Introduction
Persistent twitching of the lower left eyelid may be caused by fatigue, staying up late, mental stress, excessive eye strain, eyelid spasms, or facial nerve inflammation. This can be improved through adequate rest, relaxation, emotional regulation, reduced eye use, and medication. If the twitching lasts more than one week or is accompanied by facial numbness, prompt medical attention is necessary. Chronic sleep deprivation or excessive fatigue can lead to dysfunction in the nerves and muscles around the eyes.
The left lower eyelid twitching continuously may be caused by fatigue, staying up late, mental stress, excessive eye use, eyelid spasms, or facial neuritis. It can be improved through rest, relaxation, emotional regulation, reduced eye strain, and medication. If the twitching persists for more than one week or is accompanied by facial numbness, medical attention should be sought promptly.
1. Fatigue and staying up late: Long-term sleep deprivation or overexertion can disrupt neuromuscular regulation around the eyes, leading to eyelid twitching. It is recommended to ensure 7–8 hours of sleep daily, avoid staying up late, and apply warm compresses to the eye area before bedtime to relieve muscle tension.
2. Mental stress: Anxiety and high stress levels can affect nerve function, causing abnormal contractions of the orbicularis oculi muscle and resulting in eyelid twitching. Listening to music, meditation, and communicating with others can help relieve emotions and reduce stress.
3. Excessive eye use: Prolonged screen time or close-up visual tasks keep the muscles around the eyes in a constant state of tension and fatigue, triggering twitching. Reduce screen time, take breaks every 30 minutes by looking into the distance, and perform eye exercises to promote blood circulation.
4. Eyelid spasms: Abnormal nerve excitation causes involuntary contractions of the orbicularis oculi muscle, manifesting as frequent eyelid twitching, possibly accompanied by eye discomfort or soreness. Under medical guidance, medications such as mecobalamin tablets, vitamin B1 tablets, or diazepam tablets may be used to alleviate symptoms.
5. Facial neuritis: Viral infection or exposure to cold may cause inflammation of the facial nerves, affecting muscle control around the eyes and leading to eyelid twitching, often accompanied by mild facial numbness. Patients may follow medical advice to use medications such as acyclovir tablets, mecobalamin injection, or prednisone tablets to improve symptoms.
Maintain a regular routine to avoid overexertion, use your eyes wisely to reduce ocular strain, eat a balanced diet rich in vitamins, stay emotionally well, and apply warm compresses to the eye area to enhance blood circulation.
