The eyes can contract infections from bacteria, fungi or viruses. Eye infections can occur in different parts of the eye, can affect just one eye or both eyes.   Besides infection, other kinds of inflammation may cause similar pathological changes in eyes. One common eye infection or inflammation that we'll take a look at is called conjunctivitis.

What is conjunctivitis?
Conjunctivitis is an inflammation or infection of the conjunctiva, the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye. Conjunctivitis, also known as "pink eye," is a common eye disease and may affect one or, more frequently, both eyes. While conjunctivitis is usually a minor eye infection, sometimes it can develop into a more serious problem.
