Abstract

A sunglass lens of a type to be worn by a person includes a plurality of laterally extending, transparent panes disposed one above the other wherein the panes are curved about the face of the wearer in vertical and horizontal planes. One of the panes is unobstructed so as to form an elongate viewing aperture. Longitudinally extending louvers are disposed within each of two other panes in a manner whereby the louvers are arranged in spaced relation one above the other to form partially transparent masking panes above and below the aperture pane. In manufacturing the sunglass lens of the foregoing type a method is provided for tipping the panes upwardly and downwardly progressively above and below the viewing aperture, the tipping becoming progressively increased with displacement from the plane of the viewing aperture pane.
