Despite being a long word, it actually means abnormal blinking. This is eyelid twitching that is a often a result of dry eyes but can also be found in Tourette’s syndrome, among other neurological conditions. It’s called Benign Essential Blepharospasm because it is not life-threatening in nature. While the essential is labeled because the cause is considered unknown, there are things you can do to reduce the likelihood of eye twitching.

Symptoms of Benign Essential Blepharospasm

  • Excessive blinking
  • Twitching that doesn’t go away
  • Sensitivity of light
  • Tired eyes
  • Heavy eyelids
  • Involuntary closure of eyes

Benign Essential Blepharospasm is an involuntary twitching that can revolve around one or both eyes and is often first noticed by the increased rate of blinking. This type of eye spasm can result in an involuntary shutting of your eyes.

A violent form of eye twitching, this condition can sometimes involve the entire side of your face. A Hemifacial spasm is a severe form of twitch that can affect your daily life, interfering with speaking or eating. It is caused by facial nerves that have become inflamed and this can be a symptom of a serious neurological problem.

Symptoms of Hemifacial Spasm

  • Involuntary closure of eyes
  • Blurry vision
  • Facial spasms along one side of the face
  • Sensitivity to light
  • Pain behind ears
  • Changes in hearing
  • Spasms from eye to chin

What causes eye twitching in Hemifacial Spasms might be harder to determine at first glance, but you should know that the condition can be relieved with either muscle relaxers or botulinum toxin injections to prevent the eye and facial muscles from spasming. There is also a neurosurgical procedure called microvascular decompression, which is used to relieve facial spasms. Though it has a good success rate, it is a neurosurgical operation and carries a higher chance of complications.

Caffeine & Alcohol

You’ve probably heard the term, “everything in moderation,” and that can be applied to pretty much anything we come across in our day to day lives. When it comes to stopping what causes eye twitching, you need to keep that running through your head. Caffeine and alcohol are both substances that our brains can get addicted to, they have a stimulant quality that our brains come to rely on. This chemical need for a substance is damaging to us on a whole, although some would consider alcohol to be far worse than over-consuming caffeine. However, the fact is that they both do damage to our bodies, just in different areas. When applied to our eyes these substances overwork our brains and actively cause dry eye.

Things to remember

  • Caffeine & alcohol are addicting
  • Over-consuming either has lasting effects
  • Causes dry eye
  • Causes minor eye twitching

In the U.S. the majority of Americans don’t just have coffee in the morning, but throughout the day as well. This over-consumption of stimulants has lasting effects on our brains as well as our eyes, and it can be what causes eye twitching because it leads to chronic dry eye. The daily recommended consumption of caffeine is 400 milligrams or less. For those who don’t know what that means, it equates to four cups of brewed coffee or two “energy shot” drinks.

Things to remember

  • Stimulant
  • Keep it to 400mg a day or less
  • Causes eye strain
  • Causes dry eyes
  • Causes minor eye twitching

Alcohol has lasting effects on our brain, liver, and eyes. Alcohol dries out the eyes, causing them to become red or bloodshot, and this can have the detrimental effect of tightening the muscles of the eye which can be what causes eye twitching for you. The daily recommended intake of alcohol is one drink for a woman and two drinks for men. This is what the CDC considers a moderate amount and the restriction is per day not per week. If you’re over-consuming alcohol on a regular basis, you may need to seek treatment as alcohol is an addictive substance.

Things to remember

  • Effects brain, liver, and eyes
  • Causes dry eye
  • Strains the eye muscles
  • Causes minor eye twitching
  • Addictive

Eye Strain

While alcohol and caffeine consumption are easily reduced and stress can be managed, eye strain is something that we’ve all faced. It’s a common occurrence in a digital age, but many don’t know what causes it or why. If you’re asking why is my eye twitching, then you should take a look around you and pay attention to what devices you might be relying too heavily upon.

