Anyone who has been in the pool or hot tub will tell you that at one time or another they've opened their eyes underwater. But this brings up a bigger question - is it safe to open your eyes underwater?
Many believe that he chlorine in the water causes eye redness, but the water's pH level is actually the cause! The pH level measures how acidic the water is, if the pH is above or below the correct range they your eyes get irritated.
According to studies, your eyes won't experience any long term harm due to pH levels if you open them underwater (Unless the water's pH or other chemicals extremely out of balance). Although, water with levels of infectious bacteria may be something to worry about. Exposure to infectious bacteria can lead to an eye infection. We recommend wearing Google if you are swimming in a public pool, unknown pool or other unknown water.
