The conjunctiva is a thin, transparent membrane that covers the front part of the eye and lines the inside of the eyelids. It helps protect the eye from dust, debris, and microorganisms while also keeping it moist by producing mucus and tears. This membrane plays a crucial role in maintaining overall eye health. When the conjunctiva becomes inflamed, a condition known as conjunctivitis occurs, which can cause redness, itching, and discharge. Treatment often involves antihistamines or antibiotics, depending on the cause of the inflammation.
