To provide an eye function training device capable of effectively training an eye function corresponding to an eye to be trained.

The eye function training device is equipped with an image display part for displaying an image on an eye to be trained, a moving part for moving the image display part forward and rearward at least in one of the optical axis direction and convergence direction of the eye to be trained, a measuring part for measuring the refractive power of the eye to be trained before the movement of the image display part and also measuring the same during the movement of the image display part, a judge part for comparing the refractive power measured before the movement of the image display part with the refractive power is measured during the movement of the image display part to judge whether the reciprocating movement of the image display past is stopped on the basis of a comparison result and a control part for stopping the reciprocating movement of the image display part when the judge part judges that the reciprocating movement of the image display part is stopped.
