Eye “Phenomenon”

[BPool18]

water has been near perfect for some time (thanks to the help from this site)

Though, recently had added some MA to Lower PH back to 7.5-7.6 range.

Today, while swimming, I opened my eyes underwater and it was crazy - almost like I had goggles on. Not just the clarity of the water, but no stinging or anything of that sort. Maybe a literally perfect water balance?

anyways, thought I’d share as this was a new one...

Human tears have a mean PH of around 7.0, anything much lower or higher will start to cause discomfort for your eyes.

Also don't forget that the PH scale is logarithmic and not linear.

Tears have pH of 7.4. You were very close to that.

Tears have pH of 7.4. You were very close to that.

The PH actually varies a reasonable amount depending on the actual person.

Here are some results which actually found that they varied between 6.5 & 7.6
