Visual development: after the child is born, the structure of the eyes has been formed, but the sound visual function depends on the acquired development. After the child is 3 years old, it is necessary to carry out eye care for the child regularly, understand the condition of the child's eyes, and let the child's vision develop healthily under the guidance of scientific monitoring.
Methods to promote the visual development of newborns: place brightly colored and noisy toys 25 cm away from the newborn's eyes, and move slowly while shaking to attract the newborn's eyes to move with the toys and noise. Sitting opposite the newborn, while calling the adult's nickname, move the adult's face and let the newborn look at the adult's face and move with it.
