Ultraviolet (UV) radiation from the sun can damage your eyes, not just your skin. Choose sunglasses that block 99% to 100% of both UVA and UVB rays. Opt for wraparound sunglasses or closefitting sunglasses with wide lenses that protect your eyes from every angle. Keep in mind that the color of the lenses and the degree of darkness the sunglasses provide have nothing to do with the sunglasses' ability to block UV rays.
