If your lower eyelid feels like it’s moving, but you can’t see it, it’s usually due to orbicularis oculi spasm. The orbicularis oculi muscle is a part of the expression muscle, arranged in a ring, located inside the subcutaneous tissue of the upper eyelid, and its main function is to close the eyelid when contracted. When the orbicularis oculi muscle spasms, it will contract periodically and rhythmically without the patient’s conscious control in response to abnormal impulses from the facial nerve that innervates the orbicularis oculi muscle, and the eyelid will feel like it’s throbbing, but the appearance is not necessarily able to see the abnormality. Treatment, pay attention to rest, do eye hot compresses, can be in the local ophthalmologist under the guidance of oral methylcobalamin tablets and other neurotrophic drugs for treatment. Lower eyelids feel moving, but can not see, timely to the consultation.
