For an 18-month-old, avoid screen time except brief video chatting; if you choose any media, keep it rare, high-quality, and watched together.

For a 15-year-old, set flexible recreational screen limits around 1–2 hours a day and protect sleep, school, exercise, and real-world time.

There’s no single hourly cap for screen time; match daily use to age, purpose, sleep, and activity, and build in breaks and device-off hours.

Most physical therapist assistant programs take about two years of full-time college after high school, plus licensure steps in your state.

For a 14-year-old, set a custom plan: keep recreation near 2–4 hours, protect sleep, and anchor each day with 60 minutes of real-world activity.

For 1-year-olds, aim for zero daily screen time; brief video chatting and short, co-viewed, high-quality clips are the only exceptions.

For eye comfort, match screen brightness to room light, keep contrast clear, and cut glare; auto-brightness gives a solid baseline.

For most adults, keep recreational phone screen time under 2 hours a day, with frequent breaks and a 60-minute screen buffer before sleep.

For teenagers, there isn’t one “right” number—balance screen time with 8–10 hours of sleep, 60 minutes of activity, learning, and screen-free times.
