What causes persistent mild twitching of the right upper eyelid, and what should I do about it?

Under normal circumstances, the main causes of persistent mild twitching of the right eyelid include eye strain, mental stress and anxiety, eyelid spasms, facial neuritis, dry eye syndrome, and others. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a reputable hospital. Detailed explanations are as follows:

1. Eye Strain

Prolonged screen time or staying up late can cause sustained tension in the eye muscles and increased nerve excitability, leading to mild twitching of the right eyelid, often accompanied by dry eyes. Reduce screen time, take a 5-minute break every 40 minutes of visual work, perform eye exercises to relax the eye muscles, ensure 7–8 hours of sleep each night, and avoid staying up late.

2. Mental Stress and Anxiety

Chronic psychological stress and emotional anxiety may disrupt nervous system regulation, causing abnormal electrical discharges in the nerves controlling the eyelids, resulting in eyelid twitching. Relieve stress through physical exercise, listening to music, and other relaxation techniques; maintain emotional stability and avoid excessive tension. Psychological counseling may be necessary when needed.

3. Eyelid Spasms

This condition involves unexplained local neurological dysfunction that leads to involuntary contractions of the eyelid muscles, manifesting as frequent, mild twitching that may gradually worsen. Under medical guidance, medications such as mecobalamin tablets, vitamin B1 tablets, or carbamazepine tablets may be prescribed. Additionally, apply warm compresses locally for 15 minutes twice daily.

4. Facial Neuritis

Damaged facial nerves caused by viral infection or exposure to cold may initially present with abnormal eyelid twitching, followed by symptoms such as facial drooping or difficulty closing the eyes. Under medical supervision, antiviral drugs like acyclovir tablets, corticosteroids like prednisone tablets, and vitamin B12 supplements may be used. Avoid exposing the face to cold; wear a mask outdoors.

5. Dry Eye Syndrome

Insufficient tear production or poor tear quality leads to ocular surface dryness, which irritates the eyelid nerves and triggers twitching, often accompanied by foreign body sensation or burning in the eyes. Under medical advice, use artificial tears such as sodium hyaluronate eye drops, polyethylene glycol eye drops, or carboxymethylcellulose sodium eye drops. Avoid prolonged exposure to air-conditioned, dry environments and use a humidifier to maintain indoor moisture.

In daily life, practice scientific eye usage to prevent overstrain; maintain a regular sleep schedule and avoid staying up late; manage emotions and reduce mental stress; keep eyes moisturized and avoid dry, irritating environments; and undergo regular eye examinations to detect ocular issues early.
