Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the conjunctiva, the thin and transparent layer of tissue that covers the front surface of the eye and lines the inside of the eyelids. Various factors, including viruses, bacteria, allergies, or irritants, can cause it. Conjunctivitis typically presents with symptoms such as redness, itching, watering, and discharge from the eye. Depending on the cause, treatment options may include prescription eye drops or ointments, antihistamines for allergic conjunctivitis, or simply using warm compresses and practicing good hygiene to alleviate discomfort and promote healing. It is essential to seek professional medical advice for an accurate diagnosis and appropriate management of conjunctivitis.
