f.lux is a cross-platform computer program that adjusts a display's color temperature according to your location and time of day. It aims to reduce eye strain during night-time use by gradually removing blue light from the screen, making the display warmer as evening approaches.
Why It’s Useful
By automatically adapting your screen's color to the time, f.lux helps to minimize digital eye strain and promotes better sleep patterns. It creates a more comfortable viewing experience, especially when working late into the evening, by reducing the disruptive effects of blue light on melatonin production.
