What Causes Eye Twitching and Why Does My Eye Twitch?

There are a number of causes of eye twitching that may answer your
question, Why Does My Eye Twitch?

Eye twitching, also known as blepharospasm, is a common but frustrating
eye problem where the upper or lower eyelid jumps and goes into a spasm.
Eyelid twitching has numerous causes, some harmless and others potentially

Someone who can't control eyelid spasms or twitching can find it very
distressing. Often this condition is a simple eye muscle problem, but on
occasion it can represent a severe neurological disorder.

It's important to distinguish that there are three main categories of eyelid twitching:

Benign Eyelid Myokymia (Simple Eyelid Twitching) 

The most common form of eye lid twitching is called benign eyelid myokymia
which is also known as benign eyelid twitching. Patients often describe
this common condition as a twitching or “jumping” of the eye. In fact, it
usually involves only the eyelid.

It’s important to ask yourself the following question: “Is it the eye or
eyelid that’s twitching?" because if the eye itself is moving, that is a
potentially more serious neurological condition called nystagmus.

Do you notice the eyelid movements when looking in the mirror, or have
others have noticed it? Typically, the lid twitching that occurs with
benign eyelid twitching is so subtle that the you notice it, but others
rarely see it. You may feel that the phenomenon causes lid drooping also,
but this is rarely noticeable.

Benign eyelid twitching occurs in otherwise healthy individuals. It
typically occurs on one side, but may alternate sides. It may involve the
upper or lower eyelids. The twitching may occur intermittently for hours,
weeks, or even months.

The cause remains uncertain, but is frequently associated with stress,
lack of sleep, fatigue, eyestrain, dry eye, localized eye irritation,
dehydration and electrolyte imbalances or significant ingestion of
caffeine, alcohol, or nicotine. The condition is usually temporary and

The best treatment is to reduce the precipitating factors. However, in
more symptomatic or persistent cases, drug therapy, supplements, eyedrops,
or botox injections may be indicated.
