - hypoxia), because the lens just covers the cornea, which does not receive the oxygen it needs in the right amount. Hypoxia stimulates the production of special substances, which in turn cause the growth of old and the appearance of new vessels, which will have to compensate for the lack of oxygen (neovascularization).

However, along with new vessels, dense fibrous tissue will grow on the cornea. It allows the body to heal damage faster. But this fibrous tissue is not transparent. And this can subsequently manifest itself as visual interference (an incomprehensible veil before the eyes), deterioration of vision (up to its complete loss). Therefore, doctors recommend that you be careful when choosing lenses, and even more so, they advise you not to leave them on overnight (this was one of the reasons that spurred the creation of daily lenses).

In other matters, silicone hydrogel lenses became the first lenses suitable for continuous use for quite a long time (from 7 days to 30 days), this is due to the slower evaporation of water from the surface of the lens, and the cornea remains moisturized longer.

The next step in the development of soft lenses was water-gradient lenses. The researchers set the task of combining the high permeability of the lens to oxygen and its high moisture content. And they succeeded. The moisture content of such lenses is 2-3 times higher than that of the best silicone hydrogel analogues, and the thickness is close to a record 80 micrometers (people who previously wore lenses of other types described that water-gradient lenses are almost not felt).

Methods for making contact lenses

The following production methods are currently used in the medical industry::

— Centrifugal molding;
— Turning;
— Casting;
— Pressing;

In addition to the above, production techniques are used that combine some of the above methods.

Centrifugal molding

The very first method of making soft lenses, invented by employees of the Institute of Macromolecular Chemistry in Prague in 1960 (in fact, like the soft lenses themselves). The method, however, is still used today. Its essence is simple, it lies in the fact that the required portion of liquid rotating at a certain speed gradually solidifies.

At the first stage, the liquid monomer is placed in a special mold (representing a cylinder with a concave bottom) which then begins to rotate. Under the influence of centrifugal forces, the liquid monomer spreads inside the mold. Due to the fact that there is a certain amount of monomer in the mold, it rotates at a certain speed and all this happens at a certain temperature, the monomer solidifies into in the required form(polymerizes, or simply turns into a solid polymer). Often faster hardening is achieved by using ultraviolet rays.

The hardened polymer preform is removed from the mold and hydrated. In short, this is the process of saturation with water (absorption) to the desired concentration. The main difficulty with hydration is that after hydration the dimensions of the lenses will be different than initially, so a preliminary calculation of the change in the geometric dimensions of the contact lens is carried out.

This is followed by computer photo control (size, shape, quality of polishing, etc.), after which the sterilization stage begins. During the sterilization process, the surface of the lenses is cleaned of all microorganisms that “settled” on the lens during the processing of the original polymer blank. Usually they also use ultraviolet radiation (occasionally microwave), but they can also use chemical substances(something based on hydrogen peroxide), or the old proven method - heat the lens to 120 degrees and wait a little.

After sterilization, all that remains is for the contact lenses to be tinted in the desired color (if necessary), packaged and labeled. Ready-made packages of contact lenses are stored in sealed containers at a constant temperature. But that's not all, certain part from a percentage of all finished lenses is sent to the laboratory for more detailed quality control, and if everything is fine, then the entire batch is sold.

Rotomoulded contact lenses have an aspherical back surface (not spherical, but its shape depends mainly on the centrifugal force acting on it during the hardening process in the mold). Centrifugal molding is the cheapest production method. You can get soft contact lenses with a thin outer edge and good performance.

Turning

The method is suitable for the production of both soft and hard lenses(for example with high optical characteristics).

Solidification of the monomer occurs in forms that are not subject to rotation. After solidification, the workpieces are transferred to a computer-controlled lathe, where, using specially developed software, lenses with complex geometric shapes (for example, with several radii of curvature) can be obtained. This requires maintaining constant environmental conditions (temperature +22 degrees, relative humidity 45%).

After turning, to give the surfaces the necessary smoothness, the lenses are sent for polishing. The lenses are then hydrated, chemically cleaned, quality controlled if required to be tinted, and sterilized.

But this method is about 4-5 times more expensive than centrifugal molding.

Casting

Casting (also called “in-mold polymerization”) is a less expensive method than turning. First, a metal matrix mold is cast (unique for each set of lenses), polymer copy molds are cast over it, into which the monomer is later poured. It hardens with the help of ultraviolet rays. The resulting solid polymer is sent for polishing and, depending on the required hardness, it is hydrated. And then, similar to other production methods - tinting, quality control, sterilization, packaging and labeling.

