Why hasn't his teachers noticed he can't see?
There are so many things going on in early elementary, I would necessarily expect a teacher to notice - you hadn't noticed at home either. We were also told that changes in eye-sight can happen really quickly when children are young (early elementary age). The one person at school I would expect to notice would be the school nurse - our school district has the school nurse screen each child's eyesight once a year, and I'm guessing if they were near-sighted a note would go home.
That said, our ds is color-blind, the school tests for that, and apparently realized it, and didn't bother to tell us.
And... re teachers not noticing... or nurses when screening... our oldest dd had severe double-vision and lack of peripheral vision in early elementary, and none of her teachers *ever* notice (neither did her parents). The signs were all there, but none of us knew what to look for or realized we should be looking for anything
When we found out at the end of 2nd grade, through a round-about eval brought on by concerns over academic struggles... our dd just looked at me like I had three eyes in my head and said "Of course I see two of everything... don't you?" So that may be part of why your ds didn't say anything to you about not being able to read what's written on the white board - at his age, with his life experiences, he might have been thinking that's the way everyone saw it.
Let us know if correcting his vision helps with school!
