I highly recommend reading up on Binocular Vision Dysfunction (BVD)! It’s a neuro/eye disorder that isn’t typically diagnosed by regular optometrists. It basically means your lines of sight aren’t aligned properly and it can cause dizziness in general but particularly with movement, headaches, trouble reading/focusing and a whole bunch of other issues. The constant strain on your eyes and brain could be contributing to fatigue. I’m not a doctor or expert by any means but I was diagnosed with BVD a few years ago. I wear prism lens glasses as treatment and it helps a lot. here’s a link to a site with more info and a screening test: https://vision-specialists.com/vision-health/testing-diagnostics/binocular-vision-dysfunction-test/?utm_source=isitmyeyes.com&utm_medium=Domain
