That’s not accurate.
The eyestrain comes from staring at the same thing for too long without your eyes refocusing every now and again.
On top of that people stop blinking as much as they should.
You get just as much eyestrain from reading books as you get from staring at a dark or white screen if everything else stays the same (time you stare, how much you blink).
Because books reflect light while screens generate light so white paper doesn’t cause the same eye strain as a bright white screen.
