Again--if you're referring to an e-ink screen, as Harry pointed out earlier, they are not back lit. They are front lit. meaning the light comes from LEDs situated in the front of the screen, it's not being lit from behind like LCD screens.
Personally (based on my personal experience only not any studies), I don't like reading on my iPad before I go to sleep. On the other hand, I enjoy reading on my Kobo Aura HD and Kindle PaperWhite (both front lit e-ink screens). To me, reading on the Aura and PW in a dark room is similar to using an external light source.
