There’s nothing worse than trying to focus during the day with a pesky eye twitch that won’t stop flickering. You know what we mean — that repetitive, involuntary spasm of your eyelid muscle that occurs every few seconds for a minute or two.

An eye twitch can be unpredictable. It may last for several days or even longer. It may occur off and on for several days. Then you may not experience any twitching for weeks or even months.

An eye twitch doesn’t hurt, but it sure is annoying. But could it be a sign of a more serious problem?

More annoying than harmful

Eye twitches are common and usually, they aren’t anything to worry about, says oculofacial plastic surgeon, Julian D. Perry, MD. Most of the time, an eye spasm will resolve on its own without any need for medical treatment.

“Many patients worry this may represent a neurologic problem. They worry that something serious is going on, but that’s rarely the case,” Dr. Perry says.

“Several things can cause one or both eyes to twitch and they can last for days to weeks, which can be very frustrating,” he says. “But these types of twitches are rarely a sign of a serious problem.”

Causes for the twitch

The most common culprits behind the dreaded eye twitch, Dr. Perry says, are stress and fatigue.

Other causes of eye twitching include:

• Eye irritation.
• Eye strain.
• Eyes that aren’t straight.
• Eyes that need glasses.
• Medication.
• Use of alcohol, tobacco or caffeine.

To get your eye twitch to calm down, Dr. Perry suggests getting enough rest, cutting back on caffeine and reducing stress as much as possible.

Eye drops also can help, if your eyes need moisture.

When it’s time to see a doctor

If eye twitching seems to be lasting for a long time or is becoming particularly bothersome, Dr. Perry recommends a visit to an eye doctor to make sure nothing more serious going on and to consider treatment options.

If it’s more than a few days and it’s really bothering you, or if you notice any of these four signs, you should seek an evaluation:

1. Symptoms such as weakness, drooping or double vision.
2. Your eyes start to look red.
3. It feels like there’s something in your eye or you’re getting light-sensitive
4. If your vision is changing.

Eyelid twitching can sometimes be a part of spasm conditions affecting the eyes, such as essential blepharospasm or hemifacial spasm. “These disorders were some of the very first indications for Botox® injections, the same medicine that we now use to treat wrinkles,” says Dr. Perry.

Very rarely, eyelid spasms are a symptom of a more serious brain or nerve disorder. In these rare cases, eyelid spasms may be an early warning sign of a chronic movement disorder, especially if the spasms are accompanied by other facial twitches or uncontrollable movements.

“While serious disorders are rare, patients who are finding those benign twitches very annoying can find quick improvement with a few injections,” Dr. Perry says. “So it’s worthwhile to come in for an evaluation if the symptoms are bothersome.”
