Involuntary and repetitive eyelid spasms happen for a number of reasons, and they’re more professionally referred to as blepharospasms. Generally speaking, blepharospasms happen to almost everyone during their lifetime, and 95% of the time, it’s nothing to worry about. In rare cases, however, blepharospasms can be a sign of a grave brain or nerve disorder.

These twitches are mild and controllable most of the time, and in some rare situations, they can be so strong that they cause the sufferer to shut their eye, or they can be unfelt completely, meaning some people with blepharospasm have never actually experienced it. If this condition doesn’t disappear by itself in a month from the first occurrence, and facial twitches begin happening as well, see a psychiatrist or a physician immediately. A good strategy of being able to presume what may be behind the eye twitch is to know its top ten potential causes.

1. Excess Energy

Energy overflow inside the body can be due to a number of things, ranging from anything that may increase physical activity (such as stress) to a regular cup of coffee. This energy has to go somewhere, and the nerves carrying it become overloaded.
One of the most frequent places where this energy is discharged is the eyelids. For unknown reasons, eye twitches occur mostly in the left eye. This could be related to the brain hemisphere controlling it, which happens to be more sensitive to blepharospasm’s causes.
