Method Of Manufacturing An Ophthalmic Lens

摘要

A method of manufacturing an ophthalmic lens comprising: an ophthalmic lens data providing step (S1) during which ophthalmic lens data corresponding are provided, a semi-finished lens blank providing step (S2) during which a semi-finished lens blank is provided, a transfer function determining step (S3) during which the transfer function to be applied to the first optical surface of the ophthalmic lens so as to correspond to the first lens blank surface is determined, an one side lens data calculating step (S4) during which one side lens having second surface that corresponds to the second optical surface calculated by applying the transfer function, a machining step (S5) during which the semi-finished lens blank is machined according to the one side lens data, a deforming step (S6) during which the machined semi-finished lens blank is deformed so as to obtain the ophthalmic lens.

1. Method of manufacturing an ophthalmic lens, the method comprising:
an ophthalmic lens data providing step (S1) during which ophthalmic lens data corresponding to a first (F1) and second (F2) optical surfaces, a thickness and a prism of the ophthalmic lens to be manufactured are provided, a semi-finished lens blank providing step (S2) during which a semi-finished lens blank having a first (SF1) and second (SF2) lens blank surfaces is provided, a transfer function determining step (S3) during which the transfer function (T) to be applied to the first optical surface (F1) of the ophthalmic lens so as to correspond to the first lens blank surface (SF1) is determined, an one side lens data calculating step (S4) during which one side lens data corresponding to a first and second optical surfaces, a thickness and a prism of an one side lens are determined, wherein the first surface of the one side lens corresponds to the first lens blank surface (SF1), the prism and the thickness of the one side lens are substantially equal to the prism and thickness of the ophthalmic lens and the second surface T(F2) of the one side lens corresponds to the second optical surface calculated by applying the transfer function (T), a machining step (S5) during which the semi-finished lens blank is machined according to the one side lens data so as to obtain a machined semi-finished lens blank, a deforming step (S6) during which the machined semi-finished lens blank is deformed so as to transform the first (SF1) and second (T(F2)) surfaces of the machined semi-finished lens blank into respectively the first (F1) and second (F2) optical surfaces of the ophthalmic lens.
