Step by step
Matched by age, one source at a time. Bodies do not agree on what “screen time” even counts — some include every screen, some exclude schoolwork, some cover only recreational use. Averaging them would produce a recommendation nobody actually issued.
What this number cannot tell you
No single country’s guidance is applied to every child, and no myopia risk is calculated from hours used — that needs findings from cohort studies, not a table of durations.
Common questions
- Why is there no number?
- There is no figure here that can be given with confidence, so none is given. The normal range for questions like this is wide anyway — a few minutes with a paediatrician or dentist usually settles it.
- What if my child’s age or country is not covered?
- It will say plainly that this age is not covered, rather than borrow figures from another age or another country. How far a standard reaches is set by whoever published it, and stretching it gives a placing that is simply wrong.
