Eyelid twitching, known as eyelid tremor or eyelid muscle spasm, is a common ocular phenomenon that typically presents as involuntary, intermittent twitching of one eyelid. In most cases, this phenomenon is benign and can be caused by the following factors:
1. Excessive fatigue: Prolonged eye use, insufficient sleep, or extended screen time on computers or mobile devices may lead to eye fatigue, which can trigger eyelid twitching.
2. Lack of sleep: Sleep deprivation can affect the body's normal metabolism and the stability of the nervous system, leading to eyelid twitching.
3. Excessive caffeine intake: Consuming too many caffeinated beverages can stimulate the nervous system and increase the likelihood of eyelid twitching.
4. Eye diseases: Conditions such as conjunctivitis, keratitis, and blepharitis may irritate the nerves around the eyes, causing eyelid twitching.
5. Brain tumors: If located in the facial nerve area, they may compress the nerves and blood vessels, causing facial muscle spasms manifested as eyelid twitching.
6. Poor nutrition: Deficiencies in minerals such as magnesium and potassium, as well as B vitamins, may affect neuromuscular function, leading to eyelid twitching.
