There have been a number of discussions on this topic at mobileread. Inevitably someone will come along and insist that everyone should be able to read on LCD if they just get the settings right.

Personally, I've never had eye problems with eink even after reading for a long period of time, but LCD didn't work out so well for me.

When I got a smartphone last year I tried using it as a reader, but after I spent too much time reading one evening, the next day my vision was worse than usual and I was seeing haloes around lights. Fortunately my vision cleared up by the day after that. I went back to using my eink reader and have not had any further reading-related vision problems.

I believe many people can read comfortably on LCD but it doesn't work for everyone. The only way to know for sure if eink is better for you is to try it for yourself.
