Infant vision

The science of infant vision gives a verifiable basis for some practices of pediatric ophthalmology and gathers measurements intended to describe, monitor and predict:

By establishing a timeline of visual perception development in "normal" babies and comparing such data with that of babies with visual "abnormalitites" it is hoped to further the understanding of the role of early visual development in the overall visual picture of sensory growth and change.

Visual Development

Light sensitivity
An infant's sensitivity to light is much less than an adult. In order to detect the presence of light, a newborn requires 50 times as much light to be present compared to an adult. A three-month-old requires 10 times as much.[1]
Color sensitivity
A newborn baby is only able to see in shades of grey. However, after just one week, they will be able to see red, orange, yellow, and green colors.[1] Babies should be able to see the full rainbow, including blue and violet, by five months.[2]
Visual acuity
The newborn’s visual acuity is approximately 20/400.[3][1] Acuity improves to about 20/25 at six months[1] and usually reaches 20/20 by age two.[3]
Depth perception
Depth perception will not be present until around the fifth month of age.[2]
