The present invention relates to a sight improvement device. The purpose of the present invention is to provide a sight improvement device, which is conveniently operated and automatically changes diopters of a lens to train the ciliary muscle of a user. To this end, the sight improvement device comprises: a main body forming openings at areas in which eyeballs are positioned; a plurality of lenses having different diopters; a lens assembly having a lens support for supporting the lenses and installed in the main body to be able to move for arranging one among the lenses at the openings; a lens exchange driving unit driving the lens assembly; a lens exchange transmission unit between the lens assembly and the lens exchange driving unit to transmit the driving force of the lens exchange driving unit to the lens assembly; and a control unit controlling the lens exchange driving unit to sequentially increase or decrease the diopters of the lenses arranged on the openings. In addition, the present invention may select even an iris muscle exercise and a rectus exercise with the ciliary muscle exercise. In the case of training the iris muscle and the rectus, an iris muscle training mode and/or a rectus training mode are/is selected. The iris muscle training is performed by intermittently repeating exposure of light in a blackout state and the rectus training is performed by left/right, upper/lower and rotating exercises of the eyeballs as the light moves. Ocular lens units with different diopters may be prepared and installed in the sight improvement device according to a user selection. The edge of the ocular lens unit is desirably composed of an elastic material for wearability of the user. |
