The child’s vision: evolution and explanations

A child’s vision changes over time, passing through different key stages. From birth, an infant has blurred vision and limited visual acuity.

However, as a child grows, their visual system develops and becomes more accurate.

How exactly is this vision evolving? Keep reading to find out!

The child's vision:

how does the infant see ?

A baby’s vision changes dramatically during the first few years of life.


From birth, a newborn sees the world blurry and in black and white. Their visual abilities develop gradually over the months, depending on the maturation of their ocular and brain structures.


Initially, the baby’s retina is not yet fully formed, which limits their visual acuity. However, as the retina continues to mature, vision improves and the baby begins to distinguish shapes and colors in their environment.


Around the age of 6 months, binocular vision develops, allowing the baby to merge the images of their two eyes and to have a three-dimensional perception of their environment.

La vision de l’enfant :

the first years of life

During the first years of life, most children develop normal visual acuity, allowing them to distinguish small details and see clearly up close and far away.


However, some children may have visual problems such as myopia, astigmatism or hyperopia. These refractive defects can cause blurred vision and require optical correction such as wearing glasses or contact lenses.


It is crucial to detect these visual abnormalities at an early age, as they can affect a child’s development and lead to learning problems if left untreated.


A regular eye exam with an ophthalmologist or orthoptist will help detect any visual defects and correct them quickly.

If a visual disorder is detected in a baby, appropriate treatment can be put in place, whether it involves optical correction with:



It is essential to act quickly to prevent any further complications and ensure good vision for the child.

The development of a child's vision

A child’s visual system continues to develop until around age seven.

During this period, adequate visual stimulation is essential to promote the maturation of nerve connections and ensure good binocular vision. However, if certain visual problems are not detected and corrected early, it can lead to permanent vision problems.

It is therefore essential to monitor the child’s vision from an early age, by making regular visits to an ophthalmologist or orthoptist.

Our COP9 vision health professionals are trained to screen for and treat childhood vision disorders, and will recommend more in-depth examinations if necessary, such as visual field tests, refraction measurements or retinal exams.

The child's vision:

possible pathologies

A child’s vision is also closely linked to the health of their eyes.


Eye pathologies can affect a child’s vision, such as:



These conditions require prompt medical intervention and can lead to severe vision loss or even blindness if left untreated.

Additionally, eye disorders such as strabismus or amblyopia can also affect a child’s vision. 


Early detection of these visual abnormalities is essential to effectively manage any possible pathology.

The child’s vision and family history

It is important to note that the child’s vision can also be influenced by other factors such as a family history of eye disorders, systemic pathologies such as diabetes or hypertension, or lifestyle habits such as overexposure to screens.

It is therefore essential to take all these aspects into account to ensure the child’s good visual health.

In conclusion

The child’s vision evolves over time, passing through different key stages, under the influence of multiple anatomical and neurological factors. It is essential to quickly detect and correct any visual defect or eye disorder in order to promote optimal visual development.

Regular checkups with an ophthalmologist or orthoptist, as well as attention to risk factors, will help ensure good vision throughout the child’s life.
