The orbicularis oculi muscle is primarily responsible for functions related to the movement of the eye and eyelids. Its main actions include closing the eyelids, compressing the lacrimal sac to assist in tear drainage, and facilitating blinking to protect the eye and spread tear film for lubrication.

Raising the eyebrows, however, is not a function of the orbicularis oculi. This particular movement is accomplished by a different muscle, specifically the frontalis muscle, which is located in the forehead. Therefore, recognizing the orbicularis oculi's roles highlights that it does not involve raising the eyebrows, thus making the selection of that option the correct choice for what does not pertain to the functions of this muscle.
