Abstract

L'invention concerne un dispositif de lunettes à réalité augmentée. Le dispositif comprend, dans l'ordre depuis l'extérieur jusqu'à une position proche de l'œil : un premier élément optique (1) qui permet la position dans la direction de la profondeur de la lumière externe (4) pour passer d'une position A à une position B ; un élément d'écran d'affichage transparent (2) qui émet une lumière d'image (5) contenant des informations d'image et permet à la lumière externe (4) de passer ; et un second élément optique (3) qui permet à la position de la lumière externe (4) dans la direction de la profondeur de revenir de la position B à la position A, et permet à la lumière d'image (5) émise par l'élément d'écran d'affichage transparent (2) d'être projetée dans un œil humain (6), la position de la lumière d'image dans la direction de profondeur étant une position appropriée pour l'œil humain.
