What was the treatment for his lazy eye? Lazy eye can be a symptom of severe farsightedness. We went through three eye doctors before we learned DS is severely farsighted. The last one is very knowledgeable about kid's eye issues.
BTW, we were amazed to learn how bad the farsightedness was, given that he read constanstly pretty early, was great at complex puzzles, etc.
