The tech outpaces a trial? How long does it take to have people read for a few hours and report their eye strain? This isn't healthcare research where survival over a human's lifetime is critical to study.

If your eyes hurt more it is almost certainly due to poor reading habits.

So I have poor reading habits on LCD but not on eink or paper books? I'm supposed to change my reading habits when I read on LCD? The expert quotes I've seen say to take a break from LCD monitors every 20 minutes. This is not the case with eink and paper. I can read eink or paper for hours without eye strain. With LCD my eyes get tired within an hour, and the larger the screen the faster it happens. I tried playing Oblivion on a 32" HDTV as a PC monitor and I was worn out in 10 minutes.

The phenomena is completely understood.
Likewise, there's no voodoo to LCDs, they've been around for decades (longer than e-ink for that matter if you want to ascribe black magic to anything). ZERO experts advise dumping LCDs in favor of e-ink for the sake of your eyes, they ALL simply advise better viewing habits. Good habits, no worries.

As a computer programmer, I suppose I could resort to punch cards during my "good habit" breaks every 20 minutes of screen time. But I'd prefer a less straining display technology. Whether that technology comes in the form of less light, a different way of delivering it, or a way to induce proper blinking, I'm not sure what's best. But I know LCD isn't it because I've tried the superior alternatives. Anecdotally, anyway.
