ABSTRACT:
The present device is an overlay member, such as a glass piece, which permits a viewer to see, for instance a work of art, without being distracted by reflected images emanating from the overlay or glass surface. The present overlay has a base member having rough surfaces on both sides and has a coating, or plurality of layers of anti-reflection material such as silicon dioxide and titanium dioxide, which is arranged to reduce image reflection, from the surface, by light interference. The rough surfaces of the base member substantially disperse the reflecting light, which does occur after the reduction by the anti-reflection coating, so that the viewer sees no image reflection.
