Question
How long does it take for a newborn’s eyes to see things, and why do they always tear?
Answer
Generally, babies can see things shortly after birth, but their vision range is limited. By 4 weeks old, they can see a 90-degree range at a distance of 25-30 centimeters. By 3 months, their field of view should expand to 180 degrees, and they should be able to focus on a bottle. At 4 months, their hand-eye coordination skills further develop. Newborns’ eyes usually can only focus on one object for a short time, but after 1-2 months, they can focus better. At this time, you can hang colorful toys like balloons or plastic animal toys above the crib to stimulate their vision development.