With the invention of silicone hydrogel contact lenses, after casting into a mold, they began to use plasma polishing (the lens is placed in a special liquid through which a certain type of electric current is passed) polishing. This allows for increased future wettability of the lens.

Currently, soft contact lenses for routine replacement and approximately half of disposable (one-day) lenses are produced by casting.

Pressing

Occasionally, a production method that is no longer particularly popular, such as pressing, is used. This method is reminiscent of casting, only it is not the liquid monomer that is poured into the mold, but the already hardened polymer “blank” is pressed using specially prepared molds (dry pressing), or the “blank” that has undergone hydration is immediately pressed

Mixed methods

The most common of the mixed methods is the so-called.” Reversible process III.” In it, the front surface of the lens is made by centrifugal molding, and the back surface is made by turning.

All this contributes to the fact that the front surface is extremely smooth (and this is comfortable to wear), and the back surface (adjacent directly to the cornea) has any fairly complex geometric shape.

As a result, contact lenses of the most complex shapes are produced using this method. Also a plus is the good oxygen permeability of the lenses. The disadvantages include a longer manufacturing process (in time) and a higher production cost.

Promising types of contact lenses

Nowadays, it has almost reached the production of prototypes. new type lenses called “Bionic contact lenses”. Of course, this will be the next step in the evolution of contact lenses, because ultra-small electronic circuits will be included in the lens. But how about modern lenses, bionic lenses will be of both a medical nature (vision correction) and an entertainment-professional nature (an electronic display in the eye). In the case of a medical application, it will even be possible to “correct” lens defects with electronics (say, due to inaccurate recording of the topography of the patient’s eye).

But the production of bionic lenses will also require a fundamentally new approach to their production. If production methods have already been worked out with the lenses themselves, then with the electronic filling it is more difficult. At the first stage, electronic circuits are made, assembled from metal plates several nanometers thick (1 millimeter is 1 million nanometers). On the other hand, the LEDs are planned to be only one-third of a millimeter thick, and applying them with tweezers will obviously not be easy, so they are sprayed as “powder” onto the surface of the lens. To accommodate such miniature components, a method called microfabrication or self-organizing assembly is used.

Finally

Unfortunately, the final result is still far away. Now the stage of searching for materials that will not irritate the user’s eye has been completed, and the fact of the direct presence of the emitting LED on the surface of the eye is also being studied. It is also too early to talk about the cost of such a “new product,” but it is clear that the first prototypes will be very expensive.

Production and sale of contact lenses – profitable business. It is not surprising that competition in this market is very high, especially among Western companies. In other countries, as in Russia, the main positions in the contact correction market are occupied by four main companies.

Slightly less than half of the market belongs to Johnson & Johnson. The shares of CIBA Vision Cooper Vision products account for 18% of the total volume. Bausch&Lomb takes fourth place with 12%. All other companies, including domestic manufacturers, account for the remaining 4%. Among the most popular contact lens care products, experts name: Opti - Free RepleniSH (about 23%), Renu MultiPlus (22%) and Free Express (17%). The remaining 38% are products from other brands.

As a result of the study foreign markets contact vision correction products, conducted by the independent research and consulting company Eurolens Research, the following portrait of the average lens user emerges. The average age of the consumer is 30 years. Moreover, in countries with a developed market for the consumption of contact correction products, the average age is higher (in Australia - 34.7, in the UK - 35.1, in Canada - 32.4).

In countries where this market is in its infancy and development, this figure is somewhat lower. Thus, in Russia the average age of an active contact lens user is 26.4 years. This is explained by the fact that young people, as a rule, care more about convenience and their appearance, they tend to experiment and try everything new, unlike older people who are more conservative.

In addition, according to statistics, women are much more likely than men to wear contact lenses. And if in other countries percentage is 67% and 37%, respectively, then in Russia more than 83% of the fair sex refuse glasses in favor of lenses. As a result, in our country the demand for colored contact lenses is especially high (about 14% of the total volume of soft contact lenses sold). Until recently, hydrogel contact lenses occupied the first place in sales. However, every year the popularity of daily contact lenses is increasing, which, however, still lags behind in sales volumes.

In developed countries, the situation is exactly the opposite: most Europeans prefer to use more harmless and comfortable contact lenses for daily wear, and lenses with a replacement period of 3-6 months have not been sold abroad for a long time. Unfortunately, Russian consumers prefer to save on their health by choosing lenses that can be changed less often.

