  • There you are, minding your own business, when your eye starts to spasm1 out of control. It’s a very annoying feeling which can persist for hours. But is there any cause for alarm? Trinidadians have quite a rich collection of superstitions2 concerning jumping eyes. For instance, if your right eye jumps, you are going to hear good news, and if your left eye jumps, you are going to hear bad news. Superstitions aside, the short answer is that a twitching4 eye is totally fine, although in some exceptional cases it may underlie5 a neurological condition.


    Eye spasm is characterized by the spontaneous contractions6 of muscle without muscular atrophy7 or weakness. You might have experienced an involuntary muscle spasm in your knee or elbow. The same can happen to the orbicularis oculi muscle (the muscle in the face that closes the eyelids9).


    Eye spams are typically unilateral, occurring in one of the lower eyelids. Sometimes, both eyelids may be involved but the fascicular contractions of each eyelid8 is independent of each other. The transient and intermittent10 twitching is semi-rhythmic at a rate of 3-8 Hz.


    In the majority of cases, eyelid spasms11 are no cause for concern. These are usually self-limiting and benign12, so medical intervention13 is typically unnecessary. Very rarely, eyelid myokymia may occur as a precursor14 of hemifacial spasm, blepharospasm, Meige syndrome15, spastic-paretic facial contracture, and multiple sclerosis.



    Stress 压力

    This is the number-one reason for a twitching eye, according to ophthalmologists. When we’re under a lot of pressure, the body releases stress hormones16 (cortisol) which triggers a “fight or flight” response. One immediate17 consequence18 is muscle arousal, which may affect eyelid muscles as well. This may be a good time to see your friends, unwind, or meditate19 in order to reduce the stress that might be causing the twitching eye.


    Fatigue20 疲劳

    Not getting enough sleep or working too much overtime21 may cause your eye to complain. Scientists aren’t sure why, but they’ve found that getting more rest will make the symptoms subside22.


    Dry eyes 眼干涩

    More and more people work office jobs that involve a lot of sitting and staring at a computer screen. This sort of lifestyle can lead to dry eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS). Dry eye syndrome is caused by a chronic23 lack of sufficient lubrication and moisture on the surface of the eye. When our eyes are too dry, they might involuntarily start twitching to keep them moisturized. This repeated blinking can trick the brain into making one or both eyes twitch3 even more. To avoid DES, use eye drops if you use the computer for more than seven hours a day and make sure to look away from the screen at least once every 20 minutes.


    Caffeine and alcohol 咖啡因和酒精

    Caffeine and alcohol have seemingly polar effects on the body. One is a stimulant24 while the other is an inhibitor — but both can bring a twitching eye when used in excess. It’s important to stay hydrated and to avoid real or artificial sugars when this happens.


    Mineral deficiencies 缺乏矿物质

    A jumping eye might be triggered by magnesium25 deficiency. If the twitch persists, it’s a good idea to get your magnesium levels checked with a simple blood test. If you really are magnesium deficient26, you should focus on eating more foods like almonds, oatmeal, or spinach27. You can also take magnesium supplements to meet daily Mg needs.


    Eyelid infection 眼睑感染

    Blepharitis occurs when bacteria infect your eyelids, causing inflammation and redness. This makes the muscles around the eye twitchy. Other symptoms include burning or stinging eyes, dandruff at the base of the eye, and grittiness. The treatment of blepharitis should begin with a visit with your eye doctor to determine the cause of your sore, red, itchy eyelids. Eyelid hygiene28 is very helpful to treat and control blepharitis, and a good place to begin is applying a wet clean warm compress to melt any blocked residue29 around the eyelid. Repeat this several times a day.
