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 think I've had to pay for it?) How might I?

Huge thanks to the author from me as well!

Thanks for telling me :) Paypalling now

thanks for the link. I have been using flux for years and recommending it to my friends too.. just donated a small amount..

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.

Can't wait to do this tonight! This will help so much

Hook your TV up to a computer running f.lux or similar! I've used a HTPC for the past decade and more, wouldn't go back.

For my Samsung TV I use movie mode and also change colour temperature to warm.

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.

I just want to remind everyone that LED backlights emit blue light that isn't eliminated by f.lux or similar utilities.

Can you explain this more? If LED backlights emit multispectrum light (to get a white), and the LCD display filters those spectrum via RGB selection (say, letting less blue through, and more red/green), wouldn't this effectively filter the blue spectrum?

I know very little about this so I'm genuinely curious.

You might want to refer to our measurement project for some numbers:

Also, you can be below threshold for circadian responses just by being very dim.

Looking at your measurement, if I understand it correctly, you are saying that OP is incorrect and flux does in fact reduce the blue light?

So if a new macbook pro has:

"15.4-inch (diagonal) LED-backlit display with IPS technology; 2880-by-1800 native resolution at 220 pixels per inch with support for millions of colours"

What possible laptop alternatives are out there that are better for eyes?
