Abstract: A non-fogging goggles includes a double lens that consists of a pair of two spaced-apart lenses that have an air interstice therebetween and in which the inner surface of the outer lens is coated with a metal film. The metal coating is preferably made of gold and is vacuum-deposited on the outer lens. The body heat radiated by the user is reflected on the metal film and reduces the temperature differential between the inner lens and the area enclosed by the goggles, thereby preventing fogging of the inner lens. The radiated heat will also contribute in maintaining the temperature of the lens of any corrective eyeglasses worn under the goggles.

Abstract: A mechanism forming the hinges between an eyeglass frame and the lateral temple bars which allows for the rapid adjustment of the vertical alignment of the lens frame in relation to the horizontal axes of the temple pieces. The forward end of each temple piece is split into a stationary half and a sliding half. Each half terminates into a pin or ball which cooperates with a bearing at the edge of the lens frame to form a hinge allowing each temple piece to be folded against the frame. The sliding halves can be moved along the axes of the temple pieces independently from the stationary ones to tilt the hinging axis so as to change the position of the lens plane in relation to the temple pieces.

Abstract: A detachable visor for a motorcycle helmet having a top wall with laterally spaced side wall members that extend downwardly from the lateral edges of the top wall. A laterally extending recess portion is formed in the top wall intermediate its front edge and its rear edge. The recess portion has a downwardly extending rear wall and a pair of laterally spaced downwardly extending side walls. A plurality of snap fasteners have their female portions attached to the rear surface of the rear wall and they are laterally spaced apart from each other so that they mate with the male portion of the snap fasteners that are secured to the outer surface of the forehead portion of a motorcycle helmet. A top wall cover panel is detachably secured to the side walls in the recess portion to form an aerodynamically smooth top wall surface on the detachable visor. An air flow deflector panel extends between the side wall members of the visor and functions to direct air into the interior of the helmet.
