​20-20-20 Rule for Eye Health: This Simple Rule Can Prevent Eye Strain by Donna John

Have you heard of the 20-20-20 rule when it comes to straining your eyes with computer, tablet and phone screens? To rest your eyes, it's good to look up from your work every 20 minutes, focus on an object 20 feet away for 20 seconds – the 20-20-20 rule. 

Lighthouse Guild, the leading not-for-profit vision and health-care organization, says this type of eye strain – also known as computer vision syndrome – doesn't permanently damage eyesight, but symptoms could include:

• burning eyes
• tired eyes
• headaches
• neck pain
• fatigue
• blurred 
• double vision
