I don't have any advice but I just had to saw WOW and hooray that you've found another piece to the puzzle that is a 2e kiddo.

I also think I need to get DS tested - like you I have watched various optometrists wave pens in front of him for years (he's had glasses since age 4 as well). I assumed we were covered, guess I should do some digging on this front as well. Thank you.
