G.lux: Free Display Adjustment Programs

Free open source program to adjust computer display for reduced eye strain and improved sleep, adjusting screen color temperature by lighting conditions and time of day.

What is G.lux?

G.lux is a free, open source program that adjusts a computer's display color temperature to match lighting conditions and the time of day. This helps reduce eye strain and improve sleep.

During the day, G.lux adjusts the screen to be bluer, matching daylight colors. At night, it shifts the display to be warmer and reduce blue light exposure. Blue light at night can negatively impact sleep cycles and quality.

By automatically adapting screen color rather than using a static setting, G.lux aims to provide improved eye comfort while using a digital display. The warm nighttime colors help avoid overexposure to blue light that might otherwise disrupt natural melatonin production and make it more difficult to fall asleep.

As an open source program, G.lux is freely available and allows user customization of color temperature settings for their preferences. It works automatically in the background once enabled, continually adjusting the screen throughout the day.

Overall, G.lux is designed for those who use screens at night and want an easy way to reduce eyestrain and potentially improve sleep quality without manually changing display settings.
