Is the red eye's people get while swimming due to the ph or the alkalinity being off? Is it too high or too low? How does it effect the eyes if it is too high or too low?
It used to be said that it was chlorine that caused the red eye's but I read (maybe somewhere here) that that is not the case.

I'm sure someone here can supply me with the info on how to eliminate the red eye problem(besides Visine).

Thanks
