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).

Method of determining at least one behavioural parameter

A quality control method for optometric measurements includes the following steps: (a) recording, via computer, a first record () that includes at least one first value of a first identifier (), enabling identification of a glasses wearer (), and at least one other value of another identifier () enabling identification of an optometric apparatus () on a first optometric measuring site (); (b) carrying out at least one optometric measurement () of the wearer; (c) sending, to a second site (), a digital measurement data set () including the optometric measurement result from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record () on the basis of a digital data reference system () and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.

A method for determining at least one value of a customization parameter for a visual compensation device includes the following steps: a) a user () equipped with an electronic terminal () captures at least one image or video sequence; b) telecommunicating the at least one image to a remote-support center (); c) processing the at least one image in order to derive therefrom an instruction to correct or validate the captured image or video sequence; d) telecommunicating the correction or validation instruction from the remote-assistance center () to the terminal () of the user (); e) displaying or emitting an audio or video message using the terminal; f) repeating the preceding steps until a validated image or video sequence is obtained; g) determining a value of the at least one customization parameter.
