A baby usually develops the ability to track and follow a slow-moving object by three months of age. Before this time, an infant will follow large, slow-moving objects with jerky motions and eye muscle movements.
A three-month-old can usually track an object quite smoothly. A baby should begin to follow moving objects with the eyes and reach for things at around four months of age. Depth perception is the ability to judge objects that are nearer or farther than other objects.
Depth perception is not present at birth. An infant's color vision is not as sensitive as an adult's. It is hard to tell if babies can distinguish colors because their eyes might be attracted by the brightness, the darkness, or the contrast of an object against its surroundings, and not by the color alone. By two to six weeks of age, however, a baby can distinguish black and white. An infant is born with the ability to see facial features at arm's length but is attracted instead to high-contrast borders of objects.
For example, a baby will gaze at the edge of a face or the hairline when looking at a human face. By two to three months of age, a baby will begin to notice facial features, such as the nose and mouth. By three to five months, most babies can differentiate between their mother's face and a stranger's face. An infant's vision continues to develop and change.
