When do children start to see?
It is known that the human eye begins to form on the 18th day of embryonic development. The eyeball is formed by the seventh month, and by birth, the visual receptors already feel light. So the moment when children begin to see comes before birth.
However, the vision of the newborn is far from perfect and very different from how an adult sees it.
- For the first three weeks, the newborn sees only blurred spots of light.
- In the fourth week of life, the child is able to discern silhouettes and follow the gaze of moving objects at a distance of about 30 cm.
- In the seventh week, a child can distinguish between flat and volumetric, and convex and concave objects differ at ten weeks of age.
- A three-month child sees almost as an adult and is able to distinguish between faces, and only in the fifth month a person begins to distinguish between the primary colors.
