f.lux

f.lux is a simple tool that helps your computer screen adapt to the time of day—warm at night and like sunlight during the day. Designed to reduce eye strain and improve sleep, f.lux automatically adjusts your screen's color temperature based on your location and wake/sleep schedule. The idea is that just like the sun changes color throughout the day, your screen should too. It’s great for people who spend long hours in front of a screen, especially in the evening. By minimizing blue light exposure at night, f.lux can help support natural sleep rhythms, reduce digital eye fatigue, and create a more comfortable viewing experience overall. You can customize its behavior to match your preferences, whether you're working late, watching a movie, or pulling an all-nighter. Key Features: • Automatic color temperature adjustment based on time of day • Location-aware settings that follow the natural light cycle • Night mode to help reduce blue light exposure • Highly customizable—set transition speed, temperature, and more • Movie mode that preserves screen color for viewing content • Experimental features like darkroom and color effects • Runs in the background with minimal system impact • Supports multi-monitor setups and wide hardware compatibility f.lux quietly does its job in the background so you can focus more comfortably—day or night.
