Abstract
An anti-dazzle filter (1) comprises a transparent substrate (2) to which are laminated a vertical polariser (3) and a yellow filter (4). The device may be incorporated into sunglasses or into a visor to reduce glare caused by bright sunlight. Alternatively, it may be used to reduce light back-scattered by fog or mist.
