How to do it

  1. Hold your thumb up at arm’s length, a little below eye level.
  2. Look at your thumbnail for a few seconds.
  3. Now look past it at something far away, about 20 feet or more, for a few seconds.
  4. Switch slowly between the two, blinking as you go.

How long

Five slow changes of focus, about 30 seconds.

What you should feel

Your eyes adjusting focus each time. It should not feel strained.

Stop if…

  • Eye pain, double vision, a sudden change in vision, flashes or floaters: see an eye doctor promptly.
  • Headache or dizziness during the exercise.

Variations

  • Without the thumb. Use the edge of your monitor as the near point and a window as the far point.

Common mistakes

  • Rushing the changes.
  • Forgetting to blink.

Use it in a routine

The stretch routine builder can play this with other eyes stretches, with a countdown for each side and a chime at every change. The stretch break timer adds stretches like it to a break after each work interval, and the 20-20-20 timer reminds you every 20 minutes.
