While you might think the net result is the same, the table above highlights that there are some important differences to be aware of. When you wear blue light blocking glasses you are exposed to less high-energy visible blue light - from both your screen and external sources. Instead of changing the color emitted by your screen, blue light blocking glasses filter the amount of blue light that actually reaches your eyes. What are blue light blocking glasses?īlue light blocking glasses also reduce the amount of blue light you are exposed to - but in a different way. If you’ve ever seen a colleague or someone with a particularly yellow-looking screen display, they may have been using f.lux. ![]() Using f.lux means your screen will change color. Or keep a steady setting to your preference (you can even try it out without installing it here). You can set the program to mimic natural sunrise and sunset cycles. ![]() Warmer colors are lower energy and typically feel easier on your eyes.į.lux allows you to adjust the color temperature of your display to reduce the amount of blue light (the big blue spike in the diagram above) emitted by your monitor. The diagram below shows the default color temperature profile for a Macbook Air device:Ĭooler colors are high-energy and are typically harsher on our eyes. You are simultaneously exposed to ‘cooler’ colors such as blues and greens, as well as ‘warmer’ colors such as reds and oranges. ![]() Whenever we look at our monitors, we are exposed to the full spectrum of light wavelengths it is emitting. So what’s color temperature? And why would you want to adjust it? It provides an in situ, real time, species specific, nonintrusive probe with a geometry compatible with conventional MBE growth chambers. Moreover, if you need to have the monitor display images in their original hues and tones when working on a graphical project for instance, you can easily disable f.lux.F.lux is a computer program that adjusts your monitor’s color temperature to reduce the amount of blue light you are exposed to.Īpple’s Night Shift also allows you to change the color temperature of your screen, but it is less intense than f.lux. The present invention provides a photoionization mass spectroscopy flux monitor for gaseous species above a sample surface. It adjusts the screen light and colors to match the ambient light, sparing your eyes from making an effort to watch the monitor. Getting blinded by an overly-bright monitor during sunset or later at night is definitely not pleasant so an application such as f.lux is useful to anyone. Make the screen light and tones match your surroundings For instance, the “Movie Mode” preserves the colors and the shadow details but still displays the entire screen in warmer color tones that balances powerful contrasts. There are also predefined configuration modes in f.lux. f.lux comes with predefined configurations for reducing eyestrain, working late at night, using the PC in a low-light environment, and more. On the other hand, you have the possibility to adjust the screen lighting and colors manually, which is convenient in case you are in an environment with special lighting conditions. Therefore, if you find that you are not satisfied with the settings, you can go back and make more adjustments. ![]() It is worth mentioning that f.lux enables you to preview an entire day’s lighting changes in just a few seconds. Automatically adjusts the screen brightness and tone In 2020, MSI announced the PRO MP242 series of 'eye care monitors', with 'low blue light and flicker-free technology'. It then renders the appropriate light tones and intensity depending on this schedule. In other words, once your position is set on the map, the application calculates the precise time of the day and puts your PC on a 24-hour transition schedule. The main perk of f.lux is that once set up, it can automatically adjust the screen's brightness and color to the night or day conditions, without your intervention.Īt first launch, it requires you to enter your current location (the nearest city will do) to determine your local time and get information about the lighting conditions, depending on the time of the sunset and the sunrise. Sets a daily schedule based on your real location There are solutions such as protective glasses, but a more convenient alternative is using a dedicated software utility such as f.lux. The screen’s brightness and the blue light particularly, puts a strain on your eyes, especially if you are using the PC during nighttime. Working long hours in front of the computer has negative effects on your eyesight.
