Of course a poorly treated pool will irritate your eyes, pH is an issue.
how are you not gonna get whatever sweat on you in the pool
Of course you can't keep all bodily fluids out of a pool, that's not the point. You will eventually have to change the water even if nobody pees in it. The point is to avoid needlessly dumping waste into the pool, because that means that they'll either have to change the water out sooner, or the water will be more contaminated with chloramines (and thus more irritating) until it's changed out at the next regular time.
Also, I'm not sure I agree that there is more sweat than pee in most pools. If you're doing heavy laps for an hour you'll sweat about a liter. All it takes is for a kid to relieve their bladder once to dump that much in. But that's beside the point. If you can easily avoid further contaminating the pool by walking to the urinals, then do so.
Is your goalpost on wheels?
