An eye twitch is a condition whereby the movement of your eye muscle or eyelid cannot be restrained. This eye condition usually happens more in your upper eyelid and your lid moves every few seconds typically for 1 to 2 minutes.
There are 3 types of eye twitching. The first type is called a minor eye twitch. This condition is usually associated with banal matters such as fatigue, stress or caffeine. When the cornea (transparent layer at the front of the eye) or the conjunctiva (membranes that line your eyelids) get irritated, your eye might also twitch slightly.
Benign essential blepharospasm is the second type of eyelid twitching that generally surfaces in mid to late adulthood and exacerbates as time goes on. This condition begins with eye irritation or non-stop blinking. As benign essential blepharospasm worsens, you may suffer from blurry vision, become more sensitive to light as well as get facial spasms. Sometimes, these spasms might become so intense that your eyelids have to remain shut for hours at a time. While benign essential blepharospasm is normally not a grave condition, more serious episodes might impact your everyday life.
The third type of eye twitching that is hemifacial spasm is very uncommon. Hemifacial spasm commonly impacts only one side of your face and entails your eyelid muscles and the muscles surrounding your mouth. This condition is generally due to an artery pressing on a facial nerve.
Your eye might twitch because of an unusual signal in your brain or the muscles of your face. Banal activities and things that can cause eye twitching to entail:
While fairly rare, certain disorders in the nervous system and the brain can lead to eye twitching. Some of these disorders are:
Your eye spasms might not simply last you for a couple of minutes. In fact, you might suffer from spasms all day, and for days, weeks or even months. These spasms, when prolonged and uncomfortable, can reduce the quality of your life and prevent you from concentrating on your everyday duties. If you have persistent eye twitching, your vision might suffer and you might have to squint or wink consistently. Consult your doctor when:
If your doctor thinks you might be having a more underlying serious condition such as a brain or nerve problem, you would be examined for other symptoms or would be referred to a neurologist (nerve specialist).
Get lots of rest and reduce your tobacco, alcohol, and caffeine intake if you have a minor eye twitch. Use eye drops to address irritated or dry eyes.
Although there is not any cure for benign essential blepharospasm, you can mitigate your symptoms with medications prescribed by your doctor. If it is severe or disrupting your daily activities, your doctor may recommend surgery like myectomy to remove some of the muscles and nerves around your eyelid. Surgery can also permanently ease the pressure of the artery on your facial nerve that causes a hemifacial spasm. That being said, bear in mind that as with any operation, surgery for your eyelids can carry risks.
