Clinically reviewed · Last reviewed 2026-06-13
What it is
An eyelid twitch is a brief, involuntary fluttering or spasm of the eyelid muscle, usually in one eye. It is very common, almost always harmless, and usually settles by itself within a short time.
Common symptoms
The twitch is usually mild and intermittent.
- A repeated fluttering or twitching of the upper or lower eyelid
- A twitch that comes and goes over hours or days
- Usually affecting just one eye
- No pain and no effect on vision
Common triggers
Eyelid twitches are often linked to tiredness, stress, too much caffeine or alcohol, eye strain, and dry eyes. Reducing these triggers usually helps the twitch settle.
When to see a clinician
Most twitches need no treatment and ease with rest, less caffeine, and managing eye strain or dry eyes. See a clinician if the twitch lasts more than a few weeks, makes the eyelid close completely, spreads to other parts of the face, or comes with drooping or other symptoms.

How do I stop my eyelid twitching?
Getting more rest, cutting down on caffeine and alcohol, managing stress, and treating eye strain or dry eyes usually help an eyelid twitch settle.
