Eye-Strain on LCDs is a Myth (or missunderstood)
Eye-strain is not caused by the fact that a screen is backlit.
A Paper-Book shines light into your eyes the same way, by reflection. Eye-Strain is caused by: - too much brightness. Your screen should not be much brighter than your Surroundings. - other bright Light-Sources in your viewing area. Bright Lights should be above you or behind you and shine straight down only. Look at Office-Lights, they have Grid-Reflectors for this reason. - Wrong Distance to monitor. If you have read alot of Books, your eyes might have permanently adjusted to this small Distance for reading (thus the eye-glasses to correct this) and reading at a bigger distance requires eye-muscle work and those get tired quickly causing the sensation of eye-strain. Eye-strain is always a muscle-issue, there is nothing else in your eyes that could cause this sensation. I had huge eye-strain issues myself and even gave up Desktop-PCs completely (Laptops were fine) until i noticed the importance of all these 3 Factors. |

You failed at your own little joke. It would be propaganda from the other side, the e-ink manufacturers.

I'll tell my eyes that eyestrain from backlit screens is a myth.
Meanwhile, I'll avoid reading on backlit screens both handheld and monitors because my eyes believe the myth. In other words, I can tell the difference and will stick with non-backlit screens for most of my reading. |

I vastly prefer e-ink devices for leisure reading, but it has nothing to do with eye-strain.
I think people confuse the different feelings they get from e-ink and back-lit screens as strain. An avid reader who is used to paper books will feel different when they read on a back-lit screen. Paper isn't back-lit so they feel more comfortable reading on something that isn't back-lit, simply because it's familiar. When I read on an e-ink device I will often "forget" that I am not reading a paper book. When e-ink first came out, several people would make comments about how they would find themselves attempting to turn a page instead of clicking a button. |

Anyway, why did you feel this needed another thread? Madam Broshkina - Except for the minor fact that eyes do NOT refresh in a linear manner. Actually, pushing CRT refresh rates much above 100Hz causes a "shimmering" effect for many people. |

I think that my issue is that when staring at a backlit screen, I focus very intently and forget, on occasion, to blink as often as I should.

(1) Using a back-lit device for an unfamiliar purpose (2) Doing something familiar on an unfamiliar device (converse of 1) (3) They retain the "computer" mindset when looking at a "computer" screen (i.e. the feeling that you need to be doing several different things at once) |

@TallMomof2
i want everyone to read comfortably, but ask yourself what is the difference between Backlights and reflected Sunlight. If its not the "Nature" of the light, then it must be something else, and the only differences i can see are these: - Reflected Light can not gain Intensity (-> lower Brightness) - E-Readers are much closer to the eyes than typical LCDs (-> adjust distance) - avoid additional eye-strain (muscle-fatigue) from other Light-Sources (tightening the iris is additional muscle-work for the eye, thus the muscles get tired even quicker) It would be interesting to know if those who suffer from eye-strain also dislike too much sunlight. I do. |
