The left eyelid jumping for two days can be judged as a persistent throbbing of the eye, or blepharospasm. The human eye muscles are innervated by the facial nerve emanating from the brain, and when the part of the facial nerve that exits the brainstem happens to be the intersection of the central and peripheral myelin sheaths, it is more susceptible to vascular compression, which can cause the symptoms of blepharospasm, or eye fluttering. In addition, when patients stay up late for a long time, resulting in excessive eye use or neurological weakness, it can also cause blepharospasm and lead to eye fluttering. It can be treated with medications, such as levofloxacin and rifampin eye drops, as well as increasing sleep time, improving sleep quality, and trying to avoid staying up late. Don’t have too much mental stress in your life to relieve the eye throbbing or make the symptoms disappear. Furthermore, if the throbbing continues for a longer period of time, you need to rule out eye nerve dysfunction and it is recommended to go to the hospital for further eye examination.
