METHOD OF MANUFACTURING AN OPTICAL LENS.

摘要

Method of manufacturing an optical lens, the method comprising: • a lens member providing step (S1) during which a lens member comprising a first surface and a first reference system identified by first markings on the first surface is provided, • a surface data providing step (S2) during which surface data corresponding to a second surface and the position of the second surface relative to the first surface of the optical lens are provided, • a blocking and machining step during which the lens member is blocked and the second surface is machined, • a second markings providing step during which second markings identifying a second reference system of the second surface are provided, • a comparison step during which the relative positions of the first and second surfaces are compared.
