important to protect

The lenses that block UV rays are important to protect the delicate part around the eyes, as well as the eyes themselves Ambrosina Skin. Research has shown that spending long hours in the sun without protecting your eyes increases your chances of developing certain diseases of the eyes.

Ideal sunglasses should block 99% to 100% of UVA and UVB rays. Before buying sunglasses, check the label to be sure. The labels that indicate "UV absorption up to 400 nm" (absorption of ultraviolet rays up to 400 nm), or "Meets ANSI UV Requirements" means that the lenses block at least 99% of the UV rays.

Those whose label indicates that they are of "cosmetic" use block around 70% of UV rays. If the label does not say so, do not assume that the lenses provide any UV protection. The darker lenses are not necessarily better because the protection against UV rays comes from an invisible chemical that the lenses have or that is applied to them Ambrosina Skin, and not from the color or darkness of them. Look for an ANSI tag.
