How Does the 20-20-20 Rule Prevent Eye Strain?
These days, screen time is a major problem. You most likely spend a significant amount of time staring
at displays, whether they be on your smartphone, television, work or home computer, or other
digital gadgets. Overexposure to screens can cause eye strain. Still, the 20-20-20 rule could
be useful. It's possible that your eye doctor has brought up this guideline if you find yourself
