UV Rays can Lead to Vision Loss and Blindness

Posted by siew_hooigan@hotmail.com on December 22, 2014 at 8:15 AM

Recent studies have shown that without proper eye protection, ultraviolet rays may cause serious eye conditions like cataracts and macular degeneration, eyelid cancers.etc.

Although the eyelid is designed to protect the eye, its skin is exceedingly thin and contains many fragile tissues that may be injured by UV light. Inside the eye, the lens and the cornea, both transparent, filter UV rays, but by doing so for many years, they may become damaged. This is especially true for the lens, which through years of UV absorption, turns yellowish and cataractous.

Cataracts are the leading cause of blindness in the world. Proteins in the eye’s lens unravel, tangle and accumulate pigments that cloud the lens and eventually lead to blindness. Even though cataracts appear to different degrees in most individuals as they age, sun exposure, in particular exposure to UVB, appears to be a major risk factor for cataract development.

So when you're outside, don’t just think about protecting your skin, protect your eyes too!
