Abstract
A vision training device includes a main body, a lens unit, a drive motor, and a controller. The lens unit includes a plurality of lenses respectively having different diopter values and a lens holder that supports the lenses. The drive motor moves the lens holder so that one of the lenses of the lens unit is disposed on a line of sight axis. The controller controls the drive motor such that a test lens selected from the plurality of lenses is disposed on the line of sight axis and stores an accommodation time indicating a period of time in which the eye becomes in an accommodated state to the test lens.
