Patent ID: 7621750

Claim:
A device for demonstrating the reduction of glare by a polarized lens comprising: an array of vertically spaced-apart, substantially parallel, substantially transparent elements, oriented at an angle to the horizontal in a range between 30 and 60 degrees, the angle distinct from a Brewster's angle of the array elements; means for directing rays of light polarized in a first unitary dimension onto the array from a first end thereof; an indicium positioned behind the array; a reflective surface positioned adjacent a second end of the array opposite the first end; and a polarized lens interposable between an eye of a viewer in front of the array and the array, a polarization of the lens substantially opposed to the first unitary dimension; wherein rays from the source of polarized light can impinge upon the array, partially pass therethrough to the reflective surface and partially be reflected onto the indicium via glare off the array; rays reflected by the reflective surface partially reflected by the array via glare thereoff toward the viewer eye; rays reflected by the indicium partially passing thorough the array toward the viewer eye; an interposition of the polarized lens serving to shield the viewer eye at least partially from the glare from the indicium and from the reflective surface.
