summary

Everyone should have heard that the left eye jump is a blessing, and the right eye jump is a disaster. So when our eyes are jumping, we will start to guess whether there is a good thing or a bad thing. Let's talk about how our eyes keep jumping.

How does the eye jump to return a responsibility all the time

First, there are two kinds of muscles in the eyelid. One is called orbicularis oculi muscle, which is shaped like a wheel and surrounds the eye. When it contracts, the eyelid will close. This orbicularis oculi muscle is controlled by facial nerve. And another kind of eyelid muscle is called levator palpebrae superioris muscle. When it contracts, the eyelids will open. This muscle is controlled by oculomotor nerve.

Second: in these two kinds of muscle tissues of eyelid, orbicularis oculi muscle plays a very important role in protecting the eyeball. It can lubricate and clean the cornea through continuous closure, and make a protective response to any external stimulation. Most people are limited to the upper eyelid or lower eyelid beat, but some people will gradually develop into the upper and lower eyelid twitch.

Third: the facial nerve innervating the eyelid muscle is stimulated at any part of the conduction pathway, which can lead to the eyelid beating. Different parts of the nerve are stimulated, the location, range and degree of eyelid beating are also different. Eyelid beat is caused by many factors, it can also be seen as a human health alarm.  

matters needing attention

People's eyelids are constantly beating, sometimes because the eye nerve is stimulated by the outside world, so there is no need to worry about it.
