f.lux solves this problem by adjusting the color of your computer's display to match the time of day, making it warm at night and bright during the daytime. 

It's possible that your computer is keeping you up too late. You could use f.lux to improve your sleep or simply to improve the appearance of your PC. 

Have you ever noticed how individuals texting at night have an odd blue glow? Or do you wake up ready to write down the next great idea only to be dazzled by your computer screen? 

During the day, computer screens seem wonderful because they are made to resemble the sun. However, around 9 p.m., 10 p.m., or 3 a.m., you should probably avoid looking at the sun. 

f.lux constantly changes the appearance of your computer screen to match the environment you're in. When the sun sets, your PC resembles your home lights. In the morning, it restores the appearance of sunlight. 

Tell Lux what sort of illumination you have and where you live. Then forget about it; flux will handle the rest automatically. 
 

Features

Customizable Settings: Users can tailor f.lux settings to their taste. This includes altering the transition speed between color temperatures, selecting a specific color temperature for day and night, and fine-tuning the effect's strength. 
Location-Based Settings: f.lux can detect your geographical location and alter its color temperature settings to correspond with sunrise and sunset times in your area. 
Presets and Profiles: Users can build and save presets or profiles for a variety of situations, such as working during the day, reading in the evening, or watching movies at night. This allows you to quickly switch between different settings depending on your hobbies. 
Disable for Specific Applications: Users can temporarily disable f.lux's color modifications for applications that require high color accuracy, such as picture or video editing software. 
Bedtime Mode: In addition to gradually diminishing blue light in the evening, f.lux includes a "Bedtime Mode" option that further minimizes blue light exposure closer to bedtime, perhaps improving sleep quality. 
Support for several Platforms: f.lux is available on a variety of platforms, including Windows, macOS, Linux, iOS, and Android, allowing users to reap the benefits across several devices.
