Abstract
A method of determining at least one behavioral parameter of a wearer for designing an ophthalmic eyeglass lens includes: a) acquiring a first data set from a first representation of the head of the wearer in three dimensions; b) determining the relative position in space of at least three particular points of the head based on the data set; c) acquiring a second data set from a second representation of the head in a natural posture, including at least one image of each of the three particular points; d) identifying the image of each of the particular points from step b) on the representation of step c); e) deducing information relating to the position and/or to the orientation of the head of the wearer during the determination of the second representation from this identification; and f) determining the behavioral parameter of the wearer based on the information from step e).
