I wonder if this could just as easily be explained by an early love for reading. I've heard theories that focusing closely for long periods of time while in your developmental years can lead to myopia.

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).

I am convinced that learning to be a good reader at an early age and bad eyesight is connected. Your eyes weren't designed for reading.

An obvious hunch would be reading a lot, which keeps the eyes focused for long periods at very short distances. Not the way our eyes evolved.
