F.lux Software to Adjust Electronics’ Blue Light Emissions
Free software f.lux makes a computer, tablet, or smart phone display adapt to the time of day-warming at night and like sunlight during the day. With numerous reports of the blue light from electronics creating an alerting effect and thereby interfering with circadian rhythms when used during evening hours, f.lux could be one solution to improve consumers’ sleep.
Users tell f.lux what kind of lighting they have, and where they live. Then f.lux does the rest, automatically.
