An eyelid twitch is a general term for spasms of the eyelid muscles. These spasms happen without your control. The eyelid may repeatedly close (or nearly close) and reopen. This article discusses eyelid twitches in general.
The most common things that make the muscle in your eyelid twitch are fatigue, stress, caffeine, and excessive alcohol intake. Rarely, they can be a side effect of a medicine used for migraine headaches.
Once spasms begin, they may continue off and on for a few days. Then, they disappear. Most people have this type of eyelid twitch once in a while and find it very annoying. In most cases, you won’t even notice when the twitch has stopped.
You may have more severe contractions, where the eyelid completely closes. This form of eyelid twitching is called blepharospasm. It lasts much longer than the more common type of eyelid twitch. It is often very uncomfortable and may cause your eyelids to close completely.
Twitching can be caused by irritation of the:
• Surface of the eye (cornea)
• Membranes lining the eyelids (conjunctiva)
Sometimes, the reason your eyelid is twitching cannot be found.
