Some pathogenic microorganism including bacterium, virus, transmitting in two ways: infected eyes-water-healthy eyes and infected eyes-hands or objects-healthy eyes. Among the two ways, transmitting through water is more common and faster. If the water in swimming pool is polluted by pathogenic microorganism and sterilization is not strict, at the same time, the swimmers do not take necessary protective measures, they will get the disease in eyes one to several days after contacting the polluted water.
