What is the most important feature to look for in a sunglasses?
The most important feature to look for in a sunglass lens is how much UV radiation it absorbs — you want 100% for maximum protection. Look for sunglasses that protect you from 99% to 100% of both UVA and UVB light. This includes those labeled as “UV 400,” which blocks all light rays with wavelengths up to 400 nanometers. (This covers all of UVA and UVB rays.) Inferior sunglasses can be more damaging to your eyes than wearing no sunglasses at all. When one wears sunglasses the pupil widens; if the sunglasses have poor UV protection, then the eyes are damaged more by the sun’s rays. It is also important to get lenses that are ground rather than punched, to minimize distortion. You may want to consider wraparound sunglasses to prevent harmful UV rays from entering around the frame.
