Of dark modes, night shift, and tired eyes...
(All About Windows Phone)

Almost all mobile operating system implementations have some form of `night shift` baked in these days - an optional `yellowing` (actually less blue, but you get the idea) of the interface to help reduce eye strain in the evening in dimmer light. I`m a big fan, though there`s an extra question which an American study has tried to answer - does the use of `night shift` visual effects help you sleep once you put the phone down? See below for some quotes plus comments - the studied question didn`t really pan out, but everyone agrees that there are still significant benefits.
