Very useful
I tend to stay on my mac way too late at night. The light definitely wakes me up (when I should be growing tired) I noticed a drastic difference within just a few minutes of turning on this app. The best thing is to be away from a screen at night but if one insists on sitting in front of a screen then do so by Candlelight.
