The eyelid presses down on the eyeball when sleeping, and there is a transient blurring of the refractive state. Most of the time, one eye is pressed down by the pillow towel or when sleeping on the stomach, which leads to a transient change of the shape of the eyeball and produces a pseudo-myopic state, and there will be a blurring of the vision. It is also normal if there is more discharge from the eye and the lining is unstable to see things less clearly, but it will return to normal soon. If this happens every time, pay attention to whether there is eyelid pressure such as granuloma, chalazion and so on. Eyelid compression eyes wake up with blurred vision, most cases have no substantial impact on the eyes, but if the eyelid blurring time is longer, persistent state for a long time, to the hospital for further exclusion.
