Most people develop a minor eyelid twitch at some point in their lives. Although the cause is generally unknown, it may be associated with:

In some cases eye twitching is more than a temporary nuisance. Some people have spasms that occur frequently throughout the day. Symptoms can recur for days, weeks, or even months. That can cause a lot of emotional distress. It can interfere with quality of life.
In its most serious forms, which are relatively uncommon, eye twitching can become chronic. It can cause persistent winking and squinting. If it progresses to the point where you have difficulty keeping your eyes open, it can cause severe vision impairment.
Sometimes, eye twitching can be a sign of eye conditions such as:
Blepharitis (inflammation of the eyelids)

Eye twitching can also be a side effect of certain medications. The most common offenders include drugs used in the treatment of psychosis and epilepsy.

Sometimes the cause of minor eyelid twitch cannot be identified. In almost all cases it is painless and harmless.
