"Eyelid" is called "eyelid" in medicine. There is a thin muscle in people's eyelids, called "orbicularis oculi muscle", which grows in a wheel shape around the eyes, and its contraction causes eyelid contraction. If for some reason, a certain part of the orbicularis oculi muscle fiber suddenly contracts repeatedly, there will be a phenomenon of "eyelid jump", which is called "eyelid tremor" in medicine.
As the saying goes, "the left eye jumps over wealth and the right eye jumps over disaster." However, there is no scientific basis for this statement. "Eyelid jump" is actually a harbinger of a certain disease in the human body.
Eyelid jump is actually an alarm that reflects human health. For the vast majority of people with simple eyelid jump, the common reasons are excessive eye use or fatigue, excessive mental tension and so on. In addition, eye ametropia, myopia, hyperopia or astigmatism, intraocular foreign bodies, trichiasis, conjunctivitis and keratitis can also cause eyelid jump.
Most eyelid beats caused by eye muscle fatigue and mental stress can be recovered by relaxing stress and proper rest. If the eyelid beats due to ametropia, it can usually be relieved by vision correction. If you have an eye disease, you can find an ophthalmologist to cure it. If the eyelid pulsation is aggravated, leading to eyelid spasm or hemifacial spasm, neurosurgeon is needed for treatment.
In human anatomy, eyelids are called "eyelids". There are two kinds of muscles in eyelids. One is called orbicularis oculi muscle, which is shaped like a wheel and surrounds the eyes. The eyelids close when contracting, and the other is called levator palpebrae superioris muscle, which opens when contracting. With the continuous contraction and relaxation of these two muscles, eyes can be opened and closed. Once stimulated by a certain factor, these two muscles will get excited, leading to repeated contraction, even spasm or tremor, so people obviously feel that the eyelids are beating involuntarily and it is difficult to control. This is eyelid jump.
The most common cause of eyelid jump is eye fatigue, or fatigue, mental tension and so on. For example, the computer plays for too long; Use your eyes for too long in strong or weak light; The mental stress before the exam was too great, and the questions were poorly done, which made the eyelids jump involuntarily. At this point, as long as you take a short rest and close your eyes, the symptoms will disappear naturally, and you don't have to be nervous or uneasy. If the patient has ametropia, myopia, hyperopia or astigmatism, and does not wear appropriate glasses, which leads to eyelid jumping, it is just to remind you that you can pay for glasses suitable for your eyesight.
If the above factors are excluded, the eyelids are constantly beating and getting worse, which may be caused by eye diseases. Please ask an ophthalmologist to find the cause carefully for you and give you symptomatic treatment.
