f.lux

f.lux is a computer application designed to adjust the color temperature of a computer screen according to the time of day. The software works by reducing the amount of blue light emitted by a computer screen at night, which can help improve sleep quality and reduce eyestrain. By adapting to the user's location and the time of day, f.lux automatically adjusts the screen's color temperature to match the natural cycles of daylight. The program can be customized to suit individual preferences and varies in color temperature as the day progresses, creating a more natural and dimmed light environment for late-night computer work.
