Abstract
A lens transmits a maximum 2 percent average intensity of ultraviolet light and transmits a minimum 95 percent average intensity of light in a brightness perception spectrum of the eye. In addition, maximum percentages of violet and/or blue light are transmitted. In some cases, the lens transmits a maximum percentage average intensity of red light while transmitting the minimum 95 percent average intensity of light in the brightness perception spectrum. The lens is incorporated in protective eyewear, especially into eyewear used by medical personnel.
