Do sunglasses cause cancer?

According to the British Physician’s book , Sunglasses can cause cancer, “The gist of his notion is that reducing the amount of ultraviolet (UV) light reaching key areas of the eye could trick the brain into believing that fewer harmful rays have penetrated the body.” According to his research. 

At this point, I see no reason to give up wearing sunglasses, especially as they also reduce risk of cataract and macular degeneration, common causes of age-related loss of vision. Your best defenses against skin cancer are staying out of the sun when it’s at a high angle in the sky, wearing hats and protective clothing, and using sunscreen with an SPF of 30 or higher (apply it at least 15 minutes before going out into the sun and reapply it every two hours). I prefer sunscreens with  Z-COTE, a form of microfine zinc oxide.However, don’t avoid the sun entirely: you need some exposure to optimize levels of vitamin D.
