In short
Conjunctivitis, the medical name for pink eye, is an inflammation of the outer layer of the eye and the inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness, and is caused by bacterial or viral infections, allergies, irritating substances, or contact lens products, eye drops, or eye ointments. While pink eye usually does not affect vision and infectious cases spread easily between people, the infection clears in most cases without medical care, though bacterial pink eye requires treatment with antibiotic eye drops or ointment.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
