Not long after colleague Xiao Yu gave birth to the baby, when sharing the good news with us, he complained about a very embarrassing thing about her husband as a novice father.
Baby was just two days old, still in the hospital, he saw baby wake up, the eyes seem to be looking at him, and then excitedly and baby nagging up, "Baby, you have been looking at me, know me not, I am Daddy, Daddy ~"
Just when the nurse came to record the baby's condition, she said in passing, "The newborn baby can't see people or objects so far away." He shouldn't have seen you at all. ”
Indeed, even if it is a healthy newborn baby born at term, the vision is not yet fully developed, not only the distance to see is limited, but also the black and white world.
In fact, if you want to say that you can see people and things at any time after the baby is born, you should be able to see them after birth.
Because the baby's vision begins to develop in the mother's belly, from about 27 weeks of pregnancy, the baby can completely open and close the eyes, to the time of birth, the baby can already see objects at a certain distance, but it is not very clear.
In the confinement, because the mother will frequently feed the baby every day, and the mother holds the baby, the distance between the baby and the mother's face is almost 20 centimeters, so the baby during the confinement period has a hazy memory of the mother's appearance.
As your eyesight continues to develop, you can't fully see the people and objects around you until you're about one year old.
As mentioned earlier, the baby's vision gradually develops after birth, from hazy to clear, from black and white to color. Next, let's talk about the vision development of babies aged 0-12 months at different months of age.
0-1 month: only light is sensed at birth, people or objects are seen are hazy, and by the time of the full moon, the baby can see people or objects within 20 centimeters.
2 months: can see people or objects within 30 cm, like to look at familiar people or objects, when the baby is lying on his back, parents take toys to move in front of the baby's eyes, the baby's eyes will move with it.
3-4 months: with the number of visual forces, from 0.01-0.05, the field of vision can reach 180 degrees, and the color can be seen, and there is a certain hand-eye coordination ability.
5-6 months: The people or things that can be seen are getting clearer and clearer, the colors are more and more, the hand-eye coordination is getting better and better, and you can grab a toy in each hand to play.
7-8 months: can distinguish the distance of objects, like to crawl around the exploration, vision increased to about 0.1, and at this time the baby has a certain memory of the appearance of the father and mother, can distinguish which is the father and which is the mother.
9-12 months: At this time, the baby's vision has reached 0.2-0.3, the hand-eye coordination is stronger, and smaller objects can be grasped by hand.
12 months later: The world is becoming clearer and clearer, the number of visual forces is increasing, and the perception of depth is further improved.
Many parents know that showing their babies black and white cards and color cards is a way to help their babies exercise their eyesight.
0-36 months, the baby's vision development is divided into three stages, different stages of training methods are also different, parents should seize the key period, follow the baby's development characteristics, correctly show the baby cards.
▲ 0-6 months: black and white visual critical period
At this stage, the baby is mainly trained in these abilities:
Binocular focusing ability; Resolution of spatial frequencies; The ability to perceive the contours of things; The ability to pay attention to things and concentrate; Observation and visual incisiveness; Detail inside the contour.
Recommendation: At this stage, the baby mainly looks at black and white cards, and looks at some classic graphics, such as:
(1) Training focus, you can see the bullseye circle pattern, the checkerboard diagram of the visual spatial frequency, etc.;
(2) To perceive the contours of things, you can choose some pictures of things that can be touched and often seen in the life of the baby, such as hats, bowls, fruits, animals, etc.;
(3) Detail observation ability and concentration, you can see some contour maps with specific details, such as pineapple, corn, crab, etc. in the following figure.
▲ 3-36 months: color vision period
The visual system perceives the edges; Contrast sensitivity; Color resolution; Spatial visual awareness.
Suggestion: At this stage, the baby has color in his eyes, and he can show the baby some colored cards, but it is also from simple to complex.
(1) First transition to simple color contrast to exercise your baby's color perception.
For example, show the baby some simple color combinations, enhance the contrast of objects, shape recognition, and improve the baby's color space, light and dark resolution.
(2) Gradually transition to a detailed color map to exercise the visual sense of space.
For example, the richer and more detailed color cards with a variety of color combinations mainly train the baby's color resolution, visual ability and observation.
When parents prepare cards for their babies, they should also follow such a rule to prepare, so that they can carry out early education training for effective babies and the effect is better.
