While most people know UV rays can damage skin, fewer realize these same rays pose a serious threat to eye health. Prolonged exposure to ultraviolet radiation is a leading cause of cataracts, the clouding of the eye’s natural lens that affects millions worldwide.
What Are UV-Related Cataracts?
Cataracts develop when proteins in the eye’s lens break down and clump together, creating cloudy areas that impair vision. UV radiation accelerates this process by generating free radicals that damage lens proteins. Research shows people with high lifetime UV exposure are up to three times more likely to develop cataracts earlier in life.
The sun’s UV rays are strongest between 10 a.m. and 4 p.m., with intensity increasing at higher altitudes and around reflective surfaces like water, sand, and snow. Even on cloudy days, up to 80% of UV rays can penetrate cloud cover.
Symptoms and Prevention
Early cataract symptoms include blurred vision, increased glare sensitivity, difficulty seeing at night, and colors appearing faded. While age-related cataracts are common after 60, UV-induced cataracts can develop much earlier.
Protect your eyes in a few different ways:
- Wear UV-blocking sunglasses rated for 99-100% UV protection
- Choose wraparound styles for maximum coverage
- Add a wide-brimmed hat for additional protection
- Avoid looking directly at the sun even with sunglasses on
Get a Regular Eye Exam
Annual comprehensive eye exams can detect cataracts in their earliest stages, allowing for timely intervention.
An optometrist generally performs these annual eye exams, and if they determine you need to have a cataract evaluation, that would need to be performed by an ophthalmologist like Dr. Horn.
Dr. Horn will consult with you and determine the lens replacement option that best fits your eye condition and lifestyle. Protect your eyes today and preserve your vision for tomorrow.
If you need a cataract evaluation, contact Vision for Life to schedule your appointment with Dr. Horn. Early detection and professional care are your best defense against UV-related eye damage.
