"Black and white toys are an excellent way to engage, interact and bond with your baby in the early days. The high contrast stimulates their vision and provides a target of interest to enable exploration and 'play' at a very young age."

“When we are born, despite the fact that our eyes start to develop early in the womb from week 4 of pregnancy, infants have very poor sight and limited colour vision. They will gaze into the mid distance and often the eyes will not coordinate well together. Over the initial few weeks of life infants will only be able to see items that are distinguishable by a distinct contrast in colour, the optimum combination being black and white. When presented with such a target the baby’s visual pathway will be stimulated and the brain can work towards matching the images seen by each eye, in turn teaching the eyes to coordinate with one another. The more the eyes learn to coordinate, the more accurate the eye movements become and by default the more detail the eye and brain can detect, thus providing a continuous feedback and improvement system. Infants will start to detect colours a couple of months later starting with red and they will be able to see the full spectrum of colours by 5 months of age.”
