Look into Irlens Syndrome. It is a light sensitivity that doesn't allow for certain Rays of light to be processed by the brain, thus causing the brain to overstimulate and processing of any reading doesn't occur. It's like your watching tv and your seeing it, but you don't know what's actually happening because your brain isn't putting the pieces together.

I've gotten the lenses and they have changed my life. No more headaches, nausea, head numbness, disorientation, and I can turn my head without feeling like i just got shaken into a different stratosphere.

I think it could be of great benefit to you.
