Methods: Participants read for several hours on either e-Ink or LCD, and different measures of reading behaviour and visual strain were regularly recorded. These dependent measures included subjective (visual) fatigue, a letter search task, reading speed, oculomotor behaviour and the pupillary light reflex.
Results: Results suggested that reading on the two display types is very similar in terms of both subjective and objective measures.
There may be, but some studies have shown there's little difference.
