Abstract
A preparation method includes: acquiring a frame of reference of ophthalmic lens defined at least by a first centering point and by a first orientation direction; acquiring a frame of reference of the rim of the eyeglass frame defined at least by a second centering point and a second orientation direction; acquiring a longitudinal profile representative of the shape of the rim and identified in the frame of reference of the rim; acquiring a curvature parameter or a curvature compensation parameter relating to the camber of the eyeglass frame; and putting the two frames of reference into coincidence, by positioning the two centering points relative to each other and by orienting the two orientation directions relative to each other as a function of the curvature parameter or the curvature compensation parameter so as to define the position and the orientation of the longitudinal profile in the frame of reference of the ophthalmic lens.
