4 months old baby's vision

During the first three months, babies have a lot of trouble distinguishing color contrasts, which was why your newborn preferred bright colors and black-and-white objects. Now at four months, baby’s vision has sharpened to about 20/40. Babies at this age can pick out more subtle color contrasts, such as a red button on a red shirt. They also can see across the room, although they still prefer looking at people close-up.

Your baby’s eyes should move together smoothly and follow objects and people around the room. If you notice crossed eyes or any other vision problems, be sure to mention them to your pediatrician.

You also may notice that your baby’s eyes are starting to change color. Lighter-colored eyes may go through several changes before settling on their final shade at about six months.
