(visit product page)

f.lux automatically adjusts the colour tone of the computer screen based on the time of day and this is setup in the program location settings.

When the sun is out f.lux will set the srceen tone to blue light (same wavelength as sunlight). Come nighttime after the sun has set f.lux changes the screen tone to warmer amber colours. This reduces blue light exposure to the eyes at night leading to better restorative sleep.

For Android devices use the Twilight app.
