Significant outdoor exposure is essentially the only relevant factor for preventing myopia. I would be interested in seeing any studies that showed any meaningful relevance of low light reading, while controlling for time spent outdoors.

Main factor is genetics.

I was gaming on a blurry CRT and reading on a dim light while hardly ever going outside during my teens and I only have light myopia on one eye.

I don't know if it has ever been studied, but I suspect eye socket morphology from my own family anecdata.

large eyes + small socket = squashed eyes.

It could be different genetic factors for different populations too.
