Conjunctivitis is a group of diseases that results in inflammation of the mucus membrane that covers the white of the eye and the inner lining of the eyelids.

At its onset, conjunctivitis is usually painless and does not adversely affect vision. It is usually caused by a viral infection, but can also result from bacterial infection, allergies, environmental irritants, eye drops and other eye products. Some forms are highly contagious and can spread from one person to another. If left untreated, some forms of conjunctivitis can cause corneal inflammation and result in loss of vision. The infection will clear in most cases without requiring medical care. But some forms of conjunctivitis need treatment. Delays in treatment may allow the infection to worsen, and cause corneal inflammation and a loss of vision.
