I totally relate about the not knowing when to get glasses with the changes in vision. A couple years ago I got a pair when things were bad, then had to go back and tell them I couldn’t see through the glasses a few weeks later. All my testing including eye pressure was different just a few weeks apart. I try to get examined when things are pretty good now, so I can use the glasses more of the time. Hope you are getting some progress with your other problems.
