Seems to me (as a total layman) that the contrast between a brightly lit screen and darker surroundings would force the eyes/brain to adjust every time that you glanced away from the screen - giving rise to eye strain at least. A non-backlit e-ink screen, being the same brightness as the surroundings, wouldn't have that effect.

OK, lets hear from the experts again................

Put the two types of screens next to each other in full sunlight.

I wouldn't be so sure about that if I were you:

The good controlled data I've seen so far is that there is significant melatonin suppression after two full hours of staring at an iPad at full brightness before bed. Which no-one in their right mind ever does. No statistically significant suppression after one hour, even at full brightness. This doesn't mean that individuals who are particularly sensitive won't have effects at one hour, or that there may be other mechanisms.

I know that my Glo emits a lot less light than my iPad, even when I dial brightness way down on the iPad. Night mode may make the difference for some, but I (like many others) can't read light-on-dark text well. Perhaps more importantly, the Glo is a lot, lot less blue than any LCD screen I have.

As neuroscientist Mark Changizi put it in a blog post:

" In nature, information comes with a physical address (and often a temporal one), and one can navigate to and from the address. Those raspberry patches we found last year are over the hill and through the woods — and they are still over the hill and through the woods.

And up until the rise of the web, the mechanisms for information storage were largely spatial and could be navigated, thereby tapping into our innate navigation capabilities. Our libraries and books — the real ones, not today’s electronic variety — were supremely navigable."
