Abstract: Disclosed is a machine for acquiring images (1) including: a support (10) for optical lens, on one side of the support, a light source (20), on the other side of the support, an image sensor (30) suitable for capturing at least two images of the optical lens illuminated by the light source, viewed from two different angles.

Abstract: Disclosed is eyeglasses equipment (1) including a frame (10), and at least one ophthalmic lens (20) mounted into the frame. The equipment includes a colored interface (30) that is placed between the frame and the lens.

Abstract: Disclosed is a method for generating settings for machining an optical lens, including: a) acquiring a file characterizing the shape to which the optical lens must be machined in order to allow it to be mounted in a spectacle frame; b) decomposing the shape into a plurality of distinct objects, including an exterior envelope inside of which all the other objects are located; c) determining a machining order of the other objects; and d) generating the machining settings depending on the machining order.

Abstract: Disclosed is a method for verifying conformity with a predetermined criterion of use of a spectacle frame intended to receive two ophthalmic lenses, including: a) at least one geometrical, mechanical, and/or structural characteristic is determined and the frame category to which the frame belongs from a set of predetermined spectacle-frame categories is deduced therefrom; b) an outline of at least one of the ophthalmic lenses intended to be mounted in the spectacle frame or of a rim of this spectacle frame is determined; c) the value of each parameter from a list of parameters of the frame is evaluated, considering the frame category of step a); the value of at least some of the parameters being evaluated as a function of the outline determined in step b); d) the conformity of the spectacle frame to the predetermined criterion is deduced from the values of the parameters of the spectacle frame.

Abstract: A method for manufacturing an ophthalmic lens (12), includes a marking step for producing permanent technical marks (24) on the lens, which includes a body (29), a first surface (20) and a second surface (28) opposite the first surface (20); the step of additive manufacturing (110-112) of the body and the first and second surfaces, by depositing a plurality of first predetermined volume elements of a first material having a first complex index of refraction (35), in order to obtain first and second optical surfaces, respectively, of the first and second surfaces; and the step of additive manufacturing (113) of the marks by depositing, during the deposition of a plurality of the first volume elements of the first material, at least one second predetermined volume element of a second material having a second complex index of refraction (30) other than the first complex index of refraction of the first material.

Abstract: Disclosed is a method of determining a guideline for trimming an optical lens to be trimmed in view of its mounting in a spectacle frame in which is mounted at least one reference optical lens, including: removing the reference optical lens; fixing the removed reference optical lens on a support of a machine for acquiring images; acquiring, with an image sensor, at least one first image of the removed reference optical lens; processing each acquired first image in order to deduce therefrom trimming parameters for the optical lens to be trimmed; and defining the trimming guideline as a function of the trimming parameters. Before or after the first acquiring step, a second step of acquiring a second image of the reference optical lens mounted in the spectacle frame, and in the processing step, the trimming parameters are defined as a function also of the second image is included.
