How to choose sunglasses?

The acquisition of such an accessory, necessary on sunny days, like sunglasses, is a matter of good taste and awareness of the latest fashion trends. Quality glasses will not only be a good decoration, but also a reliable protection of the eyes from harmful ultraviolet radiation. So, how to choose sunglasses?

How to choose the right sunglasses?

The solution to this important task begins with the definition of the material from which the lenses of your glasses will be made. There are only two options: glass or plastic.

Plastic itself does not protect against UV radiation, so the effectiveness of such glasses depends entirely on the filters applied over it. Lenses from this material are easily scratched, so when you purchase these glasses, you should immediately buy a suitable cover. However, the advantage of plastic is that it is safe, such points do not crumble when broken down into small pieces, but simply become covered with a cobweb of cracks.

Glass, in contrast to plastic, does not let the ultraviolet pass at all, so you can buy such glasses even if they are almost transparent or very faintly obscured. Glass lenses are almost not scratched, but they can crash, which is very dangerous. Therefore, those who drive a car or engage in active sports, such glasses should not be worn. In addition, the glass is much heavier than plastic, which creates an additional burden on the bridge of the nose.

Now consider how to choose the right sunglasses, depending on the degree of their protection. There are 3 main types of sunglasses.

1. The first - cosmetic glasses, they are marked "Cosmetic". Such glasses pass from 51 to 100% of the radiation and are worn when the sun is not too bright, for example, in the evening or in cloudy weather.
2. The second level of protection - General - universal glasses for everyday wearing in the city. They block from 50 to 70% of ultraviolet rays.
3. The third level is the high UV-protection glasses. These glasses completely block harmful rays and they can be worn on vacation at sea or in the mountains.

Data on the degree of protection can be found on the label, as well as from a certificate that is necessarily available for quality sunglasses. Usually there is information about two indicators of protection from UV-rays: A and B-category. When answering the question of which sunglasses to choose, ophthalmologists recommend buying those models where both indicators are above 50%.

How to choose the shape of sunglasses?

But quality glasses can not only safely preserve the health of your eyes, but also be an excellent accessory that adorns and complements the image. The main rule when choosing sunglasses: do not buy them the same shape as your face. For example, chubby girls should not buy round sunglasses. A universal form, which is suitable for almost everybody, is teardrop, that is, fashionable aviator sunglasses.

When choosing the shape of the rim and the earrings, you also need to orient yourself on the facial features. So, girls with large features are suitable for this season's topical rims and wide arches, while girls with smaller features will decorate glasses in a thin metal case. Fashionable for the past few years, mirrored sunglasses with thin handles will be the perfect choice if you are in doubt as to which form will suit you most.

It is worth paying attention to the width of the glasses. They should not protrude strongly over the edges of the face, but they should not be too. Optimum ratio: the width of the frame is 1.5-2 cm larger than the width of the face in the place where the glasses are worn. Accounting for this condition will help balance and harmonize facial features.
