Or geek - There's more to it...
There was another article a few months ago that studied myopia amongst Asian students, due to rates that are seen as high. It was suggested there that myopia, rather than being inherited, was a result of lack of exposure to light. Students with myopia didn't tend to get out as much. Science can have have trouble qualifying things that are a result of more than one reason. experiments that support or prove theories, are better if only one thing can change. They are missing the point. The reason geeks, and nerds don't 'socialize', or 'get enough light' isn't because they are unsociable, but perhaps because they 'travel' in a different social circle, which is cyber, and global, through the internet. Perhaps they can develop terminal screens that emit the wavelengths of solar radiation so chronic computer users avoid developing myopia.
