What could be the reason for my right eyelid twitching constantly since this morning?

Generally, persistent twitching of the right eyelid upon waking in the morning may be caused by physiological factors, trichiasis, keratitis, conjunctivitis, or blepharospasm. Specific analyses are as follows:

1. Physiological Causes

Staying up late frequently, excessive fatigue, or consuming too much caffeine may lead to persistent twitching of the right eyelid upon waking. This condition is considered a physiological phenomenon and does not require special treatment. It is recommended to get adequate rest, ensure sufficient sleep, and adjust dietary habits; symptoms will gradually improve.

2. Trichiasis

Trichiasis refers to misdirected eyelashes that grow backward from normally positioned hair follicles, irritating the cornea or conjunctiva and causing discomfort. It is primarily caused by congenital entropion, trauma, or degenerative diseases. Treatment such as epilation of the misdirected lashes may be performed under medical guidance.

3. Keratitis

Keratitis can result from infections caused by bacteria, viruses, fungi, or from inflammation spreading from adjacent tissues to the cornea, leading to this symptom. If caused by bacterial infection, antibiotic eye drops such as ofloxacin ophthalmic solution or tobramycin ophthalmic solution should be used under medical supervision to eliminate pathogens and relieve symptoms.

4. Conjunctivitis

Conjunctivitis may be triggered by pathogenic microorganisms or irritation from chemical substances, sand, or other foreign bodies, resulting in this condition. It is recommended to use sodium hyaluronate eye drops or polyvinyl alcohol eye drops under medical guidance to lubricate the eyes and alleviate symptoms.

5. Blepharospasm

Blepharospasm involves involuntary spasmodic contractions of the muscles around the eyelids and orbit, causing this phenomenon, often accompanied by difficulty blinking or frequent blinking. Adequate rest and local warm compresses are recommended to help relieve symptoms.

In addition, persistent twitching of the right eyelid may also be caused by facial muscle spasms. It is advisable to seek medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment.
