    This is open source, while f.lux wants you to download a binary and run it constantly on your system.

    Very minimalistic and lightweight. Doesn't affect games (i.e. microstuttering) the way f.lux does (if you set it to Paused mode).

    Eye Saver eliminates flickering too not only filters the blue light as Flux does plus breaks timers and screen color effects. Great software.
