A: Infants should be able to fixate (“lock” their eyes) on an object soon after birth and follow a moving object by the time they are 3 months old. You can use a toy or bright-colored object to determine whether your baby has reached these early milestones. If you have any concerns about your baby’s eyes, we can help. Greater Vision participates in InfantSee, a program that offers a free exam to infants under 12 months of age. You can find more information here.
