Digital devices are part of modern life — but they can leave eyes tired and dry. This guide to the 20-20-20 rule offers practical, eye-friendly steps.
Why Screens Strain Our Eyes
Long screen sessions reduce how often we blink and expose eyes to glare and blue light, which can leave them dry and tired. Understanding the 20-20-20 rule helps you counter that.
Practical Steps
The 20-20-20 rule, better lighting, screen distance and regular breaks all ease the 20-20-20 rule. Small adjustments to your setup add up quickly.
