Pink Eye: Usually Mild and Easy to Treat

"Pink, itchy eyes? Pink eye – or conjunctivitis – is common and spreads easily. It sometimes needs medical treatment, depending on the cause. Know the symptoms, when to seek treatment, and how to help prevent it.

Pink eye, also known as conjunctivitis, is one of the most common and treatable eye conditions in the world in both children and adults.
