Infections and Chem. Newborns can get conjuctivitis from chemicals (prophylaxis for infections at birth), bacteria (gonorrhea, chlamydia), or viruses (herpes). Any large amount of discharge and red/watery eyes should prompt an exam by a physician.
Red eye. Usually bacteria, but it could be a virus or chemical irritant. Call your local pediatric ophthalmologist for an appointment.
Viruses and bacteria. Cause the infections. Children do not have the best hygiene and will touch their eyes with unclean fingers. They can also get an eye infection that travels up to the eyes from an infection in the nose. Infants can have an eye infection from exposure at birth.
