When it comes to protecting your eyes from the sun, most people think of the warm, summer months. However, your eyes are at risk of damage all year long. Ultraviolet (UV) light comes from the sun and artificial sources like tanning beds or lasers, and in addition to sunburn, it can cause eye damage.
The risk of UV damage does not decrease during the cooler seasons or cloudy weather, so whether you are taking a walk on a cool autumn day or skiing in the winter months, harmful UV rays can still damage your eyes. It is important to take daily precautions to protect your eyes during every season.
Ultraviolet Rays Can Damage the Eyes
Ultraviolet radiation is a form of non-ionizing radiation that is emitted by the sun. There are benefits to the exposure of natural sunlight, including the production of vitamin D, a vital nutrient. However, overexposure to UV rays can be harmful to your skin as well as your eyes.
UV light more easily penetrates eye tissues than visible light. Increased exposure to UV rays from the sun can increase your risk of eye disease and other eye related problems. These may include:
- Pinguecula – A protein and fat deposit in the white part (sclera) of the eye. It causes irritation and may affect tear production.
- Pterygium – A growth that forms in the eye. As it grows larger, it can affect vision.
- Cataracts – The lens of the eye becomes cloudy. Over time, cataracts can make vision blurry.
- Cancers of the eyelid including basal cell carcinoma and squamous cell carcinoma.
- Macular Degeneration – Some studies suggest that that prolonged, unprotected sun exposure may be a risk factor for age related macular degeneration (AMD).
People who are on certain medications including tetracycline, fluorouracil, sulfa drugs, birth control pills, and certain antibiotics have a higher risk of sun damage to the their eyes and skin. These medications may cause a condition known as photosensitivity.
