Most people are aware of the dangerous effects of the sun on skin and many take great care to protect themselves and their children from sunburn and its effects. Few though would give any consideration to the harmful effects of ultraviolet (UV) light on the eyes.There are three types of UV light: UVA, UVB and UVC. UVC is harmless to humans as it is absorbed in the upper layers of the atmosphere and does not penetrate to the earth’s surface. However UVA and UVB are both harmful to the skin and eyes. Most people would use sunglasses to protect their eyes from the sun’s glare but there is more to eye protection than simply donning a pair of stylish dark-lens sunglasses.
