It's funny, I was just thinking that except in reverse. I've found the flash on my PRS 350 very distracting compared to my Kindle Keyboard this week. I've no idea if one is any 'better' than the other and just figure my eyes are more accustomed to the Kindle so I don't notice it the same, whereas I use the 350 less often so the flash irritates me a little at times.

Scientific studies say backlit or e-ink does not make a difference in terms of eye strain.

e-ink and backlit lcd are the same in terms of eye strain....
this is not the topic that I'm talking about But all the people here would disagree about this claim, AND one study does not give you the right to say that this claim is "scientific". What kind of light do you prefer to read on the kindle? |

I've owned many Kindles, and many external lights. By far my favorite is the integrated light of the Kindle Paperwhite. Both my former K3 and K Touch had the Amazon covers with integrated lights, and those were fine. The Octovo Solis for the K2 was my favorite non-integrated light for any of the units. It was specific to the K2 in that it fit snugly at the top of the unit. It didn't fit any other Kindles properly. I'm not sure Octovo is even in business anymore.

Hi Meera,
The work was performed at the Institute for Research in Open-, Distance- and eLearning, Swiss Distance University of Applied Sciences, Brig, Switzerland, and GfK Switzerland AG, SirValUse, Biel/Bienne, Switzerland. I don't know what the second one is -- maybe a company? No funding is listed -- just an acknowledgment of the Swiss Distance University of Applied Sciences (Fernfachhochschule Schweiz, FFHS). Best wishes, k4k |

GfK Switzerland AG is a market research institute, which suggests that business did have its fingers in this study to some extent. Hm.

If I find 10 chain-smokers that are 90+ years old, does that mean that smoking might not be all that dangerous? I think not. |

I'm sorry, I didn't mean to open a can of worm and upset all those who believe that e-ink is better for their eyes! It's just that I am a scientist and normally search for evidence on pubmed rather than reporting what happened to me, to my mother or looking in a blog...
My fault, I misunderstood the question of the first post - I had thought he feared that e-ink might bothers his eyes and I pointed out that the only scientific study in biomedical journals I could find says e-ink is as safe as backlit for your eyes. I own an e-ink reader myself. Not because I think that backlit devices give me red eyes (I stare most of the day to a computer and have no problems at all with it) but simply because I find it more similar to paper, that is it looks nicer. |

I am not saying this study was designed that way. But if I personally wanted to demonstrate no significant difference when a real difference exists, as well as keeping the sample size low, I'd do things like set up older e-ink devices under sub-optimal lighting in an imperfect font, and compare that to brand new retina-screen tablets with the most readable fonts and the brightness, backgrounds and contrast tweaked just perfect. And then write the methodology section carefully to conceal most of this. |

What did they try to show? It is either: a) eink is just as bad as lcd or b) lcd is not any worse than eink |
