The most commonly asked question about the 20-20-20 rule is: "Do I need to switch back to [normalized] every time I shift focus, for a break?"
The answer is: whatever you wish. However, it would make your life easier if you kept the [[focal plane]] you are already using, be it [differentials] or nothing depending on where you are in your journey, for breaks under 5 minutes. If you are taking a much recommended longer break; this is a good time to switch to normalized, in order to ensure you are not trading close up strain for excessive blur strain.

The 20-20-20 rule is designed to be an easy to remember caution about doing too much near work and to give your eyes a break from eye strain regularly. This rule is supported by conventional optometry[1][2] and is a start towards the EM method.

  • Every 20 minutes
  • Look at something 20 feet away (6 meters)
  • For at least 20 Seconds

Endmyopia recommends even more breaks.

  • Every 20 minutes, take a 5 minute break.[3]
  • Every 3 hours, take the longest break you can (half hour to hour) [4]
  • Take your break outside. [5]
  • As you develop Strain Awareness you can customize your break schedule to your needs.
