Summer is just around the corner!
That means it’s time to enjoy picnics and parades; beaches and ballgames; festivals and fireworks. Most of all summer means sunshine. Like most things we need to take the good with the bad when it comes to the rays of the summer sun.
Most people use sunscreen to protect their skin, but often forget to protect their eyes. Studies show that exposure to bright sunlight may increase the risk of developing cataracts and growths on the eye, including cancer.
Tanning beds carry the same risks, so it is equally as important to protect your eyes from indoor UV light as outdoor. Sunlight reflected off sand and water can cause photo keratitis, the condition responsible for snow blindness, so beach- and pool-goers need to be mindful of this and use protection.
“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 Kathryn Green, MD. Too much exposure to UV light can increase the risks of several eye diseases, including cataract, growths on the eye, and cancer. “Diseases like cataracts and eye cancers can take several years to develop, but each time we’re out in the sun without eye protection we put ourselves at risk for these serious disorders.”
Ways to Protect Your Eyes
The American Academy of Ophthalmology conducted a national Sun Safety Survey and found that, when asked, only about half of people who wear sunglasses said they checked the UV rating before they bought their sunglasses.
The Academy recommends the following:
It is also important to protect your eyes from the sun all year-long – even in a gray sky state like Wisconsin. Remember:
UV Light: Good in Moderation for a Good Night’s Sleep
As in nearly everything, there is some evidence that states that UV Light in moderation can be good for our eyes and offer a better night’s sleep. During sleep, our eyes enjoy continuous lubrication and clear out irritants such as dust, allergens or smoke that may have accumulated during the day. “Some research suggests that light-sensitive cells in the eye are important to our ability to regulate wake-sleep cycles,” said Dr. Green. This may be more critical for older adults; people who generally have problems with insomnia. “While it’s important that we protect our eyes from overexposure to UV light, our eyes also need minimal exposure to natural light every day to help maintain normal sleep-wake cycles.”
As you soak up the rays remember to take advantage of the benefits of sunshine while also remembering the UV blocking sunglasses and other precautions when your eyes need it most. Enjoy your summer fun.
