Final answer:
Newborns have a limited ability to see clearly, mainly light and dark, at 2 weeks. Their vision gradually develops over time, allowing them to see colors, shapes, and achieve perfect visual acuity.
Step-by-step explanation:
Newborns' vision is not fully developed, but around 2 weeks, they have a limited ability to see clearly, mainly light and dark. They can distinguish between light and dark objects, but their ability to focus on small objects is still limited. It takes time for their vision to fully develop, including the ability to see colors and shapes and achieve perfect visual acuity.
