I don't believe the superstitions. There are so many superstitions in the world. Though they are interesting, they can't make sense. The same symptom can be explained in different ways and sometimes the answers go against each other. There are reasons which can explain this symptom scientifically. the reasons such as allergens, pollution, vision problems, lack of sleep, extreme stress and fatigue, magnesium or vitamin deficiency, inflammation of the cornea or eyelids, large consumption of alcohol and caffeine, neurological disorders like basal ganglia. You can find the causes and then find a way to stop eye twitching.
