A method for automatically measuring at least one refractive characteristic of both eyes of a person, includes: a) adjusting at least one position of a person's head, in a reference system connected to an image capture apparatus set up to convert each captured image into a signal representing the image； b) illuminating both eyes with at least one light source, whose position is known within the reference system； c) measuring at least one sight direction parameter connected to the sight direction of the person within a reference system connected to the head thereof； d) capturing at least one retinal reflection image from the light source onto the retina of both eyes； f) determining, from the captured image in Step d), the refractive characteristic of the eyes； and h) storing the sight direction parameter in relation to the predetermined refractive characteristic during the image capture in Step c).
