Elaine, I think I missed reading the last page of this thread. If you're still here, you have great wide teeth on top! I wonder if your problem was entirely your lower set of teeth? Braces can't make a wide palate like it appears you have.
I think myopia is diet-related. I've stopped it in my children, and am still amazed that it worked. Other problems, like amblyopia, etc., I think are likely related more to parental diet, but that's just a guess; I haven't researched it.
