Answer by finette (157) Pink eye can be caused by fecal bacteria getting into the eye, but there are a lot of other possible causes as well. The most common cause of pink eye (also called conjunctivitis) is a viral infection, which can be spread from person to person just like a cold. Pink eye can also be caused by an allergic reaction.
What Causes Pink Eye? The primary types of conjunctivitis, based on cause, are: Viral conjunctivitis. Caused by a virus, like the common cold. This type of pink eye is very contagious, but usually will clear up on its own within several days without medical treatment. Bacterial conjunctivitis. Caused by bacteria, this type of conjunctivitis can cause serious damage to the eye if left untreated. Allergic conjunctivitis. Caused by eye irritants such as pollen, dust and animal dander among susceptible individuals. Allergic conjunctivitis may be seasonal (pollen) or flare up year-round (dust; pet dander).
