          There you are, minding your own business, when your eye starts to spasm 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
superstitions 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 twitching eye is
totally fine, although in some exceptional cases it may underlie a neurological
          Eye spasm is characterized by the spontaneous contractions of muscle
without muscular atrophy 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 eyelids).
          Eye spams are typically unilateral, occurring in one of the lower eyelids.
Sometimes, both eyelids may be involved but the fascicular contractions of each
eyelid is independent of each other. The transient and intermittent twitching is
semi-rhythmic at a rate of 3-8 Hz.
          In the majority of cases, eyelid spasms are no cause for concern. These are
usually self-limiting and benign, so medical intervention is typically
unnecessary. Very rarely, eyelid myokymia may occur as a precursor of hemifacial
spasm, blepharospasm, Meige syndrome, 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
hormones (cortisol) which triggers a “fight or flight” response. One immediate
consequence is muscle arousal, which may affect eyelid muscles as well. This may
be a good time to see your friends, unwind, or meditate in order to reduce the
stress that might be causing the twitching eye.
          Fatigue 疲劳
          Not getting enough sleep or working too much overtime may cause your eye to
complain. Scientists aren’t sure why, but they’ve found that getting more rest
will make the symptoms subside.
          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 chronic 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 twitch 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
stimulant 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 magnesium 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 deficient, you should focus on eating
more foods like almonds, oatmeal, or spinach. 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 hygiene
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 residue around the
eyelid. Repeat this several times a day.
