SunsetScreen enables you to take the glare off your screen during late night computer sessions. The program is designed to complement studies that have found that late night exposure of bright (bluish) light can interfere with your body's natural sleep preparation cycle.Inspired the popular F.lux application, SunsetScreen automatically reduces the brightness and color temperature of your screen at night, allowing for a less eye straining work environment.You can customize the color changes as well as the transition period and also change the default times for sunset and sunrise based on your local conditions or personal preference.
