The majority of Americans are unaware that 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.
Studies have shown that, in addition to skin cancer, accumulated ultraviolet exposure from the sun can heighten the risk of eye diseases such as eye cancer and cataracts. Intense UV exposure can also cause temporary blindness known as photokeratitis, while extended sun exposure is linked to growths such as pterygiums, which can result in significant vision loss.
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 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 fluoroquinolones, 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 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:
- 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.
- 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.
Wearing 100% 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! So make wearing sunglasses a priority, especially if you have light eyes, work outdoors, or take certain medications.
