Method and device for manufacturing an opthalmic lens using a photoactive material

摘要

Method for manufacturing an ophthalmic lens (101, 102, 103, 104) comprising:
a) providing a sample (100) with a layer (120) of a photoactive material which can be selectively activated to vary its index of refraction;
b) exposing the layer of the photoactive material to activation radiation (44) and "in situ" providing the sample with a measuring radiation (76) and measuring the resulting refractive index local value of the sample, wherein the activation radiation (44) wave length differs of the measuring radiation (76) and wherein the activation radiation or the measuring radiation is reflected on the sample by a beam splitter (60) and the measuring radiation or the activation radiation respectively is transmitted through the same beam splitter (60) on the sample;
c) repeating step b) if necessary and up to a desired activation level.
