Abstract
668,043. Anti-dazzle spectacles. DOLOMIT SOC. R. L. June 21, 1950 [May 19, 1950], No. 16480/50. Class 97 (i). In anti-dazzle spectacles, for use by vehicle drivers, of the type in which each lens or eyepiece has a metallic anti-dazzle sector, the frame is so constructed that the distance between the lenses can be varied to suit the interpupillary distance of the wearer. As shown, the lenses 1, 2 bearing metallic sectors 3, 4 are in frames 5, 6 connected to parts 7, 8 sliding within a tubular part 9 and clamped in adjusted position by screws 10, Fig. 3. The parts 8, 9 may be of square or other suitable section to prevent rotation during sliding.
