Thank you Cyparagon for answering my question. I do promise that I'm absolutely serious. I realize that the members of this forum suppose that I'm a troll but I do promise you that I'm asking you seriousley. I have read about how LCD display, lasers, visual light spectrum, color space, e.t.c. work but I'm not an expert as I suppuose that several members of this forum is. Please do have patience with me.
Now I'll try to answer your questions.
"1) What makes you think a computer monitor emits light in the 190nm range?"
I should have explained myself in a better way. I really don't think my computer monitor emits light in the UV spectrum. I do think my LCD monitor emits light in the visual spectrum with a tilt towards the blue light in the 450-495 nm. I bought the Eagle Pair laser safety goggles called EP-1-10 because the 450-495 nm is within the 190-540 nm range.
" 2) What definition are you using that lists 190nm as blue?"
I don't think that 190 nm is blue light. I know that 190 nm isn't in the visual spectrum and I do know that LCD monitors doesn't emit UV light (I have actually red that the LED panel in the LCD monitors do emit very little UV but that the UV light never affect the computer user because it's blocked inside the monitor).
"3) What definition are you using that lists 540nm as blue?"
540 nm isn't blue. It is within the green wavelengths. I bought the Eagle Pair laser safety goggles called EP-1-10 because they Protect within the range 190-540 nm and because the blue light is within that range (450-495 nm).
"4) Why are you trying to block (what you've erroneously called) blue?"
I try to block the blue light of my computer LCD monitor because I do suffer from really severe sleeping problems and because the blue light has got the most energy of all colors (wavelengths) in the visual light spectrum. I have tried computer goggles that is told to block blue light but they really don't work. There are several test on the Internet that prove that those goggles only block a small amount of blue light that it really doesn't matter if one got severe problems. I've also tried the computer software f.lux and Iris but they don't work either. The only thing that has been working so far is the Dasung Paperlike e-ink display. The display is very expensive though and it won't protect my eyes against the light of all the computer displays that is almost everywhere in the society nowadays. Therefore I got thinking of laser safety goggles. I thought laser safety goggles would filter out the blue light so that my eyes only will be hit by light of wavelengths larger than blue. And maybe they do but I'm curious why I still can see the blue colors on my computer display wearing the Eagle Pair EP-1-10 laser safety goggles.
"5) We perceive light on a logarithmic scale. Full sun is upwards of 200,000 lux. If we block 99.999% of that, we have 2 lux. But 2 lux is still brighter than moonlight. This raises the following question:
6) How much blockage is acceptable?"
7) How have you determined the figure in 6 above?"
I don't know how much blockage is acceptable but I do want to block as much blue light as possible. I want to block 100 % if it were possible. The Eagle Pair EP-1-10 has an OD value of 5 so I do think that they would block 99,999 % of the blue light. My answer to question 7 is that I don't really know the figure but I know that I do want to block as much as possible.
"8) What makes you think modern monitors have three "light diodes"?"
The liquid crystal display in LCD monitors do not produce light by themselves they need illumination (ambient light or a special light source) to produce a visible image. This is done either by a panel of LEDs or by fluorescent "lamps". The liquid crystal display is between the light panel and the computer user. The LCD display have pixels that are divided into red, green and blue (RGB) sub-pixels. The liquid crystal display block (by polarizing the light from the LEDs in the light panel behind it) so that different amount of light will go through the red, green and blue sub-pixels. It really doesn't matter if the monitor does have three light diodes (red, green and blue) or if it does have single LEDs that emits blue, green and red light. The matter is that the artificial light from LEDs is created by a method called the additive method that combines red, green and blue to achieve the "white" light. Therefore the LCD display will emit light of blue wavelengths especially if the operating system shows blue colors I think.
"9) What wavelength do YOU think green is, since this is evidently purely subjective."
I do think that the 520–565 nm is green wavelengths. I can't see how it matters if the green light would be in 500-545 nm, 550-594 nm or any other range because I'm trying to block out the blue light. It would be great to block out the green wavelengths too but I'm mostly interested in blocking the blue light because it has the most energy.
" 10) What makes you think this phenomenon is exclusive to the windows operating system?"
The phenomenon isn't exclusive to the Windows operating system at all. If it were then I should have solved my problems long ago by changing to OSX or Linux. I did mention Windows as that is what I'm using right now but I'm really sure that the operating system is not the matter in this case. I've tried a lot of things to solve my severe sleeping problems and I have found out that I sleep well by using a Dasung display together with avoiding modern computer and smartphone displays. I must stay at home all day to avoid modern computer and smartphone displays and I want to find a solution that gives me the opportunity to expose myself to all displays in the society.
" 11) Have you considered altering... I don't know... the
display settings instead?"
Yes. I have tried using the "warm" setting of the display and I've tried using computer software as Iris and f.lux. They are worthless to me.
" 12) Are you aware that a blue photon generated from an LED is IDENTICAL to that of a blue photon generated from any other light source, including candles, incandescent lamps, fluorescent lamps, and the sun?"
Yes I'm aware of that. The difference is that the "white" light of LEDs is tilted to the blue light. There are more blue light in the "white" LEDs than in the "white" light of the sun. The LEDs do also flicker though is is said that the flickering of modern LEDs isn't detectable by the human eye. The light of the LEDs is also affecting us in an unnaturally way during the day because we are affected by the light of LEDs when it should be darker according to our "biological clock" while the sun and our daily sleeping do match. The "light polution" in modern societies is increasing. No doubt about that. I cannot turn off the LEDs in the society in the evening so I do need to find a solution so that I could spend time outside in the evening too. And I do want to have the possibility to use LCD display and not only my e-ink display.
"13) Are you a flat-earther as well?"
No I'm absolutely not. I know that the earth is approximately spherical although it is not perfectly round as some people do believe.
"14) If not, can I have some of what you're smoking?"
If you do help me solve my severe sleeping problems by helping me find a solution to block the blue light of modern computer displays then you will have the recipe.
Honestly I don't even smoke cigarettes and I promise you that I'm not trolling this forum. I'm trying to find a solution to my severe sleeping problems and I have come to the conclusion that there is something in modern computer displays that affects me badly. I do think it has to do with the flickering or the light, especially the blue light, of LEDs.
