A baby begins to see during the first few months of life as the eyes and visual system mature. A newborn has poor vision and is unable to focus on objects and can only see very big shapes and shadows. Their vision measures worse than 20/400, the biggest letter on an eye chart. By 3 months of age, objects the size of faces can be discerned by the baby’s eyes. A one year old can see shapes the size of large newspaper print. Children do not attain 20/20 vision until approximately 4 years of age.
Babies can not fixate or track objects in their first 2 or 3 months of life due to their immature visual system. However, your baby should be able to fixate and track objects by 4 months of age. An infant’s visual system is also unable to keep their eyes straight early in life. Most infants’ eyes tend to drift outward. The eyes straighten as vision develops and infants begin to use their eyes together by 4 months.
