Have you tried a neurological opthamalogist?

That made a huge difference for me. They were able to discern that my issues with close up vision were directly related to the concussion, and not aging. I now having "reading glasses" and also a pair that block out fluorescent lighting, (light sensitivity is a huge issue for me).

He also referred me for vision therapy, but I am still trying to get my insurance company to cover it.

I'm hoping to return to grad classes next spring... but I'm worried I'll be joining and ending up having to drop them.... I hate this and am so sorry you are having to go through it too.
