I took both my kids to a regular optometrist and I asked him about Vision Therapy, he told me it was basically a scam (and he said he has a child that was gifted). I then spoke to someone who specializes in giftedness about my son's underachievement and anxiety and he said that he would recommend having someone check my son's eyes for Convergence Insufficiency (and basically whether or not he would need vision therapy). I told him what the eye doctor had said and he said that vision therapy does work.

So now I'm confused as both people were very convincing and I felt they were giving me their honest opinion and looking out for my best interest. For those who have tried it, did it work?
