f.lux author here, still slogging through the article. It is hard to understand the light levels used because they use "power" (uW, mW) from a laser, and not "irradiance" (uW/cm^2 or mW/cm^2), so which area they have concentrated that light over is hard to understand. All I can see is it is from a laser, so the irradiance could be extremely high. The human lens filters most light at the peak of the given spectrum for…

Thank you for your input, but I mostly want to thank you for f.lux. It has been one of my favorite things for a long time. It's silly how long it's taken companies to provide a native blue light filter and your product just kicks ass. If you guys ever wanted to figure out your app on a smart TV (or apple TV), I know there'd be a lot of thankful people! Also, I'd love to contribute to the ongoing dev of f.lux (I don't…

On the AppleTV go to Settings > General > Accessibility > Display Accommodations > Light Sensitivity.

Then you can assign it to the Accessibility Shortcut and turn it on or off by triple pressing the Menu button.

Now I’m wondering about the damage of all those Windows crashes and blue screens :-) Seriously though, the sky is blue, the sea is blue, how come we’ve evolved into beings affected by blue light??

This is affecting people in their 50s+, a lot of our evolution people had and raised offspring before this occurred so there was no evolutionary pressure to keep your vision much past that. It was good enough.

I have the "blue light filter" on by default, on my android mobile. Don't know how effective it is, but it will at least help a bit.

On my Google Pixel, this is under Settings > Display > Night Light.

In Android Pie, it's also one of the 9 shortcuts you get when you pull down from the top twice on your home screen, right next to airplane mode.

This or something connected to it is literally ruining my last chance at life but I cannot solve it and there is always a catch. I was disabled long ago by bad surgery and left in lots of pain. My physical career was ended. I was denied social assistance and fell in every crack. Life has never been stable enough long enough to reeducate and rebuild. In suicidal desperation I posted in a few places asking for ideas. A…

> reduce their quality of life further by using one of the 2 expensive and limited E-Ink displays out there

Could you elaborate on above? I did not understand the logic behind the sentence. E-Ink displays by themselves do not generate any light as they don't have any backlight or light emitter behind the display. That's why they work in bright sunlight. Some products with E-Ink displays have frontlights for night time reading. Is that what you are referring to? If so, given this article, just turning off the frontlight and using non-blue light sources for lighting is sufficient to avoid this, right?

This is a huge problem. Neon light everywhere. I go out at night with sunglasses. The world is littered with light polluting salvages. That and combustion engines. I used to drive one. I used to behave criminally too. Light, sound, air pollution are real crimes. The world is littered with criminal brutes; anyone who uses bright neons, churns a combustion engine, or plays the stereo loudly. Soon the little people will be angry at the 'rich bastards who burn gas with their machines or waste power on overly bright aggressive lights'. Average person will then only afford a handful of KWh per month, and my life will be better. I wont stop any crowd from hanging gas/naphta burners or smashing neons tubes.

I was recently diagnosed with a condition called retinitis pigmentosa (it basically just destroys your retinas). It's part of a larger condition called usher syndrome (which caused my severe hearing loss at birth). I'm on heavy doses of vitamin a palmitate as well as some other vitamins. Another thing that I haven't done yet but will be doing shortly is blue light blocking glasses, especially since I sit in front of…

My wife's brother has retinitis pigmentosa. He's 64 and has been blind for years. You definitely have my sympathies.

I don't have any advice except to learn Braille, which I'm sure is not very encouraging. I hope a cure is found soon.
