It would seem, to acquire contact lenses easier than simple, these are not glasses with whom we have to suffer with hours, picking up a frame. However, when it comes to a visit to optics, we are lost... Eyes run away from a variety, and the consultant confuses the smart terms, the names of firms and materials.
What is now worn
Now on the Russian market of manufacturers of contact lenses more than enough. The most famous: johnson&Johnson, Vision Care, Ciba Vision, Bausch&Lomb, Maxima. Almost all of them offer a complete line – from one-day to lenses prolonged wearing mode.
By the way, it is one-day (disposable) lenses and those that can be worn without removing, are the priority directions of scientific research of leading manufacturers. «Daily» attract consumers with their convenience – «put on, removed, threw», «Long-play» – what «put on and forgot».
One-day lenses
The main minus «Daily» – Lack of moisture and low oxygen permeability of material. Therefore, manufacturers without tired inventing humidifiers, «Built-in» In the lens and released during the day, or, on the contrary, add components to help keep the existing moisture. Such lenses are made from biocompatible materials, which makes it possible to ensure their comfort and safety.
However, recently the Russian market is not spoiled by new «Daily» – The most progressive remains released several years ago «Focus Dailies All Day Comfort», «1-Day Acuvue Moist» and «Maxima 1-day».
«Daily» – The most expensive from the lenses presented in the market. That is why doctors often do not even offer patients to try them. And in vain. In the end, each of us is able to independently plan your budget without the help of doctors. «Daily» Perfect people who suffer from allergies, those who usually wear glasses, and lenses use only sometimes, as well as children, travelers and lazy. Such lenses according to doctors – The safest.
Lenses of prolonged wearing mode
Previously, lenses were made from the material called Hydrogel – They had to be removed on the night and put in a disinfecting solution, and in the morning to wear again. All sleep attempts in such lenses ended in deplorable – Patients were blossomed and elevated eyes, increased risk of eye disease. All this was the consequence of low oxygen permeability of the hydrogel. She, of course, is higher than that «Daily» (in which it is categorically impossible to sleep), but still not enough for the comfort of the eye for a long time.
Modern long-playing lenses make from more perfect material – Silicone hydrogel. Such lenses have the highest indicators of oxygen permeability, which makes it possible to ensure increased comfort in continuous wearing – eye in such a lens «breathe».
Last achievement of developers of silicone hydrogel contact lenses – «Acuvue Oasys WITH HYDRACLEAR PLUS». The so-called moisturizing agent has been added to their composition. It prevents eye drying and, accordingly, increases the comfort of lenses.
«Moisturizing and breathable» Lenses can be worn without removing, seven days, after which they go to the garbage. None of the previously released silicone hydrogel lenses of moisturizing agents do not contain, so that the appearance of new items will most likely force the rest of the manufacturers, too, invent something like that.
When there is no agreement in comrades
Unfortunately, despite all the novelties and inventions, the complete unanimity between the manufacturers of contact lenses and ophthalmologists is not yet.
Judge for yourself. Information-advertising from some manufacturers: Silicone hydrogel lenses can be worn without removing, within 30 days. Yes, certifying organizations give permission to such a long wearing, but doctors categorically against! The latest models – Already mentioned «Acuvue Oasys WITH HYDRACLEAR PLUS» and comparable to them «O2Optix», appearing a little earlier, intended for continuous wearing only for 6-7 days. Feel the difference?
Doctors warn that continuous wearing lenses longer than 7 days is fraught with serious complications (right up to the corneal ulcers). If you are too lazy to monitor the deadlines, messing with solutions and containers, do not bring yourself to the state of Gogolevsky Viya (when you can't even be able to raise the eyelids in some unprofiled in the morning) – Buy «Daily».
Selection of professionals
From the appearance of contact lenses won everything. And cloaks, from childhood struck by unkilled classmates, and people with very poor eyesight, whose glasses often look ugly because of the thickness of the glasses, and those who are staring at the monitor screen as m
s with you.
It is believed to sit at the computer in the contact lenses much more convenient than in glasses. They do not glare, and the field view is more. On the other hand, users of computers wearing contact lenses often complain of dry eye. This is due to the fact that a person looking at the monitor screen, blinks about 3-4 times less often than usual. In addition, eyes dried office air conditioning and dust micro-mask. Plus the evaporation of moisture from the lens surface is higher than from the surface of the eye. Here I am «Syndrome dry eyes» With the feeling of sand, sailters, burning in the eyes. Therefore, experts recommend to work at a computer to wear lenses, which are well held by moisture, that is, the newest developments.
Almost most of all from the appearance of comfortable contact lenses won athletes (and people leading an active lifestyle). Imagine a football player or biathlete in glasses... Funny! But the contact lenses them are very easy to face. Even swimmers can wear contact lenses. Moreover, lenses protect eyes from chlorinated pools water. The only thing that risks waterfowl laminaters – Sit down without lenses. In the water, the lens can simply «Space» From the eye, and find her in a bluish abyss is unlikely to succeed.
Contact lenses protecting eyes from ultraviolet radiation today is not uncommon. But so far, even manufacturers can not decide: does it make sense to do a UV filter lenses or not. So, for example, the company «Bausch&Lomb» still not introduced UV absorber in any type of contact lenses. The company believes that the lenses with UV absorbers do not provide one hundred percent protection of the eye from ultraviolet.
Lenses against astigmatism
Most recently, a unique novelty appeared on the Russian market - soft contact toric lenses intended for the correction of astigmatism. This is a practically revolution in the world of contact lenses, since earlier the possibility of contact correction of astigmatism could only dream.
Today, many optical salons hang posters on which a symbolic sun is drawn from a drop, and at the bottom of the signature: Look in turns right and left eye. If any rays «Sun» Change the color - you urgently need to see the doctor for the diagnosis and novelty.
Justice for the sake of say that with my girlfriend recently burned to such a poster. As a result, both for the novelty were to go - and she, with long-diagnosed astigmatism, and I just had an oculist confirmed his full absence. So trust doctors, not advertising posters!
