Conjunctivitis (Pink Eye)
Pink eye, also known as conjunctivitis, is one of the most common and treatable eye conditions in children and adults. It is an inflammation of the conjunctiva, the thin, clear tissue that lines the inside of the eyelid and the white part of the eyeball. This inflammation makes blood vessels more visible and gives the eye a pink or reddish color.
The symptoms of pink eye may vary depending on the cause but usually include:
- Redness or swelling of the white of the eye or inside the eyelids.
- Increased amount of tears.
- White, yellow or green eye discharge.
- Itchy, irritated, and/or burning eyes.
- Increased sensitivity to light.
- Gritty feeling in the eye.
- Crusting of the eyelids or lashes.
Most cases of pink eye are mild and get better on their own, even without treatment. However, there are times when it is important to see a healthcare provider for specific treatment and/or close follow-up. You should see a healthcare provider if you have pink eye along with any of the following:
- Moderate to severe pain in your eye(s).
- Sensitivity to light or blurred vision.
- Intense redness in the eye(s).
- A weakened immune system, for example from HIV or cancer treatment.
- Symptoms that get worse or don’t improve, including bacterial pink eye that does not improve after 24 hours of antibiotic use.
- Pre-existing eye conditions that may put you at risk for complications or severe infection.
Pink eye caused by a virus or bacteria is very contagious and spreads easily and quickly from person to person. Pink eye that is caused by allergens or irritants is not contagious, but it is possible to develop a secondary infection caused by a virus or bacteria that is contagious. You can reduce the risk of getting or spreading pink eye by following some simple self-care steps:
- Wash your hands.
- Avoid touching or rubbing your eyes.
- Avoid sharing eye and face makeup, makeup brushes, contact lenses and containers, and eyeglasses.
