L'invention concerne un appareil permettant de tester la vue comportant un boîtier d'occlusion de la lumière et un viseur relié au boîtier et pourvu d'une lentille avant. Un miroir est monté rotatif à l'intérieur du boîtier derrière la lentille avant. Un affichage d'images est monté mobile à l'intérieur du boîtier. Une lentille auxiliaire est montée mobile à l'intérieur du boîtier et positionnée entre l'affichage d'images et le miroir, de sorte qu'une image affichée sur l'affichage d'images passe à travers la lentille auxiliaire, se réfléchit sur le miroir et passe à travers la lentille avant.
