“PINK EYE” also called conjunctivitis, may be an infection or an allergic reaction to dust, pollen, and other materials. The germs that cause conjunctivitis may be present in nasal secretions, as well as in the discharge from the eyes. Persons can become infected when their hands become contaminated with these materials and they rub their eyes. Eyes can also become infected when a person uses contaminated towels or eye makeup.
Bacterial and viral infections usually produce a white or yellowish pus that may cause the eyelids to stick shut in the morning. The discharge in allergic conjunctivitis is often clear and watery. All types involve redness and burning or itching eyes. Red and sore eyes may be part of viral respiratory infections, including measles.
As long as there is purulent (pus) eye drainage.
A visit to a physician is recommended when pus is present to determine whether antibiotic treatment is necessary.
