    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.

    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.
