Culprit in burning eyes issues?

[joshs2000ss]

My son is 5 and doesn't like to swim in goggles. After spending quite a bit of time in the pool he says his eyes burn and they look red. All of my numbers seem to be good so I'm not sure what the issue is. My latest test, right before they swam last was:

PH - 7.3
FC - 5.5
CC - 0
CYA - 65
TA - didn't test that time, never had any issues, usually right at 90
CH - agents are bad and haven't tested, but again, no issues in the past
Salt - 3000

Which, of the chemicals that are in the pool, are most likely to cause issues with the eyes? Is this just normal with long sessions of being in the pool with no goggles and going underwater with your eyes open?

I believe a pH under 7.2 can cause your eyes to burn. Since the pH test is a bit subjective, an easy test might be to bump your pH up to 7.5 to see if it helps.

The pH had been at 7.8 and I added enough Muratic Acid (the night before) to bump it down. I'll check again and see where it is. It tends to climb with the SWG, so I don't think it has fallen below 7.2.

Well, that basically covers the issues I know of. (Low pH which you addressed, high CC to which you reported zero, and no salt to which you reported 3000)

Is this a new thing? Has anything changed? Is his nose burning too or just his eyes? I suppose it could just be a fluke experience and only cause was that he just overdid it. Hopefully someone with more experience in this area will follow-up.

Low PH (below 7.2) and CC (above 0.5) are the two most common causes for burning eyes.

Ok. I was under the impression that 7.2 - 7.8 was ok. I intentionally dosed for 7.3 so as to not overshoot 7.2 I'll balance for 7.5 or a little above in the future and see if that makes a difference.

Sorry, typo. below 7.2! Anything from 7.2 on up above 8 is fine as far as your eyes go.
