so the screen is normal during daytime, and dimmer/warmer at night,
with a gradual transition during twilight.
For Android phones and tablets: "twilight"

(15,093 posts)My wife does this. She will spend hours reading books on her iphone at night. I just go to sleep when I'm tired, and don't pay any attention to the phone till morning (do not disturb mode is great).
Of course, I grew up in a world without email or smartphones, but so did she. Guess I'm just a ludite.....

Just a different light source. Use of a retinal screensaver recommended.
