What's wrong with my eyes twitching all the time

Many people don't take their eye twitching seriously. Because even if you ignore it, it will return to normal after a while. But what if the eye twitches for a long time? At this time, everyone should pay attention. Because of this situation, it is likely caused by some disease. Because from a certain perspective, the eyes can be said to be an alarm of our body. It will only send out signals when there is a problem with health.

Why do people’s eyelids twitch? What diseases in the human body can it reflect?

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.

Most people only experience twitching of the upper or lower eyelid, but some people will gradually develop constant twitching of the upper and lower eyelids. The facial nerve that controls the eyelid muscles can cause eyelid twitching if it is stimulated at any point along the conduction pathway. The location, range, and degree of eyelid twitching will vary depending on the part of the nerve that is stimulated.

If the stimulus is limited to the nerve endings that control the orbicularis oculi muscle, that is, near the eyelid, then the symptom manifested is simple upper or lower eyelid twitching. If the stimulated area is the main part of the facial nerve in the brain cavity, the twitching range will affect the entire upper and lower eyelids. The most intuitive manifestation is involuntary blinking, which is medically called "blepharospasm".

Eyelid twitching is caused by many factors, and it can also be seen as an alarm for a person's health condition.

A slight eyelid twitch is actually nothing. Eyelid twitching is mainly caused by four factors, including:

One is the physiological stimulation response. Such as tension, fatigue, overuse of eyes, working in strong light or dim light for a long time, using computer for too long, etc., which can make the eyelids weak and twitch involuntarily.

However, the amplitude of such eyelid twitching is very small, and usually only the person himself knows about it. As long as he is away from these stimulating environments and takes proper rest, he will recover.

The second is some psychological reactions. Some examinees who are under too much psychological pressure, children or young adults who have this habit, and patients with certain neurological diseases may all have symptoms of eyelid twitching.

The third is the reflection of some eye diseases on the surface of the eyelids. Keratitis, conjunctivitis, refractive errors, myopia or hyperopia without wearing appropriate glasses can all cause eyelid twitching.

Fourth, the main facial nerves are stimulated or compressed. One of the main reasons is abnormalities in some blood vessels in the brain. When blood passes through the blood vessels, they compress the roots of the facial nerves, causing autonomous twitching of the eye and facial muscles.

In addition, some brain tumors or arteriosclerosis may stimulate the facial nerves and cause violent reactions in the eyes and face.

So, in a sense, eyelid twitching is also an alarm for human health or psychological condition. Especially long-term eyelid twitching must be alert to whether there is any disease in the brain.
