Pinkeye

What Is Pinkeye?

Pinkeye -- also called conjunctivitis -- is redness and inflammation of the clear membranes covering the whites of the eyes and the membranes on the inner part of the eyelids. Pinkeye is most often caused by a virus or by a bacterial infection, although allergies, chemical agents, and underlying diseases can also play a role.

Is Pinkeye Contagious?

Viral and bacterial pinkeye are extremely contagious. It's easily spread through poor hand washing or by sharing an object (like a towel) with someone who has it. It can also spread through coughing and sneezing. Kids diagnosed with infectious pinkeye should stay out of school or day care for a short period of time. Allergic pinkeye (caused by seasonal pollens, animal dander, cosmetics, and perfumes) and chemical pinkeye (from chemicals or liquids, including bleach and furniture polish) are not contagious.

Symptom: Eye Redness

Redness of the eye is the typical, telltale symptom of pinkeye. Pinkeye is a common condition that is rarely serious and unlikely to cause long-term eye or vision damage if promptly detected and treated.

Symptom: Swollen, Red Eyelids

The symptoms of infectious pinkeye typically begin in one eye and involve the other eye within a few days. Symptoms of allergic pinkeye usually involve both eyes. Swelling of the eyelids is more common with bacterial and allergic pinkeye.

Symptom: Lots of Tearing

Viral and allergic pinkeye are known for causing more tear production than usual.

Symptom: Itchy or Burning Eyes

You would know it if you felt it -- that overwhelming itchy, burning feeling in the eyes, which is typical of pinkeye.
