I haven't read all the pages of this thread, but I think my comment is still valid in regards to eye strain.

I have spent the last two weeks grading open-ended responses from 100 students, getting them ready for their English/Language Arts standardized tests in two more weeks. Eye strain comes not only from staring at any form of screen, but in reading paper, too. I have the sore eyes and blurred vision to prove this. (Yes, I am going to the eye doctor to renew my glasses prescription)

So asking if e-readers cause eye strain does not give a true picture, since looking at ANYTHING too long can cause eye strain.

I am grading a set of papers for all 100 students every 2 days, as we are on a 2 day rotation, and I see half one day and half the next. So far this two weeks I have graded 4 sets, with two more waiting for me. phbbbbtttt
