Eye Breaks Needed vs Screen Hours per Day
The 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds.
Breaks Needed = Screen Hours x 60 / Break Interval
This simple rule significantly reduces digital eye strain by allowing your focusing muscles to relax and your blink rate to normalize.
