At What Age Can Babies See Things?

Babies can generally see things after birth, but their visual system and nervous system are not yet fully developed, and they can only see things within a relatively close range. The visual system of fetuses usually begins to develop at 32-34 weeks, so infants have relatively good visual development after birth and have certain sensory functions. They can focus on objects within a range of 20 centimeters and only see objects in black and white, with a relatively small field of vision and blurred vision. However, after one week of birth, their vision tends to be myopic and can clearly see objects at close range. As they age, their visual system and nervous system gradually mature, and they can usually focus on people and objects in front of them after one month, with an expanded line of sight and field of vision. By the age of six months, the visual system is fully developed, allowing babies to adjust their focus to see objects clearly at different distances and to follow objects vertically. Regular hospital check-ups are necessary to closely monitor the baby's visual health, create a good living environment, and avoid exposure to strong light. If any abnormalities occur, it is important to seek medical attention as soon as possible and follow the doctor's instructions for treatment to avoid affecting the baby's health.
