    F.lux on my iMac running Mountain Lion is perfect. The seamless transition from daylight to evening + vice versa makes those subtle changes in the screen + menu bar colour which all but eliminates eye strain. Just set F.lux to start at login, enter your location, make any other Preference changes from the F.lux icon in the menu bar, then F.lux takes charge. When I use my iMac in the evening, I can then fall asleep very comfortably.
