Some Key Tips To Protect Your Eyes From The Sun

By: Dr. John Davidson
There are some key things we all can do to protect our eyes during the summer months, especially with July being National UV Safety Month.

Studies have shown that, in addition to skin cancers, accumulated ultraviolet exposure from the sun can heighten the risk of eye diseases such 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:

1. 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 (like Cipro), some birth control and estrogen pills and certain anti-inflammatory pain relievers, such as ibuprofen (Advil) and naproxen sodium (Aleve).

2. More than half (54 percent) of Americans have light-colored eyes (blue, green or hazel). Yet, only 1 in 3 (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.

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

1. 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% 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.

2. 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.

3. 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.

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

5. 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.

6. 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.

Wearing 100 percent UV-protective sunglasses is one of the easiest and the most important things children and adults can do to protect their eye health. It isn't just about fashion or comfort - it's about preserving your sight!
