Screen Time Impact Calculator
Assess the health impact of your daily screen time and get recommendations for healthier habits.
The 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds. Excessive screen time is linked to digital eye strain, disrupted sleep (blue light suppresses melatonin), poor posture, and reduced physical activity. The American Academy of Pediatrics recommends no more than 1-2 hours of recreational screen time for children.
