HOW & WHY TO SELECT A Good Quality Pair OF SUNGLASSES This is what the sun does to your eyes: 1. The skin around the eyes, in particular the eyelids, is made up of a very thin tissue. Over time, repeated UV exposure can lead to wrinkles, age spots, and small skin cancers. 10% of all skin cancers occur on the eyelids! 2. Sun damage can cause a condition called pinguecula, a thickening of the clear thin membrane that covers the white of the eye. This causes raised bumps on the eye, near the cornea, which can become irritated and inflamed. If this thickens and grows over the cornea, it’s called pterygium which obscures vision in that eye. 3. The macula is the part of the retina where we have straight ahead vision and detailed vision. That macula can start to deteriorate, leading to macular degeneration, which causes permanent loss of central and detailed vision. UV light and high energy blue light contribute to this condition. 4. Blue eyed people are more susceptible to macular degeneration and especially need to wear sunlasses to protect the retina. 5. Behind the pupil of the eye is the crystalline lens which focuses light on the retina. When the lens becomes clouded, the resulting condition is cataracts. Exposure to UV contributes to the development of cataracts. Wearing sunglasses and a hat slows the process. 6. A common summertime scenario is a day at the lake or the beach. On the
