A 3-month-old baby can see objects and faces clearly at a distance of several feet, often recognizing and responding to people across a room. By this age, their vision has improved from the newborn stage where they could only focus on things about 8 to 12 inches away. Around 3 months, babies may notice you when you are halfway across the room and may even smile at you. They can also gaze at objects a few feet away, such as toys, and their eye coordination has improved enough to follow moving objects and start reaching for them
. At this stage, babies are beginning to use both eyes together, which helps develop depth perception, although full depth perception typically matures around 4 to 5 months
. Their color vision is also developing, allowing them to distinguish more colors than at birth, especially bright colors like red and green
. In summary, at 3 months old, a baby can see clearly at a distance of several feet (approximately across a room) and is developing the ability to track, recognize faces, and perceive colors more distinctly
