To distinguish from eyelid tremor. Eyelid tremor is mainly composed of the orbicularis muscle and the eyelid muscles. Eyes jump in medicine called "eye tremors." Under the support of the optic nerve and facial nerve, the eyelids complete the function of blinking and closing the eyes, which protects the eyeball, cleans and lubricates the conjunctiva. Eyes are not the skin is jumping, but the orbicularis muscles and the eyelids are under the control of the nerves, which contract and impede the surface skin.
