Improving appearance points lenses
Vysokoprelomlyayuschie 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. Variety vysokoprelomlyayuschih range of 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.

Contact lenses
It is believed that the eyes of the lens blush, "dried" lacrimal gland, eyes acquire a specific shine (not the greedy, not that ravenous), triggered by a myriad of diseases and so on. I wear lenses for more than 4 years. With regard to shine in the eyes and other cosmetic effects of the MCL, then I am with my close friends spent the experiment: one in the eye lens, the other without.

Spectral points or more on computer vision syndrome
American Association of optometric studies published data on the new occupational disease "Computer vision syndrome" - (KSZ). Computer vision syndrome in one form or another is observed in 100% of computer users. His symptoms are familiar to almost everyone who holds the monitor more than 4-5 hours a day. Ophthalmologists note the rapid growth of cases of SGC. For example, in North America with typical complaints of the SGC to the doctors turned to 1992, 10 million people. In 1996 - 15 million people., And in 1998 for 22 million people.

If you continue to see through the glass, then the conventional glasses, but if you do not see - that's all right - you are in the hands of polarized eyeglasses. What it does affect fishing?

Lenses and extended wear lenses

Deciding to buy contact lenses, each patient is given a logical question: for a maximum time of wearing them calculated? 

The same question was agitated and producers contact optics, so the relevant studies were conducted. Analyze had a lot of factors: the material elements, their parameters, mode of transportation, ways of cleaning and storage conditions, the composition of tear fluid patient carrier, even the surrounding environment. As a result, scientists were able to establish that the maximum period of wearing lenses not exceed 12 months. After this period, doctors strongly recommend to move to a new pair. However, there is another option: some optical shops offer their customers a special service - cleaning of contact lenses in the laboratory that saves patients from having to buy a new kit. 

Research opticians have led not only to determine the maximum permissible period of wearing lenses. Analyzing the data obtained, Doctors concluded that the maintenance of contact lenses, even within the acceptable year may cause complications hypoxic nature. This was especially true nizkogidroprofilnyh lenses, because they are badly missed oxygen to the mucosal eyeglasses. Therefore, the market were released vysokogidroprofilnye lenses that are better able to pass through the oxygen saturation moisture. But it became clear an important nuance: due to the increase in hydrophilic lenses shortening the duration of use, and optics have recommend to change them every six months, and some even once in three months. 

However, this did not stop producers - appeared lenses, designed for only one week of wearing. They called lenses planned replacement. They quickly became popular, as were a very important advantage - convenience and simplicity in operation: there is no need careful care, because after seven days, still needed a new pair. In addition, significantly decreased risk of allergic reactions and infections, because in such a short period at the lens surface were unable to be formed deposits. 

This is interesting:
To date, the planned replacement lenses are most popular. In many European countries and in Russia, including sales leaders are lenses designed for 1-3 months of wearing. Many salons optics even stopped to offer patients longer-term lens, and now they can be bought only by prior arrangement.
