Pink eye, also known as conjunctivitis, is an inflammation of the transparent membrane that lines the eyelid and eyeball called the conjunctiva. The symptoms of pink eye can vary depending on the cause of the irritation or infection. The most common symptoms include:

• Redness or pink color in the white of the eye(s)
• Swelling of the conjunctiva (the thin layer that lines the white part of the eye and the inside of the eyelid) and/or eyelids
• Increased tear production
• Feeling like a foreign body is in the eye(s) or an urge to rub the eye(s)
• Itching, irritation, and/or burning
• Discharge (pus or mucus)
• Crusting of eyelids or lashes, especially in the morning
• Contact lenses that feel uncomfortable and/or do not stay in place on the eye

Pink eye can be caused by a virus, bacteria, allergies, or irritants. Bacterial and viral conjunctivitis are easily spread from person to person, while allergic conjunctivitis is not contagious. The treatment of pink eye varies based on the cause and can include antibiotic and/or steroid drops or ointments, anti-viral eye drops or pills, allergy eye drops, or artificial tears. If you suspect you have pink eye, it is important to see a healthcare provider for a proper diagnosis and treatment.
