Does scattered light reach your eyes? Uh...no. Light reflecting off of paper that is scattered...misses your eye. If the light makes it into your eye then it's at the same angle as any other light making it into your eye.

What you get from reflected light is it's AUTOMATICALLY at the level of the ambient light. People already tend to have room lighting that's comfortable, ergo, the reflected light is comfortable.

So just turn your tablet/phone light to match the room light level, or any level you find comfortable.

Or just take a megawatt light and shine it on your book and seek if your eyes don't smart. Cuz...you know...it's not about reflection, but light level. You go outside in light so bright that it hurts your eyes...you won't be able to read a book comfortably in that light either.
Precisely my point. There is exactly zero difference between directly-emitted and reflected light as far as your eyes are concerned. It's all about light levels, not the path by which the light reaches your eyes.
