Abstract

1,100,148. Spectacle lenses. R. RODENSTOCK [trading as OPTISCHE WERKE G. RODENSTOCK] April 19, 1966, No. 17143/66. Heading G2J. In order to determine the required positions of the reading portions of bi-focal lenses, test lenses 1 are mounted in a spectacle frame to be worn by a patient and transparent slides 6, which represent the reading portions, are slidably fixed to the lenses 1 with a non-solidifying adhesive. Each slide 6 carries a central vertical line 7 which indicates the position of the slide with respect to vertical and horizontal lines 4, 5 on the associated lens 1. The slides may be coloured and have refractive power.
