Does UV light actually damage my eyes?
May 23, 2018
Ultra violet (UV) light comes directly from the sun, but it is also reflected from the ground, water, snow, sand and other bright surfaces. While UV-A rays pass through the eye they impact on the health of the retina, UV-B rays are absorbed in the front half of the eye where they can cause damage.
UV light can cause and lead to such conditions as:
- Macular degeneration- a degeneration of the central portion of the retina which can lead to blindness.
- Cataracts- the clouding of the natural lens of the eye. Exposure to UV-B rays can lead to earlier development.
- Photo-keratitis- an inflammation of the cornea and conjunctiva (white of the eye) like a sunburn. Extreme exposure can lead to snow blindness, a painful but reversible condition.
- Pterygiums- these start as small bumps or growths on the conjunctiva but can grow over the cornea and interfere with vision.
- Skin cancers- certain skin cancers can develop with UV-B exposure on any portion of the face and eyelids.
