发明名称 Production of optical lenses, for spectacles, uses plastics blanks for machining and polishing to the required geometry and surface quality, leaving a thicker edge zone around the circumference for clamping and stabilizing during working
摘要 <p>For production of ophthalmic lenses (32), plastics blanks are used structured to a general or specific prescription. Outer edge of blank is clamped for front (19) and rear (27) surfaces to be machined to give final surface geometry and quality, using grinder and/or lathe followed by smoothing and polishing. During machining, a ring zone (30) is retained with an increased thickness (33) at outer circumference of workpiece (16). The thicker ring zone is for clamping the workpiece during machining and movements, and stabilize the ophthalmic lens for further machining. Shapers are fitted to the ring zone to identify the working axes. Fine marking lines are applied to the lens for lens identification. The finished lens is finally separated from the thicker ring zone.</p>
