What is the reason for the lower eyelid twitching

Eyelid twitching generally refers to eyelid twitching, which is a very common condition. There are many sayings about eyelid twitching. In addition to some superstitious sayings, people should also pay attention to eyelid twitching. An occasional twitching of the lower eyelid may be caused by some external factors, but if such symptoms occur for a long time, you need to consider whether the disease is involved. What's the matter with the lower eyelid twitching?

1. Facial spasms

Under normal circumstances, our eyelids will twitch. There is also a saying that "left eye twitching means good fortune, right eye twitching means disaster." Generally speaking, the symptoms will disappear after a period of rest or some relief. This kind of eyelid twitching is physiological, so there is no need to be nervous. If eyelid twitching persists for more than a month, you should take it seriously and beware of facial spasm.

2. Symptoms

When the facial spasm is severe, it may develop into a state where the eyes cannot be opened, the corners of the mouth twitch, and in severe cases even the neck twitches involuntarily until half of the face is damaged. Hemifacial spasm is a disease in which the range of facial twitching gradually expands and the discomfort gradually becomes more severe. In the early stages of the disease, it is not easy to distinguish between facial spasm and simple eyelid twitching. Doctors will usually ask patients to observe for a period of time and then check again after three months. After three months, if the eyelid twitching disappears on its own, there is no need to pay special attention to it; if the discomfort is only limited to the eyelids, you should see an ophthalmologist; but if the range of twitching has obviously expanded and the symptoms have worsened, it is most likely hemifacial spasm, and you should go to a neurology department as soon as possible.

3. Eye muscle spasm

This may be related to eye muscle spasm, which refers to the involuntary twitching of the muscles around the eyes, which is what we usually call eyelid twitching. In most cases, the common causes of eyelid twitching are excessive use or eye fatigue, and excessive mental stress, such as operating the computer for too long, using the eyes for too long, and excessive mental stress before an exam. In addition, refractive errors, myopia, hyperopia or astigmatism can also cause eyelid twitching. These symptoms are mainly manifestations of irritation of nerve endings, so the symptoms are often limited to one side of the upper or lower eyelid.
