Glaring sunlight, as well as looking at snow in the most glorious winter weather, puts a strain on the eyes. Sunglasses protect the wearer from too much light exposure to the sensitive eyes and allow him a protected view. Drivers in particular appreciate this.
What are sunglasses?
Sunglasses protect the eyes from too much light exposure and in many cases also look very cool. Especially in road traffic, sunglasses provide excellent services. Easily it comes to a carelessness by sudden incidence of light, which blinds the eyes for a short and dangerous moment. The driver spontaneously squints his eyes and risks an accident. If the sun even comes from the front and constantly dazzles, light protection is essential. The eyes are protected, the view is clear. Mountains of snow on winter vacation is the most beautiful thing a skier can imagine. But an unprotected view of the white splendor in bright sunshine can really hurt the eyes. But even those who go on vacation in sunny countries cannot do without sun protection for their eyes. In addition to light protection, sunglasses also provide protection against irritation of the eye. Especially the inhabitants of northern countries are not used to glaring sunlight from morning to night. Therefore, you should not do without sunglasses on your summer vacation.
Shapes, types and types
There are countless types and shapes of sunglasses. In addition to the inexpensive light protection from the supermarket, which you put next to fruit and vegetables in your shopping cart, many people are enthusiastic about a more expensive model from the optician with in-depth type and style advice or they buy, for example, a “Ray-Ban” brand glasses directly from the Internet. Everywhere a rich selection was waiting for the buyer. Whether with plastic frame or with a frame made of metal – there are no limits to the imagination. Gladly worn are models that are unique in shape, color and design and should give the wearer that certain “something”. Mirrored glasses look mysterious and dangerous, while glasses in orange or other colors are trendy. Children also do not come up short, although the price for children’s glasses is by no means cheaper, just because the sunglasses are kept a little smaller.
Structure, function and mode of action
Even those who suffer from impaired vision and rely on glasses for everyday life, do not have to do without sunglasses. Ground lenses in his visual strength attenuate the incidence of light and at the same time allow a sharp view. Drivers in particular, who need to see without error, almost always have sunglasses with lenses that compensate for their visual impairment in their glove compartment. Of great importance are not only the tinted lenses, but also the shape of the frame. This is because some frames allow sunlight to fall in sideways or over the lower and upper edges, which usually occurs at the wrong moment and can cause dangerous situations, especially in road traffic. Polarizing filters protect the eyes and improve visibility in difficult light conditions even better than conventional sunglasses do anyway. A special film on the lenses absorbs all unpleasant reflections so that they do not reach the eye in the first place. After all, glare in winter sports or as a traffic pilot can have fatal consequences. Sunglasses with plastic lenses are particularly easy to wear. After all, they are half as light as glasses made of real glass. Anyone who has to wear their sunglasses for a long period of time will definitely appreciate this convenience.
Medical and health benefits
A good pair of sunglasses not only gives the wearer a glare-free and better view, but also protects the sensitive eye from ultraviolet radiation. If the eye is exposed to this invisible light for an extended period of time, eye irritation and even disease, including blindness, can occur. Cyclists, whether professionals or hobby cyclists appreciate the eye protection not only its property as a light filter. Insects or dust particles that fly into the eye during a bike ride are also extremely annoying and painful and are intercepted. The dreaded snow blindness, although in most cases it disappears all by itself after a few days, is prevented by wearing protective goggles. Some people who suffer from severe eye disease must always and constantly wear sunglasses, so that at least the rest of the eyesight is preserved.
