ABSTRACT OF THE DISCLOSURE An anti-glare device for a transmission screen includes a layer of transparent material having a front surface and a back surface. The front surface is provided with a saw-toothed profile, while the back surface is bonded to a light-inhibiting device, such as a circular polarizer. A method of reducing glare and echo images is taught involving mounting the anti-glare device a selected distance in front of a transmission screen such that glare due to ambient light is substantially eliminated without producing objectionable echo images.
