I’ve noticed that my eyesight has worsened significantly over the last six months or so. I thought I just needed a new prescription, but that didn’t help. I’ve just done some research, and it turns out that visual problems are common with ME/CFS, which surprised me, because I’ve rarely seen it mentioned. Tunnel vision, poor peripheral vision, and occasionally I see double for a while. It appears to be related to orthostatic hypotension, which I have, and the resulting impeding of blood/oxygen to the brain. I’m wondering, Has anyone else experienced this? If you took/take a drug for hypotension, did your vision improve/go back to normal?
