It's been ages since I read the data, but what I recall from it was that there was a correlation between nearsightedness and early reading, but not proof of causality. That is, kids who read early were more likely to be nearsighted, but it might be true that nearsighted kids were more likely to be able to read earlier partly because they weren't farsighted.
But just because apparently we can't be normal in anything, DS
is farsighted, and
was an early reader. He wasn't a
voracious early reader though, which could have something to do with the farsightedness... but I figure this gives me license to let him read way too long in poor lighting, in hopes of correcting the farsightedness.
He has had two optometrist checkups in his life (at 7 and at 8, different optometrists) and in both cases they said he was at the oldest end of the range when farsightedness was normal... which makes me wonder just how long they intend to let this go before they want him in glasses and just how come they don't bother correcting it now. Since it hasn't really been an "issue" I'm letting it go, but next year we'll be on to optometrist #3.
