It is possible to prevent infectious conjunctivitis. Wash your hands frequently and avoid touching your eyes. At home, never share towels, washcloths or facial cosmetics with others, especially eye makeup.
To prevent conjunctivitis in newborn babies, all pregnant women should be tested and, if necessary, treated for gonorrhea and chlamydia infections. As another preventive measure, newborns routinely are treated at birth with antibiotic eye drops.
