Abstract
A method of centering a target ophthalmic lens presenting a known shape on a target rimless frame, includes identifying the pupillary point on the presentation lens of a presentation frame identical to the target frame, measuring the pupillary height and the pupillary half-distances of the pupillary points, identifying the optical frame of reference of the target lens, transferring the pupillary height and the pupillary half-distances onto the target lens, and deducing the centering position of the target lens. For the presentation lens presenting an outline different from the outline that the target lens will have after edging, the measurements on the presentation lens are taken in a frame of reference associated with the presentation lens, and the position of the target lens is deduced in a frame of reference associated with the target frame.
