## 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.
### Additional Tips
- Blink frequently (we blink 66% less when staring at screens)
- Adjust screen brightness to match surroundings
- Position screen 20-26 inches from eyes

Exemplo Resolvido
8 hours of screen time with 20-minute intervals.
- Breaks = 8 x 60 / 20 = 24 breaks
- Total break time = 24 x 20 seconds = 480 sec = 8 min
- That is just 8 minutes of breaks across 8 hours
