Screen time, sleep and balance — Cyber safety for kids
Screens are great for learning and fun, but your eyes, body and sleep need balance. Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Switch screens off well before bed and charge your phone outside the bedroom, because bright screens and exciting games keep your brain awake. Agree on a gaming time with your family, keep meals screen-free and play outside every day.
20-20-20 and lights out — “rest your eyes often and switch screens off before sleep”
20-20-20: every 20 minutes of screen work, look 20 feet away for 20 seconds.
Screens off before bed (often an hour before); phone charges outside the bedroom.
Agree on a daily limit with your family and keep track: minutes left = limit − minutes used.
Use it for: Homework on a laptop, online classes, gaming, videos and phones at night.
Worked example: 👀 The 20-20-20 rule: every 20 minutes of screen work, look 20 feet away for 20 seconds. Ishaan studies on a laptop for 60 minutes. How many eye breaks is that? → 3
One break every 20 minutes: 60 ÷ 20.
60 ÷ 20 = 3 eye breaks.
Check: Try it: for one week, switch screens off at a fixed time before bed and note how you sleep ✓
