METHOD FOR BEVELLING AN OPHTHALMIC LENS

摘要

The invention relates to 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 invention comprises 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 said surface image, an initial contour (C0) of said display lens; d) calculating a corrected contour (C1), by correcting the initial contour according to said correction parameter; and e) deriving said bevelling instruction according to said corrected contour.
