To provide an eyesight recovery training device for clearly photographing an eye in a closed and compact case body.
It is adequate that an eyesight recovery training device has the closed and compact case body in order to obtain a dustproof and sound-shielding effect, and moreover, and internally has a camera for photographing the eye under training and a light source. When the camera and light source are arranged inside the small case body, problems occur, that it is hard to arrange the camera and light source at excellent positions where light paths are not disturbed by internal equipment, so as not to easily photograph the eye due to the shadow of the internal equipment, and the reflection of a transparent plate arranged in an eye piece is made incident to the camera as a ghost, so that the clear image of the eye of the trainee is not obtained. Thus, the camera position is determined so as to allow the light path of the camera for photographing the eye to be the same as the light path of an eyesight training image, and the light source position is determined so as to allow the light path of the light source to be the same as the camera light path. Besides, the transparent plate of the eye piece is attached to make a prescribed angle with the light path of the light source. Then, the eye of the trainee is clearly photographed, which has uniform brightness without the shadow and the ghost.
