Optical device forming an electrochromic ophthalmic lens, spectacle glasses incorporating it and method for manufacturing the same

A method for manufacturing an optical device including at least one electrochromic cell having a rear shell and a front shell and respectively defining for the optical device a backside surface proximal to at least one eye of a wearer and an opposite front surface, the rear shell and the front shell being provided with at least one pair of transparent electrodes and delimiting a sealed cavity filled with an electrochromic composition, wherein a first one of the front shell and the rear shell includes a mineral glass substrate and the other one includes an organic polymeric substrate, and wherein the electrochromic cell forms a hybrid mineral-organic ophthalmic lens selected from plano lenses and prescription lenses satisfying a prescription for power correction, the method comprising:

• computing and designing said one of the rear shell and the front shell which comprises said organic polymeric substrate;
• and
• assembling said one of the rear shell and the front shell which comprises said organic polymeric substrate, to the other front shell or rear shell to form said electrochromic cell by sealing a periphery of said sealing cavity with an adhesive seal and by filling the same with said electrochromic composition;
• and
• surfacing and/or edging at least said one of the rear shell and the front shell which comprises said organic polymeric substrate.
