Do E-Readers Cause Eye Strain?
Michael Bove, director of the Consumer Electronics Laboratory at the M.I.T. Media Lab, says different screens make sense for different purposes.
"It depends on the viewing circumstances, including the software and typography on the screen," said Mr. Bove. "Right now E Ink is great in sunlight, but in certain situations, a piece of paper can be a better display than E Ink, and in dim light, an LCD display can be better than all of these technologies."
