Pink eye, also known as conjunctivitis, is a common eye infection that causes inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and lines the eyelid. Pink eye can have a variety of causes, including bacteria, viruses, allergies, and irritants. Symptoms of pink eye include redness, swelling, itching, tearing, and discharge.
While pink eye is usually not a serious condition, it can be uncomfortable and contagious. Treatment for pink eye typically involves antibiotics or antiviral medications, depending on the cause. In some cases, pink eye may also be treated with over-the-counter eye drops or artificial tears.
