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.

What you need to remember when choosing a frame for glasses?
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.

Sports glasses 

In the lives of many sports played a very important role. Moreover, for many it is just the same meaning of life. What if man led astray by some kind of sport, visually impaired? What, for example, basketball or amateur scuba diving, downhill skiers or tennis player, if he can not see beyond their own noses? 

Even if the athlete is normal, it often may need sunglasses, and run after the ball, if they are constantly "Jump off" from the nose? Even fishermen need to protect themselves from ultraviolet radiation, because sunlight is reflected from the water and blinding. 

Output has long been invented global manufacturers of optics - they simply connect points for the correction with glasses against the sun, having in each model multi-functionality, convenience and quality. To date, the choice of sports glasses so large that You can easily pick up lenses for almost any sport. For example, for people involved in skiing, very important not only protection from ultraviolet radiation, but also maximum safety glasses, their impact, because this type Sports paired with frequent falls. 

Not every model points can be called a sport. Distinguish goggles for sports from conventional sunscreens may be on the following features: 

- They kept on the head by an elastic band, rubber band or dual-fixing in the form of arches and erasers;

- Part of the corrective lenses made of impact-resistant plastic and is protected by an additional layer to withstand the mechanical load 

- Virtually every sports car is equipped with a ventilation system;

- Frame is made so that the impact or fall to protect the eyes from damage.

The most popular in the last few years, enjoy sports glasses, adjacent to the face. The reasons for this unusually simple: a form of frames provides the widest field of view, so people do not have to turn my head or squint to cover eye space on either side of himself. Adjacent frames as if repeating horizontal facial contour of the eyes and temples, and it gives added protection against dust, wind, rain and bright light. And, of course, not forget about the fact that they look stylish and modern, which is also of great importance. 

The only drawback of sports eyeglasses with attached mounts is that they are rarely equipped with corrective lenses. The modern production of lenses with diopters mostly "works" with flat surfaces, that is, with lenses having small radius of curvature. Making curved lenses are too burdensome and costly. In addition, a lens with a large radius curvature cause problems for fastening in the frame - not yet found a reliable way of fixing, and security for sporting points is perhaps the most important parameter. And in terms of optical correction of curved lenses - not the best output: by the curvature they distort the image, which can lead to the development of astigmatism and prismatic effect. 

However, some manufacturers of optics still trying to create spectacles that combine sporty design and function of correction view. Special computer programs calculate the maximum allowable radius of curvature of corrective lenses, which their optical power did not undergo a change. However, such glasses have not yet gone on sale, and produced in laboratories individual orders, which naturally affects their value. Those who can not afford such a luxury, but want engage in sports and at the same time to see well, you can advise the best option - Suspended corrective clips, fastening on spectacles. The choice of these clips are extensive enough to be able to find a suitable pair for each concrete frame. That will have the same effect - vision correction, plus protection from sunlight. And a good economy, since one and the same frame can also serve for everyday use, and for leisure.
