What causes twitching and tremors in the right lower eyelid?

Spasms and tremors of the right lower eyelid may be caused by either physiological or pathological factors, such as trichiasis or conjunctivitis. The specific analysis is as follows:

I. Physiological Factors

Prolonged熬夜 (staying up late), extended screen time on mobile phones or television can lead to excessive eye fatigue, causing eyelid muscle spasms and resulting in ocular discomfort. It is recommended to maintain good eye hygiene in daily life and take regular breaks to look into the distance to relieve eye strain.

II. Pathological Factors

1. Trichiasis

Congenital trichiasis, if left untreated based on individual eye conditions, may cause misdirected eyelashes to irritate ocular nerves during growth, leading to spasms and tremors of the lower eyelid. It is recommended to seek medical treatment at a hospital, such as undergoing surgery for entropion correction.

2. Conjunctivitis

Poor eye hygiene in daily life may result in bacterial infection, viral infection, or exposure to allergens, which can trigger conjunctivitis. If left untreated over a long period, inflammatory factors continuously irritate ocular tissues and may lead to such symptoms. Patients are advised to use medications such as olopatadine hydrochloride eye drops or levofloxacin eye drops under the guidance of a physician.

In addition to the common causes mentioned above, hemifacial spasm cannot be ruled out. It is recommended to visit a hospital for proper diagnosis and targeted treatment. Maintaining good eye hygiene is essential to prevent worsening of ocular discomfort.
