Much like they learn to walk and talk, children learn to see over a period of time. Babies are not born with all the visual abilities they need in life – the ability to focus, move their eyes accurately, and use them together must be learned.
It takes several months for a child’s vision to fully develop. During that time, he or she will gain visual acuity (focus), learn to recognize faces and objects, develop depth and color perception, and become increasingly sensitive to light (as the pupils grow). But…
A child does not know what he or she is supposed to see.
That is why it is important to take an active role in a child’s vision development. Mobiles hanging over the crib, the stack of colored rings, the shaper sorter – and smiling faces – all play hugely important roles in your child’s eyesight.
It’s also important that, as early as 6 months – earlier if there are indications something may not be right – that children get regular eye exams with an optometrist.
