摘要:
The invention relates to a device for measuring ocular refraction and a geometric-morphological parameter of an individual, comprising: a gaze-stimulating target placed so as to stimulate the gaze of the individual in a posture associated with a proximity value and a sight axis; an illuminating system able to generate at least one illuminating beam in the direction of the eyes of the individual; an image-capturing system; and a computer able to receive at least one first image captured by the image-capturing system. According to the invention, the image-capturing system is able to acquire an image of part of the face surrounding the eyes of the individual, and the computer is able to extract, from the acquired image, a first measurement of a glazing parameter and a first measurement of objective ocular refraction by refraction of the illuminating beam on the eyes of the individual in the given posture.
