To provide a vision training device with extremely big merits that a cost can be substantially reduced and maintenance can be just the replacement of a substrate.
The vision training device includes: the operation board 11 of a contour roughly equal to the visual area of a human, which is attached to a column so as to be elevated and lowered; and a plurality of push button switches 12 arranged in a radial or oblique lattice shape of an appropriate array on the operation board 11 and each incorporating a display element 13. The plurality of push button switches 12 each incorporating the display element 13 are turned to units and arranged on respective substrates 14 at predetermined intervals, and the plurality of substrates 14 are arranged at the predetermined intervals to form the radial shape or an oblique lattice. The respective substrates 14 include a main substrate 14-1 for control, to which a sound substrate 14-2 is attached, and the other sub substrates 14-3, they are connected like beads respectively, and the ON-OFF operation of the display elements 13 on the respective substrates is controlled by the main substrate 14-1.
