tips for purchasing sunglasses
- Check the label for 99 or 100 percent UV protection
- Look for sunglasses that are close-fitting. These will prevent UV rays from filtering in.
- Look for larger lenses or wrap-around sunglasses to prevent light from entering in.
- Don't be misguided by price -- higher priced sunglasses usually reflect fashion or durability, not UV protection.
- Dark-colored sunglasses don't necessarily provide better protection. A chemical coating applied to the lens is responsible for UV protection, not the lens color.
- UV-absorbing contact lenses should not be used as substitutes for sunglasses.
- Children are more prone to sun damage to the eyes because their lenses are clearer.
Studies show that exposure to ultraviolet light can contribute to a number of ocular complications, including: photokeratitis, or "snow blindness"; cataracts; pterygium (a benign, abnormal growth on the eye's surface, which may require surgery if sight is threatened); and macular degeneration. eResearch by Navid Ajamin -- summer 2008
