Eye strain isn't from the colors - it's from the brightness of the screen switching and if the screen is the only light source in the room your eyes has to constantly adjust to new brightness levels.
To avoid eye strain - turn on a small lamp in the room. Make sure the ambient light in the room is not zero. That's way better. If anything I'd think this make it worse - the brightness of the whole room changes constantly making your eyes having to adjust more, not less.
