The subject of the invention is an optical training apparatus allowing people with squints to perform exercises to bring their eyes into a normal position, characterised in that this apparatus contains an image transmitter 1, which transmits two light components which can be separated by filtering, a ray splitter 2, which subdivides into two equal parts, by means of a device with mirrors 3, the light coming from the image transmitter, and, on each of the ray paths, a filter 4, 5 which is opaque to one of the light components, so that the image rays containing the other component are projected onto a screen 6, the direction of projection being capable of rotating under the action of the ray splitter so as to change the distance on the screen 6 separating the two images which are each produced by a different light component. <IMAGE> |
