"Viewing a video display terminal screen is different than viewing a typewritten or printed page. Often the letters on a VDT screen are not as precise or sharply defined, the level of contrast of the letters to the background is reduced and the presence of glare and reflections on the screen may make viewing more difficult. Viewing distances and angles used for VDT work are also often different from those commonly used for other reading or writing tasks. As a result, the eye focusing and eye movement requirements for VDT work can place additional demands on the visual system. Older workers particularly may find adjusting to these working requirements difficult."
This has nothing to do with the type of display. But it is worth noting that the Nook Color has better contrast and pixel density than the e-ink Nook in most indoor lighting conditions.
Personally, I get more eye strain from my e-ink Nook than I do from my PC at work because of the Nook's poor contrast in dim lighting (although the 1.5 updated definately helped that out). Two 40 Watt bulbs above my bed aren't quite bright enough. It's not bad enough that it bothers me, but it is noticeable.
Overall, for my reading the Color is a better choice. I think that's going to be the case for most e-reader buyers however of course that doesn't mean it's better for everybody.
