Children rarely complain about poor vision, mostly because they don't know their vision is anything other than normal. That's what makes routine screening so important — many conditions that are easy to correct at age four become much harder to treat by age ten, simply because the visual system has already finished developing around the problem.
When to schedule the first check-up
We generally recommend an initial vision screening between ages three and four, even if nothing seems wrong. This is early enough to catch conditions like amblyopia ("lazy eye") while the brain-eye connection is still developing and highly responsive to treatment.
Signs parents often miss
- Sitting unusually close to the TV or holding books very near the face
- One eye drifting inward or outward, especially when tired
- Frequent squinting or tilting the head to see better
- Rubbing eyes often, or complaining of headaches after reading
- Avoiding activities that need close focus, like colouring or puzzles
- Poor hand-eye coordination for their age
Any one of these on its own isn't necessarily cause for alarm, but a pattern of them — or a teacher mentioning similar concerns — is a good reason to book a screening rather than wait for the next scheduled check-up.
Squint (strabismus)
A squint, where the eyes don't align in the same direction, is one of the more visible conditions and is generally easier for parents to notice. Left untreated, the brain can start to ignore input from the misaligned eye, which is how a squint can lead to permanent reduced vision in that eye if it isn't addressed early.
Myopia (nearsightedness) in children
Childhood myopia has become increasingly common, and tends to progress steadily through the school years without intervention. Regular monitoring allows for myopia control strategies — including specific corrective lenses and outdoor time recommendations — that can meaningfully slow how quickly a child's prescription increases over time.
A child who sees clearly out of one eye often won't complain — because as far as they know, that's just what "seeing" looks like.
What a pediatric eye exam involves
Exams are kept short, calm and age-appropriate, typically covering visual acuity (using picture charts for younger children), a check for squint or misalignment, and a look at overall eye health. Nothing about the process should be uncomfortable, and most children are done well before they've had time to grow restless.
