This study uses glasses-type rotating prism training machine, with the visual front six meters dynamic visual standard, for visual training. Myopia 1.50D for seven minutes for the training cycle, or according to the degree of myopia set the training time. Prism rotation is to make six eyes outside the muscle pull and follow the movement of the eye to create damage to the image and make the image reorganization, to achieve the integration of school vision for a single image of the visual ability. The use of prism rotation caused by visual movement of the image of the retina to produce asymmetry of the image, but in order to maintain the image in the retina corresponding point, so that six eye muscles must be forced to exercise. Students after the rotation of the prism after visual training, eye muscle relaxation and vision become bright, myopia diopter decreased by an average of 0.50D, the maximum reduction of 0.75D (data after three months of experiment). Continuing training once a week, vision is more stable, the experiment shows enough to provide school children control degree. This study can be used as a method to effectively control the number of visually different children.
