Myokymia, more commonly known as an eyelid twitch, occurs when the eyelid muscles spasm uncontrollably. An eyelid twitch can develop for a number of reasons and can last anywhere from a few moments to several days, depending on the underlying cause. Eyelid twitches are usually nothing to worry about, though persistent eyelid spasms can signal a more serious underlying condition.

What Causes Eyelid Twitching?

• Stress — The most common cause. Any type of physical or mental stress leads to the release of cortisol, which can stimulate the nervous system in uncharacteristic ways, including causing muscle twitches.
• Fatigue — Your eyelid twitch may be a sign that your body needs more rest.
• Allergies — Itchy, watery, irritated eyes can cause eyelid spasms.
• Dry Eyes — Dry, sore eyes may sometimes lead to an eyelid twitch.
• Eye Strain — Eye muscle fatigue from prolonged reading or digital device use.
• Caffeine — Consuming too much caffeine can over-stimulate the muscles in your eyes.
• Alcohol — Similar to caffeine, excessive alcohol intake can have stimulating effects on eye muscles.
• Nutrient Deficiencies — Deficiency in vitamins B12 or D, or magnesium, can cause an eyelid twitch.
• Blepharospasm — A rare eye condition caused by a neurological problem that leads to uncontrollable facial and eyelid spasms.
• Neurological Disease — Uncommonly, an eyelid twitch can be a symptom of MS, Parkinson's disease, or Bell's palsy.

How to Stop Your Eye Twitch

• Schedule an eye exam to find out what may be causing your eyelid twitch.
• Practice stress-relieving activities such as yoga and deep breathing exercises.
• Use eye drops to alleviate eye allergies or dry eye symptoms.
• Take frequent breaks from the screen and consider wearing computer glasses.
• Limit caffeine and alcohol consumption.
• Speak with your physician about nutritional supplements and to rule out a neurological disorder.
