The Orbicularis Occuli Muscle controls the movement of your eyelids. It is located in the face and it closes the eyelids. It is the only muscle capable of this.
If the orbicularis occuli muscle loses it's function, then there would be no way
whatsoever to close the eye. In extreme cases, if the muscle does not work, necessitating eye drops at the minimum is used for the removal of the eye in extreme cases.
The palpebral (eyelids) portion acts involuntary in sleep or blinking. It closes the eyelids gently. The orbital (sockets) portion therefore develops conscious control. When the whole of the muscle is in action, the skin of the temple, cheek and forehead is brought toward the medial angle of the orbit and the eyelids are firmly closed. That occurs in photophobia (cannot withstand light/fear of light). Therefore, the skin that is drawn upon is thrown into folds.
Every time the eyelids close because of the orbicularis muscle, the medial palpebral ligament is tightened. Therefore, the wall of the lacrimal sac is drawn lateralward and forward, therefore, a vacuum is made in it and the tears are sucked along the lacrimal canals. The lacrimal draws the eyelids and ends of the lacrimal canals medialward. And that compresses them against the globe of the eye's surface. That is it's favourite position to produce tears.

∙ 6y agoThe orbicularis oculi muscle is the muscle that closes the eyelids. The palpebral portion of the muscle is involved in the blink reflex. The levator palpebrae superioris muscle retracts the eyelid to "open" the eye. This can be either voluntarily or involuntarily.

Can the Ciliary Muscle be under person's conscious control?
The straight answer is YES. You can try it yourself by closing one eye and making the computer screen blurry (thats your ciliary muscle working). However the muscle's primary control is involuntary (you may find yourself fighting it as you try to make the screen blurry). There is debate about the topic because it is a smooth muscle and it is innervated by autonomic nerves, both of which are typically exclusively involuntary. Also be careful: on exams answer NO, since typical questions will be asking for the primary function.
