The Vitamin Deficiency behind TIRED and STRAINED EYES
For mini breaks, we recommend the 20-20-20 rule: Every 20 minutes, look away from your screen and focus on an object 20 feet away for 20 seconds. This gives the tiny muscles in your eye the chance to relax for a moment.
For longer breaks, we recommend you get up and stretch your legs, neck and back. While you do this, try closing your eyes to give them a bit of rest.
