What causes the left eyelid to twitch?

The left eyelid twitching may be caused by excessive fatigue, keratitis, facial neuritis and other reasons. Details are as follows:

1. Excessive fatigue.

Long-term use of electronic devices such as computers, mobile phones, or reading and writing for a long time may lead to excessive eye fatigue and cause left eyelid twitching.

2.

Inflammatory factors in patients with keratitis and keratitis stimulate the orbicularis oculi muscle, which will lead to spasm of the eye muscle fibers, thus causing left eyelid twitching.

3. Facial neuritis

When facial neuritis occurs, abnormal nerves of facial muscles will affect facial linkage movement and facial twitching occurs.
