Sunglasses may be made with either prescription or non-prescription lenses that are darkened to offer protection against bright visible light. Good quality sunglasses should also protect against ultraviolet light. Due to changes in the atmosphere, ultraviolet levels are much elevated than in the past and ultraviolet protection for eyes and skin is even more important. It is possible to have lenses that seem very dark and yet offer little ultraviolet protection. Sunglasses fluctuate greatly and many offer more style than protection.
