Eye twitching is also known as an eye muscle spasm or involuntary eyelid twitching. The technical terms for eye twitching include Blepharospasm or Myokmia in case you like knowing fun facts like that! Blepharospasm is defined as any uncontrolled eyelid twitching caused by muscle contractions around the eyes.
Eye twitching can occur under the eye or in the upper eyelid and it can affect the right or left eye. Eye twitching causes include Benign Essential Blepharospasm (which isn’t harmful), dry eyes, Tourette’s syndrome and strained eyes. Eye twitching should not be confused with drooping eyes which requires serious medical attention as soon as possible.
