Abstract: A device and display for demonstrating glare reduction by a polarized lens includes an array of vertically spaced-apart, parallel, transparent elements. Rays of light polarized in a first dimension are directed onto the array from above. An indicium is positioned behind the array. A reflective surface is positioned adjacent a bottom of the array. A polarized lens having a polarization opposed to the first dimension is interposable between a viewer's eye and the array. In use, rays from the polarized light source impinge upon the array, partially pass to the reflective surface and are partially reflected onto the indicium via glare off the array. Rays reflected by the reflective surface are reflected by the array via glare toward the viewer's eye, and rays reflected by the indicium pass thorough the array toward the viewer's eye. An interposition of the polarized lens shields the viewer's eye from the glare.
