Abstract: The invention relates to a method for determining the shape of a bezel (16) of an eyeglass frame rim (11), comprising: —a step of acquiring the shape of a longitudinal contour of the bezel, —a step of calculating or pointing out a position (θj) of one cross-section (Sj) to be felt along said longitudinal contour, and —a step of feeling at least a part of said cross-section (Sj) by moving a mobile feeler in said bezel.

Abstract: Disclosed is a method for assisting a user in taping an adhesive label to a surface of an ophthalmic lens with an initial contour prior to edge grinding, the method including:—holding of the ophthalmic lens with its initial contour by a holder,—determining, from geometric data for the final contour of the ophthalmic lens to be produced, of a position of the final contour inside the initial contour of the ophthalmic lens, creating a visual aid for the user enabling the latter to apply the adhesive label to the ophthalmic lens with its initial contour prior to edge grinding, such that the adhesive label can be applied inside the final contour.

Abstract: Disclosed is a method for automatically centering an ophthalmic lens, including steps of: —positioning the ophthalmic lens on a holder; —acquiring at least one image of the ophthalmic lens received on the holder by means of a camera; and —processing the image to find the position of an optical center of the ophthalmic lens by means of a processing unit. According to the invention, the ophthalmic lens including several distinct centering markings distributed along a geometrical figure, the step of processing includes: —determining, for at least three of the centering markings, the position of at least one characterization point of each centering mark; and —deducing therefrom the position of the optical center of the ophthalmic lens.

Abstract: The method includes the steps of: providing spectacles including a template eyeglass having a mounting portion inserted in a groove of an arc and being to be replaced by a prescription eyeglass having a step-back portion with the same conformation as the mounting portion; providing a set of visible marks on the template eyeglass independently of the arc; having an outline editor providing a visualization of the template eyeglass provided with the visible marks; determining through observation of the spectacles the location—with respect to the visible marks—of points of the arc from which the template eyeglass projects; entering on the provided visualization the so determined locations of the points of the arc; and outputting from the editor the data representative of an edited outline based on the point locations so entered on the provided visualization, whereby the edited outline is the outline of the shoulder.

Abstract: A method for preparing an ophthalmic lens to be edged based on a presentation lens, includes: fixing a first support a face of the presentation lens, the first support's shape defining a first reference point; positioning the presentation lens by the first support in an optical machine having an image sensor; acquiring, with the image sensor, an image of the presentation lens; determining, on the acquired image, the outline of the presentation lens; positioning a pupillary point relative to the outline; positioning the outline of the presentation lens relative to the ophthalmic lens so the pupillary point is superimposed on a centering point of the ophthalmic lens; and fixing a second support a face of the ophthalmic lens, the second support having a shape defining a second reference point, the second support fixed on the ophthalmic lens so its second reference point is superimposed on the first reference point.
