A method of monitoring the behavior of a cohort group of members, including: a cohort group behavior monitoring step during which the behavior of the members of the cohort group of members is monitored so as to provide behavior data; and a vision information generating step during which vision information relating to the vision of the members of the cohort group is generated based on the monitoring of the behavior data over time.

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.
