What is the typical visual acuity for a newborn shortly after birth?

• A. 20/100
• B. 20/200
• C. 20/400
• D. 20/40

Answer: (C)

In newborns, the typical visual acuity shortly after birth is around 20/400. This level of acuity indicates that newborns can see at 20 feet what a person with normal vision can see at 400 feet. At birth, a baby's vision is quite blurred, and they have a limited range of focus, primarily seeing objects that are about 8 to 12 inches away. This is due to the immature development of their visual system, including the retina and the connections to the brain that process visual information. As the infant grows, their visual acuity improves significantly over the first year, but at birth, 20/400 is the expected baseline.

While other acuity levels mentioned might seem plausible, they don't accurately reflect the visual capacity of a newborn immediately after birth. For instance, 20/100 and 20/200 indicate a higher level of visual clarity than what is typically present in a newborn, while 20/40 reflects quite good eyesight, which is much better than what one would expect in such an early stage of visual development.
