UV rays not easy on the eyes

According to a recent press release from Prevent Blindness Georgia, prolonged exposure to UV rays can result not only in skin cancer, but also in blindness.

Cataracts, which are the leading cause of blindness worldwide, can be caused by both UV-A and UV-B rays. In the United States alone, more than 20 million people suffer from cataracts, according to Prevent Blindness America.

UV-A rays can penetrate deeply, causing damage to the macula, which is the part of the retina that controls sight in the center of the field of vision. UV-B rays can damage tissues in the cornea and lens. Overexposure to UV-B rays may result in photokeratitis, “corneal sunburn,” which can cause extreme pain as well as temporary vision loss.

UV exposure also can cause pterygium, a tissue growth that forms on the white of the eye and can spread to the cornea, eventually requiring surgery.

To protect eyes from UV rays, wear a wide-brimmed hat or cap and proper UV-rated sunglasses. To offer optimal protection, sunglasses should block 99-100 percent of UV-A and UV-B radiation. When purchasing sunglasses, check for UV protection information; tinting alone does not ensure that eyes will be shielded from harmful rays. Wraparound sunglasses are ideal, as they provide the best and most thorough coverage.

In addition to observing precautions for themselves, parents should make sure their children also wear UV-rated eye protection. By providing unbreakable, well-fitted sunglasses and a hat that shades the face, parents can help prevent UV-related eye problems early on. Sun damage is cumulative, so preventative measures now can minimize future vision loss.
