Recently, I met many patients in the clinic who asked whether turning the eyeballs more can protect their eyesight, and there are really a lot of posts on the Internet about the improvement of eyesight by turning the eyeballs every day. Theoretically, there is no scientific basis for saying that turning your eyeballs more can protect your eyesight. The rotation of the eyeball is controlled by the six extraocular muscles attached to the wall of the eye, while the vision is related to the function of the ciliary muscle, cornea, lens, vitreous body and retinal optic nerve in the eye. In fact, in some cases, excessive rotation of the eyeball can induce the occurrence of some eye diseases. The occurrence of retinal tears commonly seen in clinical practice has been reported in both domestic and international literature to be related to the rotation of the eye, as most retinal tears occur at the location of the attachment point of the extraocular muscles that control the rotational movement of the eye in the wall of the eye, and the occurrence of retinal tears can be accompanied by fundus hemorrhage or retinal detachment, leading to vision loss and, in severe cases, surgery. Of course, not all eye rotations can cause retinal tears, but they are more common in elderly people with vitreous degeneration, people with “flying mosquitoes” in front of their eyes, or people with high myopia, so it is recommended that these people do not consciously rotate their eyeballs more.
