There’s a new f.lux for Mac today. Here’s what’s new: Dim on disable It’s always been painful to disable f.lux for a color check or late-night design work, so we’ve provided a new option that dims your screen (a lot) when you disable. Check out the “Options” menu for this feature.

Download f.lux for Windows to save your eyes by making your display's brightness adapt to the time of day. F.lux has had 0 updates within the past 6 months. F.lux warms up your screen at night to help you relax and wind down before bed. Created in 2008 to help screens look more like a book, f.lux is now informed by science in sleep and circadian biology to help you adjust your body's sense of night and day. Redshift adjusts the color temperature according to the position of the sun. F.lux is a small app that adapts your screen color to the amount of light in space you're in. F.lux uses both the type of light in the room you're in and the time of day as points of reference. You can select halogen, fluorescent, or natural light to get greater precision.

Do you have f.lux installed on your computer?

F.lux is a free blue light exposure protection app you can install on your desktop to filter out the blue light from your monitor. The app automatically shifts the color to a reddish amber as soon as the sun goes down.

Night Shift is another great blue light filter app option you can try out on your smartphone or tablet.

Blue light exposure problem solved! Right?

Not really…

Let’s find out the truth about the effectiveness of these blue light filter apps, and what you can do to solve this problem.

The problem with blue light filter apps

We all know the problem with blue light exposure is real. All the blue light from your devices is throwing off your circadian rhythms – a 24-hour internal clock that is running in the background of your brain and cycles between sleepiness and alertness at regular intervals.

Your circadian rhythm works best when you have regular sleep habits, like going to bed at night and waking up in the morning around the same times every day (including weekends).

When things get in the way, like jet lag, daylight savings time, or a compelling show on TV that keeps you up into the wee hours of the morning, you can disrupt your circadian rhythm.

This can be why you feel out of sorts and struggle to focus.

Additionally, lack of sleep can have other very serious health consequences. Research shows that sleep deprivation can increase the risk of these health problems:

• Anxiety
• High blood pressure
• Heart disease
• Diabetes
• Obesity

As for the blue light filter apps, they don’t work as a proper filter. Their lack of efficiency is due to the fact that they can only reduce the blue light instead of filtering or blocking it.

Why do we need proper filters to protect our eyes from blue light exposure?

Because ALL screens have this problem called backlight bleeding which means your monitor will still “bleed” light from the backlight and around the edges. That excess light isn’t picked up by f.lux, Night Shift or any other blue light apps as they are essentially offering a software solution to a hardware problem.

The problem with f.lux is it can’t eliminate but only reduce blue light exposure. Therefore, your eyes can still get strained when you use these blue light filtering apps.

Unfortunately, that’s not the only problem we’ve identified with blue light filter apps. Blue light is not only released by our smartphones and computers, but also by our TVs and all sources of artificial light. While these apps are certainly a step in the right direction, it definitely falls short to solve the problem completely. In fact, this study indicates that “less than 1 lux of monochromatic light elicited a significant suppression of nocturnal melatonin”.

To reevaluate your lighting strategies is no longer an option but a necessity to ensure maximum health. And this is what excited us the most. We needed a better blue light exposure solution, and thanks to Swanwick Sleep we have one.

Blue Light Exposure Eliminated!

At Swanwick Sleep, we believe sleep is crucial! And our mission is to help you achieve it. We don’t do things by halves. To prove it, we created our Swannies® Blue Light Blocking Glasses, our high quality sunglasses to not only filter but block all the blue light in your space.

You can wear your Swannies at night (at least one hour before going to sleep) to protect your eyes from all the blue light in LED emitting street lamps, while watching LED electronic screens, at baseball games, or anywhere blue light exposure can be an issue. There’s increasing scientific evidence that blue light may not just damage your sleep, but your eyes as well. The simple color shift provided by blue light filter apps is not enough to prevent such damage. If you’re already wearing glasses, it might as well be Swannies. That way you’re guaranteed healthy eyes and a good night’s sleep! Win-win!

Here are 10 tips to improve your sleep hygiene. When you sleep better you feel better, right?

That’s not to say your f.lux doesn’t offer any protection from blue light exposure. But if you’re wondering why you still haven’t achieved the peaceful sleep you’re dreaming about, Swannies just may be the answer for you.

Do you want full protection from blue light exposure?

F.lux, Night Shift, and other screen “filter” apps are not the solution to circadian disruption and poor sleep. Read on to learn why.

Light-emitting Devices

It seems that every week there are new studies and news articles about the dangers screen use at night. These screens that we’re staring into, emit large amounts of blue light. It turns out that light at the blue end of the spectrum is how our bodies track what time of day it is. Shining blue-rich light into our eyeballs at night is screwing with our body’s timekeeping mechanisms. And it’s not only making it harder for us to fall asleep. Circadian dis-regulation and chronic melatonin depletion have very serious health consequences. These are compounded by lack of quality sleep.

