What causes eye twitching?

Eye twitching, also known as eyelid spasms or twitching eyelids, may be caused by various factors. 1. Eye strain is a common cause; for example, prolonged screen time on computers or smartphones can easily lead to eye fatigue and result in spasms of the eyelid muscles. 2. Eye conditions such as conjunctivitis or keratitis may stimulate nerve endings and trigger eye twitching. 3. Psychological factors, including excessive stress or mental tension, may lead to weakness in the eyelid muscles and consequently cause twitching. 4. Hemifacial spasm can also manifest as eye twitching, which is usually associated with damage to cranial nerves or primary facial nerve paralysis. For eye twitching, it is recommended to adjust eye usage habits, maintain good psychological health, and seek medical attention for professional treatment when necessary.
