Abstract
A method for producing an instruction for bevelling an ophthalmic lens, with a view to mounting same in a framework of a spectacle frame into which a bevelled display lens is initially fitted. The method includes the steps of: a) acquiring a correction parameter relative to the play between the framework and the display lens; b) capturing a surface image of the display lens previously removed from the framework; c) determining, on the surface image, an initial contour (C) of the display lens; d) calculating a corrected contour (C), by correcting the initial contour according to the correction parameter; and e) deriving the bevelling instruction according to the corrected contour.
