sorry for your troubles,

I had a concussion a year ago and am still dealing with effects.....fatigue, headaches, spaced out, slow mental processing, noise and light sensitive, ear ringing, cant exercise....its terrible and I just dont feel like myself anymore...

maybe because your injury occurred when you were younger you didnt notice some of the other effects....vision is obvious...some of the others are more subtle, but maybe vision is your only problem....if you are productive and can work and study I wouldnt worry....for more info just google TBI symptoms...gluck
