f.lux – Better Lighting… For Your Computer

Just have found f.lux – a Windows, Mac, Linux, and iPhone/iPad software that automatically changes your computer screen colors and brightness based on the time of day. To make long story short, there seems to be some evidence now that LCD/LED displays are too bright in the evening/night, and this is causing sleep difficulties (eyes and thus brain are treating this bright light as a sun light, so they refuse to sleep). Will try it definitely.
