Eye Twitching: Symptoms, Causes, Treatment, and More

Types of Eye Twitching

There are two types of eye twitching: benign essential blepharospasm and hemifacial spasm. Benign essential blepharospasm is the most common type of eyelid twitching, and usually affects both eyes. It is caused by abnormal functioning of the facial nerve that controls the eyelid muscles. Hemifacial spasm, on the other hand, affects only one side of the face and is caused by irritation or damage to the facial nerve.

In addition to these two types of eye twitching, there are other factors that can contribute to eyelid spasms. These include stress, fatigue, caffeine, alcohol, dry eyes, and certain medications. If you experience frequent or prolonged eye twitching, it is important to consult with an eye doctor to rule out any underlying medical conditions.
