Surprisingly, yes. We discussed this back around the end of July
last year, and I posted a note on July 24th, 2000 about it.
There's a significant relationship between myopia
(nearsightedness) and variables such as IQ, educational
attainment, and amount of time spent reading. The smarter you
are, or the greater your education, or the more time you spend
studying, the more myopic you are. And vice versa. Me, I'm so
nearsighted I can only see behind me.
And for once the correlation seems to be causal. Nerdish
activities promote elongation of the eyeball, a primary cause of
myopia. This was established in studies where rats were forced to
read the speeches of George Bush and Jean Chretien until they
could no longer see well enough to solve mazes. Predictably,
animal rightists protested, not because of the harm to vision but
because no animal should be subjected to that kind of abuse.
