Lid Myokymia: Twitching of the lid is usually associated with fatigue or dry eyes, but any irritation of the trigeminal nerve (CN 5) could cause a reflex contraction of the orbicularis oculi muscle (CN 7 - facial nerve) , resulting in a fasciculation of the lid. In most cases this is benign, and relieved with rest and artificial tears. See an ophthalmologist for an eye examination if persists with new glasses.
