Abstract
129,893. Jones, F. Oct. 30, 1918. Spectacle Lenses.-The lenses of rimless spectacles and eyeglasses are strengthened at the part b where they are to be secured to the frame. The strengthening is effected either by attaching a reinforcing-member of glass, celluloid, mica ,&c. to the lens, or by leaving the lens thick at b during grinding. When a reinforcing-member is used, the hole c for a screw or rivet may pass through both the member b and the lens, or it may be confined to the member b. the lens being unpierced. The hole in the member b may be screwthreaded.
