> **Summary:** Eye twitching (myokymia) is a sudden, involuntary and repetitive contraction of the eyelid muscles, in one or both eyes. It is usually harmless, linked to lack of sleep, stress, fatigue or caffeine, and generally settles on its own within days or weeks.

## Quick Facts
- **Medical name:** Myokymia
- **Usual course:** Resolves on its own within a few days or weeks; sometimes lasts months
- **Vision:** Not affected unless the spasms are severe and long-lasting

## Causes
- **Sleep disturbance:** muscles around the eyes are not rested enough.
- **Stress:** one of the most common causes.
- **Eye fatigue:** long computer or television time, reading in poor light; take a break every 20 minutes at the computer.
- **Caffeine and alcohol.**
- **Vitamin and mineral deficiency:** vitamin B12, vitamin D (needed for calcium absorption and muscle relaxation) and magnesium imbalance.
- **Blepharitis:** eyelid inflammation from blocked oil glands and bacteria.
- **Dry eye:** conjunctival irritation from excessive evaporation or low tear production; caffeine, alcohol, contact lenses and some medications contribute.
- **Eye allergy:** pollen, dust and other antigens; rubbing releases histamine.
- Rarely, nervous system disorders.

## Prevention and Relief
- Get enough quality sleep and reduce stress (relaxation techniques, stress management).
- Cut caffeine and limit screen time.
- Use artificial tears if there is dry eye.
- A balanced diet and supplements if needed.

## When to See a Doctor
- Twitching lasting longer than a few weeks.
- The eyelid closes completely.
- Twitching spreads to other parts of the face.
- Other neurological symptoms (neurological causes are possible).
