Title: METHOD FOR MANUFACTURING AN OPHTALMIC ARTICLE
Abstract:
The invention provides a method for manufacturing an ophthalmic article comprising a substrate and a functional wafer securely fastened to a first curved face of said substrate, said manufacturing method comprising the steps of providing (101) said functional wafer preformed according to a first desired shape, the preformed functional wafer having a first preformed face intended to be applied on said first curved face of said substrate, said first preformed face being defined by first geometrical characteristics; determining (103) second geometrical characteristics of the first curved face of said substrate to be manufactured according to the first geometrical characteristics of said first preformed face of said preformed functional wafer; manufacturing (104) said first curved face according to the second geometrical characteristics determined; fixing (105) said preformed functional wafer to said manufactured substrate by applying the first preformed face on the first curved face in order to form said ophthalmic lens.
