Document Type and Number:
Japanese Patent JP3148791
Kind Code:

Abstract:
PURPOSE: To enable pleasant training in a small space and that in the state close to training by real image, by providing a focus distance adjusting means and a depth adjusting means in sight and visual function recovery training.
CONSTITUTION: A control part 111 requests the setting of distance corresponding to training to a virtual image distance changing part 112 and a depth setting part 113 by a request from a training item selecting part 117, and requests the output of a training pattern to a visible index presenting part 115. The virtual image distance changing part 112 optically changes the distance of a virtual image, and the depth setting part 113 sets the depth by the relation of convergence. A person to be corrected can therefore have pleasant visual training in a small space. The control part 111 can be connected to a tactile stimulation generating part 114 to generate stimulation around the eyes, so that the person to be corrected can easily have visual function recovery massage.
