Pink eye, which is also known as conjunctivitis, is an inflammation of the conjunctiva – the thin, clear tissue that covers the white of the eyes and the inside of the eyelids. It is a common eye infection that can affect people of all ages, although it is more common in children. Pink eye can be caused by bacteria, viruses, or allergies, and it is highly contagious.

To treat pink eye illness, it is important to identify what is causing the infection. Bacterial conjunctivitis can be treated with antibiotics, such as drops, ointments, or pills. Viral conjunctivitis can't be treated with antibiotics, but the symptoms can be managed with cool compresses and artificial tears. Allergic conjunctivitis can be treated with antihistamines, decongestants, or anti-inflammatory drops.
