Eye twitching is usually caused by fatigue, stress, too much smoking, alcohol, caffeine, and a few other factors. But even doctors do not know exactly what causes the eyes to twitch.
Certain types of allergies, irritation, and dry eyes can cause blinking. In some cases, eye twitching can be a symptom of blepharospasm (also called abnormal blinking or eyelid spasm) or a more serious, more severe neurological disorder called amyotrophic lateral sclerosis (ALS) or Lou Gehrig’s disease.
Statistics show that there are just over 2,000 cases in the United States each year, and blepharospasm in middle and late adulthood is more common in women than men. You should know that this condition is not serious if caught early. You become more sensitive to light, have blurred vision, and as the condition progresses, your entire face begins to twitch.
If the convulsions last for a few minutes, there is no need to worry, but if they last for more than an hour, you should see a doctor.
