I recall studies showing that reading in poor lighting conditions is a cause of myopia in children. So I'm questioning whether we want to be reducing luminance on our devices at all.
I like my (warm-coloured) lights and screens set to max brightness. I find it's easier to read and lets me work with more distance from the screen.
But what about easier sleep? Could we exercise more? Leave screens out of the bedroom? I have no idea.
- zargon 8mo agoSignificant 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.
- avadodin 8mo agoMain 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.

- zargon 8mo agoI agree that genetics can protect you from developing myopia. For people who are genetically susceptible, outdoor exposure is critically important. Most people won't know which group their children are in.
- avadodin 8mo agoLet's just say I knew soon enough for the ones that were in the myopic group. It's not that I don't believe these studies or that I don't recommend children and even adults going outdoors and trying to watch something far away without glasses whatever their supposed genetics may be but I think it is nowhere close to a silver bullet.
