This is why I always have two devices now, one eInk for daylight/sunny/brightly lit indoor & outdoor reading, and something with an integrated backlight(color or mono LCD, mono being more versatile as it's also useable in the same cases as eInk) for poorly lit/night conditions. DPI is nice to a point, but remember I started off with a very low res/low DPI IIIx so this doesn't bother me as much as how lighting conditions affect overall readability/usefulness. I also decry non-easily user-replaceable batteries(gTab , NC, iPad, etc.). Bottom line here until Pixel Qi and/or mirasol screens become de facto standard on readers/tablets I'm ALWAYS going to want options. Forgot to mention the relatively slow refresh of eInk screens, which some people find to be so annoying/distracting that they will NEVER buy current eInk devices... something which doesn't affect LCDs, excepting very old ones which exhibited "ghosting" effects, but those are long ancient history and even the cheapest LCD screens have pretty performance characteristics today... |

For what it's worth, I personally carry my eInk Nook with me wherever I go and use it to read novels.
I only use my color Nook at home, and then mainly to read graphic novels, manga, and watch movies. my two cents worth... |

Astigmatism is a physical distortion of either the cornea or the lens and accrediting the media upon which you read as a cause is as ridiculous as saying a glass window will distort if you look thru it constantly. Kind of like when my dad always said (as a joke, of course) that if you try to shoot a .22 as far as a .308, you'll strain the barrel of the .22. |

LCD's cause eyestrain..

EInk is easier on your eyes. Different people will notice it to varying degrees, just like some people notice the difference between a big mac and a good steak and some don't (not that the NC is a big mac). I love my Nook Color for web surfing and watching videos, but I read books on my Sony 350 or Kindle 3. My eyes are grateful when I switch back to an eink device, yours may not see the difference. The Nook wins in certain areas and loses in others, mainly readability for me. Actually there are a LOT of things about the Nook that could have been done better (pinch zoom, forward btn in browser, better speakers and volume), but for the price point I think it's a good value and I'm happy with it. |

So how does one know that astigmatism came from an LCD?

Because you are forcing your eyes to read and focus, and focus, and focus several times, ending with that particular problem. LCD produces an artificial light that creates glare and eye strain.
Please, why people can be so passionated about something? Gosh! ... my own doctor just confirmed this to me. If you read or use your NC for extremely short period of time you are not forcing your eyes at all. But the minute you start using such devices for several hours, several days during the whole week, the whole year, everything change. And with no doubts you are not going to use your NC for 30 min a day and turn it off until next day, are you? What do you guys want or need to believe it? A signed document by an ophthalmologist? Anyway, I move on on this topic...honestly ... Last edited by jocampo; 12-20-2010 at 04:24 PM. |

FWIW --- Directly from the Mayo Clinic: Astigmatism is a common, mild and easily treatable imperfection in the curvature of your eye. The condition can cause blurred vision.
Astigmatism occurs when the front surface of your eye (cornea) or the lens, inside your eye, has a slightly different surface curvature in one direction from the other. Instead of being even and smooth in all directions, the surface may have some areas that are flatter or steeper .... In most instances, astigmatism is present at birth. Sometimes, astigmatism develops after an eye injury, disease or surgery. Astigmatism isn't caused or made worse by reading in poor light, sitting too close to the television or squinting. |

FYI, there are several types of astigmatism, one of them is the one created by eyestrain and the continue use of LCD devices. |

You just can't let it go, can you? How is that particular "strain" of astigmatism identified?

I did not have this problem before and I was not born with such eye problem. No one on my family (dad or mom) had astigmatism. I started working with computers at 1994... soon after .... I developed astigmatism. It was confirmed by two doctors, one here in USA, another one on my country. Actually, because same reason I need to take short breaks from monitors and LCD displays in order to avoid the problem getting worse. |

I'm busting your chops because when other people say their experience is different from yours or those of people you know, you always make it seem as if they're not being honest. Now you know how it feels. |

Um....No.....the ophthalmologists at THE MAYO CLINIC knows more than "your" opthalmologist. Astigmatism is a physical abnormal curvature of the lens and cornea, which is not caused by eyestrain, although astigmatism can CAUSE eyestrain. Last edited by leday; 12-20-2010 at 04:54 PM. |
