What Causes it?

Muscle movements in human beings are controlled by nerves that are located at the base of the brain. When these nerves begin to malfunction, one of the symptoms may be manifested in the twitching of the eyes. In most people, however, twitching eyelids (blepharospasm) has no known cause, and cannot be linked to any specific factors. Besides nerve abnormalities, other possible contributing factors include:

• Conditions of stress
  
• Irritation in the eye
• Tiredness or fatigue
  
• Lack of sleep
• Prolonged television viewing or staring at the computer monitor
• Excessive intake of coffee

While in many causes, eye twitching need not be taken as a cause for alarm, always consult a doctor to rule out the possibility of any deep rooted cause for your eye muscle spasms.
