I'm not sold. We had a pool when I was growing up and since I was the youngest child, there was a several year stretch in high school where I was taking care of the chemicals in the pool and really the only person ever swimming in it.

If the pool was looking a little green, I dumped some chlorine in and guess what, the increased chlorine created increased irritation to my eyes. And no, I wasn't the kind to pee in my own pool - not that the amount of pee I could generate would cause the requisite chlorine-pee interaction that makes the pool such an irritant.
