UV Radiation: The Invisible Threat to Your Vision

May marks UV Awareness Month, and Prevent Blindness—the nation's leading nonprofit dedicated to eye health—is using this time to spotlight the critical importance of protecting your eyes from ultraviolet (UV) radiation. While most of us understand how UV rays damage our skin, fewer people realize that prolonged UV exposure can cause lasting damage to your eyes as well.

From immediate conditions like photokeratitis (also known as "corneal sunburn") to long-term risks such as cataracts, macular degeneration, and ocular cancers, unprotected eyes are vulnerable to serious and often irreversible harm.

Who’s at Greater Risk of UV-Related Eye Damage?

Certain individuals are more susceptible to UV damage than others. According to Prevent Blindness, you may be at elevated risk if:

• You have light-colored eyes (such as blue, gray, or green)

• You spend extended time outdoors—for work, recreation, or driving

• You’ve had cataract surgery

• You live in high-altitude or sun-intense regions

• You’re taking medications that increase light sensitivity (e.g., tetracycline, sulfa drugs, diuretics, tranquilizers, or birth control pills)

• You have certain retinal conditions

For these groups—and truly for everyone UV protection should be non-negotiable.

What Does UV Do to Your Eyes?

The cumulative effects of UV radiation can lead to the breakdown of essential eye tissues. UV-A rays penetrate deep into the eye, contributing to conditions like cataracts and age-related macular degeneration. UV-B rays are primarily responsible for photokeratitis, a painful, temporary loss of vision caused by overexposure to sunlight (like snow blindness or "welder’s flash").

Over time, UV exposure accelerates the aging of your eyes—reducing visual clarity, comfort, and overall eye health.

The Best Ways to Protect Your Eyes from UV Rays

The most effective way to prevent UV-related eye damage is by combining two simple, everyday practices:

• Wear a wide-brimmed hat when outdoors, especially during peak sun hours (10 a.m. to 4 p.m.)

• Use UV-blocking sunglasses that protect against 99–100% of UV-A and UV-B rays

Look for clear labeling on your sunglasses that guarantees UV protection. Fashion sunglasses or cheap knock-offs may look great, but without UV filtration, they do more harm than good by allowing your pupils to dilate and absorb even more radiation.

And if you wear prescription glasses or work in high-glare environments, you may need additional protection like wraparound frames, photochromic lenses, or melanin-enhanced lenses for better contrast and protection.
