The causes of left eye jumping and right eye jumping are the same and have no specificity. The common causes of eyelid jumping include mental tension, excessive fatigue, eye diseases and so on. 1. Mental tension: In case of high mental tension, the orbicularis oculi muscle around the eye may contract and diastole abnormally, causing eyelid jumping. At this time, you should try to relax as much as possible, which can improve the situation of fluttering eyelids. 2. Excessive fatigue: If long-term eye fatigue, such as long-term reading of cell phones, computers, and insufficient rest, resulting in eye fatigue, may also cause eyelid jumping. 3. Eye diseases: Conjunctivitis, keratitis, dry eye, glaucoma and other eye diseases may also cause frequent eyelid jumping. Eyelid fluttering may also be caused by other reasons, if eyelid fluttering should go to the hospital in time to identify the cause and targeted treatment.
