许多人都有这样的体验:当你正聚精会神地看书或做别的事情的时候,眼皮会突然跳动起来,要控制也无法控制住。有时是一只眼睛跳动,有时是两只眼睛都跳,有的跳几下就停下来了,有的却连跳不止。一些人由于不了解发生眼皮跳的原因,产生了不必要的精神紧张。甚至受到迷信影响,说什么“右眼跳财,左眼跳灾”等等。那么,究竟是什么原因引起眼皮跳动的呢? Many people have this experience: When you are absorbed in reading or doing other things, the eyelids will suddenly jump and you have to control it and you cannot control it.

Even being influenced by superstitions, he said, “the right eye has to make a fortune and the left eye has a disaster,” and so on. So, what exactly caused the eyelid beating?
