The muscle jumping in the lower part of the eye can be considered to be related to physiological factors such as eye fatigue or sleep deprivation, and some pathological factors such as facial muscle spasm, ocular lesions, and neurological disorders can also cause muscle jumping in the eye. 1. Physiological factors: eye muscle throbbing belongs to blepharospasm. Generally, it can be caused by eye fatigue, overuse of eyes or insufficient sleep, which will lead to eye muscle spasm and more frequent throbbing. It is recommended to ensure sleep, rest on time, and do some eye relaxation exercises. 2. Pathological factors: Facial muscle spasm usually starts with a slight fluttering of the orbicularis oculi muscle, and gradually extends to the entire orbicularis oculi muscle and even the whole face. Inflammation of the eye, such as conjunctivitis, keratitis, inflammatory factors stimulate the muscles, can lead to muscle spasm. In addition, some neurological diseases such as facial nerve palsy, tumor compression of the nerve, can also cause eyelid spasm. When you find frequent fluttering of eyelids and facial muscles, go to the regular hospital for diagnosis and treatment.
