If you want to activate the application now, check the Turn On Tone Now option. Also, to start the application when you start the computer, check the Start at Login option. It's recommended to schedule the app to be active during night time. If you start at login and schedule the app, you can forget it exists, just enjoy the benefits.

If you scheduled the dimmer to activate during the night, but it's not starting, just make sure you set the from hour behore the to hour (for example start at 22 o'clock in the evening and stop at 7:30 o'clock in the morning). Also, the app can be scheduled during the day only (for example between 10 AM and 10 PM).

The monitor's blue light tricks our circadian rhythm (our natural body clock) into thinking that it's daytime. It suppresses melatonin (that sends "time to sleep" cues) and builds up histamine that helps wake us up, boosts attention and reaction times. In other words, it resets that feeling of tiredness and hurts our sleep cycle. Just remember: It's bad to be exposed to sleep-inhibiting blue light during the night.
