Good for you for getting his eyes checked! As I posted in another thread, this is one of my major "soap box" issues. My DD7 has worn glasses since 8 months old due to strabismus (the constant kind). We work with a terrific pediatric specialist who has done wonders with her through glasses (even bifocals!) and patching. For my DD, wearing her glasses makes a huge difference in her ability to focus and understand her school assignments. She never wants to take them off. You might find that the vision therapy has a really positive impact on your son. I sure hope so!
