Final answer:

A newborn's vision, as measured on the Snellen chart, is estimated to be 20/200. This implies that what a newborn sees at 20 feet, a person with normal vision could perceive at 200 feet. Their vision improves significantly in the months following birth.

Explanation:

As measured on the Snellen chart, a newborn's vision is estimated to be 20/200. The Snellen chart is a widely used tool to measure visual acuity, which represents a person's ability to discern letters or symbols at a specified distance. For an individual with normal vision, the smallest letters that can be read at a distance of 20 feet are those that subtend 5 minutes of an arc. For newborns, their vision is still developing, and the acuity is far from the 20/20 that is considered normal for adults.

Given the options provided, the one that most closely approximates the typical visual acuity of a newborn would be 20/200. This means that what a newborn can see at 20 feet, a person with normal vision could see at 200 feet. Newborns' vision improves as they grow, with significant development occurring in the first few months after birth.