The standard advice is no screen-time an hour or two before bed. That’s great advice, but not practical for many people. Most articles now recommend installing blue “filtering” apps. F.lux is a very popular app for PC users. Android users can install Twilight. Apple now has Night Shift built in to their latest operating systems. Most people believe that is all they need to do. As you will see, this is not the case.

F.lux and other screen “filter” apps

F.lux is a free app that automatically shifts the color of your screen to a reddish amber color as the sun goes down. You set it to your time zone and the degree of color shift that you want and it does the rest. The idea is to match the color of your screen to the color of the ambient lighting. In the daytime your screen is in full color spectrum. As the evening wears on, the color shifts to amber/red over the course of an hour. Once you get used to the colors, most people love the app and won’t go without it. Of course people doing design work or other color sensitive work may not be able to use it. It can also take some getting use to. Most people start with a mild color setting at first. You can turn it further to the red as you become accustomed to it.

The newer version of the app can even sync with the Phillips Hue lighting system. That way your home lighting can shift in sync with your screen! I have not tried this feature yet but it seems pretty awesome.

So what’s the problem?

They are not nearly as effective as a proper filter

These apps do not “filter” anything. They reduce or (on the highest settings) cut out the color blue. The problem lies with the screens themselves. Screens are always emitting some degree of blue light due to bleed through from the back-light. You can’t fix a hardware problem with software. These apps are great but not nearly as effective as a true filter.

The silly-looking orange Uvex glasses are an actual filter that is far superior. With a little self experimentation, you can prove it to yourself.

These apps will reduce your blue light exposure and the stress on your eyes. They cannot eliminate it. There is a huge difference between reducing blue light and elimination it!

In fact, this study demonstrates that “less than 1 lux of monochromatic light elicited a significant suppression of nocturnal melatonin”! My advice is to go the extra step and block all blue light exposure as part of your evening routine.

F.lux Review

People tend to hold the screen closer to their eyes

Some of these apps reduce the screen brightness as well. The lower the back-light, the less blue will be emitted. This is great in theory. In real life, people tend to counteract the effect by holding the screen closer to their face.

If someone is holding the screen closer to their eyes, they are negating much of the benefits of using the app. The proximity to a light source make a huge difference in the biological response.

The “easy button” & the bigger problem

People are always looking of an easy “set it and forget it” solution. We tend to read an article that says “blue light at night = bad” then we can “just get f.lux” and go on with our lives. The problem is much greater than our electronic devices.

All energy efficient lighting, LED and florescent, emits strong blue light. Even the “soft white” color lamps have a sharp spike at the blue end of the spectrum. Joachim peiper trial by fel. These sources are becoming cheaper and more ubiquitous in our homes. Some government jurisdictions are banning the use and/or sale of incandescent lamps. Cash starved city government are highly motivated to “upgrade” street lights to LEDs. Despite overwhelming evidence of harm to the environment and public health, LEDs are taking over. Exterior lighting on homes and businesses is almost always blue rich LEDs. Even night lights are usually white LEDs that emit blue light all night long. We need to start structuring lighting environments that work with our physiology. Greater public awareness is desperately needed! I believe these apps are a step in the right direction. My concern is that filtering apps are like broom with which to sweep the problem under the bed and out of our sleep deprived minds.

Electronic Screens

At this point there are two main type of screens on our electronic devices: LCD and OLED. Most screens out there are some sort of LCD except for Samsung phones which use a variation of an OLED (AMOLED). LCD screens are back lit with either a white florescent or a white LED. Most computer screens are edge lit with a cold-cathode florescent tube on the top or bottom of the screen. A white diffusion panel that scatters the light uniformly across the screen.

Light Leakage

F.lux Forum

The main thing to realize about LCDs is that there is always some level of blue light passing through. No matter what color is on the screen. Theoretically OLED screens should have less of a problem with light leakage. The pixels are self-illuminating (no back-light). Therefore, filtering apps should be far more effective. I have seen a spectrograph of an iPhone (LCD) compared to Samsung (AMOLED). They are very similar, however they were measured with the screens displaying white. I would like to see spectrograph comparisons with the screens displaying all black.

Try this at home

You can see for yourself the blue light from your screen by doing the following test. If you go to BlueLightAtNight.com/black you will see a plain black page. Take your computer into a dark room and you can see how much blue light is coming out. If you shine it on a white wall, you will see that it is blue light. Play with the brightness levels. The light that you are seeing is from the white florescent or LED back light. Hides meaning. If you put a spectrometer on this, you will see the spike in the blue range which is typical of florescent tubes or LEDs. No matter what color is on your screen, this back-light is always shinning through even if you don’t see it.

So why do I use it (and recommend it)?

