ABSTRACT:
Disclosed is a cylindrical lens for use in a pair of sunglasses, comprising a unitary pane of transparent material curved about an axis and having a substantially constant radius such that the lens defines a portion of the wall of a cylinder. The arc length measured from a first distal end along the lens to a second distal end is within the range of about 51/2 to about 7 inches so that the lens covers both eyes of the wearer and effectively shields the eyes from peripheral as well as direct bright light. The lens may have either a uniform thickness throughout, or may taper from a greater thickness in a region centered about the midpoint, generally above the nose of a wearer, to a lesser thickness near the peripheral ends of the lens.
