Suddenly the eyes show ripples in vision, and this is usually considered a case of vitreous liquefaction and vitreous opacity. It is usually associated with aging or increased myopia, both of which can cause vitreous degeneration, resulting in vitreous opacity. Vitreous degeneration is the change of the jelly-like shape of the vitreous into a liquid, that is, a jelly-like vitreous that gradually transforms into an aqueous vitreous due to degeneration. If it is with eye rotation or head shaking, it will cause a change similar to water ripples in front of the eyes. However, this change is physiological, usually does not affect the vision, is not painful, and does not bring bad consequences, the clinical is also mainly to observe, and does not take any treatment to intervene.
