Check out these 12 tips before purchasing sunglasses, which should be worn year-round to protect your eyes, according to doctors at NewYork-Presbyterian Hospital.
Overexposure to the sun not only wreaks havoc on your skin, but can also damage your eyes. George Cioffi, M.D., chief of ophthalmology at NewYork-Presbyterian/Columbia University Medical Center, and Christopher Starr, M.D., FACS, director of refractive surgery at NewYork-Presbyterian /Weill Cornell Medical Center, offer facts about sunglasses and sun exposure that everyone should know before purchasing their 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, and even cancer of the eyelids.
- Sun damage may contribute to the development of cataracts.
- All protective eyewear should have a side shield protection or wraparound the eye 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, or green lenses all 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 all year-round.
- If you don't have wraparound sunglasses, wear a hat with at least a 3-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.
