Conjunctivitis

Conjunctivitis is an inflammation of the conjunctiva, which is a transparent membrane that lines the inner eyelid and covers the white part of your eyes.

Conjunctivitis happens when the white part of your eye and the inside of your eyelids are irritated by an infection or by allergies. Eyes become red and swollen and may have a sticky discharge.

Conjunctivitis Types

Bacterial conjunctivitis. A red eye with a sticky yellow/green discharge. Eyelids may be stuck together upon waking. Can affect one or both eyes.
Viral conjunctivitis. The type of conjunctivitis most commonly associated with the term “pink eye”. Appearance: red, itchy, watery eye. Can affect one or both eyes. Highly contagious.
Allergic conjunctivitis. Very similar in appearance to viral conjunctivitis, but accompanied by nasal congestion, sneezing, eyelid swelling and sensitivity to light. Both eyes are affected. Not contagious.
