When Should a Child Have Their First Eye Examination?

The short answer is before school, ideally somewhere around three or four years of age, and earlier than that if there are risk factors or if anything has concerned you.

The longer answer is worth having, because the reasons behind that timing explain why waiting is a genuine risk rather than a minor delay.

Children do not report vision problems

This is the foundation of everything else, and it catches almost every parent.

A child has no basis for comparison. If the world has always looked the way it looks, there is nothing to notice and nothing to report. A child with markedly reduced vision in one eye will function normally, play normally, and say nothing, because the other eye is doing the work and they have never known anything different.

This means the absence of complaints tells you almost nothing.

The window that closes

The most important reason not to wait concerns amblyopia, commonly called lazy eye.

Amblyopia develops when one eye receives a poorer image than the other during early childhood, usually because of an eye turn, a large difference in prescription between the two eyes, or something obstructing vision. The brain progressively favours the better eye and the visual pathway from the weaker one fails to develop properly.

Treatment works well when it starts early. Effectiveness declines substantially as the child gets older, and by around seven or eight the opportunity to achieve a full result has largely passed. Beyond that point some improvement remains possible but the ceiling is lower.

The condition is entirely invisible to a parent. The eye looks normal, the child behaves normally, and the only way to detect it is to test each eye separately.

That single fact is the reason for examining preschool children who have no symptoms and no complaints.

Testing does not require reading

Parents frequently assume their child is too young because they cannot read a letter chart, or cannot yet describe what they see.

Neither is necessary. Vision in young children is assessed with picture charts, matching cards where the child points to a shape rather than naming it, and objective techniques that measure the eye's focus directly without requiring any response at all. A meaningful examination is possible well before school age and in children who say very little.

When to come earlier

Some children should be seen well before three.

Come promptly if there is any eye turn, even an intermittent one that only appears when the child is tired. Come if there is a persistent head tilt or turn, if one eye appears different from the other, if there is a white or unusual reflection in photographs, or if your child holds objects unusually close.

There are also risk factors that warrant earlier examination in the absence of any sign. A family history of squint, amblyopia, or a strong prescription in childhood raises the likelihood considerably. So does significant prematurity, and so does developmental delay.

If in doubt, bring them. An examination that finds nothing is a good outcome rather than a wasted appointment.

Why the school screening is not enough

School screenings are useful and they catch a proportion of problems, but they are designed narrowly.

They typically test distance acuity and little else. They do not assess near focusing, eye teaming or tracking, which are the functions that matter most for reading and classroom work. They occur after the amblyopia treatment window has substantially narrowed. And they are not diagnostic, so a pass is not a clean bill of health.

A pass answers one question. It leaves several others untouched.

How often afterwards

Every two years is reasonable for a child with no findings and no symptoms, and annually is preferable once they are at school, since prescriptions change fastest during the primary years.

If short sightedness has been identified, reviews should be more frequent, because progression is monitored over time rather than assessed at a single visit.

In Australia, optometric consultations attract a Medicare rebate. Whether an appointment is bulk billed varies between practices, so it is worth asking when you book.

Where to from here

The children who benefit most from an early examination are the ones showing no signs at all, which is precisely why so many are not brought in.

At Noranda Optometrist we examine preschool children routinely, using tests designed for their age rather than adapted from adult ones. If your child has not been examined and is approaching school age, that is worth booking rather than waiting for the screening.
