If you're still around... I figured out a way to get the ring around your pupils to disappear. I can't find your iris pics and don't remember what color your ring was... mine was white-ish... but anyway, ginger tea... one cup and my rings are gone. Its been a week and a half so far. I'm making myself another cup of tea now, so that reminded me.
I was told mine were low stomach acid so I'm assuming yours might be the same because it was the same area.
If you have a minute, I'm interested in finding out if your eyes changed at all after going paleo or got worse.
I cut out dairy and mine cleared up.
