Night mode

Night mode on versus off.

Night mode is a feature on a computer or smartphone that reduces eye strain from blue light. It does this by lowering the amount of cool-colored light emitted from the screen. It takes these blue, green, or violet tones, which can cause strain to the human eye, and replaces them with warm tones like red and orange to reduce their intensity.

Note

Night mode is not to be confused with dark mode, a feature intended to solve the same problem by changing white and light grey pixels to black and dark grey ones.
