“Will pink eye clear on its own?”

It is possible that a conjunctivitis "MAY" clear up on its own. BUT, there are several common types of conjunctivitis. And if you do have "red eyes" is it from a conjunctivitis or from something else affecting the eyes? As an example, a scratched cornea can cause red eyes. And there are internal eye problems that can cause red eyes. And depending upon which problem you may have, that will determine if drops are required or if it may clear up on its own. Bacterial conjunctivitis requires an antibiotic or an antibiotic-steroid drop. If you are sick with a virus, this viral conjunctivitis may require artificial tears, over-the-counter, and the use of cold compresses. An allergic conjunctivitis will require determining what you are allergic to (pollen, dander, dogs, cats, etc.), and the use of antihistamine drops or vasoconstrictor drops will help in this treatment. I would strongly suggest, to be on the safe side, to make an appointment with your family doctor, an eye doctor, or go to an emergency center. Good luck and best wishes.

usually not

If it’s viral then yes. But a lot of times we prescribe anti-inflammatory and symptomatic treatment.