Also, soft toric lenses are not in great demand in the domestic market. Experts are confident that the future belongs to silicone hydrogel contact lenses, which have a high moisture content and allow more oxygen to pass through to the cornea than common hydrogel lenses.

The production of contact lenses is a high-tech process that requires special equipment, qualified workers, and strict quality control. But there is no need for large areas: the production itself and the finished product warehouse can be located in the same room. There are several ways to make the most common soft contact lenses: centrifugal forming, turning, casting and a combined method.

When producing contact lenses using the centrifugal molding method, special molds are used in which the starting material, a liquid polymer, is placed. Under the influence of ultraviolet radiation and high temperature, the polymer hardens. During this process, the mold is constantly rotating: its speed of movement, ambient temperature, and the amount of polymer directly affect the final product. After the polymer has hardened, the lens is removed from the mold and undergoes a hydration process.

This type of production is less expensive than others, and at the same time allows the production of high-quality lenses with good stability and reproducibility of specified parameters. However, this method is not suitable for the production of lenses with a toric surface.

The production of contact lenses using the turning method is more complex and labor-intensive, therefore the cost of a product produced in this way will be higher. As a rule, lenses are produced by turning using individual orders or in small batches. The lens is literally machined from dense blanks of polymerized material.

Production consists of several stages. First, the workpiece is processed on a lathe, during which a lens with a thickness of 0.1 mm is obtained. Then it is polished, hydrated (placed in a special solution, after removal from which it becomes soft), chemical disinfection and tinted. Once the lens passes quality control, it is sterilized, packaged and labeled. Because each lens is turned almost by hand (albeit under computer control), it is thicker than lenses made by other methods and, as a result, has less oxygen permeability. Most traditional lenses are produced this way. Russian companies.

Large Western companies that produce lenses for routine replacement and daily wear in large volumes use a casting method that can significantly reduce costs during large-scale production. In this case, a base is first created in the form of a metal matrix with predetermined parameters. It is needed for making plastic replica molds.

Then the liquid polymer is poured into the lower part of the mold and closed with its upper component. The mold is irradiated with ultraviolet light, under the influence of which the polymer hardens. After which the used form is deleted. The remaining steps are similar to those used in other production methods: hydration, disinfection using chemicals, toning, quality control, sterilization, packaging and labeling. The resulting lenses are very thin - their thickness is about 0.03 - 0.05 mm.

The last, combined method, as the name implies, includes all methods of making lenses: first, using centrifugal formation, a lens with a smooth surface is produced, which then undergoes additional processing by turning.

The main domestic manufacturers of contact vision correction products are Optikon (Moscow), Optimedservice (Ufa), Concor (Vologda), Octopus (Samara). They work on modern computerized production lines and use imported material, produce lenses and produce lens care products (although more often solutions for lens care are made to order abroad under their own brand).

Their main advantages: low cost of production, strict quality control, wide choose large diopter lenses (from -26 to +26). Lenses of such refractions are not available in the range of Western companies. However, domestic products cannot yet withstand competition with foreign brands. Most of it consists of ordinary lenses, while all over the world they have long been replaced by daily lenses and routine replacement lenses.

The profitability of enterprises that produce lenses using the turning method is 10-12%. The profitability of production using injection molding technology reaches 100%. However, the costs of equipment in the latter case are many times higher, and they can only be recouped through large sales volumes. Meanwhile, sales volumes of the largest Russian manufacturers, which have their own representative offices in various Russian regions, produce no more than 300 thousand lenses per year. To promote sales, lens manufacturers actively cooperate with specialists in contact vision correction, offering them training, bonus programs, preferential conditions, etc.

Experts recommend that Russian companies doing business in the production of contact lenses pay attention to the niche special lenses– toric and bifocal, which are more expensive than usual. The demand for them, although not high, is still there, but there are practically no offers.

They are not in the most favorable conditions, and they are also deprived of government support, but companies are doing everything in their power to win the fight for their place in the market. In this article we will review the state of affairs in this segment of the domestic manufacturing sector.

If you look at the developed markets for contact vision correction, say, EU countries, then, as follows from regularly published reports from various agencies (for example, Eurom Contact), it is quite obvious that these markets are mainly filled with routine replacement contact lenses produced by large companies . These products have, to a certain extent, displaced traditionally worn contact lenses from the market. According to leading managers of large manufacturing companies, traditional contact lenses occupy a new niche for them: increasingly, these are contact lenses for those people who have limited funds, as well as special contact lenses made according to an individual prescription. Although, according to some production workers, the latter are, one might say, the bread of contact vision correction laboratories working in various regions of the country.

