Abstract: Disclosed is a multilayer structure for an electrochromic cell, to a electrochromic cell and an ophthalmic device incorporating the multilayer structure, to corresponding uses of the multilayer structure, and to methods for manufacturing the multilayer structure, the electrochromic cell and the ophthalmic device. The multilayer structure includes:—a transparent flexible substrate including a thermoplastic polymeric film, the flexible substrate having two main surfaces, at least one being configurated to be a barrier to oxygen, water vapor and/or solvents, and—a electrically conductive layer which surmounts the flexible substrate to form a flexible first part of the electrochromic cell, the electrically conductive layer being configured to form an electrode of the electrochromic cell and including a deformable electrically conductive nanostructure. The flexible first part is formed to a curved shape defined by a first curvature including at least one of a cylindrical, toric and spherical curvature.

Abstract: A method for manufacturing an ophthalmic element that comprises a vision base element (12) and a film structure (14) adhered to said vision base element allows limiting or suppressing wrinkles and delaminations. This method implements an auxetic part (27) within a sacrificial film portion (26) that belongs initially to the film structure. In this way, stresses generated in a useful area (24) of the film structure by the sacrificial film portion are reduced. The sacrificial film portion is then removed so that only the useful area of the film structure remains in the ophthalmic element.

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.
