Method of manufacturing an optical lens

摘要

A method of manufacturing an optical lens, comprising: providing a lens member comprising a first surface and a first reference system identified by engraved markings on the first surface, providing surface data corresponding to a second surface of the optical lens to be manufactured, providing second markings on the lens member defining a second reference system, providing marking positioning error between the second markings and the engraved markings, providing an adhesive tape on the first surface of the lens member, and a manufacturing step during which the second surface of the optical lens is manufactured according to the surface data and the marking positioning error such that the relative position of the first and second surfaces is respected.
