I've gotten extremely bad migranes for the past few years which cause intense pressure behind my right eye, and recently got glasses about 2 months ago, I'm getting an MRI in the next couple months, but the last 2ish weeks, I've noticed that my eyes have issues focusing when I read. I'll be reading something like instructions on a frozen dinner box or a menu or a news article, and my eyes will start to get shifty and blur and wont focus on what I'm trying to read.

Should I call my optometrist about this? Has anyone had this issue before?
