Abstract
A lens reduces eye strain and fatigue due to glare, after images, reflections or other visual noise incident upon an observer of a visual display terminal. The lens includes a light transmitting plastic body having a convex shaped outer surface for deflecting stray angular radiation and a body provided, in combination with, an ultraviolet absorber to block the transmission of ultraviolet radiation, a colored dye to diminish the intensity of any fluorescent light incident upon the lens and to diminish the transmission of either or both green color radiation or yellow color radiation through the lens and a grey dye to reduce the transmission of incident light.
