Sunglasses, if manufactured correctly, can protect the eye from the harmful affects of Ultraviolet (UV) radiation. There are three bands of UV light: UVA, UVB, and UVC.
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 hrs) but painful problem in the cornea of the eye. Some research has suggested that UVB exposure may play a role in the formation of cataracts.
UVC rays are of little concern since they are absorbed by the upper atmosphere and do not reach the earth's surface.
To best protect the eyes, look for sunglasses that provide at least 98% protection from both UVA and UVB rays. All sunwear carried by Scott P. Feldman, O.D. fit this requirement.
This is one of the most visible reasons why sunglasses (prescription and non-prescription) come in such a variety of styles. Many clothing designers and celebrities have their own lines of sunglasses, and Scott P. Feldman, O.D. carries some of today's hottest styles.

It also plays a role in the fashion arena. Anti Reflective Coating is very helpful on the inside (concave) of the lens where reflection of the eye and images behind you can become a hindrance.
