Newborns can only see blurry shapes because they are very nearsighted. At birth, a newborn’s vision is between 20/200 and 20/400. Your baby’s best vision is about 8 to 12 inches away. That means that if they could read, they would be able to read the big "E" on an eye chart.  By 4 months of age, acuity has improved to 20/60 vision. By 8 months of age, the nervous system has matured enough to improve acuity to 20/30, and is now nearly as good as normal adult acuity (20/20). Over the next several years, acuity improves gradually to adult levels; As babies grow, vision improves Your baby's color vision is also developing, so brightly colored books or toys will help develop this ability to distinguish color and form. Soft pastel colors, though, are difficult for a baby to appreciate. Therefore, infants reflexively prefer to look at high-contrast edges and patterns. Large black and white patterns present the highest possible contrast (100%) to the eye and thus are the most visible and attractive to babies
