12 Things You Should Know Before You Buy Sunglasses

Eye care

NEW YORK (April 2014) — Overexposure to the sun not only wreaks havoc on your skin, but can also damage your eyes. Dr. George Cioffi, chief of ophthalmology at NewYork-Presbyterian/Columbia University Medical Center, and Dr. Christopher Starr, director of refractive surgery at NewYork-Presbyterian /Weill Cornell Medical Center, offer facts about sunglasses and sun exposure that everyone should know before purchasing that next pair.

•    Wear sunglasses year-round. Even on cloudy days the UV index can be dangerously high.

•    Overexposure to the sun can cause damage to the cornea, tissue growth on the surface of eyes, as well as skin  cancer on the eyelids.

•    Sun damage may contribute to the development of cataracts.

•    All protective eyewear should have side-shield or wraparound protection so light cannot enter the eye from side reflections.

•    Check the label. Sunglasses labeled UV400 offer more than 95 percent UV protection, which is the recommended level of protection (not all sunglasses are labeled).

•    People who wear contact lenses that offer UV protection should still wear sunglasses.

•    Sunglasses don't have to be dark to offer protection. Neutral gray, amber, brown, and green lenses can block at least 80 percent of transmissible light.

•    Children's eyes are not able to block UV rays as well as adults' eyes.

•    People with light-colored eyes are at higher risk for sun damage to the eyes and need to protect them year-round.

•    If you don't have wraparound sunglasses, wear a hat with at least a three-inch brim that can block sunlight from overhead.

•    Sunglasses are helpful for preventing the drying effect caused when wind meets contact lenses

•    Small infants should always be shaded from direct exposure to the sun.
