Eye twitching, medically known as myokymia, is usually harmless and most often caused by stress, fatigue, caffeine, or eye strain. In most cases, it resolves on its own with rest and lifestyle adjustments. However, if twitching persists for more than a few weeks, affects other facial muscles, or is accompanied by vision changes, it may signal an underlying condition that warrants medical attention.

Because eye twitching can stem from many different causes—ranging from minor to more serious—it's worth understanding what's driving your symptoms before deciding on next steps. Take a free, instant, online symptom check to get personalized insights and clear guidance on what to do next.
