Sunglasses need to be more than a fashion statement

Ophthalmologists at UT Southwestern Medical Center, tracking another parade of cloudless summer days, remind everyone to protect their eyes from the sun.

 The surface of the eye and the cornea are particularly vulnerable to the sun’s rays. “Excessive exposure may increase the risk for the formation of a fleshy tissue over the cornea, some forms of cataract, and possibly macular degeneration,” says Dr. V. Vinod Mootha, a specialist in cornea, external disease, refractive, and cataract surgery.

“Sunglasses should be used by adults and children when outdoors for prolonged periods of time. For eyeglass wearers, polycarbonate lenses, which are thin and shatterproof, offer protection from ultraviolet radiation,” Dr. Mootha says.

UV-B exposure is higher on sunny days (especially at noon) and low-ozone days. 

Dr. Mootha says some sunlight is good for people, but common sense should be a guide for limiting exposure time while minimizing the chance of damage to eyes.
