Abstract
The invention relates to a method for fitting, in a frame, a progressive ophthalmic lens prescribed for a wearer. It proposes that only the horizontal position of the wearer's pupil be measured on the wearer. From this measurement, and from the total height of the pattern of the frame, the lens is positioned in the frame, and is then machined and fitted into the frame. The invention makes it possible, when fitting lenses, to avoid the errors brought about by the measuring of the height of the wearer's pupil with respect to the frame.
