Conjunctivitis (Pink Eye)

Also known as: Conjunctivitis (Viral, Bacterial, and Allergic)

Conjunctivitis is inflammation of the conjunctiva, the thin, transparent membrane that covers the white part of the eye and lines the inner eyelids. It can be caused by viruses, bacteria, or allergies, and is one of the most common eye conditions. While often uncomfortable and highly contagious in its viral and bacterial forms, conjunctivitis rarely affects vision and usually resolves on its own or with simple treatment.

Common Symptoms

People with Conjunctivitis (Pink Eye) often experience the following symptoms.

Redness in one or both eyes

Itchiness or gritty feeling in the eye

Discharge that forms a crust during the night

Excessive tearing

Risk Factors

Certain factors may increase your likelihood of developing Conjunctivitis (Pink Eye).

Close contact with an infected person

Allergies to pollen, dust, or pet dander

Use of contact lenses, especially extended-wear types

When to See a Doctor

See a doctor if you experience significant eye pain (not just irritation), sensitivity to light, blurred vision that does not clear with blinking, or intense redness in one eye. Seek prompt care if you are a contact lens wearer with eye redness, if symptoms worsen after a few days, or if a newborn develops eye redness or discharge. These situations may require prescription treatment.
