What sort of sunglasses should I wear?

Contrary to popular belief, the actual tint (color) of the lens is not as important as the material or coating, which are responsible for UV blocking. It is critical that all UV-A and UV-B rays are blocked: look for your lens to have CSA or ANSI approval to indicate that it provides full UV protection. Wrap-around frame styles are beneficial in preventing UV from reaching the eye around the frame, and when accompanied by a brimmed hat, can provide excellent protection and comfort.
