The eyesight develops in the first 10 years of life.
Therefore, when the child is born, they’re not born with perfect vision. It takes a few months for the vision to mature and start to develop very well, and continues to develop throughout the first few years of life up to 10 years of life.
Now, if the vision is not developing in the way or at the speed it should develop, or if there is what we called prescription or refractive arrow, that means the child needs glasses to see. Then we encourage the parents to help us to get a child into glasses so they can develop good vision.
We need to remember that the development in vision is one aspect of child development. And in fact, the child needs to see well to allow other senses to develop and support the whole well-being of a child.
