I think about this every time I use my phone or watch tv at night. My TV doesn’t have a redshift setting and my iPhone has Night Shift, which I have turned all the way warm, but even that still feels like it’s not warm enough. It would be great if the iPhone had a setting to just go red monochrome... Like F.Lux’s darkroom mode.
I personally always thought green text on a black screen is the way to go!
