Infants under 3 years old are not only ametropic, but also “myopia”

Abstract: after a baby is born, the eyes must learn to see. This learning is a step-by-step process. The process of infant vision development includes: learning to focus and see distant and near objects; Learn to recognize color; Learn to use your eyes to see the three-dimensional state of objects, etc., The child’s eye structure has initially formed during the fetal period, so he can detect light in the womb., After birth, the development of infant eyes is synchronized with the growth and development of infants. After birth, the baby’s eyeball is asymmetric or skewed, which is often considered as ametropia., The process of infant eye development is the process from asymmetric sphere to symmetrical sphere. Infants are not only ametropic, but also “myopia”., Newborn babies have almost the same vision as adult blind people, It is only about 0.04 (20 / 500). In other words, newborns can only see objects close to the size and shape of the breast. The visual acuity of infants one month old is only 0.1. When infants grow to 6 ~ 7 months old, the visual acuity can be improved to 0.4 (20 / 50). Newborns not only have poor eyesight, but also are nearly color blind. They can only distinguish black, white and red colors. It has a definite meaning to reach this level – the mother’s breast is pink. After the baby is born, the eyes must learn before they can see. This learning is a step-by-step process. The process of infant vision development includes: learning to focus and see Qingyuan near objects; Learn to recognize color; Learn to use your eyes to see the three-dimensional state of objects, etc., A few weeks after birth, the baby’s eyes can be stimulated by thousands of pictures every day, through which the eyes gradually mature.,

the child’s eye structure has initially formed during the fetal period, so he can detect light in the womb. After the birth of

and

, the development of infants’ eyes is synchronized with the growth and development of infants. After birth, the baby’s eyeball is asymmetric or skewed, which is often considered as ametropia.

the process of infant eye development is the process from asymmetric sphere to symmetrical sphere. Infants are not only ametropic, but also “myopia”.

the eyesight of newborn babies is similar to that of adult blind people, Only about 0.04 (20 / 500), in other words, newborns can only see objects close to the size and shape of the breast.

the visual acuity of infants born one month is only 0.1. When infants grow to 6 ~ 7 months, the visual acuity can be improved to 0.4 (20 / 50).

Newborns not only have poor vision, but also are nearly color blind. They can only distinguish black, white and red. It makes sense to reach this point – Mom’s breasts are pink.

after a baby is born, the eyes must learn to see. This learning is a step-by-step process. The process of infant vision development includes: learning to focus and see distant and near objects; Learn to recognize color; Learn to use your eyes to see the three-dimensional state of objects, etc.

a few weeks after birth, the baby’s eyes can receive thousands of picture stimuli every day, and the eyes gradually mature through these stimuli. While the eyes of

and

are mature, they also gradually have the ability to focus, and the brain also begins to integrate the information seen by the eyes.

at first, the visual signals received by the baby’s brain were not input by both eyes at the same time, but input by each eye separately, so that the signals received by the brain are sometimes very strange. The most common reason for the strange phenomenon of

and

is astigmatism – two eyes looking in different directions. This phenomenon will end at 4 ~ 6 weeks after birth. After that, the baby will occasionally have astigmatism. This phenomenon can basically disappear at 3 ~ 4 months after birth.

and

only when the eyes rotate coordinately can consistent information be transmitted to the brain. The baby is still lacking in this point, so we sometimes see that the baby’s eyes are inclined inward or outward. In fact, this is a normal stage in the development of vision.

and

for the physical examination of infant eyes, mainly focus on the movement and coordination of eyes, and whether there is strabismus, so as to prevent amblyopia and other problems in the future. A visual examination at the age of 3 may indicate the problem.

parents often ask whether they can watch TV for infants and young children, and whether watching TV for infants and young children will affect their visual development?

and

infants have immature visual acuity and resolution. They need to receive information from all aspects in visual development, including video information.

and

can watch TV for infants and young children when they are older, but they must choose TV programs suitable for infants and young children – infant cartoons with slow action and bright colors. Moreover, the viewing time should not be too long each time, which is one of the reasons why the time of each episode of infant animation is limited. Watch as little TV as possible for children under the age of 2.
