After teaching a group of new parents about their newborn's eyes and vision, which statement by the group indicates effective teaching?
A) "Our newborn can see at distances of about 1 to 2 feet."
B) "We won't know the baby's eye color until he's at least 6 months old."
C) "A baby can easily distinguish colors, but they must be bright colors."
D) "A newborn can focus with both eyes at the same time shortly after birth."
B
Response:
The eye color of an infant is determined by 6 to 12 months of age. A newborn sees best at distances of about 8 to 10 inches. The optic nerve is not completely myelinated, so color discrimination is incomplete. The rectus muscles are uncoordinated at birth and mature over time, so binocular vision may be achieved by 4 months of age.
