The three main types of conjunctivitis are infectious, allergic and chemical. The infectious type, commonly called “pink eye” is caused by a contagious virus or bacteria. Your body’s allergies to pollen, cosmetics, animals or fabrics often bring on allergic conjunctivitis. And, irritants like air pollution, noxious fumes and chlorine in swimming pools may produce the chemical form.
A good way to treat allergic conjunctivitis is to avoid the cause. If that is not possible, prescription eye drops may relieve discomfort. Bacterial conjunctivitis can be treated with antibiotic eye drops. Other forms, caused by viruses, cannot be treated with antibiotics. They must be fought off by your body’s immune system, though a short course of topical steroids is necessary in certain cases.
