Myopia and IQ (From Wikipedia)
Many studies have shown a relationship between myopia and IQ. According to Arthur Jensen, myopes average 7-8 IQ points higher than non-myopes. The relationship also holds within families, and siblings with a higher degree of refraction error average higher IQs than siblings with less refraction error. Jensen believes that this indicates myopia and IQ are pleiotropically related (both myopia and IQ are caused by the same genes). The mechanism that has caused a relationship between myopia and IQ is not yet known with certainty (Jensen, 1998).
