Playing table tennis can prevent myopia. This is because the important cause of myopia is eye fatigue. When the eyes look at the nearby objects, the curvature of the lens increases in order to enhance the curving ability and make the objects fall on the retina, so as to see the objects clearly; However, when looking at the distant objects, there is no need to adjust. People who have been engaged in close work for a long time are easy to cause visual fatigue because the lens is always in a highly regulated state. At the same time, when looking at the nearby object, the balls of both eyes will gather towards the root of the nose, making the muscles in the eyes oppress the eyeball. After a long time, the axis of the eye will gradually become longer, causing myopia.

While playing table tennis, your eyes must be tightly staring at the fast coming ball, which is shuttle, distant and near, rotating and changeable, so as to keep moving inside the eyeball, enhance blood circulation and improve the function of the ocular nerve, therefore, it can eliminate or reduce eye fatigue and prevent myopia.
