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.

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.

How to choose sunglasses

Today buy them is not a problem, sunglasses can be bought in almost any store. Main how to choose those that are and will look beautiful, and to protect our eyes from the bright sun. First you need to be defined with the material and color lenses, it's the most important parameters in selecting eyeglasses. So what do you choose glass or plastic? Glass protects against UV light, less distorting items and reduces, in comparison with a plastic counterpart, the possibility of scratches. But the glass lenses are not safe: can shatter and under adverse conditions fragments often damage the eyes. They have high abrasion resistance, but much heavier than plastic lenses, mist and more fragile. Glass lenses are not suitable for children. 

Lenses made of plastic and glass is easier to secure. But plastic is not processed by special means, as well as the one "processed" handicraft, passes ultraviolet rays, and therefore hurts the eyes. But there is a lens with special chemical ingredients, which retards the harmful radiation, although in this case, the high quality of plastic should be guaranteed. These points should not buy in random stalls and markets. In the manufacture of plastic lenses are leading producing countries such as Canada, Germany and France. The structure of modern plastic lenses for glasses are special chemical additives. On the surface of glass and plastic are applied various sputtering. This is - anti-glare, antistatic, water-repellent, sunscreen and photochromic coating and darkening. These coatings on plastic lenses, single and multilayer guarantee absolutely harmless to the eye. The basic principle of selection of sunglasses with plastic lenses -- focus on those that do not allow the ultraviolet rays. They are of two types: A and B. However, the second, B-rays, ophthalmologists considered more dangerous. The labels of quality points there is the inscription: "Blocks at least 90% UVB and 60% UVA". 

Figures, of course, vary. This inscription is deciphered as: "lenses do not pass 90% of ultraviolet rays B and 60% UV A ". The labels branded glasses are specified wavelengths that do not allow the lens. full protection from radiation provide glasses showing 400 nm (nanometers). Their ultra-violet spectrum protection from waves of up to 400 nm. If same figure is below 400 nm, the glasses partially miss passing ultraviolet. There are indicator - refractive index: 1,4; 1,5, 1,6, etc. The greater the ratio, the better the lens, that is more subtle and transparent. 

Quality plastic lenses can be determined independently. Put the lens on a cloth with a square weave fabric. Better lens, the smaller the distortion of the structure of tissue, covered by a lens. The second "Ultraviolet" test requires time to wear -- area around the eyes, secured good points remain untanned. 

By the way, if the glasses are small and do not fully close their eyes, they do not protect from the sun.

Now choose the color lenses. Experts believe that the most suitable for the protection of the lens is dark gray and dark green shades. The first can actually perceive the surrounding colors, and the second largest number of ultra-filtered and infrared rays. And here is wearing rose-colored spectacles affect the psyche, to the same red spectrum can lead to loss of orientation, as vitiates all colors. If you wear glasses with blue lenses, you immediately become uncomfortable. And for good reason: they stimulate dilated pupils, which can lead to burn the eyes. Drivers are most suitable glasses with gray and brown lenses. And when poor visibility yellow. 

Heavily shaded, and have the mirror effect glasses are suitable for recreation in the mountains, on water, with a very bright light. Since the material and color lenses, we have decided now is the time to pick up a frame-to-face. 

Stylists approach to the problem of color matching spectacles very strict.

For example, blondes are advised to buy a frame of black, blue or green colors. You can afford a little more diversity. For example, buy glasses frame which resembles the skin of a leopard or a crocodile. Brunettes, by contrast, will look irresistible in something light: a silver-gray, for example, or golden. Redheads themselves quite stylish, sunglasses can be with lilac, green, blue rim. 

For those who prefer a noble gray hair, you can use any color frames, except for a gray (not silver) and yellow (but not gold). 

Square face becomes more correct form, if the optically reduce the width of the cheeks and lower jaw. To achieve such effect will help you greatly sitting on the nose points downward slightly rounded shape, a thin metal frame. Rectangular face is characterized by a certain elongation, which can be reduced by wearing massive glasses with broad jumper on bridge, mounted in black or dark brown. 

If you have a triangular face, choose a low sitting on the bridge of glasses in a thin metal-framed oval, with small lenses of pale colors. They are too broad forehead and narrow chin will look more balanced. By person most correct - oval fit almost any pair of sunglasses. 

And if you're chubby, pay attention to the points of a rectangular shape, without rounded parts with a frame is very dark. They your face will look narrower. So, make a conclusion: what is to pay attention, buying sunglasses. 

Optimal for the eye lenses of gray shades. They are able to filter the perceived light spectral range. Give up on the blue-violet range of lenses, at least in glasses for extended wear. Ophthalmologists around the world come to conclusion that the lens can not stand the blue color, so they should beware. This fashionable novelty, as purple ochechki can 
be as extravagant piece toilet, which is used rarely and briefly.

For the urban environment is more appropriate medium darkening lenses - about 50% for the mountains and the beach, select darker glasses -- than 60%. Useful for uniform darkening of the eye lens. Points at which the upper part is darker than the lower, and the more points with multiple zones of intensity dimming, tire the eyes. They can be worn only for a short time and people with good eyesight. 

When buying sunglasses, check carefully whether scratches, roughness and irregularities on the lens. Pay attention to the quality of the frame, a few times, open bow, slightly bend them, "prinoravlivaya" to their zaushinam. Good frame different elasticity, instantly taking on new shapes and easily recovers its original shape. 

Finally, check to see whether the crush on the bridge of the nasal stops, do not shake a bow. And finally: branded sunglasses have data on the manufacturer not only on the attached label. Brand reputable firms and collector's number is displayed on the inner side of the arc points and the corner of the lens itself.
