Actually, eye-strain is caused by the inconsistency between the display and your surroundings. That include not only brightness, but also colors. |

My house has poor lighting, and I read on my kindle during the day, but after dark I read on my backlit iPod. The last time I experienced eyestrain was, while reading a paperback with too small font - rather dark paper (yellowish)... I gave up reading novels altogether until I got my Palm. |

Whether or not LCD causes eye strain is completely moot for me. I simply find it uncomfortable to read on LCD. I don't know what causes the discomfort (and I've tried lowering brightness, etc.). I used to read on a PDA, and I've tried reading on my phone, but I could only ever manage a little bit at a time.
I spend much of the day at a computer screen, and that doesn't really bother me. I put that down to the nature of the reading. When reading in short bursts and constantly shifting focus and interacting I don't feel any discomfort (though I do occasionally get tired eyes, but that is possibly the harsh lights). But trying to read anything longer than medium-lenght article just feels so wrong that I usually have to stop before I've finished. However on e-ink I can keep reading for quite a long time. It just feels more natural. I'd love to see some proper scientific study on this, but I will use whatever device works best for me. But I think people have different preferences and different eyes. To say that LCD is as good for reading as e-ink is dismissing the fact that some people cannot bear to read on LCD. And to say that LCD is damaging to one's eyesight is overlooking the fact that there is no scientific data to back that up (that I'm aware of). There is plenty of technology on the way that makes this moot anyway. Pixel QI's screen apparently looks comparable to e-ink when in that mode and like full colour LCD when in LCD mode. The company that makes Kindle screens has apparently got colour e-ink with refresh rates capable of high enough framerates to emulate video. These displays are probably going to make LCD obsolete for any portable device due to their efficiency and flexibility. I certainly will be thinking twice before buying any device with an LCD screen in the coming year. |

So when I got my iPad -- and my eyes SCREAMED -- I tried what the researcher suggested. Lo and behold, no more eye strain. Nonny |

Eye muscles react to light intensity, to distance, to object clarity, and to differences between the point being focused on and the surrounding visual data... all of those elements cause the eye muscles to work to compensate for them. The more the eye muscles have to work, the more fatigue those eye muscles feel. Everyone's eyes are different, and some eyes react more to one stimulus than to others. To some, the lack of contrast in e-ink screens can be as fatiguing as the wrong light intensity on an LCD screen. That's just one reason why some people can read more comfortably on an LCD screen than an e-ink screen, and there are others. To reiterate my earlier point, any claim that one display technology is better than the other is purely subjective. What works for you, works for you. |

It's not where near that bad if you keep the backlighting to the proper levels for the conditions you're reading in. Use a darker background like sepia etc. I get that e-ink is great, especially for people like the guy above who mentioned reading 16 hours a day etc. With super heavy reading, even minimal differences in eye strain add up, and it's important to read on what ever gives the least fatigue possible. Where as it doesn't much matter for a casual reader for me who reads maybe 1-2 hours a day on average, and often less than that. As I've said repeatedly, it's great that we have all these options to pick from so we can all find what we want. People that read tons and tons every day, don't spend much time on other media hobbies (TV, movies, music, games etc.) have e-ink readers as their ideal device. Someone like me that doesn't read that much and is more into movies, tv, sports, video games etc. has devices like the iPad and other tablets that are more in line with our needs. Again, it's not some zero sum end game where only one type of e-book displaying device can survive. Tablets aren't going to bring about the death of your e-ink (or other reflective screen) reader devices. Thus there's no reason for people to be so antagonistic against LCD screens. It's fine that people don't like them, but no need for all the "if it glows it blows" type of hatred toward LCDs we get on here. Different strokes for different folks. One can read on what they like, and discuss why they prefer it with out being super defensive and antagonistic. |

My eyes are burning when I'm reading on a too bright LCD and my eyes are burning as well when I'm reading a book or magazine (especially the glossy ones) in direct sunlight. Conclusion: brightness is not good for my eyes. So I dim my LCD and I'm fine. End of story.

If it's actually eye-strain then it's caused because you're using the device too often, or any of the reasons mentioned in the original post (too bright, wrong distance, etc.) Experiment and find out what works.

That still doesn't make one better than the other... especially as the majority of those preference comments are anecdotal, without verifiable scientific data to back them up. There are no solid "statistics," and "it appears that" doesn't settle the matter.

The sales figures for eInk screens are solid statistics, as those (equipped with eInk screen) devices are ill suited for anything else except dedicated readers. |
