Hi,
Thank you for sharing this it is really interesting.

@herf I agree and disagree. It makes sense to have a small white patch to see. However most apps I use have darkmode, which makes the "right color choice" the one fitting darkmode-apps :)

@VitaAurum777 this is in our very-beta root-only build for Android, but it is not really maintained for current devices.

@karahbit yes we have been saying this since a few years before Iris existed, though it sounds like our marketing isn't as good!

With a majority of LED backlights today showing essentially no flicker when they dim (see https://www.notebookcheck.net/PWM-Ranking-Notebooks-Smartphones-and-Tablets-with-PWM.163979.0.html), we don't think this is for everyone, as it has an impact on contrast and power usage. But with a display with bad flicker, it's absolutely a good way to do it.

@karahbit it is not an overlay - only our vignette mode does that.

@lux1782 I think screens should dim quite a bit before bed, but also the ambient light in the room you're in matters a lot as well. So I would try to have some scheduled dimming in your room, and then dim the screen to keep it readable, but not bright. The color changes we do with f.lux account for another 3-10x in "equivalent dimming" but you should do both.

@NinetyDruid5 if you post f.lux options > driver info sometimes we can help. This usually happens when one of your monitors is connected with an older USB adapter, but for certain kinds (DisplayLink) we can help get it working.

@tellner have you tried the "far from the equator" preset? Agree that you should be able to set some more parameters here too.

@Myriam modern phone held 5cm from eye will get to about 1000lux, but 10,000 lux needs a standalone lightbox.

Hey there,

I have a quick question regarding a topic that was brought up by the OP. The OP suggested certain functions for the f.lux program, and I'm curious to know if these functions will be included in future updates or if there are any community-driven solutions available.

If anyone has information regarding the development plans for f.lux or if there are any existing community solutions that address these functions, I would greatly appreciate your insights. It would be fantastic to know if there are any updates or alternative options to explore.

Thank you in advance for your time and assistance. I look forward to hearing from you.

Best regards,
Zoe

@Tungsten_smooth yes, in a directional light, lumens=lux at 1 meter. In a hue bulb (600lm) it's radiating in all directions so it is somewhat less. If you want 10,000 lux you would have to be very close or have a dozen or more bulbs at arm's length. Not easy to do with this form factor.

Hue v1 maxes out its melanopic content in the mid-4000K range because it employs the most "chips" and the illuminance is somewhat higher as a result.

The tubes are likely more directional and would probably be better. Many ad-hoc lightboxes were built like this. But also there are reasonable light therapy panels online for $50 that will make this amount of light to, though some of them have to be used very close to the eye as well.

Don't forget to diffuse the light - staring at any of these lights directly for 30m can be quite painful.

If something like that was available I'd probably go back to running f.lux and disable Nightshift.

I would also like to purchase from Amazon

@vanmaricor Not f.lux related--have you looked into hemp (minimal-buzz cannabis)? Seems to work wonders for many with seizures.

But it will release excessive heat also and make a burden on your pocket.

Hi @maxime - no we do not agree it is wrong. It's there for a reason, which is that your body is made up of clocks that entrain to light. That's all it says and it's true.

It would be wrong to say it's a psychological trick or a thing that only involves sleep or a little suggestion, it's actually pretty fundamental to our biology and we want more people to know about it.

Here is a paper that explains how half the proteins in the body are rhythmic based on when your eyes see light - the truth is that your body has billions of clocks, and they're everywher. In some ways, you can choose to have them work well or not, by giving them a strong day-night signal. This is the way immunity, digestion, repair are regulated by the body, and why timing of light is so important.

Thank you for the information. I've been working a lot on the computer lately and my eyes are getting tired, I wanted to try protection glasses. I will try this option.

@Barrydunn f.lux is still better than Night Light, but hey, you gotta do what you like the most right? That's what I'd do, so that's all I can recommend. F.lux or Night Light, whichever you like the most.
