Sounds like lazy eye. I had to wear a patch to help my lazy eye strengthen. Still when I get tired, my eye like to wander. But not so much it's noticeable. Just where I notice it. I never had surgery so without glasses I can not see out of my left eye. You don't need an MRI or EEG for it. Just go to the eye doctor and they can tell you it's lazy eye.
