The Reason You Need to Wear Your Shades

Three-quarters of Americans are concerned about potential eye problems from the sun’s ultraviolet rays, yet only 31 percent protect their eyes with sunglasses or other UV-protective eyewear every time they go outside, according to a nationwide survey released May 4th 2016. The report by The Vision Council, based on a survey of more than 10,000 adults, finds 34 percent of adults have experienced symptoms of prolonged UV exposure, such as eye irritation, trouble seeing, and red or swollen eyes.

“UV damage to your eyes can start in as little as 15 minutes,” said Justin Bazan, OD, medical adviser to The Vision Council. “Many Americans have a ‘passive’ relationship with their sunglasses, and they don’t realize the dangerous health consequences that can occur from overexposure to the sun’s rays without the right eye protection.”

The report, “Spare Your Sight: Using Shades for Protection and Style”, shows that even though Americans fear vision loss, taking the protective measure of wearing sunglasses is not a high priority. Sunglasses are often forgotten or just not kept on hand, while the protective value of sunscreen and hats to shield skin from UV damage seems to be better understood and more frequently practiced, according to the survey, Americans were much more likely to identify the long-term effects of the sun on skin – such as skin cancer (51 percent) and sunburn (42 percent) – compared with the serious UV impacts on vision, such as sunburned eyes (31 percent), cataracts (26 percent) or age-related macular degeneration (21 percent).

These knowledge gaps and misunderstandings are putting Americans’ vision health at risk. Dangerous sight-threatening disorders, such as cataracts and macular degeneration, are associated with longer-term eye damage, but short-term effects of UV can be felt after spending a long day outside or even after a few hours of intense, unprotected exposure. These irritating and painful conditions include photokeratitis (sunburn of the eye) and pterygium (a growth on the surface of the eye), and cause eyes to become bloodshot, irritated, swollen, or hyper-sensitive to light.

Americans’ habits and excuses may be to blame – many are only sporting sunglasses when they are outside for two or more hours (39 percent). Additionally, during outdoor activities in which UV-eye protection is vital, (particularly between the hours of 8 to 10 a.m. and 2 to 4 p.m.) Americans are leaving their eyes exposed: only 14 percent are likely to wear sunglasses while watching outdoor sporting events and only 44 percent are likely to wear sunglasses at the beach.

UV radiation is present throughout the year, on sunny days and cloudy ones, too. Further, elements such as water, grass, concrete, and snow can powerfully reflect UV light, which can be virtually as harmful as direct UV.
