Hopefully he really is 20/20, but testing vision is always hard. We tried the letter chart first but he's not completely reliable with letters. So then we tried the shape chart but he's too creative for us to reliably understand what it is he can really see.
He'd call the same shape 3 different things depending on which time you asked him. 
"It's round. It's a zero. It's a moon. It's an O."
"It's a flag. It's a computer."

Anyway, he's great. A healthy little boy that has his physical complete and is ready to start Kindergarten in the fall.
