Blue Light Screen Filter

Lol, this was interesting.  Love it when he goes off on the acrylic monitor shield.

Blue light?
I'm guessing that most don't realize that CRTs
generated soft Xrays... way more dangerous than
blue light

For going blind?

[Bizman]

Vraciu, calm down. I just saw an article about monitors and eyesight. It said that watching a monitor too much won't make you blind but it will make your eyes dry and cause nearsightedness.

There's a whole lot of misinformation in the world today, for a big part because of the Internet. For example there's a hoax running that Finland doesn't exist, the area here is just a sea between Sweden and Russia where Japanese fishing fleet are harvesting seafood to be transported by train through Siberia to the Far East. Oh, actually that's true. In reality I'm not the naked guy lying on a blanket on a frozen beach, I'm a blue whale.

Just had to edit your post so I can get busy sharing it.

The data suggests otherwise.  In a couple decades we will find out for sure. 

No good can come of bombarding your eyes with blue light.    If my doc says so I believe him.  He has been dialed into this stuff for decades and knows his stuff. 

So my original question remains.   Are there any effective blue light shields for monitors or is it a scam?

[Bizman]

Oh, I'm not saying that blue light wasn't harmful, my last comment was for your reaction to the X-rays.

As for blue light, adjusting your monitor colour temperature will work as good as the filters. If you have lots of blue light sources around you, then filtering glasses are the way to go.

Are the filters scam or not? Well, if they work they aren't but IMO it's like having so many lamps on that you'd have to wear sunglasses inside.

[Vraciu]

I had so many x-rays as a kid that the point is moot.  They didn't realize they were bad for you and I wound up landing on my head regularly.  That explains a few things, eh?   

If settings adjustment works I will be glad for that.   Still prefer something to put in front of the screen. 

If f-lux would stay enabled while playing AH that would be a start.

[Bizman]

You really don't want to adjust the color temperature in the On Screen Display of your monitor , do you? Or doesn't your monitor feature the settings? Mine doesn't in spite/because of having been quite expensive at the time.

Now that people have grown aware of the negative side effects of too much blue light, companies like f-lux see some marketing potential. F-lux says it's free, but they have the donate button for those who'd like to support their work. If every tenth user sends five bucks, the programmers will get well paid for.

Since you know how your monitor looks like with f-lux enabled, you might try the built in color calibration tool in Windows for the same effect. This tutorial tells how to do it in Windows 10: http://www.windowscentral.com/how-calibrate-your-pcs-monitor-windows-10. I suppose the same works for Win 8/8.1, too. In Win 7 it's in the side panel Control Panel/Monitor, or you can use the search bar in the Start menu for "calibrate color". The application itself is the same in all versions. #14 in the tutorial is where you can reduce the amount of blue as much as you wish. And those settings will stay until you change them.

I can try it. 

The one thing I like about f-lux is I can turn it off for short periods when working on skins.   A permanent monitor adjustment will screw that up.

Also, if I have a filter I KNOW is blocking the stuff then I have faith in it empirically.   The stuff isn't getting through.   Monitor adjustments don't give me the same confidence.   It's a matter of seeing is believing I guess.

[Bizman]

A matter of seeing is believing indeed.

How much do you remember of the color studies back in school? I mean colours and complementary colours? Yellow is the opposite of blue in the RGB system used for coloured lights, and since you can't stretch the imaginary pole between the opposites, adding yellow will reduce blue. Logically, reducing blue will add yellow. So what you see is what you get.

If you're worried about materials, i.e. glass vs. plastic, just think about the cheap cardboard 3D glasses with the thin plastic film lenses (anaglyph 3D). If that kind of material can block half of the information off, I'd call that sufficient by a margin. A yellow overhead film on your screen would cut the corresponding blue entirely. The intensity of yellow determines how much blue will be cut off. You can test that by looking at a blue sky image through a flat bottle containing some yellow liquid. Dilute that with water to see the green sky turn bluer by every drop.

Even blue light is just light, subject to the laws of colours and optics and electromagnetic radiation. There's no magic involved. Again, what you see is what you get.

I just figure that if you overpower the blue with something else you're still getting the blue--you're just getting more of the rest, too. 

Good info all around.   My thanks.

Now to find my white whale--a screen filter I can believe in. 

[Bizman]

Umm... No.

If you try to overpower the blue with yellow, the blue has to give way. That's the law. The only thing you can get "more" is brightness and speaking of monitors there's a dedicated setting for it. A set level of brightness doesn't change, only the proportions of different colours do.

Think about a jar full of liquid. Liquids don't give up, you can't compress them. If you want to add something into the jar, something else has to come out. Adding yellow liquid to a jar full of blue liquid will make the blue liquid flow over the rim. The amount of blue will diminish. The more yellow you add the less blue you can have in the jar - or in your monitor. No matter how saturated the colours are, adding one will deduct the counterpart.

Believe your eyes. What you see is what you get.

Fair enough, man.   Thanks for the reassurance.   I tend to be too skeptical sometimes.

Is adjusting my monitor going to reduce the non-visible stuff also?
