If you use Mac OS, Nocturne lets you darken the display, lower its color temperature, etc. manually/more flexibly than F.lux.
For Linux, there’s Redshift. I like it because it’s kinder on my eyes, though it doesn’t do anything for akrasia.
There is also Shades, which lets you set a tint color and which provides a slider so you can move gradually between standard and tinted mode.
