Can UV Rays cause Cataracts?
Every day the sun rises and gives us light to see. A sunrise or sunset can be beautiful to watch, but the sun can also damage your eyesight with ultra-violet radiation, or UVR. Your eye is made up of various layers of tissues. These tissues absorb different wave lengths of UVR. Smaller UVR rays or UVA, are mainly absorbed by the retina, while longer ones, or UVB, are absorbed by the lens and cornea. UVR often damages the tissues of the eye and has been linked to causing cataracts. In order to protect yourself outdoors from UVR damage, doctors suggest that you wear sunglasses with a UV filter to shade your eyes from the potential damage of ultra-violet radiation. For more information, ask your doctor for the best ways to protect your eyesight from ultra-violet radiation.
