Knowledge is Power: What is a 20/20/20 Rule?

    The 20/20/20 Rule can be difficult to apply in the "real world".

    Jack’s Perks makes it easy with their online timer. No need to download anything.

    Simply go to and click "Begin Countdown".

    After 20 minutes, a message will appear, letting you know it’s time to look away from your monitor.
