SunsetScreen helps take the glare off your monitor in the evening. Scientific research has shown that melatonin - the chemical the brain makes late in the day - is reduced when exposed to blue light. By tempering this blue light, it becomes easier to wind down properly at night and thus, have a more restful sleep.Whether you're a morning lark or night owl, it allows you to set the time of the sunset and sunrise, so you can have full control over your sleep cycle.SunsetScreen Features: Set the sunset time precisely. Set the sunrise time too. Choose by color temperature or by HSB for a precise color. Transition from one phase to the other gradually. Automatically resides in the tray so it keeps out of your way. Loads automatically at Windows startup if you wish. Instantly turn off SunsetScreen if you need to do color sensitive work. Choose from a range of presets, and reset to default if things go wonky. Small, fast, elegant and easy to use interface in less than a megabyte.
