As the saying goes, “The left eye jumps for money and the right eye jumps for disaster”. This ancient saying is widely spread among the people, although there is no scientific basis, but the eyelid jumping is really common. So, what exactly is happening with the eyelid jumping? And what should be taken? The eyelids are anatomically called “eyelids” and there are two muscles within the eyelids, one called the orbicularis oculi muscle and the other called the levator muscle, which are constantly contracting and relaxing to keep the eyes open. The eyes open and close because of their constant contraction and relaxation. When the nerves innervating these two muscles are stimulated by some external or internal factor, the eyelids may flutter or spasm repeatedly. At this point, the person will feel the eyelids jumping involuntarily. There are two types of eyelid fluttering: physiological and pathological. In physiological eyelid fluttering, the episodes are short, usually only a few seconds, and the degree of fluttering is not serious. Most of them are caused by insufficient rest, eye fatigue or eating irritating foods and drugs. This kind of eyelid jumping does not affect health and has nothing to do with luck or misfortune. Generally do not need special treatment, feel the throbbing more frequent, you can close your eyes and rest for a while, or use the belly of your finger to massage gently around the eyes, you can also take the warm towel compress eye approach, the general eyelid throbbing will automatically subside. The pathological eyelid fluttering is more frequent, and lasts longer, the fluttering amplitude, some people even the corners of the mouth, half of the face will follow the twitching, more serious is the facial muscle spasm caused by the eyelid fluttering, which is due to the facial nerve governing the movement of the eyelid muscles by the compression of blood vessels. This kind of eyelid throbbing is difficult to heal on its own, and over time will also cause atrophy of the eyelids and facial muscles, and is likely to be a sign of intracranial disease. Therefore, if the eyelids jump for a long time, and there is a trend of gradual aggravation, you should promptly go to the hospital.
