The sun’s rays can do significant harm to your vision. Some of the damage is cumulative and cannot be reversed. Protecting your eyes from the sun and sun damage is essential to preserving your eyesight.
Conditions Caused by Sun Exposure
The suns rays can damage the lens, retina, and other parts of your eye. Some of the eye conditions that are caused or contributed to by sun exposure include:
- Macular Degeneration
- Cancer of the eyeball or skin around the eyes
- Growths on the cornea (pterygia)
- Sunburned cornea (photokeratitis)
- Herpes flare-ups
Protecting Your Eyes from the Sun
Staying out of the sun entirely is impossible and would not be healthy. You can protect your eyes from sun damage by staying indoors between 10:00 a.m. and 4:00 p.m. when possible, and wearing the right sunglasses when you go outside.
In order to protect your eyes, your sunglasses need to block 99%-100% of UV rays (both UVA and UVB) and blue light. Many sunglass styles allow light to come in around the lenses, still harming your eyes. Look for large lenses that fit close to your eyes, wrap-around styles, or glacier glasses.
Children are more susceptible to sun damage because their eyes cannot block as much of the UV rays. Make sure that your child’s sunglasses are labeled as UV protective.
Do not be fooled by overcast days. Even when it is not bright outside, you are still being exposed to harmful rays.
