Abstract
Abstract The apparatus has a support portion and a holder portion. The support portion includes a stick with two ends. A bifocal segment is coupled to one end of the stick. The holder portion has side walls that clamp onto the eye wire of an eyeglass frame. The holder portion also has arms that clamp the stick to the holder portion. The arms allow the stick and the bifocal segment to move up and down. An eyeglass wearer can install the holder portion onto one of the lower eye wires of the frame, don the frame, and adjust the position of the bifocal segment to a satisfactory position. The bifocal segment position is then measured with the stick. The measurement is used to manufacture the corrective lenses for the frame.
