How does a child’s vision develop?

Birth: Vision is blurry (5% of adult vision) and in black & white. Newborn babies mostly see high-contrast objects up close and their field of vision is still very limited.

2-3 months old: Babies can fix their gaze, follow their mother’s face then objects. They respond to smiles and perceive differences in colours.

3-9 months old: The 2 eyes learn to work together, which enables the baby to see in 3 dimensions (3D). They start to notice details.

1 year old: Vision is still blurred, estimated at 30-40% of adult vision. Coordination between the child’s eyes and hands improves.

4 years old:   The retina is fully developed, but vision is still only about 60%.

7 years old: The vision corresponds to that of an adult (100%), but its “fine” development is still on-going.

How to choose children’s glasses?

Children have the “world” in front of them, but also above them: they look up to see you, for example, and what’s more, they move much more than an adult!

Three elements are essential:

  1. Large glasses so that the child can always see through them, even if they are looking upwards
  2. Good support behind the ears
  3. Good support on the nose so that the glasses do not slip

Beware of the sun!

The lens of the eye, the crystalline lens, is transparent up to 9 years of age and does not protect the eye from direct sunlight. Children should therefore wear sunglasses whenever they are exposed to sunlight, for example at the seaside or in the mountains.
