News You Can Use: Top Five Ways to Sunblock Your Eyes This Summer… How to Make Healthy Sunglass Choices

NEW YORK (July 2011) — Like your skin, overexposure to the sun can wreak havoc on your eyes. Sun damage can cause severe conditions such as photokeratitis (sunburn to the cornea), pterygium (tissue growth on the whites of eyes that can block vision), skin cancer of the eyelids and even intraocular malignancies like melanoma. Excessive sun exposure has also been implicated in the development of cataracts and possibly macular degeneration.

“Although everyone should protect their eyes from overexposure to harmful UV rays, there are some groups that are at higher risk. People with retinal disorders, cataract surgery patients, people with light-colored eyes, and those taking medications that increase eye sensitivity to light should take extra steps to protect their eyes from the sun in the summer and all year round,” says Dr. Christopher Starr, an ophthalmologist at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

Dr. Stephen Trokel, an ophthalmologist at NewYork-Presbyterian Hospital/Columbia University Medical Center, adds, “There are strong indications that chronic exposure to the components of sunlight may accelerate aging of ocular tissues. Any protective eyewear should have side shield protection or wrap around the eye so light cannot enter the eye from side reflections.”

Many of us are very good about protecting our skin with high SPF sunblock but we often forget about our eyes. This summer think of your UV-blocking sunglasses as “sunblock for your eyes” and you’ll be doing yourself and your eyes a great service.

Drs. Starr and Trokel offer a five-point checklist to help you choose the best sun protection for your eyes during the summer and all year round:

* Check the UV protection level. UV and sunglass protection is desirable year round, and they should also be used during daylight hours, even through cloudiness and haze. Even on cloudy days the UV index can be dangerously high. Your sunglasses should provide more than 95 percent UV protection and ideally 100 percent (sometimes labeled as UV400 on the glasses).

* Check the lens tint. Most people believe that darker sunglasses provide better protection against the sun, but that is not true. The lens tint should block 80 percent of transmissible light but no more than 90 percent to 92 percent of light; neutral gray, amber, brown or green are good colors to choose from.

* Make sure they block all of the light. Choose sunglasses that wrap all the way around the temples, and/or wear a hat with at least a three-inch brim that can block the sunlight from overhead.

* Wear shades over your contact lenses. People who wear contact lenses that offer UV protection should still wear sunglasses. Sunglasses are helpful for preventing the drying effect most contact lens wearers get, which is caused by wind.

* Buy shades for your children. Children’s eyes are not able to block UV rays as well as adults. For the greatest protection, consider providing UV-protected sunglasses for your children, and remember that the eyes of very small infants should always be shaded from direct exposure to the sun.
