Abstract
Abstract A dual visor system enables the wearer to use the device as a conventional visor, or to lower a secondary visor to a position below the eyes to provide an aperture to reduce both direct and reflected light entering the wearer's eyes. By providing a roughened upper surface on the lower visor, reflection and glare is further reduced. Both primary and secondary visors may be formed of either opaque or translucent materials in order to either block or reduce light passage to the eyes as desired.
