The most common reasons for left eye twitching, like in the right eye, are usually benign and include factors such as fatigue, stress, anxiety, excessive caffeine or alcohol consumption, eye strain, and irritation of the eye surface or eyelids. Eye twitching, medically known as eyelid myokymia, is an involuntary spasm of the muscles around the eyelid. It often occurs in the upper eyelid but can affect both lids. Other less common causes include neurological conditions like benign essential blepharospasm, hemifacial spasm, or disorders affecting the brain and nervous system such as Parkinson's disease, multiple sclerosis, or Bell's palsy, although these usually come with additional symptoms. Typically, eye twitching is temporary and resolves on its own once triggers like stress or fatigue are reduced. However, if twitching persists for more than 2-3 weeks, causes eyelid closure making it difficult to open the eye, spreads to other parts of the face, or includes redness, swelling, or unusual eye discharge, it is advisable to seek medical advice. In summary, left eye twitching is most often due to benign causes such as tiredness, stress, caffeine, or eye strain, and is usually not a sign of serious illness.
