When selecting sunglasses, do not allow yourself to be misled into thinking that darker lenses necessarily filter out sunlight and protect your eyes better than lighter lenses. There are lighter sunglass lenses that provide 100 percent UV protection. On the other hand, sunglasses that do not block 99 to 100 percent of the light can prove more harmful to eyes than not wearing sunglasses at all. The fact is that dark lenses make your pupils dilate, which is the eyes’ response to allow in more light. If that light is not being properly filtered to block ultraviolet rays, it can inflict more damage. Therefore, be sure the sunglasses you choose specify 99 to 100 percent UV protection on their labels. The message has gotten through that too much sun is bad for the skin. But the damage of ultraviolet rays is not limited to the skin – your eyes are also at risk. Whether you spend time at the beach or just drive or walk outdoors, it is important to protect your eyes by wearing sunglasses with UV ray protection. Larger lenses and wraparound sunglasses with 99 to 100 percent UV protection provide the most benefit by covering more of the eyes and face.
