Abstract: A method for fitting virtual glasses including the steps of: —[100] placing a real pair of glasses on a user's face; —[200] measuring the position of said real pair of glasses relative to said user's face by a measuring device; —[300] after removing said real pair of glasses, mapping the user's face using a 3D mapping element; —[400] constructing a 3D model of the user's face and of said virtual pair of glasses; —[500] measuring the ophthalmological parameters of said user from the 3D model of the user's face constructed in step [400].

Abstract: 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.
