Eye of a newborn is
**Core Concept:** The eye structure and development during the neonatal period is important for understanding vision and ocular health in infants. The eye undergoes significant changes within the first few weeks of life, which can lead to vision abnormalities if not addressed appropriately.
**Why the Correct Answer is Right:** The eye of a newborn is characterized by its high refractive power and immature visual system. The lens is highly curved and farsighted (hyperopic), which is necessary for focusing on objects at a distance. Additionally, the cornea is still partially transparent and the vitreous humor is not fully developed, contributing to the high refractive power. The retina also lacks the myelination of its axons, leading to reduced visual acuity (foresightedness) in newborns.
**Why Each Wrong Option is Incorrect:**
A. **False**: The lens of the newborn's eye is not highly curved or farsighted (hyperopic), and its refractive power is not comparable to an adult's eye.
B. **False**: The cornea is not immature or less transparent in newborns. It plays an essential role in focusing light onto the retina, and its transparency is not altered during the neonatal period.
C. **False**: The vitreous humor is not less developed in newborns, and it does not contribute to the refractive power.
D. **False**: The retina is not less myelinated in newborns, resulting in reduced visual acuity. Myelination of the retinal axons occurs postnatally, contributing to the development of visual acuity in the first few months of life.
**Clinical Pearl:** Understanding the developmental changes in the newborn's eye is crucial for early detection and intervention of vision-related issues, such as refractive errors or amblyopia (lazy eye). Timely management of these issues can lead to improved visual acuity and overall eye health in infants.
