Swimming is great exercise, but eyes are sensitive to aquatic contaminants. Eye infections and inflammations are widespread among swimmers. Treat any threat to vision with care.Exercise caution when swimming in public pools. Do not swim in a pool with leaf litter. Avoid swimming with large numbers of people. Stay out of swimming pools with small children. Wash before entering the water. Do not change diapers in swimming pools.Swimming pools contain many chemicals and potential contaminants. Chlorine and other chemicals are added to pool water to control bacteria, but these chemicals also can irritate the eyes. Chlorine kills germs--but not instantly. Remove all litter from the water. Maintain the filtration system. Maintain a healthy aquatic environment for all swimmers.Conjunctivitis, or pink eye, is the most common type of eye infection. Bacterial conjunctivitis can be treated with antibiotic drops or ointment. Use eye drops to relieve eye irritation from viral conjunctivitis. Do not rub your eyes. Use tissue to dry the eyes, and dispose of them properly after use.
