Conjunctivitis is a medical condition in which the conjunctivae appear
pink or red, and the eyes water and feel irritated. In some cases the eyes may
feel scratchy or itchy as well. Conjunctivitis can be caused by a bacterial,
chlamydial, or viral infection; by seasonal allergies; by a foreign object in the
eye; by a chemical irritant; or by such other medical conditions as dry eye.
There may be mild sensitivity to light, a condition known as photophobia.
