The American Academy of Ophthalmology has released results of a Harris Poll, showing a majority of Americans are unaware taking common drugs and having light-colored eyes can make people more vulnerable to UV exposure, a contributing factor to certain eye diseases and conditions.

In support of UV Safety Month, the Pennsylvania Academy of Ophthalmology is reminding people of the importance of protecting eyes from damaging UV rays.

Studies have shown in addition to skin cancers, accumulated ultraviolet exposure from the sun can heighten the risk of eye diseases such as eye cancer and cataracts, a leading cause of blindness worldwide.

Intense UV exposure can also cause temporary blindness known as photokeratitis, while extended sun exposure is linked to growths such as pterygium, or surfer's eye.

To assess how much Americans know about eye health risks posed by UV rays and what people do to protect themselves, the American Academy of Ophthalmology – the world's largest association of eye physicians and surgeons – commissioned a national Harris Poll of more than 2,000 adults.

The results revealed two major gaps in UV safety knowledge:

·One-third of adults use medications that may increase photosensitivity, or increased susceptibility to damage from UV rays. However, 49 percent are unaware or do not believe those medications can cause photosensitivity. These photosensitizing drugs include antibiotics containing tetracycline or floroquinolones (such as Cipro), some birth control and estrogen pills and certain anti-inflammatory pain relievers, such as ibuprofen (Advil) and naproxen sodium (Aleve).

·More than half (54 percent) of Americans have light-colored eyes (blue, green or hazel). Yet, only one in three (32 percent) of those with light eyes and 29 percent of all polled know light eyes are more susceptible to UV damage. While people with eyes of any color can develop UV-related eye diseases, light eyes and sun exposure are associated with an increased risk of rare eye cancers, such as iris and uveal melanomas.

Ophthalmologists recommend all individuals – especially those with increased photosensitivity – wear 100 percent UV-safe sunglasses.

While the survey found that 83 percent of Americans wear sunglasses, only half (47 percent) said they check for a UV protection label before buying them.

Also, less than a third (32 percent) make their kids wear UV-blocking sunglasses.

"I encourage all my patients to wear 100 percent UV-protecting sunglasses," says David Armesto, MD, PAO's Secretary of Public and Professional Information. "Not only can they provide protection from harmful UV radiation from the sun, they are also a good barrier to protect the ocular surface from wind damage and foreign objects. It's important to remember that the environment assaults the eye not just from the front, but from the exposed sides of the eye as well. This is a significant risk factor for developing pterygium and other ocular surface disorders. Having a pair of sunglasses that have broad temples or that wrap around will provide the best protection."

The American Academy of Ophthalmology recommends the following tips to protect the eyes from the sun's harmful ultraviolet radiation:

·Choose glasses that block 100 percent of UV rays. Use only glasses that block both UV-A and UV-B rays and that are labeled either "UV400" or "100 percent UV protection." Don't go by darkness of the lenses, which doesn't indicate strength of UV protection. Close-fitting wraparound styles offer the best coverage.

·Wear sunglasses even if it's cloudy. Damaging UV rays go through clouds and can burn skin and eyes even when the sky is overcast.

·Put a lid on it. Wear a hat with a wide brim as well as sunglasses and sunscreen. Studies have shown hats decrease the risk of eye disease related to extended UV exposure.

·Pills and rays don't always mix. Certain medications may cause increased sensitivity to sunlight, so take extra precautions if using those treatments.

·Watch out for sun, sand and water. When at the beach or in the pool, remember that rays reflected off sand, water or pavement can burn your eyes.

·Don't rely on contact lenses. Contact lenses may have UV protection but cannot protect the entire eye area from burning rays that can increase risk of disease and blindness. Remember your sunglasses, which provide more coverage.

The American Academy of Ophthalmology promotes UV safety throughout the year.

The Pennsylvania Academy of Ophthalmology has been working to preserve and protect vision and eye health for Pennsylvania's residents since 1943. With member physicians throughout the commonwealth, the PAO strives to be the voice of ophthalmology; making efforts to ensure quality eye care on the legislative and regulatory fronts, while building and maintaining relationships with major insurance carriers within the state.
