DEVICE FOR DETERMINING THE DISTANCE BETWEEN THE EYE BALL AND THE INTERNAL FACE OF A CORRECTIVE LENS

摘要

The invention relates to a device for capturing the distance (e) between the front part of a patient's eye ball (4) and the internal face (5a) of a corrective lens (5) fixed to a frame (3) of a pair of glasses, by means of a camera (7) and signal processing means. Said device is characterised in that the frame (3) supports a positioning element (l) which is provided with means (15) on one side thereof for transmitting the transversal image of the distance (e) towards the objective (7a) of the camera (7).
