f.lux

f.lux is a software application designed to adjust the color temperature of a computer display. It automatically adapts the screen's color to the time of day, making it warmer at night and like sunlight during the day. This aims to reduce eye strain and improve sleep patterns by minimizing exposure to blue light in the evening.

The software is intended for anyone who uses a computer, tablet, or smartphone, particularly those who spend extended periods in front of screens, especially after sunset. It operates in the background and can be customized with various color temperature settings and scheduling options.
