Blue Blocker Screens for TV's

    Can anyone recommend a blue blocker screen for TV's? I'm growing tired of watching the news with 2 pairs of glasses on! (My RX and then my Uvex).

    Lowbluelights.com used to sell one but they don't anymore....any ideas?

    Thank you!

    Rubicon mentioned something I believe in Mexico. He had it on his laptop if memory serves.

    Cool product. Is it a half-truth though, like f.lux?

    I think so, they target narrow range of blue in the 460-480nm range so green remains. According to this paper Effect of light wavelength on suppression and phase delay of the melatonin rhythm The shorter wavelengths of 470 (blue), 497 (blue/green), and 525 (green) nm showed the greatest melatonin suppression, 65% to 81%..so this implies that even with blue blockers you are getting some level of melatonin suppression with artificial light.

    Nice find.
    Sort of like flux.com but for TV.
    I noted there a sentence:
    "Removes blue signal from the red-green-blue signal according to desired intensity."

    That is there is still blue remaining, just of lower intensity.

    I assume that we do not need any blue at night.
    Actually green is also undesirable.

    I've tried a number of things for filtering blue light on displays. To test how well blue/green are being blocked, I open this image and visually check how much blue/green I can see: RGB.png

    Mobile phone screens
    I was telling Jack in Mexico about how good the blue blocking ability of Android phones are compared to iPhone because of apps like Twilight that make the screen really red. However, after recently testing with the RGB image I'm not sure if Twilight removes much blue after all.
    Screenshots: Before / After / Twilight Settings Used
    I would like to see exactly how the RGB image would appear on a Nightshifted iPhone.
    I may try a plastic blue blocking phone screen filter in the future to see how that compares.

    Rubylith Film
    I bought some custom sheets of Rubylith on Ebay that fit my computer monitors. They block all blue, and nearly all green.
    Before / After
    I think this would work on the TV if you could get a big sheet of rubylith, but I did not end up using this solution since I found a way to make f.lux do the same/better
    Another similar option I've seen but not tried is this amber UV filter film

    F.lux with customized setting for 900K color temp
    Normally the lowest color temperature you can select with f.lux is 1200K. At 1200K there's still a lot of green. @Rerun mentions here how to go into the registry on a windows computer and set f.lux at a color temp of 900K. At 900K, all blue and green disappears from the RGB image
    F.lux at 1200K
    F.lux at 900K
    I set my computer monitor to 900K if I use it in the evening, and on a laptop that connects to the TV in the living room for when I'm occasionally watching video.

    Getting f.lux adjusted to display at 900K as mentioned above is tricky. Recently a new app has was developed for blocking blue light called Iris (https://iristech.co/).
    They sell a "mini version" for $2 that has the ability to set the screen to zero blue with much less effort. If you don't mind paying two bucks per computer, I would recommend that at this time.

    Some images of my TV connected to a laptop set at 900K in F.lux / zero blue on Iris:

    Since returning home from the Optimal Resolution 2017 event in Mexico we've seen some big gains in our household that we attribute to aggressively blocking blue light at night with F.lux, minimizing screen time, and wearing blue-blocking glasses during the day while indoors under fluorescent/LED lights. Our n=2 experience would confirm that blue light really is perhaps the #1 most dangerous nnEMF

    Wow, thank you for this amazing information. I need to give these things a try

    lowbluelights told me that they stopped selling the larger filters that cover televisions because the optical quality of them was not very good. I think they said they still had some left, so you could try getting in touch with them directly to discuss.

    I went looking for a large screen protector bc, like you, I was uncomfortable with my rx plus uvex over but I never found anything that really blocked any significant blue. I expect most people will only tolerate a very mild tint on a filter (like blutech) and anything else is not going to sell to the mainstream market, so there isn't anyone doing those as far as I can tell.

    Night shift is worthless on iPhones but for some rI haven't seen anybody mentioning the new-er capability the iPhone has with iOS 10. Its called display accommodations and its better than twilight on my friends android and puts the jailbroke F.lux I used to have on my iPhone to shame.
    Settings--general--accessibility--display accommodations--color filters--turn color filters on--select color tint--drag intensity & hue bars all the way to the right.
    Using rubicons pics above I cannot see the red or the green. Occasionally this makes it really hard to see some things on the phone that are colored primarily blue/green but that can be fixed by turning on the gray scale which just adjust the relative colors of everything so its like looking at a black and white screen but dark red and light res instead.

    There is also a way to "reduce white point" and set a shortcut to activates the on command simply by pressing the home button 3 times

    This video shows us how we are being visually tricked by "Oz Behind the Curtain" and why we need blue-blockers and mitigation strategies against artificial lighting.

    Seizure Warning! I only watched a few sections of this video with my blue-blockers, shrunk down my web-browser to a very small view and listened (audio) to most of the video rather than viewing it. But it's a great resource to show what goes on in front of you!

    Great info, thanks!

    Is anyone using a blue-blocking filter for your computer monitor? I wear Ra Optics 450nm daytime yellow but I'd also like to filter my work computer during the day to protect my skin.

    I saw these:

    but they claim to block 100% up to about 540nm and are intended for evening use so probably not good during day job.

    I'm not allowed to download color tweaking software.

    Any ideas?
