f.lux - Adjusts your computer's display to adapt to the time of day

Long time user here & love the app & its soothing effect. Though I couldn't really find information on the wave length and frequency of the light emitting from the screens and the the difference created. ie, AFIK light of around 390 nm wave length seems to activate the serotonin switch (of the serotonin - melatonin pathway) & thus reduces prevents melatonin production (Eyes > Ganglion cells > optical nerves SCN > Pineal Gland). Do f.lux and similar products merely increase light in the high wave length parts (low frequency) so that for the visible eye its soothing ? Any pointers to analysis with say lightmeters/frequencies / comparison of frequencies etc ? Just curious.

A great tool. Really helps, and definitely recommend.

It may take some getting used to, but if you are working post 5pm, this is the only way to go.

@rrhoover no idea how it live without it.... @liveink me tooo but i figured there were some noobs here ;)

Used this and loved this for years. I've yet to use it on my phone, but certainly a must for all day at the monitor.

My eyes will thank f.lux forever. Last one year had been so strain-less for them. :)

One of the first apps I install on every new mac. Love the movie and darkroom effects as well!

How I love this app 😊

First started using it two or three years ago through an article in https://www.lifehack.bg/.

Pros:

It's so good that I forgot I was using it. I have never turned it off since. :) Try it!

Cons:

Maybe when doing design work, it could interfere with the perception of colour, but I have tried it while photoshoping, and it's no problem.

This product is a must have. Tim Ferriss first turned me onto it. I will say that if you are using it and gaming or anything visually demanding... Remember to turn it off to check designs. If you are gaming or watching a movie. It will cause your screen and graphics card to stutter as nightfall hits.
