Why is my eye twitching?
General information only. This article explains the basics and is not medical advice. For anything about your own health, talk to a doctor or other qualified professional.
Quick answer
A twitching eyelid, called myokymia, is very common and usually harmless. It’s most often triggered by stress, tiredness, too much caffeine, alcohol, eye strain from screens, or dry eyes. It typically goes away on its own within days to a few weeks.
The twitch is a small, repeated spasm of the orbicularis oculi, the muscle that closes the eyelid. It usually affects the lower lid of one eye and is often more noticeable to you than to anyone looking at you.
Common triggers
| Trigger | Why it matters |
|---|---|
| Stress | One of the most frequent causes |
| Lack of sleep | Tired muscles are more likely to twitch |
| Caffeine | Coffee, tea, energy drinks and some sodas |
| Alcohol and smoking | Both can make twitching worse |
| Screen time and eye strain | Long hours without breaks |
| Dry or irritated eyes | Common with screens, contact lenses, allergies and age |
What usually helps
- Getting more sleep and reducing stress
- Cutting back on caffeine (see how much caffeine is in coffee)
- Following the 20-20-20 rule: every 20 minutes, look at something 20 feet (6 m) away for 20 seconds
- A warm compress on the closed eye
Left eye vs right eye
Folklore in many cultures says a twitching left or right eye means good or bad luck, or that someone is talking about you. Medically, the side doesn’t matter; the causes are the same.
When to see a doctor
Health sources advise seeing a doctor if the twitching:
- Lasts more than a few weeks
- Makes the eyelid close completely or spreads to other parts of the face
- Comes with redness, swelling, discharge or a drooping eyelid
These can point to less common conditions that a doctor can check. Feeling run-down too? Read why you might be tired all the time.
