Abstract
Abstract An attachment for a telephone handset includes a portion which engages a groove in the handset and which may be rotated along the groove. A lens is mounted in a frame rotatably attached to the portion which engages the handset to allow the lens to be oriented for left or right handed use. A connection between the lens frame and the portion engaging in the handset includes a socket which receives flexible projections for holding the frame in any of several desired orientations. In use, a lens is positioned to provide optical assistance for an operator while simultaneously talking on the telephone.
