ABSTRACT:
The exchangeable lens eyeglasses of the present invention include a frame including a front preferably formed as a one-piece molded plastic part having a pair of spaced rims each having an upper end and a lower end with a bridge interconnecting the rims. The bridge defines an opening. The eyeglasses further include a pair of lenses with each lens supported by a corresponding rim. Each rim has an abutment surface disposed on one side of its lens and a support rib extending on the other side of its lens and cooperating with the abutment surface to seat that lens. The support rib is discontinuous between the lower end the upper end of its rim adjacent the bridge. The eyeglasses further include a retainer preferably formed as a one-piece molded plastic part which is releasably held by the front and has a component received in the opening. The retainer overlaps both lenses and cooperates with the abutment surface of the rims to capture the lenses. Release of the retainer permits removal of the lenses from the front.
