Results: In 1958 Nadell and Hirsch found that children in America with myopia have a higher IQ. A similar relationship has been described by other researchers from the USA, the Czech Republic, Denmark, Israel, New Zealand, and Singapore. In other related studies, it was reported that myopic children regardless of their IQ gain better school achievements--table 1. It was also observed that schoolchildren with hyperopia have a lower IQ and gain worse school achievements--table 2. Several hypotheses explaining the relationship between refractive errors and intelligence have been published. Recently, Saw et al. concluded that higher IQ may be associated with myopia, independent of books read per week, in schoolchildren. According to them "the association between genetically driven IQ and myopia of hereditary predisposition could be forged because of a pleiotropic relationship between IQ and myopia in which the same causal factor is reflected in both genetic traits. There may be similar genes affecting eye size or growth (associated with myopia) and neocortical size (possibly associated with IQ)".

Conclusions: The conducted clinical observations suggest that children with myopia may have a higher IQ. This relationship is most probably determined by genetic and environmental factors.

Funny that may be why cartoon nerds wear glasses, e.g. Poindexter.

I had myopia until recent LENSAR cataract surgery; for extra dough they correct your vision with the laser while they're zapping the cataract.

I love being able to buy cheap sunglasses and now I've got a fetish and a small collection (6) which cost less than 1 pair of my Rx sunglasses

Check out: Knockaround from San Diego. I also have Sunski from San Francisco, and one pair of eBay Revos for 60 bucks.
