How to choose sunglasses
Material shall be a primary criterion in choosing sunglasses, because health is more important to the style or image. Glasses not only help protect your eyes from bright sunlight, but also do not allow UV light (only glasses with glass lenses). Just wanted to say that too small glasses (whether glass or plastic) though will look stylish, but will be a poor tool in sun protection.

Sport, recreation and sunglasses
For sports sunglasses special requirements. They not only must reliably protect your eyes from the sun, but have increased strength, to be made of special plastic, not glass, because glass increases the risk of eye injuries. According to statistics, 90% of eye injuries could be prevented if protective eyewear, with nearly half of all injuries occurring in children under 14 years.

How to choose glasses for a child?
In the first year of life, the main indications for correction are aphakia and high myopia. In children under the age of three leading indications for correction of hyperopia is for esotropia. Preschool children (3-7 years) to correct aphakia, congenital myopia and hyperopia are added early acquired myopia and astigmatism. At school age, the leading indication for the correction of myopia is acquired.

How to pick the right rims of the glasses?
New Year - the right moment to change the old, familiar, or start something new. For example, you can radically revise its image, or even just thinking about it. Think we'll start with the principal, and most importantly to us, loved ones, of course, the eyes, and everything associated with them.

Participation points is a fairly serious procedure. Many people, especially women, are choosing to purchase the frames as a costume or decorations. The frame should be modern, "trendy" and yet have to face, color and styling your hair, and jewelry.

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.

Polarizing eyeglasses. What do they differ from ordinary sunglasses?
Although the cost of those and other quite comparable, but the fishing is desirable polarized glasses. How to check whether the data points polarizing? Very simple. Take two pair, and lean their glasses to each other. You will be able to see through them. I now turn to some points by 90 degrees. 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?

Sunglasses - Accessory enigma
The bright sun is often the cause of the appearance of wrinkles. On clear summer days, it is impossible to watch without squinting his eyes, especially if it is near sea. Sunlight reflected by water, shine in mercy. The only salvation in the hot, cloudless days are the sunglasses.

Reliable protection of eyes

Sunshine and some types of artificial lighting can be not only enjoyable, but also dangerous, especially for eye tissue, is very sensitive to the effects of ultraviolet radiation. What tools can reliably protect the eyes from harmful ultraviolet radiation? Can cope with this problem day contact lenses? We offer you now understand these issues.
Dangerous UV

Eye protection from harmful ultraviolet (UV) radiation, the main source of which is the sun takes on in these days of increasing importance. As environmental degradation in many countries around the world suffering primarily the Earth's atmosphere, depleting its defensive resources, including the ozone layer and thus increases the effects of solar radiation on the skin and eyeglasses

Specialists have long been sounding the alarm, regularly reminding the general public about the need to protect the eyes from harmful ultraviolet radiation. So, back in 1998, one of the articles in the magazine for contact correction of Contact Lens Spectrum begins with a question: "Is there anyone among the most important issues that you discussed with the patient, the question of robust protection of the eyes from ultraviolet radiation?" Just below was given the fact : "On a sunny day stay for 30 minutes on the streets of New York may lead to the development fotokeratita, who often carried a very painful, because it causes damage to the corneal epithelium, where a high concentration of nerve endings. Such a short stay on the street may also cause less serious consequences, such as the feeling of sand in the eyes ".*
UV-B radiation on the street and indoors

Winter time - is not cause for complacency regarding the harmful effects of ultraviolet radiation. Moreover, in this season of his influence can be even more intense than in midsummer. The reason is that the snow cover has the ability to reflect up to 80% of ultraviolet rays. Such super-high doses of ultraviolet detrimental effect on the cells of the eye and can cause visual impairment up to blindness.

Not surprisingly, because of the very bright light reflecting off the snow surface, some skiers and mountain climbers there is an extreme form of fotokeratita - snow blindness. Then to restore vision takes a few days, in some cases, this phenomenon may lead to complications such as chronic eye irritation and lacrimation.

But not necessarily a long time to be outdoors, to get a dangerous dose of ultraviolet light, some people are close to the sources of such effects directly in the workplace! As was confirmed in several studies, although in general indoor UV radiation does not exceed a threatening level, this rule there are exceptions. For example, the dangerous effects of ultraviolet radiation may be employees of television studios, visitors to exhibitions and other events, such as fashion shows, when used very bright mercury vapor lamps that emit significant UV dose .**
Convenient and reliable protection

Having said earlier it should be stressed that another important role in protecting the eyes from the harmful effects of ultraviolet radiation is given contact lenses with UV-filter. If being on the street, a man wears sunglasses and extra contact lenses, the latter also contribute to the full protection of eyes from the harmful effects even if not directly, but reflected from the earth and clouds of ultra-violet rays can easily penetrate under the goggles and reach the cornea and internal areas of the eye. When he enters the room and remove the goggles, the lenses will remain on the eyes and will continue to perform its protective function.

With the advent of winter, contact lenses have become especially important because, unlike glasses, they are conveniently combined with sports gear for seasonal sports and recreation, the latter include, for example, ski masks, hockey shields for eye masks for riding on snowmobiling, etc.

Among the contact lens would particularly like to highlight the daily replacement lenses: they do not require absolutely no care, and because during the fleeting winter vacation can be a very convenient means of vision correction. However, the question arises: whether the one-day contact lenses ineffective to protect the eyes from ultraviolet radiation? Because they were originally intended for such a short wearing? Not at all. One-day lenses can be rightly called not only convenient, but reliable in all respects. Let's make sure this with specific examples.
