    Abstract: A method of bonding a film (2) to a curved substrate (1) comprises preforming the film by applying a pneumatic pressure difference between two sides of the film and by heating said film. An intermediate shape is then conferred on the film, which is suitable for applying the film against a curved face of the substrate. This application is carried out, on the one hand, by keeping the film in the intermediate shape by means of an adjusted pressure difference applied between the two sides of the film and, on the other hand, by pressing the substrate against the film by means of a movable support (12-14). Such a method is used to obtain a defect-free ophthalmic lens with a film bonded to it.

    Abstract: A method sticks onto a curved surface of a substrate a functional film (4) that has a substantially planar initial shape. To this end, the film (4) is retained on a deformable membrane (1) by connecting means (2) that allow portions of said film to slip relative to the membrane when said membrane is deformed. This reduces stresses that are created in the film by the deformation. The method is adapted for applying a functional film to an ophthalmic lens.

    Abstract: A transparent optical component comprises two sets of cells (1) disposed in respective superposed layers (10, 20). Each cell (1) contains an optically active material, and the cells in each set are isolated from one another by separating portions (2) within the corresponding layer. The cells (1) of one layer are offset relative to the cells of the other layer so as to be located in line with the separating portions (2) pertaining to the other layer. Such optical component exhibits transparency that is improved compared with components having a single layer of cells or cells that are superposed.
