Fashion aside, sunglasses serve a true function — protecting eyes from the
harmful rays produced by the sun. You're probably well aware of the need to
protect your skin from the sun, but it's equally important to protect your eyes.
Ultraviolet Light's Dangers Ultraviolet (UV) radiation consists of invisible
rays from the sun. The three bands of UV light are: UVA, UVB and UVC. UVC rays
are of little concern as they are absorbed by the upper atmosphere and do not
reach the earth’s surface. UVB rays are the ones that burn the skin and can
damage the eyes. Combined with cold wind and snow, UVB has the potential to
cause snow blindness (photokeratitis), a temporary (lasting 12 to 48 hours)
but painful problem in the cornea of the eye.