Apparently, a similar fate awaits traditional soft contact lenses in our country, although they currently occupy a fairly large market share (according to various estimates, up to 45% of the market). Just don’t think that this conclusion was made hastily - in principle, the Russian production workers themselves, with whom we were able to talk on this topic, agree with it, and it is to them that we will give the floor in the published material. But first, let's list those companies that produce contact lenses. This enterprise "" (Vologda) is the largest in terms of production volume, the companies "Opticon" (Moscow), "" (Ufa), "Octopus" (Samara), "Nevskaya Optics" (St. Petersburg), "Contlens", ( Arkhangelsk), "Likont" (Volgograd), PE Kunina (Belgorod) and some others. They all produce traditional wear soft contact lenses using the turning process.

To find out what problems our manufacturers face and what prospects they see for the development of their enterprises, we talked with representatives of a number of the above-mentioned companies and asked them to answer a number of questions. The director of the Concor company Viktor PROSYANYUK, the director of the Optikon company Boris DYMAN, the representative of the Optimedservice company Ural YANTURIN and one of the managers of the production and implementation company Octopus Sergei GOLOSCHAPOV shared their thoughts on this topical topic with us.

Veko: What share of the contact lens market, according to your estimates, is occupied by domestically produced products?

Victor Prosyanyuk: According to our research, about 50 percent, half of which are made by contact lenses produced by Concor.

Boris Dyman: Currently, it is difficult to estimate the market share occupied by domestic traditional contact lenses, but based on the total production volumes - which is approximately 30-40 thousand pieces per month - we can assume that this share is 10-15 percent, no more.

Veko: How do you see the prospects for the development of domestic production of contact lenses?

Victor Prosyanyuk: The sad thing is that things are not going very well for Russian manufacturers at the moment, some enterprises are even closing. It turns out that there is no unified development program, no support government programs, and our production is forced to follow the lead of large Western companies. One of the main problems is the pricing policy dictated by our market. If, say, in the West, traditional contact lenses are sold for 8-10 dollars apiece, then we are forced to set the price for scheduled replacement contact lenses - 2-3 dollars, as a result of which we work at extremely low profitability, almost to the limit. As a result, we cannot afford a broad advertising campaign and the purchase of more modern production equipment necessary for the manufacture of modern products - scheduled replacement contact lenses, contact lenses in blisters, solutions for the care of contact lenses.

Boris Dyman: The future lies in planned replacement contact lenses, the production of which is almost impossible for our entrepreneurs. Therefore, traditional contact lenses will be forced to occupy a niche product for citizens with a low level of material income, as well as for those people who are conservative in their views and are accustomed to these contact lenses, although the funds allow them to buy more expensive contact lenses for routine replacement. And this will definitely happen - a year earlier or a year later.

Sergey Goloshchapov: I don’t see any positive trends in the domestic production of contact lenses. I just look at things realistically, since I myself am a co-owner of a chain of optical stores and I see the dynamics of growth in sales of scheduled replacement contact lenses from 10-15 percent in 1997 to 87 percent in 2003. Sooner or later, traditional contact lenses will be forced out of the market, and our manufacturers will have, like in the West, to switch to the production of special contact lenses - for keratoconus, toric (astigmatic contact lenses), with high refraction; the rest will be taken up by scheduled replacement contact lenses. And it is not possible to start the production of planned contact lenses in Russia from scratch, unless Western companies themselves build here production capacity and will finally bring down prices.

Veko: How would you assess the state of the contact vision correction market, does it contribute to the development of our enterprises?

Victor Prosyanyuk: The market has great potential - so far the share of the population using contact lenses is 1.5 percent. If you look at European countries, the share there is 5-7 percent. It is to be expected that our market should achieve a similar share of contact lens penetration. Therefore, the market has great potential. In the contact correction market itself, alarming trends are observed - the number of primary patients is decreasing. This suggests that contact doctors should think more about their civic responsibility: their task is not to sell contact lenses, but to provide a person with full vision so that he is satisfied with the service. Then he will continue to use contact lenses. In the meantime, it turns out that the number of misconceptions about contact lenses as a correction method, which is fraught with terrible complications, is growing in society.

Sergey Goloshchapov: In 2003, our sales increased by 20 percent, and, in principle, since the founding of the company, annual growth has been 15-20 percent. Sales are currently carried out in all regions of the Russian Federation and other CIS countries. The most popular contact lenses are “Elite-38” with 38 percent moisture content.

