Myokymia?: Random twitching of an eyelid or another small facial muscle, which happens in normal people, is called myokymia (an involuntary, spontaneous, quivering of a few muscle cell bundles within a muscle). Myokymia starts and stops spontaneously. It can last a few minutes to a few days. One should see a doctor if such symptoms persist, keep recurring, or are combined with any other symptoms.

Blepharospasm: This is a condition called blepharospasm, which is thought to be due to a misfiring of certain types of neurons/muscles which control eye blinking (creating the twitching). Since the cause can be multifactorial, understanding a history and doing a physical exam is important to best address therapeutic options. Please see your doctor for further evaluation if it becomes bothersome.
