[0002] Nowadays, people use their eyes for a long time at close range, which causes visual fatigue and myopia and astigmatism. When children's eyeballs are not fully developed, they will have comprehensive problems such as amblyopia and strabismus. Vision training and correction instruments are a kind of medical device that can train the eye muscles by training the ability of the eyeballs to rotate inward and outward, so that the visual axes of both eyes can move continuously to train the three muscles that dominate vision - ciliary muscles, extraocular muscles, and iris muscles. Through coordinated training, the paralysis and stiffness of the above muscles can be relieved, making them strong and flexible, thereby improving the adjustment ability of the eye muscles, and finally achieving clear imaging of objects on the retina and restoring vision.
