    Abstract: The invention relates to the sealing of a cellular structure (10) along a periphery that includes forming a furrow (S) in said structure, and depositing a portion (11) of a binding material in contact with the respective edges (B1, B3) of a bearing film (1) and of a sealing film (3) of the structure. The binding material may consist of a glue or a welding material. The binding material is cured for definitively connecting the bearing film and the sealing film along the periphery. Such a method is adapted for tightly closing a flexible cellular structure for the optical functionalisation of an ophthalmic lens, in particular when said structure is cut in a sheet.

    Abstract: The invention concerns a method for producing a transparent optical element (1) including filling cells (10) of the element with a substance having an optical property. It consists in moving an amount of the substance (20) radially on the cells, towards a peripheral edge of the optical element, such that the substance penetrates each cell. Optionally, the cells may be sealed with a film (30) fixed on the partition walls (11) of the cells. The filling and the sealing of the cells may be carried out in a single step of the process.

    Abstract: Un composant optique transparent à cellules (1) remplies de matériau optique est proposé, qui présente une transparence élevée. Les cellules du composant sont remplies selon des niveaux (h1,..., h5) qui varient aléatoirement, et dont les variations sont adaptées pour ne pas provoquer de défaut optique perceptible. Pour cela, les niveaux de remplissage des cellules sont adaptés de sorte que des déphasages subis par des rayons lumineux (R1,..., R5) qui traversent les cellules aient un écart quadratique moyen inférieur au quart de la longueur d'onde (lambda). Un tel composant peut être, en particulier, un verre ophtalmique.
