What causes eye twitching?

NEWYou can now listen to Fox News articles!

Muscle spasms are very common and can occur in almost every part of your body.

We recently received this email from a concerned viewer:

Dear Dr. Manny,
I've been getting this weird eye twitch that lasts for a few days at a time. What's the deal?
Dianne in Kentucky

Well Dianne, the twitching you feel is actually the involuntary movement of the muscles around your eye – called a spasm.

Muscle spasms can come on suddenly and last for days, weeks, or even months. The good news is, while a twitching eye can be annoying, it’s often harmless.

Some common causes can include:

  • Drinking alcohol or caffeine 
  • Fatigue
  • Irritation of the surface or inner eyelid
  • Physical exertion
  • Smoking
  • Stress

Occasionally, a twitching eye can be an early sign of a chronic movement disorder. If it worsens over time or you start to experience spasms in other parts of your face, make an appointment with your doctor.
