It may seem ass backwards but there is a reason I am drawn toward non-lit screens. The main one is that I have light sensitivity. I get ocular migraines fairly frequently which I believe may be caused or partially caused by staring at bright screens. I frequently have to turn the brightness down on my smartphone. A lot of times I will use my old TI calculator to do math if it means 30 seconds where I am not staring at my phone calculator app with its white background.

The only gaming devices I can think of without a lit screen are the original Game Boy family (minus the AGS-101) as well as the Tiger Electronics ones.

I just wanted to shine the spotlight on a health-related problem that others may have. I think it's a shame that so many Game Boys are being modded to have the screens upgraded (downgraded) to LCD displays. Hell even the worm light and Light Boy are better solutions for me than modding.
