What is the 20-20-20 Rule?

This short article will define what the 20-20-20 rule is, why it is beneficial to implement into our lifestyles, and a recommendation to begin using it effectively in schedules.

The 20-20-20 rule is every 20 minutes, take 20 seconds to look away from an electronic screen to see another object 20 feet in your vicinity (1). Why is the 20-20-20 rule useful? A recent study published by Statista, stated 63 percent of people or approximately 5 billion people use the internet every day (2). On average, people spend more than eight hours a day (3) using technology, which is problematic, since this can lead to digital eye strain and eventually cause the following symptoms (4):

  • Eye pain

  • Dry eyes

  • Worse vision

  • Fatigue

  • Headaches

  • Back pain, if you do not maintain good posture for the whole day

By implementing the 20-20-20 rule into our work schedules, people can ease eyes from preventing continuous strain when it is needed to use technology for long periods. If a person is sitting in one place for a while using technology, it is recommended to get up and stretch. Doing daily stretching exercises improves body posture by slowly strengthening the body’s muscles (5). To implement this into a daily schedule, set an alarm or a reminder to use these tips. To ease eye pain, follow these suggestions:

  • Use the 20-20-20 rule

  • Blink more often to prevent constantly staring at a screen

  • If needed, look away from the screen and close your eyes for 20 seconds to a minute to ease eye strain

  • Sleep seven to eight hours a day to rest your eyes

  • Do stretching exercises to improve body posture

  • Use artificial tear eye drops or artificial tear eye ointment for dry eyes

  • Try to minimize screen time when possible

If the problem worsens, make an appointment to visit an Ophthalmologist or an eye doctor.
