Also note that another aspect of the 'LCD vs e-ink' controversy is flicker. Even reflective LCDs have the flicker issue.
LCDs flicker, and *that* is tiring to the eye. E-ink is static -- it stays exactly the same until it is changed. It doesn't have to be refreshed until the image itself has to change, typically at page turn. The same is true of other dynamic screen technologies like OLED. |

I was asked by a naturopath, who wants a reader, to research the light emitted from them because blue light has a direct affect upon the melatonin levels in the body which affects circadian physiology, alertness, and cognitive performance levels. Strangely, I found this study which points to the need to design a computer screen with a spectral profile that can be individually programmed to add timed, essential light information to the circadian system in humans. I say strange because I found the study half hour after I downloaded a program for the Mac that modifies the computer screen with a spectral profile that can be individually programmed to add timed, essential light information to the circadian system in humans. Anyway, I don't suppose anyone knows of a light emitting reader that can be programmed similarly, so night reading doesn't make you drowsy . . .heh! |

I have a laptop and have read Kindle books on it. That hasn't hurt my eyes. PDF is more difficult to read on the laptop.

I personally find the e-ink to be much easier on the eyes.

For reading I much prefer the eInk screen to backlit screens of a tablet. For books anyway, for magazines or reading online content its the exact opposite.

I took a relation to the Low Vision clinic at our local hospital and asked if they had a preference for e-ink over lcd. They said it was a personal to the individual. I asked if an Ipad screen would damage a persons eyes and they said no.

I've had CSR in the past (retina condition). When I had it I found my ipad much easier to read. In fact, it's why I bought and ipad. I had gotten to the point my K2 was hard to read. Now that the condition is cleared, I've gone to a K4 and hardly use the ipad for reading anymore.
