Conjunctivitis is an inflammation of the thin, transparent layer that lines the inner eyelid and covers the white part of the eye. The three main types of conjunctivitis are:
- Infectious, or “pink eye,” caused by a contagious virus or bacteria
- Allergic, the body’s reaction to pollen, cosmetics, animals or fabrics
- Chemical, a response to irritants like air pollution, noxious fumes and chlorine in swimming pools
Symptoms are red watery eyes, inflamed inner eyelids, blurred vision, a scratchy feeling in the eyes and, sometimes, a pus-like or watery discharge. See ECA eye care for diagnosis and treatment.
