Here are some examples:
* Ocular: related to the eye
* Oculist: an eye doctor
* Occipital: relating to the back of the head, where the eyes are located
* Binoculars: instruments that use two lenses to magnify objects, like eyes
* Occlude: to block or close off, like closing an eye
It's important to note that while "oc" often means "eye," it can also have other meanings in some words. For example, in the word "ocean," "oc" doesn't refer to an eye.
