These include: Infectious ConjunctivitisThis type is caused by a bacterial or, more commonly, viral infection. It spreads rapidly from person to person. Viral conjunctivitis is most often caused by adenovirus, a virus associated with respiratory diseases and the common cold. It can be the result of exposure to the coughing or sneezing of someone with an upper-respiratory-tract infection, and it can develop as a virus spreads through a person’s body. In addition to other viral infections (from the common cold to measles), COVID-19 has also been associated with conjunctivitis in children — though the data is still preliminary, according to the Cleveland Clinic. Staphylococcal or streptococcal bacteria usually cause bacterial conjunctivitis. Infection can be spread through person-to-person contact, hand-to-eye contact, or eye contact with a contaminated object such as makeup or contact lenses. Allergic ConjunctivitisThis type tends to happen in people who normally get allergies and occurs when the eyes are exposed to a trigger or allergen that causes an allergic reaction. The most common form of allergic conjunctivitis is seasonal. It’s triggered by mold spores or pollen from flowering trees, grass, and weeds. The year-round form of allergic conjunctivitis is usually caused by allergens such as animal hair or dander, feathers, and dust mites, according to the CDC. Irritant or Chemical ConjunctivitisThis type of pink eye is brought on by environmental factors that irritate the eyes. These can include smoke, car exhaust, air pollution, soap, cleaning products, hair spray, makeup, and the chlorine found in swimming pool water, notes the Cleveland Clinic. Ophthalmia NeonatorumThis severe form of bacterial conjunctivitis occurs in newborn babies. It’s caused by exposure to gonorrhea and chlamydia in the birth canal.
