Abstract: Disclosed is a method for testing the feasibility of a pair of spectacles, the pair of spectacles comprising an identified spectacle frame. The method includes steps of: a) acquiring a range of values of at least one first parameter relating to a spectacle wearer, in all of which range it is desired to ensure the feasibility of the pair of spectacles, b) acquiring a range of values of at least one second parameter that relates to a spectacle wearer and that is different from each first parameter, in all of which range it is desired to ensure the feasibility of the pair of spectacles, c) confirming, for a characteristic number of values of each second parameter, that the pair of spectacles is feasible whatever the value of each first parameter comprised in its range.

Abstract: The invention relates to a process for marking an optical eyeglass (1) equipped with a surface coating (5) comprising the following steps: A step of detreating by means of a laser beam, so as to locally detreat an area of the optical eyeglass by removing the surface coating (5) until a lower layer (7) of the eyeglass (1) is reached, which layer is located under said coating (5) and made of a material that is different from the surface coating (5), thus forming at least one the detreated zone (6, 11), A step of depositing an ink (9) in the detreated zone (6, 11) in order to form at least one inked pattern (4), so that the ink (9) adheres to the lower layer (7) present at the bottom (10) of the detreated zone (6, 11).

Abstract: Systems and methods for controlling an ophthalmic lens edging machine are disclosed. The ophthalmic lens edging machine uses an edger code to select a macro or speed for a requested lens edging job. A system for creating and using the edger code may include a Lab Management System (LMS), a lens calculation system, and a lens edging machine. An edger code may be generated using lens data received from a lens management system and edging machine information identifying one or target lens edging machines. The edger code comprises a plurality of characters. Each character is associated with a different feature of a requested edging job. The features of the requested edging job may include, for example, one or more of: a material type, a lens thickness, an edge type, a frame type, a lens coating, a lens shape, a lens ratio, a lens treatment, and an edging machine block type.

Abstract: A method of polishing a surface of an optical lens intended to be mounted in a spectacle frame includes: obtaining edging contour data representative of the edging contour of the optical lens so as to be mounted in the spectacle frame; and determining polishing tool trajectory data corresponding to the trajectory of a polishing tool so as to polish the surface of the optical lens only within the edging contour; providing the polishing tool trajectory data to a CNC machine carrying a polishing tool; and polishing, via the polishing tool, the surface of the optical lens based on the polishing tool trajectory data.

Abstract: A set includes a molding device having a molding face having the same shape as a contact face of the blocking device. A removable overlay of rigid material has a first face attached to a first face of the semi-finished optical element and a second face opposite to the first face having the same shape as the contact face of the blocking device, the set being configured for having a first subset configuration in which the second face of the removable overlay is in molding contact with the molding face of the molding device, then a second subset configuration in which the second face of the removable overlay is free and then a third subset configuration in which the second face of the removable overlay is retained in contact with the contact face of the blocking device.
