Blurry Vision with POTS Flare: Need Advice

Blurred vision and tunnel vision are POTS symptoms. I always get them during presyncope, but sometimes if I'm having a large flare I will experience them more consistently thru the day, not just when I'm about to faint.

I swear my vision gets worse when my POTS is flaring up! Don’t know what the reason behind that is though.

I get blurry vision when my blood pressure drops when I’m standing too long or the heat is too much
