ABSTRACT:
Reading glasses are specially constructed to permit them to assume a compact storage condition when not in use. Lightweight half lenses are pivoted to the lower ends of an arched nose bridge which functions as a spring to provide the sole force necessary to maintain the eyeglasses on the nose. The lenses may pivot about pivot pins on the nose bridge through pivot arcs of 90.degree. between the wearing and storage positions. The lenses occupy a common plane in all positions. Notches in the lens edges receive the legs of the nose piece to provide a detent for retaining the lenses in the wearing position.
