Pink Eye (Conjunctivitis)

Pink eye or conjunctivitis is a common, mild infection of the eye. It can be caused by bacteria or viruses. Allergies and other irritants in the environment can also cause pink eye.

When to Seek Medical Care

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 follow-up. You should see a healthcare provider if you have pink eye along with any of the following:

• Moderate to severe pain in the eyes
• Vision problems, such as blurred vision or sight sensitivity
• Intense redness
• Symptoms persist or become worse
• A weakened immune system, for example from HIV or cancer treatment
• Pre-existing eye conditions that may put you at risk for complications or severe infection

Prevention

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.

Proper hand washing is highly recommended to prevent the transmission of pink eye and other infections. If you come into contact with any material that has been in contact with an infected person's eye, wash your hands immediately and thoroughly. Other ways to prevent pink eye from spreading include:

• Avoid touching an infected person's eye.
• Avoid touching tissues or gauze that have been in contact with the person's eye.
• Do not share or use washcloths, towels, pillowcases, eye makeup, or eye drops that have been in contact with the infected person.

Avoid Reinfection

• Clean eyeglasses.
• Replace contact lens solution used while infected.
• Throw away disposable lenses used while infected and clean extended-wear lenses as directed
