<P>PROBLEM TO BE SOLVED: To provide a vision restoration aiding device which enables restoration of vision evenly without dispersion by a training to focus on a target on a stationary eye chart board and has a simplified structure which has less number of parts and omits a movable structure. <P>SOLUTION: The vision restoration aiding device 1 is constituted by providing, for example, three targets 3A, 3B and 3C on three eye chart boards 2A, 2B and 2C. The targets 3A, 3B and 3C are constituted not to overlap each other on a visual axis C1 when the eye chart boards 2A, 2B and 2C are placed vertically at further and closer distances L1 and L2. A trainee for restoring the vision repeats the state in which he/she visually recognizes by focusing on the target 3B on the eye chart board 2B after visually recognizing by focusing the target 3A on the eye chart board 2A on the visual axis C1 and visually recognizes by focusing the target 3C on the eye chart board 2C. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
