The others are right this is an endless cycle, although I want to be clear that I do not discount anyone's experience with eyestrain (yes even the rude lady above). I stand firm that ebook devices can exist for both sides of the argument and it is personal choice that is the deciding factor (and for some of you a medical reason is clearly part of it).
Later all, have a good chat. |

Maybe if you sleep it over and re-read your posts again you might notice it. |

I'm not bullying anyone. In fact, Astra, a couple of your posts came off that way towards me. All I did was make statements about LCD, although passionate, were just discussion points. I'm through talking about it now, I apologize to anyone who took my posts personally. Its interesting though, that you chastise my responses and yet you ignore the tone and bad language in the post I responded to. So basically the point I get on the board is "believe as I do or don't say a word." If someone feels passionately about a subject they debate it. That is partially what a discussion board is for. No where in my posts did I make personal attacks, as some here have done to me because I do not feel as they do.

a) my eyes hurt when the only light source is a screen of iPhone, set to minimal brightness, in complete darkness, and b) they don't hurt when I read on e-Ink, in full sunlight or under bright light of the lamp tell you about relevance of the symptoms I described to light sensitivity? Quote:

Wrong - I haven't used any for years now. When they were still around, I wasn't able to use them as they caused headaches. Please read more carefully. Quote:
EDIT after some time: Actually, I'm serious - if you see anything in my first post, which contradicts something else in the same post, I'd be glad if you could point it out to me. As almost everything in the post is a summary of what effect reading under various condition has on me, I don't understand how it can be contradictory.

1. I'm 43 and have been using computers since I was 11. First one was a TI-994A, which you likely have never seen in your life. CRT monitor. It never bothered my eyes. 2. Apple 2E - CRT no troubles. 3. various IBM clones - CRT no troubles 4. MAC and PC computers from CRT to LCD - NO PROBLEMS with my eyes 5. Started reading ebooks on my handspring visor. Small, but my eyes never hurt. Greenscreen and backlit. 6. RCA ebook reader. Reading many many books. No problems no headaches. 7. ebookwise-1150 reader. Virtually same machine as RCA. No problems 8. iPAQ PDA - LCD no problems. 9. Sony PRS-505 eink. No backlight, didn't fit my needs. Still have it. No problems. Still like eink. 10. SmartQ7 Tablet LCD - no problems 11. WitsTech A81 Tablet LCD - no problems 12. 2 different ASUS netbooks LCD - no problems 13. SmartV7 Tablet LCD - no problems 14. iPod Touch 3G LCD - beautiful display no problems at all 15. Pandigital Novel LCD - crisp screen, slow interface, no problems with eyes 16. Blackberrys of many models to read, LCD - No problems 17. The above is not the complete list of devices I have used or own. I still have almost all of the hand-held devices on this list. I'm a programmer. I have been since I was about 15. I am on a computer for way too many hours every day. It started on CRT and now I use LCD. I have 20/20 vision and have no problems. So there you are - my contradiction to your post. Nevermind all the other people here who have been saying the same thing in this thread. Yeah, thats what I thought. And yeah, I'm just like you, I'll defend my point to the end that LCD does not harm your eyes. That eink users do not all want eink screens and may choose something else because the market only released new reading dedicated eink machines for the last few years. That LCD causing eyestrain by itself or will shoot laserbeams into your eyes is a myth. I feel just as passionate about my opinion as you and if you are going to come at me about it you better have some facts of your own, other than your sweet personal preference loaded with misinformation about the technology itself. P.S. I was ready to stop posting in this thread but you are exactly the kind of eink user that pisses me off. You ignore everyone else here that posted that LCD was fine for them and caused no problems and because YOU have issues with it you dismiss the rest of us. Don't you see that my posts did exactly the same to you? And you got pissed right? Try the shoe on the other foot for a while and see what I mean. You might find these articles helpful. http://www.allaboutvision.com/cvs/irritated.htm http://bits.blogs.nytimes.com/2010/0...pagemode=print http://library.thinkquest.org/C0123325/synd.htm Try adjusting your contrast and brightness to acceptable levels. Change your settings from white background with black text to white text and black background. There are many things you can do. Either way, read those articles and the one at the beginning of this thread and get back to me. Last edited by ColdSun; 10-31-2010 at 02:58 PM. |

For the pain and headache, it isn't necessary that all the receptor cells in your eyes feel the same large number of photons, a small area on your fovea (the part of the retina where the image of letters will be formed) is enough. And at the center of the fovea there are around 150,000 receptors /mm^2. The fact is that you are not going to read you E-Ink in a completely dark room, and the amount of light that is scattered of the capsules of ink will never rival the light emitted by the LCD in terms of photons/mm^2 on your retina. |

The discussion all started off with a CNET article with the author calling up his own personal ophthalmologist as an expert witness who declares that today’s LCDs will not cause more eye strain. However, I’ll take his statement with a grain of salt. The medical community had insisted Hormone Replacement Therapy f(HRT) for women would not increase the risk of cancer even though there were prevalent statistics supporting the opposite. Finally, a carefully monitored program was administered to a group of poor women by giving them HRT. Midway down the program, a significant number of the poor women in this experiment developed breast, uterus and ovarian cancer and the program was terminated hastily. Even though I personally do not have a problem of working and surfing the web with LCDs, the statistical importance of people stating otherwise in this forum or in other boards cannot be ignored. In fact, the voting poll in the same CNET article shows out of 1236 people who voted, 70% prefer e-ink, 11% prefer LCD and 19% no preference.
I researched the subject more on the internet and most of the discussions are focused on personal experience and a lot of debate. However, I did find the following bio-medical scientific study published in 2006: http://www.biomedcentral.com/1471-2458/6/303 A study was conducted on 319 light-on test workers of the TFT-LCD display. The study found a high prevalence of eye discomfort among the workers and most common symptoms were eye dryness (43.3%), eye itching (32%), eye pain (11%) and blurred vision (10.3%). A similar study on VDT (video display terminal) workers in Taiwan also found the most prevalent problems were eye strain (82.4%), eye dryness (52.9%), eye itching (52.9%), and blurred vision (50.0%). Even though common users are different from long term VDT or LCD test workers, the study does seem to support eye strain related problems for some VDT/LCD users. I have preordered a Nook Color so I’ll report back if I have similar eye strain problem reading on the LCD. I have headaches reading with the e-ink or even paper in low light but I do not have problems staring at the LCD at work and from home for 12 to 13 hours a day, However, I haven’t read a book on any LCD reader yet so it might be a totally different experience. |

Some of this simply comes down to common sense. We are not cats who's pupils become huge to see in the dark and shrink to slits in very bright light. If you have trouble seeing, in low light turn on some lights. If you are holding an e-ink close to your face to see clearly, see a doctor about glasses. Take a break from the screen and blink a few times to moisten the eyes, dry eyes = pain/strain. Don't read in the dark whether with an lcd or e-ink. In very bright light outside, wear sunglasses, excessive light can also cause strain & pain. Don't expect your bodies to do extremely more than they are capable of and then complain when they start hurting. |

Just more stuff taken from other articles. Maybe this can help some LCD people who want a good reading experience:
