At birth a baby’s eyesight is very limited; it is hard for them to focus, and their depth of vision is limited to about 30cm. Black and white images with sharp outlines are therefore much easier for baby to see in these first few months of life. Professor Usha Goswami, director of the Centre for Neuroscience in Education at Cambridge University, explains: “Anything with very obvious contrast – such as black and white edges and lines – is an optimal stimulant for the visual system,” she says. “This type of stimulation basically gets the system up and running”. A baby’s eyesight will continue to develop over the first 6 months – use of our specially designed black and white, and high-contrast books, will help to nurture that development.
