What is eye gunk made up of?

* Mucus: Mucus is produced by glands in the eyelids and conjunctiva. It helps to keep the eye moist and lubricated, and it traps bacteria and other particles that could damage the eye.

* Oil: Oil is produced by glands in the eyelids. It helps to keep the eye moist and prevents tears from evaporating.

* Dead cells: The surface of the eye is constantly shedding dead cells. These cells are swept away by tears and eventually end up in the eye gunk.

* Bacteria: Bacteria are normally present on the surface of the eye, and they can sometimes be found in eye gunk. However, the presence of bacteria in eye gunk does not necessarily mean that there is an infection.

* Other particles: Dust, pollen, and other particles can also get into the eye and end up in the eye gunk.
