A quick comment re vision exams. You need to see a developmental optometrist. Because of different issues, my DS (then 8) saw two optometrists and a pediatric ophthalmologist. None of them caught the significant issues that th dev opt found, which included double vision, convergence and divergence insufficiency and tracking, among others. If you can get a referral within your local community for a developmental optometrist who is great with gifted kids, that would be preferred.
