Conjunctivitis is swelling (inflammation) or infection of the conjunctiva. This is the membrane that lines the eyelids and covers the white part of the eye.

CAUSES

The conjunctiva is exposed to bacteria and other irritants. Tears help protect the conjunctiva by washing away bacteria. Tears also contain proteins and antibodies that kill bacteria.

Conjunctivitis is most often caused by a virus. Viral conjunctivitis is referred to as "pink eye." Certain forms of pink eye can spread easily among children.

Other causes include:

Allergies (allergic conjunctivitis)
Bacteria
Certain diseases
Chemical exposure
Chlamydia
Fungi
Parasites (rarely)
Use of contact lenses (especially extended-wear lenses)

Newborns can be infected by bacteria in the birth canal. This condition is called ophthalmia neonatorum. It must be treated at once to preserve eyesight.
