(f.lux author here): the initial part of this press cycle was effectively scare-mongering, and was later mostly retracted by Karunarathne. See https://www.theverge.com/2018/8/17/17724658/screen-time-blue... This (older) article says: "we don't spend that much time staring at the sun". But just seeing the blue sky gives your retina about 50x the dose of blue light (hazard) as a normal LED display. Blue light hazard is…

OT: I used flux ages ago. You seem still to be active since you intro'd yourself als the flux guy. Out of curiosity, why should anyone still use flux nowadays when all OSes have time-based red-shifting built-in?

I still find it better than the built-in night-shift on MacOS.

Just dropping by to say thank you for f.lux! I'm able to keep hacking at night because of it.

More accurately, you're able to stop hacking at night and thus have energy for hacking during the day.

A greater deal of blue filtering was available on f.lux last time I used it. Unfortunately since it did not allow for setting hours other than the local sunrise and sunset times, it wasn't useful to someone like me that suffers light exposure insomnia during the months with longer daylight hours. Even though my home has been setup to accommodate this, f.lux, at least last time I used it, would not. The built in feature in my OS happily lets me choose for myself when to filter blue instead of denying me that choice.

Personally - more options, more modes, more control.

Lots more information about this in Richard Feynman’s Color Vision lecture: http://www.feynmanlectures.caltech.edu/I_35.html

Wow, I just read the first section (four or five paragraphs) and learned two new things already. Is this representative of Feynman’s writings? The level of both clarity and information is impressive.

If you haven't yet read Feynman, you're in for a treat. It's not common at all to find someone with both great domain knowledge and great communication skills.
