Children's Eye Exams: When to Start and What to Expect

Vision is the sense that feeds the most information to the brain during learning. Yet many vision problems in children go undetected for years because kids don't know they "can't see well" — they simply assume everyone sees the same way they do. A timely eye exam can be the difference between a child who learns easily and one who struggles without knowing why.

At Òptica Florit we see many families who bring their children in with vision problems no one had picked up before. In this article we explain when to book the first exam, what warning signs to watch for, and what the process involves.


When should the first eye exam take place?

Newborn – 6 months

Basic paediatric check

The paediatrician checks the pupil reflex and that the eyes move correctly. No optician visit is needed at this stage, but extra attention is warranted if there is a family history of strabismus or amblyopia.

Age 3

First complete exam at the optician

At 3, a full objective exam is already possible. Myopia, hyperopia, astigmatism, and possible amblyopia ("lazy eye") can all be detected. This is the most important milestone exam.

Before starting school (ages 5–6)

Pre-school exam

Essential before year one. Uncorrected vision problems are one of the most common causes of learning difficulties. Many children labelled "distracted" simply can't see the board.

Every 1–2 years

Follow-up exams

If vision is normal, every two years is enough. If the child wears glasses or there are risk factors (myopic parents, heavy screen use), annual exams are recommended.

⚠️ Important: School vision screening only picks up basic visual acuity problems. It does not detect convergence issues, accommodation problems, or amblyopia. It is not a substitute for a full professional eye exam.

Signs your child may have a vision problem

📚

Holds books or screens very close

Classic sign of myopia. The child moves closer to compensate for blurriness at distance.

👁️

Squints to see

Another sign of myopia. Squinting reduces the pupil aperture and temporarily improves focus.

🏫

Can't see the board from the back of the class

May complain openly or silently copy from classmates — often going unnoticed by teachers.

🤕

Frequent headaches when studying

Sustained effort to focus at near distances can cause frontal headaches and eye fatigue.

📖

Struggles to read or skips lines

May indicate convergence or eye-movement issues — not necessarily dyslexia.

😵

A turned eye (strabismus)

If the eyes are misaligned, the brain may "switch off" one to avoid double vision. Needs urgent attention.

🏃

Clumsiness or difficulty judging distances

Binocular vision problems affect depth perception and can make a child appear clumsy in sport.

💤

Tires quickly when reading or studying

Visual fatigue after a short reading session can signal uncorrected hyperopia or accommodation problems.

💡 Key fact: Amblyopia ("lazy eye") affects 2–3% of children and can only be treated effectively before the ages of 8–10. After that window the therapeutic opportunity closes. Early detection is therefore critical.

What happens during a child's eye exam?

Test What it detects Child's cooperation needed?
Retinoscopy / Autorefractor Myopia, hyperopia, astigmatism No — the optometrist measures directly
Cover test Latent or manifest strabismus Minimal — just needs to look at a target
Visual acuity test Sharpness of vision at various distances Yes — pictures or letters depending on age
Binocular vision test Coordination between the two eyes Minimal
Fundus exam (if indicated) Retina and optic nerve health No — dilating drops used if necessary

Common myths about children's vision

  • "If they see fine at a distance, they don't need an exam"

    Hyperopia, astigmatism, binocular problems, and amblyopia can all exist alongside good distance acuity.

    ✓ Reality: A complete eye exam detects far more than basic visual acuity.
  • "Glasses make your eyes worse"

    Glasses do not worsen vision. Myopia progresses due to genetic and environmental factors, not wearing correction.

    ✓ Reality: Not correcting vision does not slow progression and can worsen amblyopia.
  • "They're too young for glasses"

    There is no minimum age for glasses. If a 2-year-old needs correction, the sooner the better.

    ✓ Reality: Glasses designed specifically for babies and toddlers are safe and comfortable.
  • "The school already checks their eyes"

    School screening only catches severe acuity problems and has a high false-negative rate.

    ✓ Reality: School screening is complementary to — not a replacement for — a professional exam.

Myopia control in children: what you need to know in 2026

Treatment Description Effectiveness
Orthokeratology (Ortho-K) Rigid gas-permeable overnight lenses that temporarily reshape the cornea High — 40–60% reduction in progression
Myopia-control contact lenses Soft lenses with a special optical design (e.g. MiSight, Mylo) High — 50–60% reduction
Myopia-control spectacles Lenses with peripheral optical technology (e.g. Stellest, MiyoSmart) Medium-high — up to 60% reduction in some studies
Low-dose atropine Eye drops prescribed by an ophthalmologist at very low concentrations Variable — effective but requires medical follow-up
💡 Tip: Time spent outdoors (at least 90 minutes per day) reduces the risk of developing myopia. Natural light is the most studied and accessible protective factor.

Frequently asked questions

At what age can a child start wearing contact lenses?
Generally from the ages of 10–12, when the child is mature enough to manage hygiene responsibly. In special cases it may be recommended earlier. The optometrist makes the call based on the child's maturity and motivation.
Do video games and screens cause myopia?
Not directly, but prolonged time indoors staring at close-up screens is associated with myopia progression. The protective mechanism of outdoor time is the bright natural light.
What happens if amblyopia is not treated in time?
Untreated amblyopia can cause permanent vision loss in the affected eye. The critical treatment window is before ages 8–10, while the visual system is still plastic. After that, visual recovery becomes much more limited.
How long does a child's eye exam take?
A complete exam in young children (ages 3–6) takes 30–45 minutes. If cycloplegic drops are needed, an additional 30–45 minutes must be allowed for them to take effect.
Is myopia hereditary?
Yes, there is a significant genetic component. If both parents are myopic, the child's risk is considerably higher. Lifestyle factors (outdoor time, screen use) also play a role. With a family history, more frequent check-ups are advisable.
