Abstract: The method consists in introducing into a reactor containing the ophthalmic article and the additive a fluid in supercritical state and maintaining this fluid in the reactor for the time required for incorporating the additive into the ophthalmic article, eliminating the fluid in supercritical state and recuperating the ophthalmic article in which the additive has been incorporated. The invention is applicable to the incorporation of photochromic substances.

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.

Abstract: The component has a set of cells (15) juxtaposed along a meshing of a surface of the component. Each cell contains a substance providing particular optical property to the component. Two neighboring cells are separated by a wall (18) extending perpendicular to the surface. Each wall extends between two ends of the wall that corresponds to nodes (N) of the meshing. Some of the walls are not rectilinear to the surface. An independent claim is also included for an optical element obtained by cutting of a transparent optical component.

Abstract: Un élément optique comprend un composant de base (1) pourvu d'un ensemble de cellules (10) ouvertes sur une face du composant, et un film (2) de fermeture des cellules. Le film est collé sur des extrémités (12) de parois (11) de séparation présentes entre les cellules. Le collage est réalisé en appliquant une pression adaptée de sorte que les extrémités des parois pénètrent dans une couche de matériau adhésif (3) disposée entre le film et l'ensemble de cellules. Une valeur d'indice de réfraction du matériau adhésif est ajustée par rapport à une valeur du même indice pour le matériau des extrémités des parois, afin d'obtenir un élément optique qui présente une transparence élevée.

Abstract: Un composant optique transparent comprend un ensemble de cellules (15) juxtaposées sur une surface du composant. Chaque cellule renferme une substance déterminée pour conférer des caractéristiques optiques particulières au composant, et deux cellules voisines sont séparées par une paroi (18). Certaines parois ne sont pas rectilignes à la surface du composant, de sorte que de la lumière diffractée par les parois ne forme pas d'éclat lumineux ni de scintillement. En particulier, les parois peuvent être courbes ou constituées de segments rectilignes disposés bout-à-bout.
