Ultraviolet (UV) light is known to inactivate some viruses, and Dr. Phil Rice, virologist at St George’s, University of London believes his findings show UV rays could inactivate the varicella zoster virus, responsible for chickenpox and shingles on the skin before it transmits to another person.
Brief exposure to UV light can cause mutations in the DNA of skin cells, including the host cells for melanoma. Sufficient of mutations can result to skin cancer.
Some people wear sunglass to protect their vision from glare and from harm of the ultraviolet rays emitted by the sun; while some do it to make them look good and enhance their appeal; and others to cover their defective eyes or some unwanted marks around their eyes.
