Infant Visual Development
Babies are born with visual systems that are still in the process of developing. Although human babies are born with eyes that are approximately 65% of the size of an adult’s eye, their visual systems are not nearly as developed. A newborn’s first views of the world are indistinct and hazy, but at even a few days old, studies show us that a baby prefers looking at its own mother’s face over the face of a stranger. The visual acuity of an infant allows him to see facial features at about 8-10”, which is about the distance from his mother’s arms to her face.
At one week of age, babies are able to see the colors red, orange, yellow, and green. It takes a bit longer for blue and violet. Babies are best aware of large high contrast shapes at this age. In the first month of life, the sensitivity of babies eyes to light is about 50x less than that of an adult. By three months of age, light sensitivity increases to only 10x less than that of an adult.When first born, a baby’s eyes are not yet coordinated enough to work together. Occasional wandering or crossed eyes can be normal in the first two months of life. True three-dimensional vision occurs around 4-5 months of age as the eyes become more finely coordinated. This can be a fascinating process to observe!
