I never said I didn't use CRT monitors. If you don't know English well, you might have been misled by my statement "I haven't used any for years now". This means that once I did use CRT monitors, for short periods of time, but I stopped using them long ago.

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.

I'm not sure if you realize that you aren't making any sense.
1. You stated that eyestrain is a myth, therefore that there doesn't exist even one person in the world who experiences it.
2. I said I am such person (there are many more, even in this thread), and that's enough to show it's not a myth.
3. I don't dispute that your eyes don't feel strained when reading on LCD. However, that doesn't mean that everybody is the same as you, and that what works for you, works for everybody. Your opinion that it's a myth would require everyone not to be strained when reading from LCD, and that's clearly not the case.
(by the way, I'm a programmer as well. C/C++/asm/game programming. Nevermind.)

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.

If I answered everyone in the thread, and everyone answered me, it would quickly become impossible to say anything, as the number of information would increase exponentially. Also, while there are users who piss me off on the forums, your posts rather amused me, at least up to now.

That's exactly what I'm doing on LCD. I wrote about this... apparently you didn't read it

A computer screen will do more or less the same, since even though it is bigger, it is further away. So if you are reading in a dark room, your eyes will adjust mostly to the environment, trying to get as much light as possible. Beside the size of the FOV, there is also the matter of receptor density, which can also differ from person to person, making it possible for some eyes to adjust more to the light going to the center of the FOV.
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.

Thank you for the explanation. That would be quite enough to explain the example I gave, and it wasn't a good one to illustrate my problem. Please consider this: when I read on iPhone screen in darkness, I get headaches. However, if I turn on the lamp, I can then read for much longer time on the same screen, in the same conditions, and not get a headache. That's the same as with LCD screens, that's why I wrote in my first post that I'm always making sure the screen is brightly lit by outside source when I work. However, I should think that with such additional bright light, the amount of light entering my eyes would be even greater - so why am I not getting headaches then?
I thought for a long time that the problem was the refresh rate of the monitor. CRT monitors actually flash quickly, ie. get bright when raster line passes through pixels, and then get drak until next frame. I noticed that it took longer for me to get a headache on a CRT monitor with higher refresh rate, and I thought that possibly, with additional external source of light which doesn't blink/flash, the relative amplitude of minimal lighting vs maximal lighting isn't so big, and that's why my eayes don't get strained as much.
But then, as far as I know, LCD monitors don't blink/flash/get light/dark (what would be the right word?) 60 times a second, and yet I still get headaches, and still lighting a monitor with additional lamp helps me avoid them.
