When ereaders came out similar to books!
I believe a study done that tested how long the eye stays focused at the same distance would show typical LCD screen usage to have a much longer duration focused at one distance than book reading... And thus kindle etc too.
I also believe LCD portable devices Sit somewhere in the middle of that range.
After all what your looking at can't cause strain but it's what that causes the muscles of your eyes to do.

And the programmers/designers don't help either. When we program something, we're bound to conventions.
That is... keep the important data focussed in the center of the screen. Take a look around. Your browser, the websites you visit, the programs you open. All make you focus on the center of the screen.
Everything is designed to make your eyes moves as little as possible (small paragraphs on websites)
Of course people would focus more then... For a book, your eyes will move from up to down. For a website, you'd just scroll the page.
