1. A method for determining at least one geometrico-morphological parameter of a subject in a natural posture to determine a vision correction equipment, the method comprising the following steps:
a) placing the subject in a natural posture, in which at least one of the gaze directions of the subject points to a visual target;
b) placing an image capture apparatus between the head of the subject and said visual target on a line linking one of the eyes of the subject and the visual target, the image capture apparatus including a pupil;
c) adjusting the relative posture of the image capture apparatus and the head of the subject in order for the pupil of the image capture apparatus to be positioned close to the gaze direction of at least one of the eyes of the subject;
d) capturing an image of the head of the subject; and
e) deducing the at least one geometrico-morphological parameter from the captured image.
