Abstract: The invention relates to a method for manufacturing a spectacle lens including a base portion and a plurality of solid optical elements (20) that have refraction properties distinct from those of the base portion and that are embedded in the base portion, comprising:—a step of providing said solid optical elements and a first part (11) of said base portion,—a step of arranging said solid optical elements (20) on the inner face of a first part of said base portion, and—a step of manufacturing a second part of said base portion onto said inner face and said solid optical elements to obtain said spectacle lens.

Abstract: The invention relates to a process for making a mold assembly (10) suitable for molding an ophthalmic lens, comprising steps of: —providing two molding shells (200A, 200B) each having a main surface (202A, 202B) to be placed in front of each other and a peripheral edge (203A, 203B), —providing a closing member (100) in the form of a band, —dropping a strip of glue (300) off around at least a major part of the peripheral edge of each molding shell, and—positioning said closing member around at least a major part of the peripheral edges of the two molding shells.

Abstract: A molding device for casting an optical article with a thermoset resin the optical article defining two opposed main surfaces, one of which being formed by an optical functional wafer, the molding device comprising: —a. a molding element (2) forming a rear or a front part of a casting mold —b. a gasket (3) intended to surround the molding element —c. an initially curved wafer (4) defining a predetermined curvature depending on one of the two main surfaces of the optical article to be molded —d. a closing element (6) defining in a closing position in which the peripheral part of the wafer on the gasket is pinched, a pouring space between the molding element, the gasket and the wafer —e. spacing means (9) interposed between the wafer and the molding element to define an internal volume between the wafer and the closing element, the spacing means, wafer and closing element being configured to form a set hermetic to the resin to be poured into the molding device the closing member occupies a closing position.

Abstract: A molding device includes mold shells and a gasket for manufacturing by molding an ophthalmic lens configured to be worn by a wearer, the mold shells each having a molding face and a peripheral side and the gasket including a closed loop portion sandwiched between the molding faces and remotely to the peripheral sides, thus forming a molding cavity of the ophthalmic lens inside the closed loop portion of the gasket, the gasket including a plurality of elongated positioning members each projecting externally from the closed loop portion and each being fastened on a said peripheral side of at least one of the mold shells, the elongated positioning members each having a respective length which is determined in function of an optical axis characteristic of the wearer.

Abstract: The method includes the use of a closed mold consisting of two shells (2,3) and an annular joint (4), the joint having a hole (19) for filling the mold cavity with a polymerizable material, the introduction of the material occurring after a stage in which an external mechanical effort is exerted in order to bring the shells (2,3) together and before a stage in which the effort is relaxed. In the joint (4), the filling hole (19) includes two sections. A first section extends from the molding cavity to the second section which is wider. The device includes elements (34-40) for exerting an external effort in order to bring the shells (2,3) together and elements for introducing the polymerizable material into the molding cavity.
