Abstract: A method of manufacturing an optical lens included the following steps: receiving optical data representing at least a characteristic of an optical correction provided by the optical lens; receiving process data representing at least one characteristic of an additive manufacturing method used to manufacture the optical lens, the process data defining at least an equipment involved in the additive manufacturing method; based on the optical data and on the process data, determining manufacturing data usable by an additive manufacturing machine implementing the additive manufacturing method; and—manufacturing the optical lens by the additive manufacturing machine using the manufacturing data. A corresponding system is also described.

Abstract: An eyeglass managing system determines process parameters for manufacturing at least part of an eyeglass including a lens and a frame. In this eyeglass managing system, an electronic system includes: —a receiving unit adapted to acquire lens data describing an initial lens and frame data describing an initial frame; —a processing unit adapted to identify, based on the lens data and on the frame data, modification parameters deriving from the interaction between the initial lens and the initial frame; and—a transmitting unit adapted to transmit a list of proposed modifications based on the identified modification parameters. The receiving unit is further adapted to acquire a response to at least one proposed modification; the processing unit is further adapted to determine, based on the acquired response, process parameters of an additive manufacturing process for manufacturing the lens or the frame.

Abstract: Disclosed is a method for manufacturing an ophthalmic lens to be mounted in a frame, the ophthalmic lens including an optical front face, an optical rear face, and a peripheral edge that surrounds the optical front and rear faces and that has a base portion carrying a fixing unit suitable for attaching the ophthalmic lens to at least a part of the frame, the method includes the steps of: determining a central part of the ophthalmic lens that includes at least one of the optical front face and the optical rear face; determining the peripheral edge with the fixing unit; calculating a planned manufactured device including both the fixing unit and the central part together; and manufacturing, using an additive manufacturing technology, the planned manufactured device in order to form the ophthalmic lens.

Abstract: A method includes: providing lens blank data relating to the first, second and peripheral blank surfaces of the lens blank; providing optical lens data relating to the first, second and peripheral optical surfaces of the optical lens; virtually positioning the optical lens in the lens blank in a position so that at least one of the first optical surface or the second optical surface is included within the lens blank; evaluating a manufacturing prism cost function, the machining prism cost function corresponding to a weighed sum of the first manufacturing prism to be used when blocking the lens blank on the second surface to machine the first optical surface and of the second manufacturing prism to be used when blocking the lens blank on the first optical surface to machine the second optical surface. The positioning and evaluation steps are repeated so as to minimize the manufacturing prism cost function.

Abstract: Method for determining a position of an optical lens member placed on a lens blocking ring (22). A reference system, blocking ring data, and optical lens member surface data are provided. Position parameters are provided defining a position of a reference point of the surface of the lens member with respect to the main plane of the reference system and an orientation, about the main axis of said placed surface at said reference point. The position of the placed surface is determined according to the position parameters. During a repositioning step (S6) the placed surface is virtually translated and rotated. During an altitude determination step (S7) a difference in position between the blocking ring and the placed surface is determined. The repositioning and altitude determining steps (S6, S7) are repeated so as to minimize the difference in position between the blocking ring and the placed surface.
