Why Is My Eyelid Twitching?

An eyelid twitch (myokymia) is an involuntary spasm of the eyelid muscles. It usually occurs in one eyelid at a time and can last from a few moments to several days. Most of the time it is harmless, but persistent twitching can occasionally signal an underlying issue.

Common Causes

• Stress — The most common trigger. Cortisol released during stress can stimulate muscles to spasm.
• Fatigue — A lack of sleep often leads to eyelid twitching.
• Allergies — Itchy, watery eyes can trigger spasms.
• Dry Eyes — Insufficient tear production can cause discomfort and twitching.
• Eye Strain — Prolonged reading or screen time fatigues the eye muscles.
• Caffeine or Alcohol — Too much of either can over-stimulate the nervous system and muscles.
• Nutrient Deficiencies — Low levels of magnesium, Vitamin B12, or D may be a contributing factor.

When to See Your Eye Doctor

If twitching lasts more than a few days, is accompanied by vision changes, affects other facial muscles, or is causing the eye to close completely, consult your eye doctor. These may indicate conditions like blepharospasm or a neurological issue requiring attention.

How to Stop Eye Twitching

• Reduce stress with relaxation techniques
• Get adequate sleep
• Use lubricating eye drops for dry eyes
• Take regular breaks from screens
• Limit caffeine and alcohol
