Action point


Normally, humans blink about 18 times a minute, but studies show we blink half that often while using computers and other digital screen devices, whether for work or play.

That contributes to eye strain, and your general feeling of tiredness, especially at the end of the day.

What to do?

  • Post a note that says “Blink!” on the computer as a reminder.
  • Every 20 minutes, shift your eyes to look at an object at least 20 feet away, for at least 20 seconds: the “20-20-20” rule. 20 Feet is about 6 metres.
  • Use tired or sore eyes as a signal that it’s time to stop working and get some rest.
