Ok, thanks for the explanation!

Blue light and UV are different - LED-backlit monitors do not produce any UV.

We design f.lux to work with daily rhythms, so if you have normal vision, you need some blue light during the day, and much less at night.

@paulschreiber this issue has been there since forever. Reported on it way back. Unfortunately, it's still present.

@mathwizurd Update: turns out it was Google Chrome which was resetting Flux.

I went full screen, clicked on the Flux icon, and saw it was "Disabled for Chrome." I unselected that, and everything worked!

@helloworld234 I'm not sure if this is the bug that's turning Flux, but it seems to have gone away and not come back. I have floaters in my eyes that makes reading tiring and difficult when the screen is bright compared to my office environment, and Flux was a big help until it stopped working. My problem is that Flux has vanished from the bar at top and I can't get it restarted. Any suggestions would be welcome.
Thanks

thanks, that helps me. It was not checked initially, but when I try "Disable->for an hour" it shows me a hidden check-box "Disable->for iphoneSimulator". When I uncheck both - all works as expected.

🤩 🥳

Assuming you're in the same place at night, I would just dial back the f.lux settings until things look good.

FWIW: personally I do not enable True Tone because I think it is too warm during the day.

Also, I can't find a place to post forum bugs but when I went to enable email notifications it wouldn't let me save due to pagination settings that I assume were the defaults as I did not set them: https://i.ibb.co/KhYBKWF/Screen-Shot-2021-11-09-at-18-14-50.png

Hmm, looks like they are 5 hours behind (or really, 19 hours ahead). But you are right, the language settings should have no impact on local time. I will email for some more debugging.

Thanks - mine is macOS 11.5.2 with Chrome 93, so slightly different, so maybe the Chrome 94 beta is changing some things?

Not exactly related but suggests something is changing:
