摘要 The disclosure relates to a method for selecting progressive ophthalmic lenses for a given frame and wearer, the progressive ophthalmic lenses having one area for distance vision and one area for near vision, said given frame having two recesses suitable for receiving a progressive ophthalmic lens, respectively, said two recesses defining a recess midplane. The method includes the following steps: a) fitting said wearer with said given frame; b) determining the position of a first point of intersection between a first direction of the gaze of said wearer in a distance vision posture and said recess midplane; c) determining the position of a second point of intersection between the gaze of said wearer in a near vision posture and said recess midplane; d) assessing the distance between said intersection points; and, e) selecting progressive ophthalmic lenses in which the progression length corresponds to said distance assessed between said intersection points.
