METHOD OF MANUFACTURING AN OPTICAL LENS.

摘要

Method of manufacturing an optical lens 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 determining an providing step (S4) during which second markings identifying a second reference system of the second surface are determined and provided according at least to optical data representing the refractive properties of the optical lens and to observation data representing observation conditions in which the first and second markings are to be observed.
