Just now I saw a netizen suggesting that eye exercise should be “diligent eye rolling”, which is very undesirable. Myopic patients with vitreous liquefaction and clouding are more common, and patients will feel that there are flying mosquitoes and black shadows floating in front of their eyes. At the same time, regardless of the degree of myopia, the proportion of retinal degeneration is also very high, manifesting as limited retinal thinning. If the vitreous and the retinal degeneration area have close adhesion, the excessive rotation of the eye, causing the vitreous to shake, will pull the retina to cause detachment, so you must avoid diligently turning your eyes, shaking your head back and forth. Slowly moving the eyeball should not be a big problem. Liu Bing, Ophthalmology Department, Air Force General Hospital
