Eye inflammation (conjunctivitis, pink eye) is an inflammation or infection of the membrane (conjunctiva) that lines the eyelid. It is often caused by bacteria or a virus finding its way into the eye. This results in infection, watery, weapy and irritated eyes and the production of yellow discharge.
Common causes of eye infections are due to allergies, bacteria, blocked tear ducts, dry eyes, respiratory infection or a recent cold. This condition is highly contagious and many children are often repeatedly infected. Another cause of non-infectious conjunctiva may be due to environmental pollutants such as smoke and perfumes which can cause irritation or redness to the eyes. This type of conjunctivitis usually clears up rapidly within a day or two and the discharge is more watery or mucous like rather than pus.
