"Overexposure to UV [ultraviolet] rays has been linked to a variety of problems, including age-related cataracts and degeneration of the cornea," Dr. Gregory W. Good, an optometrist and association spokesman, said in a news release from the group. "Other disorders that can occur are abnormal growths on the eye's surface and even sunburn of the eyes. These conditions can cause blurred vision, irritation, redness, tearing, temporary vision loss and, in some instances, blindness."

He recommends that people wear quality sunglasses that offer proper UV protection and a wide-brimmed hat whenever they're outside. Some sunglasses,contact lenses, Good noted, contain a UV blocker that helps protect the eyes.
