New to Children's Vision? Start Here
Children's Vision: the few things that matter most, and the mistakes that catch people out early.
Detecting and correcting sight problems while the visual system is still developing.
Key takeaways
- Vision screening: offered around age 4 to 5 in England
- Free NHS sight tests: for all children under 16
- Most useful single change: Take up school vision screening.
- Commonest mistake: Waiting for a child to complain about their vision.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Why bother
Amblyopia is treatable in early childhood and largely untreatable later, which makes the timing of detection decisive.
Start here
Start with two. Add the rest once those have stopped taking effort.
- Take up school vision screening
- Book a test if you notice squinting, head tilting or sitting very close to screens
Then add these
After that, these.
- Have children tested even without complaints; they rarely report poor vision
- Mention any family history of squint or lazy eye

When to speak to a doctor
Seek urgent assessment for a white reflection in the pupil in photographs instead of red-eye, a new squint, an eye that turns constantly, or any sudden vision change — a white pupil reflex can indicate retinoblastoma and needs same-day referral. Also seek urgent help for a painful red eye or eye injury.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
