Babies can see from the day they are born, and the visual development of babies needs a process, each stage has its developmental characteristics, we not only need to pay attention to the various stages of visual development of babies, but also need to prevent the baby’s eyes from being harmed. Baby’s visual development It takes a long time for a baby’s vision to develop slowly, until the age of 1 year, when he or she can basically see as clearly as an adult. Babies are born with eyes that can see. Although he can see indistinctly, he can already distinguish light, shapes and movement; he will turn his eyes towards a window or other light source. Healthy newborns begin tracking moving objects from just a few minutes after birth. As your baby tries out this new ability, a red ball that is fiddled with from in front of him can be a sight to behold. At this time, your baby may also like to play eye-to-eye with you: you put your face in front of your baby’s face and slowly move from one side to the other, and your baby’s eyes will stay fixed on you. Although your baby can see colors, he can’t yet distinguish between similar shades like red and orange. So you need to prepare some black and white or color contrasting toys for him to attract his attention. In the first month of life, the distance that your baby can focus and see clearly is only about 20 centimeters, which is just enough for him to see the face of the person holding him, which is usually you. So it stands to reason that your face is the one that your baby feels most marvelous about. That’s why you need to be closer to your baby, to be more intimate with him, to look at him in all directions more often, so that he has time to study your face properly. At 2 months, your baby is getting better at distinguishing colors and he is starting to be able to differentiate between similar shades. Your baby may now prefer the brighter three primary colors (meaning red, yellow and blue), as well as more detailed and intricate designs and shapes. Try to take advantage of this developmental trait by showing your baby bright pictures, photos, books and toys. At 4 months, your baby is starting to be able to tell how far away objects are from him, which is called depth vision (depth perception). around 4 months, your baby is also getting better control of his arms. Because he can see better, he can grab your hair, eyeglasses, earrings, or other toys that he can touch. At 5 months your baby is much better at localizing very small objects and tracking moving objects with his eyes. He can even recognize an entire object by looking at only part of it. This indicates that your baby is beginning to understand the constancy of objects and knows that they are always there even if you cannot see them for a while, so he now enjoys playing “hide and seek. Your baby may also imitate your facial expressions. Make a face in front of him and stick out your tongue to see if he knows how to imitate you. Your 8-month-old baby can see much more clearly than before, basically as clearly as an adult. In addition, he can see farther. Although your baby still can’t see as well at a distance as he can up close, he can see well enough to recognize people and objects on the other side of the room. Your 9-month-old’s eyes are likely to be close to his final color, although there may be some subtle changes in the coming months. Your baby’s vision is getting sharper and he can now recognize items the size of breadcrumbs. A baby of this age is likely to point to nearby items and ask you to bring them to him. Your baby will be able to distinguish between far and near by the time he is 1 year old. He can recognize an acquaintance coming towards him from some distance away. How can I prevent my child from getting an eye injury? Ninety percent of eye injuries are preventable. The most common causes of eye injuries in children include improper use of toys, falls from beds or stairs or onto furniture, cuts from tools and things like pencils and forks, and exposure to hazardous chemicals like paints and cleaners. So be careful to make good safety precautions in your home, eliminate any safety hazards, and put anything dangerous out of your baby’s reach. In addition, you should also pay attention to: 1, do not let your child play with firecrackers, fireworks, catapult toys like darts and slingshots, or other types of launching toys. 2. Don’t let your child and his buddies run around with sharp toys like scissors and sticks. 3. Be sure to lock up or put out of reach any chemicals that your child might get in his or her eyes or eat. In particular, be careful to put away pipe cleaners and fertilizers (such as flower fertilizer). 4, minimize the use of IPAD and other electronic products to coax the baby. Watching TV time should also be controlled.
