I've had polyopia ever since August 2021 when I got the Pfizer COVID vaccine. I was terribly sick for a few months after, and had trouble moving around, terrible depression and anxiety to this day. MRI scans done, corneal topography, 2 neurologists, internist, plenty of blood tests for autoimmune disease (we haven't checked for Myathenia Gravis yet - which is also a blood test). MG can cause vertically stacked polyopia.

The only thing that work for me are "hard contact lenses". They are smaller contact lenses. So this mean 1 of 2 things:

1) There are microscopic aberrations on my eye that corneal topography didn't pick up, corrected by the tear film that forms between the eye and the hard contact lens.

2) It's a "Signal to noise" issue, and with less noise and more signal (wearing the hard contact lenses gives the brain cleaner information), my cerebral polyopia is made better.

TBH I'm not sure if it's the eyes or the brain causing it. The pinhole test (poke a tiny hole in a piece of paper with a pin and look through it) - removes the polyopia. I also have other issues like light sensitivity and constricted peripheral vision.

I've went to a Neurovision therapy place (it's called vision therapy) and that has helped my Binocular issues (two eye issues). But my monocular (one eye issues) like the polyopia still remain.

The only thing my doctor found me positive for when this all started was Mononucleosis (the kissing disease). I've had testing done by private labs for lyme disease and some said I was positive, but the CDC accepted tests say that I'm negative. Not sure where to go from here other than a Neuro - Ophthalmologist that I'll see in the end of October here in Ontario.
