3. Screen time management

You can prevent dry eye caused by digital eye strain by implementing the 20-20-20 rule. After every 20 minutes of screen time, look at something 20 feet away for 20 seconds. Every time we blink, a film coats our eyes and lessens dryness. Looking at something further away allows for natural blinking. You can also move your computer screen below eye level so you don't have to open your eyes as wide, which increases tear evaporation.
