Picking up points for the driver, the first thing you should pay attention to the convenience. Indeed, if this characteristic is missing, in the best case, this will lead to discomfort and at worst to an accident.
Thus, before buying glasses you should try them and if they are socket: pressing on Veski, nasal bridge, or, for example, cause itching in the area of contact with the skin, you should choose another model, devoid of these shortcomings. Then, you should inspect the build quality points. If the lenses are loose in the frame and the whole design looks flimsy and unreliable, then the purchase of such points also should be avoided because they are likely to slip from its rightful place, constantly distracting the driver. Perfect rim with a narrow rim and sauchinone, which allows you to change lenses. In this case, you will no longer need to buy several models for different purposes – relaxation of the eyes, shading, etc. Great example of these products are sunglasses polaroid (http://trade-city.ua/catalog/glasses/p120/135/). You should also take note that the width of Saosin should not exceed 6mm, but they must be attached either to the bottom or the top, but not to the middle. Glasses with such design will provide a better view in the side mirrors and the rearview mirror.
Lenses. In practice, plastic is more practical than glass. They are easier, less mist and less traumatic. It is best to choose polycarbonate plastic lenses with special hardening coating, which have excellent resistance to shocks and guarantee a minimum of scratches (with frequent crashes).
Color. The quality of the optics is important. If you really want something colorful, use grey, green, brown tint lenses. According to ophthalmologists, these tints don't distort color perception. The best option when choosing lenses is to check your color perception, wearing them in natural light.
And yet. Contrary to popular belief, the use of sunglasses is appropriate only in the summer, doctors and specialists working in this field, argue points the driver needs all year round. The essence of their use is not protection from UV and sunlight. Seen better with glasses than with the naked eye, no need to squint and raise yourself premature wrinkles.