Internal competition has established in the market between domestic producers, so that the price has frozen around 2-2.5 dollars per unit of product. Profitability is declining and currently it is very low - although the prices for the cost of materials do not change, the costs of rent, electricity, wages and so on, and therefore the cost increases.

Ural Yanturin: Over the past year, sales of contact lenses grew by 20 percent. This is due to the fact that we pursued an active marketing policy: we participated in all regional and central exhibitions and gave a lot of advertising. Are there any difficulties? Yes, in principle, no - there is good demand for our product. You just need to work more - and things will go well. The profitability of production is, of course, low. But you can stay afloat, you just need to work.

Eyelid: Many experts believe that lenses with 38 percent moisture content are unsafe for patients' eye health. Is it then worth producing such lenses at all?

Victor Prosyanyuk: Of course, we understand that contact lenses with a moisture content of 38% cannot be recommended to be worn all day. That is why we urge doctors to remember their civic responsibility and sell vision, not contact lenses. It is necessary to explain to patients the peculiarities of wearing contact lenses with low moisture content. Again, recognizing the disadvantages of contact lenses with 38% moisture content, we produce contact lenses with 70% moisture content. And now 55 percent contact lenses should be officially registered. We are also going to produce contact lenses with a 67 percent moisture content from materials from the Kontamak company - Contaflex 67.
Personally, I myself have nothing against scheduled replacement contact lenses: they need to be available in an assortment. But based on the situation in our country, offices also need to have traditional contact lenses. Not all residents of the country can now afford to change contact lenses every month; for them it is expensive. They need traditional contact lenses that last longer before being replaced with new ones.

Eyelid: Are there any difficulties with lens materials?

Victor Prosyanyuk: Of course I have. For example, “seventy” (with 70 percent moisture content) from “Lamda Polytech” does not suit us very much - its material characteristics fluctuate from batch to batch, so each time we need to reconfigure the calculation tables before production, having first run several dozen blanks. Also, when contact lenses are hydrated, the vinyl-propylene bonds of the polymer are poorly washed out, as a result of which some patients complain of a burning sensation in the eyes.

Veko: How can your company compete with the expansion of large Western manufacturing companies?

Victor Prosyanyuk: We can match big companies with our strengths. Firstly, our contact lenses have a wide range of parameters - from -20 to +20 diopters. As a result, contact vision correction offices often purchase, say, from Bausch & Lomb lenses with a refraction of up to -6 diopters, and the rest from us. And then, having tried them, they buy all the refractions from us. Secondly, with turning and three-stage quality control, we give defects at only 1.5 percent. The contact lens is checked for chips, microcracks, etc. after dry turning, then after hydration, and again before packaging. And another thing is contact lenses produced by stamping in large factories, such as, say, the same company Bausch & Lomb - as far as I know, they check the quality of only 10 percent of the product batch.

Therefore, and I am convinced of this, according to our GOSTs, exported contact lenses for planned replacement should be considered defective in 90 percent of cases. Our traditional contact lenses are much better quality. Please understand me correctly: I am not against any specific Western companies, but against the ideology of the dominance of planned replacement contact lenses. These contact lenses are manufactured with lower quality requirements, and accordingly, their recommended wearing period is sharply reduced. Traditional contact lenses can be worn more often, as their quality is higher.
Thirdly, we have the widest dealer network - there are no regions where we do not have an official representative office. Therefore, our contact lenses are more affordable and therefore the demand for them exceeds the supply.

Sergey Goloshchapov: As for the ability to compete with Bausch & Lomb, it makes no sense. Our contact lenses are designed for low-income people who cannot spend more. If they have other money, they will definitely switch to scheduled replacement contact lenses - health is more expensive. Again, our production base is becoming outdated. Ten years ago we bought new Gfeller machines. Now they are already morally obsolete, and they are also physically worn out. Maybe they'll last another five years. What then? Then there will be contact lenses everywhere from Bausch & Lomb, Johnson & Johnson and other major Western manufacturers.

Ural Yanturin: Our contact lenses hold their shape well and are easy to handle when putting them on and taking them off - this is what appeals to some patients. But the future, naturally, lies in planned replacement contact lenses, so we understand that sooner or later the production of traditional contact lenses will be forced to switch to the production of special contact lenses, as happened in the West.

Veko: How to survive with such bleak prospects?
Sergey Goloshchapov: That is why we have to deal not only with contact lenses, but also with other areas of the optical business - for example, glasses, laser correction.

