10. Choose the right color
Sunglasses lenses can be green, brown or gray. Extravagant blue, red, purple and orange distort the color perception and lead to increased eye fatigue.
9. Choose wide shackles
It is wide arms that provide lateral protection from sunlight. In properly selected glasses, the sun should not be seen in the eyes either from above or from the side.
8. Do not believe the dark lenses
Cheap glasses for a couple of hundred rubles can have coal black lenses and do not protect your eyes from ultraviolet. Moreover, extremely dark lenses can harm the eyes, if made of cheap plastic - in the conditions of blackout the pupil will not narrow, and thus harmful ultraviolet penetrates into the eye, which is not delayed by a cheap lens.
7. Glass and plastic are equally good
Each of the materials has advantages and disadvantages. Plastic lenses are light, do not fight, but are easily scratched and protected from ultraviolet radiation only if they are coated with special filters. The glass does not let the ultraviolet pass, but it easily fights and weighs a lot. Optimal option - choose high-quality plastic and UV-filters.
6. It is important to read the
label The design of the glasses is, of course, important. But more importantly, the information on the label. It's easy to decipher the data - the inscription "Blocks at least 75% UVB and 60% UVA" means that the lens blocks 75% of the type B UV rays and 60% of the type A. Ophthalmologists recommend choosing a protection of at least 50%.The label can indicate the filter category from 0 to 4( from minimum protection to maximum).
5. Do not buy without fitting
The frame should not interfere, the weight of the glasses should be acceptable, and the lenses should not distort the picture and color rendition. If the world around you loses clarity in glasses, you better refuse to buy.
4. Think of the need for a lens with polarization
Polarizing lenses make it impossible to see the sun's rays reflected by different surfaces( for example, snow and water).Such glasses will be useful on the sea coast, as well as for sports.
3. Look at the photochromic lenses
These lenses change their degree of dimming depending on the brightness of the sunlight. Very useful such lenses will be for those who constantly wear glasses with diopters - with photochromic glasses can not be left on the street and indoors.
2. Try the right
Putting on the glasses for the first time, you need to shake your head a little - the glasses should not fall off. At the same time, they should not squeeze the head and the bridge of the nose. The ideal option is to go out with glasses on the street and evaluate comfort. The douches of glasses should fit the length, the temples can be rounded or straight - in the first case they should easily fit the ear, in the second - do not interfere and do not slip.
1. Ask documents
As a rule, quality sunglasses are sold in optics and tourist shops. But in any case, each pair must have documents - a liner with a description of the characteristics of the lens.
