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.