. . .
So, as follows from the statements of most of our interlocutors, the prospects for the domestic production of contact lenses for traditional wear are not very bright. The market is increasingly filled with inexpensive contact lenses for routine replacement produced by large Western companies, and public awareness is growing that contact lenses for routine replacement are safer for eye health than contact lenses that are traditionally worn and have low moisture content. Accordingly, sales of foreign-made contact lenses are growing. However, at the same time, sales of Russian companies are also growing. Thus, most of our interlocutors noted an increase in sales of contact lenses of their own production over the past year - by an average of 10-15%. In principle, this is explained by the fact that the country is currently experiencing growth in the market for contact vision correction, and it is being filled with products from both Western and Russian companies. This allows our manufacturers to stay afloat, and in the case of, for example, Concor, even expand production and produce new brands of contact lenses, since demand exceeds supply.

As for the future, it is, as follows from the words of our interlocutors, still quite vague. As can be seen from the answers to the questions, the forecasts are disappointing: either a reduction in production, or a complete re-profiling, or even withdrawal from the contact vision correction market. Only Concor, as the largest production facility, is most optimistic in this regard.

Russian manufacturers of contact lenses

Octopus

The production and implementation company "Octopus" is one of the largest enterprises in the Volga region producing high-quality soft and hard contact lenses. Contact lenses are made from material from Contamac (Great Britain) by turning on machines from Gfeller (Switzerland) using computer controls. Here, the quality control of each manufactured contact lens is carried out.
The company was founded in 1993; so she turns 11 this year. In 1994, the company acquired production equipment from Gfeller (Switzerland), and a little later, with the help of specialists from Lamda Polytech Ltd. production was modernized. The range of manufactured contact lenses has also expanded: now Octopus produces soft contact lenses with 38 and 55% moisture content “Elite 38” and “Elite 55” from imported materials from Contamac, as well as hard and rigid gas permeable contact lenses. In addition to colorless contact lenses, Octopus produces cosmetic contact lenses using equipment from Lamda Polytech Limited.

Optimedservice

The Scientific and Medical Association (NMA) “Optimedservice” was created in 1993 and today occupies a leading position in the ophthalmological market of the Ural region. Since 1994, the company has been producing soft contact lenses under the “ ” brand on a computerized production line from City Crown (UK). One type of lenses is available: “Optimed-38” with 38% moisture content.
See more details here...

The Concor company appeared in 1991. Initially, the production of contact lenses was carried out using domestic equipment. However, it did not provide the quality of contact lenses sufficient to create competitive products, and in 1993 it was decided to purchase from Lamda Polytech Ltd. restored machines from Chase. This was a qualitative step forward, and products from Concor began to gain popularity among contact doctors.
Today the company produces soft contact lenses under the Concor brand - from the materials Hypolan-2, Benz-38 tint, LM-70VP. The registration process is for traditional soft contact lenses with 55% moisture content.
According to research conducted by the company, Concor products currently occupy 25% of the Russian market, another 25% is the share of other domestic manufacturers, and 50% are Western-made products, half of which are from Bausch & Lomb.

Optikon

The Optikon company was founded in 1991 by employees of the NPO Medoborudovanie, who had great experience in the production of the first domestic soft contact lenses from the Hypolan material (as well as in the development and creation of this material itself). In addition to Gipolan, the company tried to produce contact lenses from materials from Lamda Polytech Ltd. and “Vista”, but in the end she chose the materials “Benz” and “LM”.
The Optikon company produces soft contact lenses under the Optikon 38 and Optikon 72 trademarks. The former are made from “Benz 38” material, the latter from “LM-70”; Colored versions of these lenses are also available.

Vadim Davydov, Veko No. 5 (79), 2004

Contact lenses are a medical product that allows for the correction of various abnormalities resulting from eye diseases. Most often, you can find products on sale that are made with people in mind who suffer from myopia (myopia), that is, those who have difficulty seeing at a distance. For patients with farsightedness (hyperopia) there are also models, it’s just that there are much fewer people with such a vision defect. Yes, and myopic people actually have to large quantity spend time wearing glasses/lenses so as not to experience discomfort in Everyday life. There are also options for correcting astigmatism.

You can select lenses for yourself only after visiting a specialist who will conduct a full examination and write out a prescription. Even if you have been a user for many years, before changing one brand to another, do not be lazy to visit an ophthalmologist. Contact lenses from different manufacturers and different lines differ in “design” from each other. This concept usually includes parameters of the shape of the front and back surfaces, diameter, thickness at the center, base radius, and so on.
