Device and method for measuring objective ocular refraction and at least one geometric-morphological parameter of an individual

A device for measuring objective ocular refraction and at least one geometrico-morphological parameter of an individual, said device comprising:

• at least one first target for stimulating the gaze having a center disposed in a first position so as to stimulate the gaze of the individual in a first posture associated with a first proximity value P1 and a first sighting axis,
• a lighting system comprising at least one luminous source, the lighting system being able to generate at least one lighting beam directed toward the eyes of the individual in the first posture,
• an image capture system,
• a computer,
• characterized in that the measuring device furthermore comprises:
• at least one second target for stimulating the gaze having a center disposed in a second position so as to stimulate the gaze of the individual in a second posture associated with a second proximity value and a second sighting axis,
• an optical return system disposed between on the one hand the second target for stimulating the gaze and on the other hand the image capture system and the lighting system, the optical return system being adapted, in a determined orientation, to return the lighting beam toward the eyes of the individual looking at the second target in a second posture, and in that
• the image capture system is adapted for obtaining a first image acquisition comprising a part of the face surrounding the eyes of the individual in the first posture, the image capture system being adapted for obtaining via the optical return system a second image acquisition comprising a part of the face surrounding the eyes of the individual in the second posture, and
• the computer is adapted for receiving and extracting from said at least one first image acquisition on the one hand a first measurement of at least one geometrico-morphological parameter of the individual in the first posture and on the other hand a first measurement of objective ocular refraction by refraction of the lighting beam on the eyes of the individual in the first posture and the computer being adapted for extracting from said second image acquisition on the one hand a second measurement of a geometrico-morphological parameter of the individual in the second posture and on the other hand a second measurement of objective ocular refraction by refraction of the lighting beam on the eyes of the individual in the second posture.
