f.lux for Mac

f.lux is a piece of software for Mac OS X, Windows, Linux, and Android operating systems that allows users to control the amount of blue light their computer screens emit throughout the day. Whether you use your computer during the day or at night, it controls blue light to lessen the effects it has on our bodies.

A Clever Solution to a Big Problem

For those unfamiliar with the concept, blue light from computer screens mimics sunlight in such a way that our bodies can’t tell the difference between the two. Since sunlight helps our bodies determine when to go to sleep and when to wake up, being exposed to constant blue light never allows our brains to fully shut down at night. f.lux provides a solution by cutting out the amount of blue light emitted from computer screens, in turn helping users sleep better at night and wake up refreshed in the morning. Especially useful for those who work late, it can lessen the burden of a bright, unsightly display.
