Ted McCagg's advice:

Glasses

As someone who started wearing glasses about a year ago, I've wondered why we associate intelligence with glasses. According to Wikipedia there is a genuine correlation:

A number of studies have shown that the incidence of myopia increases with level of education[63][66] and many studies[70] have shown a correlation between myopia and IQ, likely due to the confounding factor of formal education.

I imagine this correlation is based largely on environmental factors. According to my eye doctor, my myopia was probably caused by eye strain from reading blog posts ten hours a day for a couple years. Anyone have better research?
