Pink Eye (Conjunctivitis): Types, Symptoms & When It’s Contagious

Pink eye — also known as conjunctivitis — is a common condition that causes redness, irritation, and discharge in the eyes. While it’s often mild, one of the biggest concerns people have is: “Is pink eye contagious?”

The answer depends on the type. Understanding the differences can help you protect others and get the right care quickly.

👁️ What Is Pink Eye?

Pink eye occurs when the conjunctiva — the thin, clear tissue covering the white part of the eye — becomes inflamed. This can be caused by infections, allergies, or irritants.
