Abstract: Disclosed is a method for determining at least one geometrico-morphological parameter of a subject for determining a vision correction equipment, wherein the following steps are performed: a) determining the height of one of the eyes of the subject (P) relative to a reference horizontal surface; b) placing a visual target in front of the head (HP) of the subject (P) at a predetermined position, this predetermined position being determined taking into account the height of one of the eyes of the subject relative to the reference horizontal surface, determined in step a); c) while the subject gazes at the visual target placed at the predetermined position in step b), capturing an image of the head (HP) of the subject (P) with an image capture apparatus (50); and d) deducing from the image captured in step c) the at least one geometrico-morphological parameter.
