Blepharoptosis or ptosis (pronounced TOE-sis) is defined as drooping of the upper eyelid. Ptosis can be bilateral or unilateral and can be difficult to identify unless a proper exam is performed.
Random twitching of an eyelid, 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. In the eyelids, it can last a few minutes to a few days. It can be caused by stress, dry eyes, lack of sleep.
