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

After using this for sometime, I can barely look at other screens now. Must-have for night-owls
Dan Friedman
Works great! Always easier to work at night.

Flux is one of my favorite finds on Product Hunt so far. I love the moment my screen dims at ~5:30pm. So relaxing.

@rrhoover game changer

@rrhoover May I also suggest you also Iris :) https://www.producthunt.com/posts/iris-96099dd8-2a53-4a39-a83f-072074ec7d0c I also included 1000 free activation codes in the comments. Some things you may like is the ability to lower the brightness also automatically based on the time of the day. And customizing day start and end times via the clock. You can also customize the transition duration for the effect. I really like the easy to use interface of ProductHunt. Great work :)

@daniel_georgiev nice!

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.

It helps to understand the science. Blue lights suppress melatonin, which keeps you from going to sleep when you want to. This is why staring at screens before bed = no good. F.lux works by filtering out blue light. You get a red hue to your screen which takes getting used to, but it seriously makes it easier to go to bed if you're using your computer late at night. There's a similar Android app as well, that I highly recommend. Game changer.

@sethporges Yes, I would also add that blue light is the highest-energy visible light and in the long run may cause age-related macular degeneration.

My eyes will thank f.lux forever. Last one year had been so strain-less for them. :)
Nir Golan
One of the first apps I install on every new mac. Love the movie and darkroom effects as well!
Miles Matthias
This is the best app I've installed on my mac to date. Highly recommended.

@WalkOffTheEarth just did an excellent promo for Flux on Meerkat
Stefanos Kofopoulos
Cool app. Apple Watch is solving this problem much better IMHO
Adriaan
YES

I've been using f.lux for so long, it's hard for me to imagine life without it.

I work on my computer for hours in the evenings, and this has been a life-changer in order to fall asleep at night. @herf, I feel like I owe you. This product ROCKS. 🙌

Just remember to disable it if you're doing design work with color. 😅
 

Ever notice how people texting at night have that eerie blue glow?

Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?

During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.

f.lux

f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

 

f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.
