Some of that sounds like my DS - his favorite place to sit is on me. He has a very hard time sitting in a chair (although better with feet supported properly). Not 'hyper' but needs to 'lean, flop, rest and lie prone' - exactly!
DS never complained about his eyes, and when I asked him if his eyes ever hurt or he saw double, he told me no. Yet he has a convergence insufficiency diagnosis. I think that he _can_ team his eyes together but he gets tired. So, tiredness is mostly what he complains of when reading.
DS also enjoys reading but gives up quickly. Although I doubt he'd get anywhere close to 190 wpm reading aloud.
