Abstract: A gel medium containing at least one non-aqueous solvent and a crosslinked polymer resulting from the reaction of a polyfunctional polymer containing at least two carboxyl moieties capable of undergoing crosslinking reactions, the polyfunctional polymer having a molecular weight from 2,000 g/mol to 3,000,000 g/mol, and a crosslinking agent chosen from a polycarbodiimide or a polyaziridine.

Abstract: An electrochromic cell including a chamber including an electrochromic formulation, and at least two electrodes that are part of the same electrochemical cell and that include a conducting material deposited on the inner surface of the chamber. At least one of the electrodes includes a layer of a transparent conductive oxide and a layer including a conductive polymer, the layer including a conductive polymer being the only part of the at least one electrode that is in contact with the electrochromic formulation.

Abstract: An optical device for a wearer intended to form an electrochromic ophthalmic lens, spectacle glasses comprising two such lenses fitted on a frame, and a method for manufacturing such an optical device. The optical device includes at least one electrochromic cell which has a rear shell and a front shell respectively defining for the optical device a backside surface proximal to at least one eye of the 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. One of the front shell and the rear shell includes a mineral glass substrate, and the other one includes an organic polymeric substrate, and the electrochromic cell forms a hybrid mineral-organic ophthalmic lens selected from plano lenses and prescription lenses satisfying a prescription for power correction.
