Sunscreens in glasses are five levels ranging from 0 to 4. Filter 0 has a light absorption up to 20% and serves only to very low light conditions. Glasses are recommended for driving, and can never be used at night. Filter 1, from 20% to 56% absorption, you need low light conditions. The filter 2, with an absorption of up to 81% would serve to daily activities or sports in medium light conditions, ie in the fall, winter or early spring. However, ideal filters for sunglasses are 3, up to 91% absorption and can be used in the field or the beach with a strong light or the filter 4 with a take of up to 100% supports any type of light, and recommended in case of a practice in the snow but not driving.
