Final answer:
At 1 month, an infant has limited ability to see clearly, mainly light and dark. Their vision will develop over time to include the ability to focus on small objects, see colors and shapes, and achieve perfect visual acuity.
Step-by-step explanation:
At 1 month, an infant has limited ability to see clearly, mainly light and dark. Their vision is not yet fully developed, and both the retinas and the parts of the brain involved in vision are still immature. They can only focus on objects that are directly in front of their face and around 18 inches away. As the infant grows, their vision will continue to develop, and they will gain the ability to focus on small objects, see colors and shapes, and eventually achieve perfect visual acuity.
