Ultraviolate
Coating
UV treated lenses protect the human eyes from the damaging UVA and
UVB sunrays. The cornea of the lens is vulnerable to snow blindness,
pterygia, pingueculae, and photokeratitis. UV treated lenses minimize
the effects of these problems.

such as snow blindness and pterygium. These lenses are available
