What about the the blue light emissons?

  What about them? (E-)Paper reflects blue light, LCD backlight emits it. The only difference is that the color balance and brightness don't change with the sunset on your screen unless you install a tool like flux. Light is light. Looks the same = probably is the same. Bands are just a bit narrower with LEDs, but I wonder if that makes any difference biologically if it looks the same.

    With a backlit monitor (or projection screen) your visual system is doing extra work to reconcile two different lighting conditions. eink/epaper is reflecting ambient light just like every other object in the environment so your vision won't need to adjust when glancing back and forth

      Yes, e-paper auto-adjusts. But so do phones if they are set right (best done with a matte screen).

      This sounds like your monitor is set too bright. (Or less likely, not bright enough.) If you set your monitor to the same brightness that paper or a non-backlit screen would have in your room, then your vision doesn't have to adjust to the different brightness levels. Same for TV. Don't watch TV in a dark room! When I had a modest home theater with a projection TV (the old bulky kind, not a separate projector and screen), one of the best things I did was to light the white wall behind it with a soft neutral gray light. The technique at the time was to use a small fluorescent desk lamp on a small table behind the TV, with the fluorescent tube wrapped in a specific color of lighting "gel" to make it a neutral gray. The lamp was aimed up at the wall behind the TV. This made everything much easier on the eyes.
