David Geller. pediatrician. At birth, your baby's vision was pretty fuzzy, though she could make out light, shapes, and movement. Newborns can see only about 8 to 15 inches away â just far enough to clearly make out the face of the person holding them. Handily enough, your face is the most interesting thing to your baby right at this age, followed by high-contrast items such as a checkerboard, so be sure to put in a lot of face-to-face time.
A great test of vision is just having some up-close and personal time with your baby, who by 4 to 6 weeks of age should be gazing intently into your eyes and mimicking your facial expressions. Open your mouth and stick your tongue out, and watch your baby do the same. By 3 months her vision is closer to 20/40. This means she can see almost everything in her field of vision. As a result, you'll notice your infant watch the world more and more intently with each passing day.
