Why does my left lower eyelid keep twitching?

Many people sometimes feel their eyelids twitching unconsciously and out of their control. Some people have their right eyelid twitching, while others often have their left eyelid twitching. So what does the twitching of the left or right eyelids actually indicate? Is it true as the old people say that if the left eye twitches, it means good fortune, and if the right eye twitches, it means disaster, or does it indicate some health problems? Today I will tell you what is going on when your lower left eyelid keeps twitching.

When the facial nerves are compressed or stimulated by blood vessels, it can easily cause the eyelids to twitch.

People often say "left eye twitching means wealth, right eye twitching means disaster". In fact, from a medical point of view, eyelids have nothing to do with a person's wealth or disaster. It is just a disease. In a sense, eyelids can also be seen as an alarm for human health, especially those related to the brain nerves.

When the facial nerves that control the eye muscles are stimulated or compressed, they contract, causing the eyelids (medically called blepharoplasties) to twitch.

There are two kinds of muscles in the human eyelids. One is called the 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 the facial nerve. Another eyelid muscle, the levator palpebrae superioris, contracts to open the eyelid; this muscle is controlled by the oculomotor nerve.

Of the two types of eyelid muscle tissue, the orbicularis oculi muscle plays an important role in protecting the eyeball. It can lubricate and clean the cornea through continuous closure and respond protectively to any external stimulation.

Under normal circumstances, these eye opening and closing activities are controlled by the brain nerves. However, once the facial nerve that controls the orbicularis oculi muscle is stimulated by some external factors, it may act autonomously without following the brain's command, causing the orbicularis oculi muscle to contract repeatedly, or even spasm or tremor. People will clearly feel their eyelids twitching involuntarily. This is eyelid twitching.

After reading the above introduction, I believe everyone has a more scientific understanding of eyelid twitching. It is not what people say that left eye twitching means wealth and right eye twitching means disaster. It is just a signal sent by the body. If the beating is really severe, you must go to the hospital for timely treatment.
