Color temperature adjustment utility for PC
F.lux is a free utility tool for PC made by developer Michael Herf. With it, users will be able to adjust the color temperature of their computer screen displays. It's specifically beneficial in helping relieve eye strain for people who often work during the evening.
Similar to CareUEyes or ScreenTemperature, F.lux helps users reduce the amount of blue light that their displays emit when using them at night. Blue light is a specific type of light that adds to eye fatigue. It is also considered to be a factor that contributes to sleeping disorders, such as insomnia.
How does it work?
If you spend a lot of time on your computer, you're sure to have experienced eye strain at one point or another. Many factors contribute to this, but one of the most common is blue light, a part of the light spectrum that your screen emits. Its effects are more apparent during the evening as it can also affect your sleep patterns and can amplify certain sleep disorders like insomnia.
It's for these health reasons that programs that help control blue light emission have been developed, and F.lux is one great example. It's a handy utility that lets you adjust the color temperature of your screens depending on the time of day. It can automatically adjust your display output using your geolocation data, seamlessly cycling between warm light at night and sunlight during the day.
Alternatively, you can input your own custom settings and color adjustment in F.lux to suit your needs. Use the slider to change the screen temperature to your liking, and set a schedule when you want it to take effect. One thing to consider, though, is that using this utility won't be ideal if you deal with color-sensitive work where accuracy and correct reproduction are essential.
Save your eyes
Overall, F.lux is pretty much a must-have for any modern-day PC user that spends a considerable amount of time staring at their screen throughout the day. It helps relieve eye strain, promotes better sleep cycles, and the program itself is intuitive and customizable. Using it is one of the best things you could do for your eyes. Highly recommended.
