Twitching under the left eyelid may be caused by various factors. Eye strain, poor sleep, or high levels of mental stress can lead to eyelid muscle spasms, manifesting as eye twitching. Medical conditions such as bacterial conjunctivitis, keratitis, dry eye syndrome, and blepharitis may also stimulate the nerves in the eye area, triggering eyelid twitching. In addition, eye injuries or facial nerve spasms could also cause this symptom. For such cases, it is recommended to rest the eyes adequately, avoid prolonged eye use, and maintain healthy sleep habits. If symptoms persist or worsen, timely medical consultation is advised to identify the underlying cause and receive appropriate treatment.
