ABSTRACT:
This patent provides an eyesight improving device which improves ocular imaging adjustment functions and is easy to use. A user puts the eyes on eyepiece parts10, and sees a figure displayed on a target12by both eyes or one eye by opening or closing blocking device14. In a state where the user focuses the eye on the figure, the target12is moved from a far point to a near point by target movement device18and is next moved from the near point to the far point, and this is repeated. In this case, the size of the figure is controlled to be changed in proportion to the distance between the eyepiecepart10and the target12. The user can easily concentrate to focus the eye on the figure during the movement of the target12. This training activates the ocular imaging adjustment functions of a ciliary muscle, a pupil, vergences and the like resulting with their improvement.
