Eyelid twitch also goes by its medical name of myokymia. This is an involuntary, repetitive spasm of the eyelid muscle. It can occur in the upper eyelid or in the lower one. In most cases, these twitches are harmful and pain-free.

However, the mild eyelids gently tug the eye and can turn out to irritate you. Most of these eyelid twitches resolve themselves without any need for treatment. However, questions of why it happens can be crucial. After all, it’s your eye that we are talking about here.

Before we proceed with exploring the possible causes behind the eye twitching, it is best to know what blepharospasm is. This is a different condition, which is characterized by strong spasms in the eyelids, which force both of your eyelids to close entirely.

Possible reasons behind eye twitching

Broadly, some of the possible cause of eye twitch according to the Mayo Clinic include:

  • Bright light
  • Alcohol intake
  • Physical exertion
  • Wind
  • Stress
  • Smoking
  • Irritation of the inner eyelid or eye surface
  • Excessive caffeine intake
  • Fatigue
  • Physical exertion

Some other reasons include poor nutrition, vision problem, dry eye, and allergies. Here is more on the chief reasons that can answer your worry of, ‘why my eye twitches’:

1. Fatigue

Cheating on getting proper sleep can induce an eye twitch. The odds are high if you fail to catch your zzz due to stress or such other related reason. Catching up with your sleep can help curtail the eye twitch.

2. Alcohol intake

If you notice that your eyes start twitching in the aftermath of having alcohol, then you’ll have to stop drinking better, liquor, or wine.

3. Eye strain

An overuse of tablets, computers, and smartphones can also plant the seeds of eye twitching. In fact, eye strain due to an overuse of digital gadgets. Follow the 20-20-20 rule when using digital devices to prevent eye strain.

In that, look away from your screen after every 20 minutes. Look away and allow your eyes to focus on a distant object. It should be at least 20 feet away. Try to do this for 20 seconds or longer. This helps lessen fatigue. If you use a lot of e-screen, you can ask your doctor for computer eyeglasses.

4. Dry eyes

Adults experience dry eyes, particularly, after 50 years. Dry eyes are also common among people who use electronic gadgets, wear contact lenses, consume alcohol or caffeine, take some medications such as antidepressants and antihistamines.

If your eyelid twitches and your eyes feel dry, check with an eye specialist for a dry eye evaluation. Restoring the moisture to your eyes can help to treat myokymia.

5. Allergies

Some people with eye allergies can have itching, watery eyes, and swelling. When your eyes rub, it releases histamine into the eyelid tissues, which chips in eye twitching. An eye doctor can recommend antihistamine eye tablets or drops to assist some eyelid twitches. Antihistamines can cause dry eyes though so prevent overuse of these.

6. Stress

Stress is another typical cause behind eye twitching. Beat stress with the help of practicing breathing exercises, yoga or whatever works for you.

7. Poor nutrition

Poor nutrition contributing to a lack of certain nutrients such as magnesium can trigger eye spasms. Although research in this regard is not solid, this possible reason behind eye twitches cannot be ruled out. If you are concerned about your diet, try to switch to eating a healthy, well-balanced diet so that your body gets all the needed nutrients.
