I'm glad you've seen an optometrist, because vision issues are one of those things that can hold kids back who'd otherwise accel.

However, if nothing changes quickly with attention to the vision issues, I would consider additional evaluation to make sure nothing else is being missed, and even more so when ADHD gets mentioned. There are other problems that can cause ADHD-like behavior -- the vision issue maybe, stealth dyslexia, or other processing difficulties or learning difficulties.
