Everyone knows that exposure to UV rays can be dangerous, which is why we wear sunscreen when spending time in the sun. But many people forget that their eyes also need UV protection. Long-term sun exposure can have serious effects on eye health, which is why UV-blocking eyeglass lenses are so important.
Keep reading to learn what UV radiation is, why your eyes need protection from it, some eye conditions linked to UV exposure, the importance of wearing glasses with built-in UV protection, and some additional tips for protecting your long-term eye health.
Why Your Eyes Need UV Protection
Not all the light from the sun is visible to the human eye. The sun also gives off ultraviolet (UV) light. We can’t see it, but because of its high frequency and short wavelength, it can damage the cells in our bodies — including our eyes — over time, even on cloudy days.
There are three types of UV rays: UVA, UVB, and UVC. UVC rays are largely absorbed by the earth’s atmosphere, but both UVA and UVB exposure can accumulate throughout a person’s lifetime, damaging the surface and internal structures of the eyes.
Potential Eye Conditions Linked to UV Exposure
Just as prolonged UV exposure on your skin can cause skin cancer, it can damage your eyes if you don’t have proper UV protection. The following eye conditions have been linked to UV exposure:
- Cataracts: Prolonged UV exposure may increase your risk of developing cataracts, which affect your vision by clouding the lenses.
- Macular degeneration: Macular degeneration is an age-related retinal condition that causes a loss of central vision. Research suggests that UV exposure may contribute to long-term retinal damage.
- Photokeratitis: Photokeratitis is like a painful sunburn on your eyes. It’s commonly caused by sunlight reflecting off the snow or water.
- Pterygium (surfer’s eye): Pterygium is a fleshy, raised bump in the corner of the eye that’s typically caused by excessive UV exposure.
The Importance of Eyeglasses with UV Protection
Not all eyeglass lenses provide complete UV protection. To ensure your eyes are completely shielded from the sun, you should make sure your eyeglasses and sunglasses are made with protective coatings that provide 100 percent UVA and UVB protection.
Remember that darker lenses don’t necessarily provide better UV protection. While lens tint affects brightness, it doesn’t block harmful radiation. Even clear prescription lenses can offer excellent UV protection.
Wearing glasses with UV protection is most important on sunny summer days, in winter when the sunlight reflects off the snow, at the beach or on the water, while playing outdoor sports, and while driving. You should wear them even on overcast days, since UV rays can penetrate the clouds.
Tips for Protecting Your Eyes from UV Damage
If you want to ensure your eyes are protected from UV damage, follow these tips:
- Wear sunglasses with 100% UVA and UVB protection
- If you wear prescription glasses, choose lenses with built-in UV protection
- Wear a wide-brimmed hat for additional protection
- Schedule routine comprehensive eye exams to monitor long-term eye health
