Below, some advice on how to find sunglasses that will protect your eyes without plundering your wallet.
DON’T FORGET THE CHILDREN Upgrade your children from their Dora and Spider-man toy sunglasses to legitimate shades that offer 98 percent to 100 percent UV protection. Children with light-colored eyes are especially vulnerable to sun damage, said Dr. Duffner. The injury is cumulative, so the earlier children get in the habit of wearing shades, the better off their eyes will be.
If your child plays sports regularly, consider also purchasing sport-specific goggles. Eye injuries are the leading cause of blindness in children, and most of those injuries occur when they are playing basketball, baseball, ice hockey or racket sports.
The National Eye Institute says it believes that protective eyewear could prevent 90 percent of sports-related eye injuries in children.
TEST THOSE OLD GLASSES Reluctant to pop for a new pair of sunglasses? If you already have a favorite pair but don’t know what kind of protection they offer, ask your local eyewear store if they have a UV meter. This device can measure the UV protection of your glasses and help you determine whether you should buy a new pair. “Most opticians have such a meter and can do this very easily,” said Dr. Duffner.
Even if you wear contact lenses that offer UV protection, you’re not in the clear. Contact lenses sit on the cornea in the center of your eyes and so can’t protect the surrounding white area (the conjunctiva) and skin.
“I see many older patients who have growths on the whites of their eyes that were caused by sun damage,” Dr. Bishop said. These yellow bumps, called pinguecula, often lead to eye irritation and dryness and may eventually disrupt vision. To prevent them, adults with contact lenses still must wear sunglasses outdoors.
Lastly, if you wear prescription glasses, you can avoid buying sunglasses by either purchasing clip-ons that attach to your frames or having a UV coating applied to your lenses. Presto, you’ll have two pairs in one.
