Eye twitching is commonly caused by fatigue, stress, caffeine consumption, and excessive alcohol intake. Other factors include eye strain, dry eyes, environmental irritants such as bright lights or wind, and allergies. Eye twitches can also result from irritation of the eye surface or membranes lining the eyelids. In rare cases, persistent or severe eye twitching might be linked to neurological or movement disorders like blepharospasm, Parkinson's disease, multiple sclerosis, or Bell's palsy. Most eye twitches are benign and temporary, often resolving on their own after addressing triggers like stress and sleep hygiene.