Things to remember

  • Eye strain is caused by digital devices
  • It dries out eyes
  • Causes minor eye twitching
  • Can have a detrimental effect to eyes

Digital devices that we use like smartphones, tablets, and computers all use a digital screen that emits a type of light called blue light. Blue light is emitted from these devices in order to make viewing our screens easier, but the same thing that makes these devices readily available is actually harmful. Blue light although a naturally occurring form of light that we would get from the sun, but with how often and how long we use these devices, it is too much for our eyes to handle. This overabundance of blue light strains out eyes and is oftentimes what causes eye twitching as it dries them out, forcing our muscles to tighten as we try to overcompensate in order to continue using our devices. Make sure to get a pair of blue light blocking glasses, like those from Eye Love, to decrease your blue light exposure.


Treatment for what causes eye twitching

what causes eye twitching

The option of reducing certain stressors is one of the best methods of reducing the likelihood of experiencing eye twitching, however, in the cases of Blepharospasm and Hemifacial Spasm, there are other methods of relieving eye twitching. Botulinum toxin and surgery are options that may be considered.

Botulinum toxin

what causes eye twitchingEveryone has heard of botox, but most of those who have don’t realize that it’s actually referred to as Botulinum toxin. Botulinum toxin is a form of bacteria and like other forms of bacteria in large quantities can be poisonous, but before you swear off the idea of using it you should know that only a lower, weaker form is used when it comes to treating eye twitching. There are a few things you need to know when considering Botulinum toxin injections to relieve what causes eye twitching in yourself.

Things to remember

  • A form of bacteria
  • Does contain some risk
  • Can be used multiple times
  • Lasts anywhere from 3 to 6 months
  • Relaxes muscles
  • Blocks nerve signals

Unlike surgery, Botulinum toxin injections can be done repeatedly and as needed, usually lasting anywhere from three to six months at a time. The injections relax the muscles in the eye and prevent certain nerve signals from misfiring. This prevents eye twitching as the nerves and muscles can’t contract. When considering Botulinum toxin injections as a solution to what causes eye twitching, you should be aware that although it is less invasive than surgery, the injections do still carry some risk. The injections themselves are done with a very thin needle, and small doses of the toxin are injected above and below the eyelid. Bruising is a typical side effect.

Possible side effects

  • Headaches
  • Eye redness
  • Teary or watering eyes
  • Bruising or redness to the skin.

A more serious side effect from using Botulinum toxin injections is Ptosis, which is the drooping of the eyelids. This can make it hard to see as the eyelid impedes your vision. However, this side effect should go away just like the beneficial qualities once the botulinum begins to wear off, and it’s a very rare side effect anyway.


what causes eye twitchingMore invasive than the Botulinum injection is the option of surgery to combat what causes eye twitching. The procedure itself is a surgery called a Myectomy, which removes a portion of the muscle in the eyelids. Removing sections of nerves that misfire is also a part of the procedure, and the removal of this type of tissue prevents further eye twitching. Eye twitching is brought on by the contractions of a muscle or the misfiring of nerves.

Possible side effects

  • Loss of sensation
  • Inability to completely close eyelid
  • Increased need for eye drops
  • Chronic eyelid swelling
  • Infection
  • Hematoma

The majority of these side effects relieve themselves after recovery, but there are some side effects like chronic eyelid swelling that could potentially become permanent, just like the loss of sensation in the surrounding tissues, most often in the brow. Surgery is commonly used as a secondary means to treat what causes eye twitching. but t is the go-to method for those who no longer or have never reacted to Botulinum injections.

When to see a doctor

what causes eye twitchingAlthough the majority of eye twitching falls under the category of a minor eye twitch, just because you know what causes eye twitching doesn’t mean that you should scoff at the idea that there not be something else wrong.

Negative symptoms of eye twitching

  • Upper eyelid drooping
  • Eyes completely close with an eye twitch
  • Prolonged twitching lasting more than a few weeks
  • Twitching spreading to other areas
  • Swelling and discharge of the eye

One of the biggest hazards of having prolonged eye twitching is the possibility of it being a symptom of a neurological issue. Changes in the eyelids are normally one of the biggest signs that something might be wrong. The loss of control over facial muscles is a common occurrence in signs of a stroke or other neurological disorder. You should seek out a medical professional when your symptoms of what causes eye twitching fall outside of what minor eye twitching symptoms entail. Remember that eye twitching is normal unless it doesn’t go away.
