Visual development of children at all ages and precautions

Abstract: the visual development standard of children aged 1 ~ 3 can reach about 0.1 ~ 0.6, and it is 0.4 at the age of 2. The distance of things can be distinguished, and the field of vision can keep up with the rapidly moving equipment and see clearly.

newborn period (0-28 days)

and

eye and eyesight development

and

baobaobaogang had a reflection on light when he was born, but the eye development was not complete, the visual structure and optic nerve were not mature, and the eyesight was only 1 / 30 of that of adults. He can follow the object in front of him, but his line of sight is only about 45 degrees. And they can only chase people who are 18 ~ 38 cm in front of them. Newborns prefer complicated shapes and curves, as well as the contrast color of light.

and

focus on health care:

and

pay attention to the size, shape, position, activity and brilliance of children’s eyes, find congenital abnormalities as soon as possible, and prevent and treat infectious eye diseases originating from the birth canal.

1 ~ 3 months

after the child’s full moon, he has the ability to pay attention and fix his eyes. He can see the person holding him. He can’t last too long, and his eyes are easy to lose harmony.

and

after three months, the baby’s vision has reached 180 degrees, he can also see his own hands and feel his own existence.

at this time, the vision of most infants can smoothly “follow” moving objects, and can also temporarily fix their vision on an object.

4 ~ 6 months

the baby’s retina at this stage has been well developed. It can see from near to far, then from far to near, and start to establish a three-dimensional sense at four months.

and

the baby will look for the sound origin with the visual field, or track moving objects. For example, when the mother moves around the room, the baby’s eyes will move with it;

at this time, the baby can change his body and will reach out to catch the equipment seen by his eyes, such as the small pendant hanging above the crib.

and

at this time, the eyesight is about 0.1.

after 6 months, the baby’s eyes can aim at the focus and can adjust his posture so that he can see the object he wants to see. When

and

are 8 months old, they will respond to things that suddenly dissipate in front of them. They like to track the objects in front of them with their vision;

and

have harmonious eyes and hands.

at this time, the baby’s eyesight is maintained between 0.1 and 0.2. After 8 months of

and

, the baby can recognize his relatives with his eyes.

and

babies at this time actively use their full body of sensory organs, such as vision, hearing, especially touch, to understand the world.

at the age of one year, the eyesight is about 0.2.

if children are easy to fall and trip over objects when learning to walk, they may have eyesight problems.

and

health care key points within 1 year old: stroll around with your baby

and

to avoid intraocular deviation: many parents like to tie a rope in the middle of the baby’s bed bar and hang some lovely toys on it.

and

if a child’s eyes look closely and regularly, it may develop into esotropia, which is commonly known as “cockfighting eye”.

the development of eyes and eyesight of children aged 1 ~ 3 years old

the development standard of eyesight of children aged 1 ~ 3 years old can reach about 0.1 ~ 0.6, and it is 0.4 at 2 years old. The distance of things can be distinguished, and the field of vision can keep up with the rapidly moving equipment and see clearly. From the age of one, they like to contact new things, so their ability of harmony between eyes and hands has grown rapidly, and their ability of visual recognition has also improved greatly at this stage. At the age of 3, it is 0.6. He has sharp vision and likes observation. He will lure his hands to contact new things through his eyes, so that his eyes and hands are more harmonious and smooth; The establishment of

and

stereovision is nearing completion. Key points of

and

health care: strictly prevent eye trauma. The children of

and

gradually grow up and have a wider range of activities. They also learn to run, which increases the possibility of eye trauma.

and

at this time, we should strengthen the safety education for children, such as not running with sharp objects such as pencils and chopsticks;

and

when using detergent, the family should let the child avoid it to avoid splashing liquid into the child’s eyes and causing chemical burns;

if dust and other foreign matters enter your eyes, do not wipe them with an unclean handkerchief to avoid scratching and secondary infection outside your eyes.

4-6 years old children’s eyesight has gradually matured and the clarity of eyesight has increased. They can reach 1.0 at the age of six, reaching the level of adults. At this stage, if the child’s eyesight is different, there are obvious signs. Like to watch TV at close range, squint or tilt your head to watch equipment, like to rub your eyes, or not interested in visual sports, which should attract attention. At this time, myopia has also appeared; When children watch TV or read books at close range and often complain that they can’t see clearly and are easy to knock down objects, they may be the primary sign of myopia. See a doctor if necessary.

and

health care focus: do not use eyes for a long time.

and

do not use eyes excessively: at this time, children’s eyes are still in an imperfect and unstable stage. Long term and close eye use will reduce children’s eyesight and produce myopia. Therefore, special attention should be paid to limiting the time for children to do their homework in close proximity, which should not exceed 30 minutes each time. You can often take your child to look far away, amuse the child, and identify a purpose in the distance, which is conducive to the relaxation of eye muscles and the prevention of myopia.

and

monitor the development of eyesight:

and

should start to monitor the child’s eyesight, especially the eyesight of both eyes, so as to find out the difference of eyesight of one eye. An eye with poor eyesight often loses the opportunity to use and develops into amblyopia. Amblyopia can be caused by ametropia (hyperopia, myopia, astigmatism), strabismus, etc. the earlier it is treated, the better the result. Before the age of 6 is the best opportunity for treatment. Therefore, it is best to have a visual inspection every three to six months. If conditions permit, it can be carried out at this stageDo a mydriatic optometry.
