Eyelid twitching is also called myokymia. It’s a repetitive, involuntary spasm of the eyelid muscles. Usually, it affects the upper lid, but sometimes it can affect both upper and lower lids at the same time. Most often, eyelid twitching is a mild annoyance that feels like a slight tugging on the eyelid.
Most spasms will last for a few seconds and occur every minute or two. These eyelid twitching episodes are unpredictable, so there’s no telling when one will happen. Twitches might happen on and off for several days and then seemingly disappear.
Most often, twitches are painless and harmless. In some cases, eyelid twitching can be a harbinger for a more severe condition, such as a chronic moving disorder.
There’s no one clear cause of eyelid twitches. They’re rarely a sign of a serious condition, so the root cause generally isn’t investigated. Eyelid twitches can be made worse by any of the following:
• Eye irritation
• Eyelid strain
• Lack of sleep
• Medication side effects
• Physical exertion
• Use of stimulants like caffeine, tobacco, or alcohol
When spasms become chronic, the condition is called benign essential blepharospasm, which means that eyelids will uncontrollably wink or blink. The exact cause of this condition isn’t known, but the eyelid twitching might become worse over time. Some external stimuli are known to increase the severity of eyelid twitching.
The condition can worsen over time and might cause blurry vision and increased sensitivity to light or facial spasms.
