cooldudz I guess the answer to your question is mere stubbornness =p
I don't want a workaround solution. I don't want my screen to look like yellowed newspaper. I don't want to have to wear funny glasses just to see a screen. I want to be able to look at all these screens everyone else gets to without issues. Maybe unrealistic expectations? Maybe, maybe not.
Take the curious case of the user jasonpicard here. They are the only user that described my issue basically perfectly. They suffered these symptoms for over a decade like I did, but they seemed to have it even worse than I did. They had to wear these dark orange SCT glasses just to use any monitor. I bought a pair. They are so aggressive that a pure yellow square on a white background will be completely camouflaged because the white background is as yellow as the square is. Does it cut down my symptoms on an LED? Sure does, but at a cost.
The user above hasn't posted for years because they solved their issue and likely went on with their life. They purchased a ViewSonic XG270 monitor, and they mentioned that they can use the monitor 16 hours a day if they wanted to without issues, and without the dark orange SCT glasses above. Looking at the specs of this monitor, it makes 0 sense why this monitor is working so amazingly well for them. Perhaps the dark orange SCT glasses were a red herring all along for all we know, and blue light was only part of the answer. All I can tell you from what I have read is that the ones that had the most success did so by pure trial-and-error, trying the most amount of monitors they could, until one worked. When they found the one that worked, they did not know why it worked, and frankly did not care.
I can just go running back to my Dell U2410 CCFL monitor at any time, which I have done so many countless times already, and have done so again. I know this monitor will not last forever, nor will other CCFL monitors, and that's why I'm still in research mode. Also, CCFL monitors do use PWM to dim their displays, which I think may contribute to a bit of the eye ache I will get on it with enough reading and usage. Basically the CCFL "hurts different". The strain feels more like traditional reading overuse eyestrain rather than this bizarre migraine-like neurological queasiness I get with LED-backlit displays.
So the answer to your question is: yes, the blue blocking stuff works, but I'm still annoyed by the "side effects" of not looking at proper colors, lol. I can still display pure whites on my CCFL monitor and it will look white to me as long as the brightness is at 0%. This could be because CCFLs have a different color spectrum which spikes more in the green section rather than the blue, and I believe our eyes/brain take the average of the spectrum.
Your case is interesting, but one I have heard about many times before actually! Some get a lot of strain from looking at saturated reds. Some had trouble on quantum dot QD-OLED monitors because of how red those reds were on that! Prior LEDs seemed to have pretty dull looking reds. You probably counter-intuitively would do better from switching your monitor settings to "cool", or trying to adjust the RGB values to give more preference to "B" and less to "R".
Another thing you could due is use green-tinted glasses, which should block red. MigraLens is one example. I've heard a lot of podcasts from multiple sources where migraine-sufferers gain the most relief by looking through a green filter. Perhaps a walk through nature such as a forest would be quite therapeutic for you!
Sounds like we have the same issue with the same cause (color sensitivity), but on polar opposite sides of the color spectrum!
