Flux and the various other approaches are a fine way to re-grade the colors of a monitor to be more comfortable. By which I mean, if someone likes to use f.lux in the evening, they find the result more subjectively comfortable or pleasing, it's a great app.
I encourage people who are looking to solve sleep problems to not use any backlit screens in the several hours before sleeping. Such evidence as there is on the subject doesn't suggest that redshifting the screen is sufficient.
If you've seen someone using a laptop or phone in a dark room, it's quite clear that they're blasting themselves with a flashlight. Filtering some of the blue out isn't going to repair this basic dynamic.
- beaconstudios 5y agoI think the idea is that with a blue light filter on (and your brightness turned down) it's more like candlelight, which doesn't really disrupt sleep.
- TameAntelope 5y agoYeah, I’ve always found the assumption that f.lux actually redshifted the screen the same way their cited experiments did to be on shaky ground. I don’t recall seeing any studies that directly used f.lux, just studies with blue lightboxes, and that stuck out to me as odd. Monitors, even modern ones, don’t 100% convert their backlights (which are white) to the displayed color, so you always have an amount of washout, and I was always curious if that spoiled the effect, among other unique quirks of computer monitors.
