UV Rays and Eye Safety

UV Rays and Increase Risk for Eye Diseases like Cataracts, Macular Degeneration

Nebraska Academy of Eye Physicians and Surgeons Offers Tips for Safe Fun in the Sun

Lincoln, NE – It’s summertime, which means the days are longer and people are enjoying more time outdoors. But, along with risks to your skin, UV rays can be dangerous for your eyes. Studies show that exposure to bright sunlight may increase the risk of developing age-related macular degeneration, cataracts and growths on the eye, including cancer.

The good news is sunglasses, hats, and a little bit of knowledge can go a long way to protect your precious vision. That’s why the Nebraska Academy of Eye Physicians and Surgeons is reminding the public of the simple tips to protect their precious vision this UV Safety Awareness Month.

“UV radiation, whether from natural sunlight or indoor artificial rays, can damage the eye’s surface tissues as well as the cornea and lens,” said David Ingvoldstad, MD “Unfortunately, many people are unaware of the dangers UV light can pose to their vision, and this can lead to potentially blinding eye diseases.”

The Nebraska Academy of Eye Physicians and Surgeons offers these tips to protect your eyes from the sun:

  • Wear sunglasses that offer 100% UV protection. Regardless of the cost or color of your shades, make sure they block 100 percent of UV-A rays and UV-B rays and wear them anytime you are outside or driving during the day.
  • Choose wrap-around styles: Ideally, your sunglasses should wrap all the way around to your temples, so the sun’s rays can’t enter from the side.
  • Wear a hat: In addition to your sunglasses, wear a broad-brimmed hat to protect your eyes.
  • Don’t rely on contact lenses: Even if you wear contact lenses with UV protection, remember your sunglasses.
  • Protect your eyes during peak sun times: Sunglasses should be worn whenever outside. It’s especially important to wear sunglasses in the early afternoon and at higher altitudes, where UV light is more intense.
  • Don’t be fooled by clouds: The sun’s rays can pass through haze and clouds. In fact, sun damage to eyes can occur anytime during the year, not just in the summertime.
  • Don’t forget the kids: Everyone is at risk, including children. Protect their eyes with hats and sunglasses. In addition, try to keep children out of the sun between 10 a.m. and 2 p.m., when the sun’s UV rays are the strongest.

“The longer you are outside in bright light, the greater the risk for eye damage,” says Dr. Ingvoldstad “Don’t forget that UV rays can cause eye damage year-round as well, regardless of whether it is sunny or cloudy.”

Excessive exposure to UV light reflected off sand, water or pavement can damage the eyes’ front surface. In addition to cataracts and age-related macular degeneration, sun exposure can lead to lesions and tumors that may require surgical removal. Pinguecula, tiny yellow bumps on the eye, are common from too much UV exposure. They begin on the white part of the eye and may eventually disrupt your vision.

Damage to the eyes from UV light is not limited to the outdoors; it is also a concern with indoor tanning beds. Tanning beds can produce UV levels up to 100 times what you would get from the sun, which can cause very serious damage to the external and internal structures of the eye and eyelids.

Vigorous Exercise May Prevent Vision Loss

Vigorous Exercise May Prevent Vision Loss

Exercise may have yet another benefit – vision protection. In a recent U.S. study, researchers found that vigorous exercise reduced the risk of cataracts and age-related macular degeneration.  The study tracked approximately 41,000 runners for more than seven years. It suggested that people can possibly lessen their risk for these eye diseases by taking part in a vigorous fitness regimen. On average, running 2 to 4 km (1.2 to 2.5 miles) a day reduced the risk by 19% and running more than 4 km a day reduced the risk by 42% to 54%, compared with those who ran less than 2 km a day. It seems exercise could provide similar protective benefits for the eyes as it does for the heart and other bodily systems.

A cataract is a clouding of the eye’s naturally clear lens, your eye becomes like a window that is frosted or yellowed. Cataracts are a leading cause of vision loss, especially as we age. Age-related macular degeneration reduces vision in the central part of the retina. Macular degeneration can cause sudden, severe loss of vision in the middle of your visual field.
