Method and an Apparatus for Manufacturing an Optical Lens

Abstract

A method of manufacturing an optical lens, the method comprising the steps of blocking a lens member at a first positioning on a blocker; determining the first positioning of the lens member with respect to the blocker; comparing the first positioning of the lens member with a predetermined positioning in order to determine a positioning error between the first positioning and the predetermined positioning; determining a surface positioning of the surface to be manufactured with respect to the blocker according to the positioning error; and configuring operational parameters of a lens manufacturing tool in order to manufacture a surface according to the determined surface positioning such that the desired optical properties of the optical lens are respected. The invention further relates to an apparatus for manufacturing an optical lens.
