After my TBI, I found that I had torn an eye muscle that the eye needs for positioning sight. I have now been fitted with a prism in my lenses that helps my eyes work together, a lifesaver! Before the change to my lenses, I was wearing an eye patch to occlude the vision in the affected eye. Also, you might have vertigo from a positional problem dealing with the calcium crystals inside the ear canal. Might be a help to see the ENT Doctor.
