How does UVA and UVB radiation affect the eyes?
It is important to be ready for the harmful UV rays from the sun. Everyone knows sunscreen is crucial to protect our skin from sunburn and to prevent premature aging but many of us don’t think about protection for our eyes. The UV light enters the pupil where the rays are absorbed by the lens. Over time the lens begins to degenerate due to the free radicals that are formed when the UV rays are absorbed. Eventually cataracts will form and can interfere with vision. Wearing sunglasses reduces the amount of harmful UV rays the lens absorbs and prevents premature cataracts from forming.