Flux Screen Dim

F.lux

Despite the fact that I spent the last 10 minutes of your time somewhat bashing f.lux, I still use it and recommend it. For one, it is better than nothing and it does help bring awareness to the problem. It does relieve eye strain. I like how it transitions in to nighttime mode as the sun goes down. It helps to keep me connected with nature in some small way even if I’m full absorbed into some computer project. Any reduction in blue light exposure is beneficial. But, if you want to optimize your health, I recommend using a proper pair of blue light blocking glasses.

F.lux For Mac

Oh, and did I mention that f.lux is free? Not only is it free, but the developers graciously provide tech support as well. They are nice people who are dedicated to helping others, and that’s something that we can all appreciate.

See the changelog.

November 19, 2019

v40.1 and earlier:

1. Bugs fixed for Catalina (and Mojave): dimming fixes, white cursor fixes, entitlements and notarization
2. Automatic updater fixes
3. Fixed map popup when you change timezones (now you can tell it’s f.lux)
4. Fixes for northern latitudes

August 20, 2015

There’s a new f.lux for Mac today. Here’s what’s new:

1. Dim on disable It’s always been painful to disable f.lux for a color check or late-night design work, so we’ve provided a new option that dims your screen (a lot) when you disable. Check out the “Options” menu for this feature.
2. Backwards alarm clock For years we’ve wanted an alarm clock that answers the question, “How much sleep will I get if I go to bed now?” So we made a little version of it for f.lux.
3. Better transitions If you woke up your laptop late in the day, f.lux used to do a very slow transition (as if you were “used to” the orange color). Now it transitions quickly to daylight instead. Also, we’ve tuned up behavior at night and in the morning for “bedtime” mode: the night-time and early morning transitions are longer now.
4. Expanded daytime settings For users who prefer very warm settings during the day, we’ve made an option that lets the sliders go all the way to 1900K, all the time. We prefer accurate color during the day, but quite a few people have asked for extra control like this. You can find this feature in the Options menu.
5. Less CPU We made improvements to the profile writer for dual-GPU macs. So this new version should have less impact on those systems especially.
6. Melanopic lux analysis A new screen analyzer in the About box. Visible easter egg?

Realtek 8187l driver windows 10. Quit old versions before running

October 25, 2014

There’s an update for Yosemite today.

March 12, 2014

We’re happy to announce a new update to f.lux for Mac today.

This new version has been in progress for a long time. We’re sort of nervous and excited about it, because we tried so many things before we figured it out.

f.lux now works with your actual schedule

1. f.lux adjusts to your actual day, not just sunrise and sunset.
2. It looks nice, showing you a visualization of your day.
3. There are tons of new effects and adjustments.

Your schedule

The new version of f.lux makes a schedule just for you, so you can use a screen that knows when you sleep, as well as when the sun’s up. We found a way to combine your day with sunrise and sunset. Here’s how it looks:

f.lux now shows you when the sun’s up and helps you wind down for sleep.

With the new f.lux, your screen warms up to make things look better at sunset. But then later, around the time you would start feeling sleepy, we do a little more, helping you get to bed on time. We’ve even tried to time this second phase with your body’s natural release of melatonin. You may find you want a more moderate effect at sunset now, because the bedtime setting can be more intense.

It’s really easy to set up, and it looks pretty good too.

What about the sun?

Usually, we try to make things visual and avoid using tons of numbers. But one number stood out so much that we had to put it up front.

How many hours of sunlight could you see with your current schedule?

A healthy circadian rhythm depends on seeing bright light while you’re awake, not just avoiding bright light before bed. Especially if you’re a night owl, this number is a super-interesting way to think about your day, and we hope it’s useful to you too.

Getting started

To have all this new stuff, all you do is tell f.lux when you wake up:

We suggest some default colors for people in different situations. (For instance, you can now use f.lux if you work the night shift, if you wake up at 3AM, or if you live in Oslo.)

If you need to do color-sensitive work, now you can run at full brightness until just before bed, and then f.lux will wind you down just in time to sleep. Ottplayer download for osx older versions.

There’s even a way to sleep in on weekends.

Setting up your day

As the day progresses, f.lux will move between its three light settings automatically. But because color perception depends on where you are, it’s kind of hard to predict how you’ll see colors at 11PM while sitting in your office at 1PM. We made this new interface so you can come back a few times (for a day or two) to set f.lux the way you like.

Improvements, Movies and Darkroom

1. There’s a Movie Mode to watch movies while preserving shadow detail, skintones, and sky colors. It lasts 2½ hours, longer than most feature films.
2. There’s a way to disable f.lux until sunrise.
3. There’s even a super-red mode we call Darkroom.
4. We’ve reworked all animations to make them smoother and cause less impact on your Mac.
5. Also added a way to disable f.lux by app. (The “working late” preset works ok for almost everyone, but this is some extra color-accuracy insurance.)
