Contact lenses can help people with nearsightedness, farsightedness or astigmatism see better. This vision correction option is an excellent alternative for those who don’t prefer prescription eyeglasses. They are comfortable to wear and provide better peripheral and center vision since they conform to the curvature of your eyes.
Often, patients ask if their contacts can offer protection against harsh UV rays. Learn the answer to this frequently asked question from your local optometrist.
What Can UV Rays Do to Your Eyes?
The sun’s ultraviolet rays can harm more than just your skin. UVA and UVB rays can penetrate your cornea, potentially damaging the lens and retina. Overexposure to these rays can result in various eye problems, from photokeratitis to cataracts and eye cancer. Those who have previously had cataract surgery and with certain eye conditions like glaucoma are at higher risk of developing UV-related eye damage.
Can Contacts Protect Your Eyes From the Sun?
UV-blocking contacts can provide an additional defense against UV rays. Those who prefer contacts over glasses usually find them appealing. After a comprehensive eye exam, your doctor can determine which type of lenses suits you best. According to the FDA, Class 1 UV-blocking contacts can absorb more than 90% of UVA and 99% of UVB radiation.
However, UV-blocking contact lenses can only safeguard the area they are covering. While they can protect the cornea, they don’t shield the entire eye or surrounding skin. They leave your eyelids and conjunctiva exposed to UV rays. It means they can still put you at risk for cataracts, macular degeneration, and various forms of eye and skin cancer.
What Can You Do to Keep Your Eyes Safe?
Before heading outdoors, be sure to wear UV-blocking sunglasses. Even if it isn’t sunny, you should still keep them on. Look for a pair with 100% UVA and UVB protection. Consider investing in high-quality wraparound sunglasses since they keep UV rays from entering through the sides of the frame. Another thing that can protect your eyes from the sun is a wide-brimmed hat.
