Blepharospasm is caused by abnormal brain function in the part of your brain that controls muscles. Symptoms can be triggered by something as minor as stress and being overly tired. Or it could be triggered by a neurological condition. Such conditions would include Touretteâs syndrome or Parkinsonâs disease.
Stress and fatigue definitely contribute, but the condition itself usually does not have any consequences for the normal function of the eye. Another type of eye twitch, called blepharospasm, may occur in a more persistent fashion (lasting weeks or months). In this condition, both eyes are usually involved, and the repeated involuntary blinking may be very annoying. The cause of this condition is unknown, and a complete eye examination is required to determine possible triggering events, such as dry eye, refractive errors, light sensitivity, and so on.
