UV light can hurt our eyes for a short or long time exposure. UVA, UVB, and UVC are the three subtypes of ultraviolet light.
UVA, like blue light, does not pass through the cornea and instead reaches the retina directly. It is a recognized factor in the emergence of diseases like cataracts that are linked to retinal damage. Some studies suggest that it could possibly be the culprit in macular degeneration.
Even though UVB is blocked by the cornea and does not reach the retina, the outer layer of the eye can still be damaged by UVB, which can cause diseases like pingueculae and pterygia. The eye inflammation known as photokeratitis can be brought on by prolonged exposure to UVB rays.
