Pinkeye, also known as conjunctivitis, is the irritation and inflammation of the conjunctiva, or outermost layer of the eye, and can cause your eyes to become painful, red and watery. Although viruses cause most cases of pinkeye, it can also be caused by bacteria, allergens or chemicals. The most common bacterial causes of pinkeye are Staphylococcal (Staph) and Streptococcal (Strep) species, though this accounts for only 5 percent of cases. Allergies to indoor and outdoor particles like pollen, pet dander or household molds can cause eye irritation as well.
