How to judge whether a child is short-sighted, 6 life details you need to know

Abstract: when a distant target cannot be seen clearly, children often take the method of squinting to make up for it, because when squinting, the eyelids can block part of the pupils, reduce diffuse light and reduce the influence of astigmatism, so as to temporarily improve and improve visual acuity., In recent years, myopia is becoming younger and younger. Whether infants, preschool children or adolescents may have vision problems. Due to the carelessness of parents, it was too late to find the child’s myopia, delaying the opportunity for correction. So, how can we find children’s myopia early and in time?, Why do children have myopia?, Children’s unreasonable eye habits, such as TV and video games in the process of eating and taking the car; Lack of outdoor activities; Genetic factors of children’s vision caused by parents’ high myopia; Some eye diseases, etc. These will cause abnormal visual development of children., 2. What is the child’s normal vision?, Within 1 month: one week after birth, the baby’s vision tends to be hyperopia. He can focus his vision on objects 8-15 cm away and follow moving objects with his eyes., Within 2 months: at 2 months, the phenomenon of visual concentration of infants becomes more and more obvious. They like to see moving objects and familiar adult faces. Can look at objects harmoniously, can distinguish colors, but can’t distinguish depth., 3-4 months: can fix the visual object in 3 months, see the object about 75cm away, and the visual acuity is about 0.1. The fixation time was significantly prolonged. Very sensitive to color. Babies have a preference for color and like to see bright and bright colors, especially red., 5-6 months: the number of blinks increases, you can accurately see the objects in front of you, pick them up and play with them in front of you. For more than 6 months, the eyes can follow the moving object up and down by 90 degrees. At this time, the child’s vision can reach 0.1.,

myopia has gradually become younger in recent years, and vision problems may occur in infants, preschool children and adolescents. Due to the carelessness of parents, it was too late to find the child’s myopia, delaying the opportunity for correction. So, how can we find children’s myopia early and in time?

1 Why do children have myopia?

and

children’s unreasonable eye habits, such as TV and video games in the process of eating and taking a car; Lack of outdoor activities; Genetic factors of children’s vision caused by parents’ high myopia; Some eye diseases, etc. These will cause abnormal visual development of children.

2 what is the child’s normal vision?

within 1 month: one week after birth, the baby’s vision tends to be hyperopia. He can focus his vision on objects 8-15 cm away and follow moving objects with his eyes.

within 2 months: at 2 months, the phenomenon of visual concentration of infants becomes more and more obvious. They like to see moving objects and familiar adult faces. Can look at objects harmoniously, can distinguish colors, but can’t distinguish depth.

and

for 3-4 months: after 3 months, you can fix the visual object, see the object about 75cm away, and the visual acuity is about 0.1. The fixation time was significantly prolonged. Very sensitive to color. Babies have a preference for color and like to see bright colors, especially red.

and

5-6 months: the number of blinks increases, you can accurately see the objects in front of you, and you can grab them and play with them in front of you. For more than 6 months, the eyes can follow the moving object up and down by 90 degrees. At this time, the child’s vision can reach 0.1.

7-8 months: able to distinguish the distance and space of objects; Like to look for those suddenly missing toys; Play hide and seek with the baby and observe whether the baby’s excitement and response are timely.

9-10 months: vision can move up, down, left and right with moving objects, follow falling objects, look for falling toys, and identify the size, shape and moving speed of objects.

1-3 years old: Children’s vision can reach about 0.1 ~ 0.6. Generally, you can judge the distance of things at the age of 2, and your sight can keep up with fast-moving things and see clearly. At the age of 3, the vision was more acute, and the establishment of stereo vision was nearly completed.

4-6 years old: Children’s eyeball development has gradually matured and their vision has gradually improved. At the age of 6, they are basically close to the level of adults. At this stage, if the child has abnormal vision, there are obvious signs. Like watching TV at close range, squint or tilt your head, rub your eyes, or are not particularly interested in visual activities, which should be paid attention to and need to be checked and corrected in time.

3 how to judge whether a child’s vision is normal?

before the age of six or seven, children’s refractive state will change with the development of the eyeball, so our common myopia can be predicted in advance. In order to understand the refractive changes of children in detail, find abnormal refractive development in time, take children for refractive examination regularly, and establish perfect refractive development files.

in addition, parents should carefully observe their children’s performance in learning and daily life. They need to pay attention to these six small details. If they find the following situations, they may be early signs of myopia. They should be vigilant and take their children to a professional eye hospital for detailed examination in time.

  1. Squinting: when a distant target cannot be seen clearly, children often squint to make up for it, because when squinting, the eyelids can block part of the pupils, reduce diffuse light and reduce the impact of astigmatism, so as to temporarily improve and improve visual acuity.

  2. Rub your eyes: when you can’t see the target clearly, you often rub your eyes with your hands in an attempt to see more clearly.

  3. Crooked head: it often happens that crooked head watches TV. It is also because when crooked head, it can reduce the interference and influence of some scattered light. Some children will even form the habit of crooked head.

  4. Proximity: it is often shown when watching TV, close to the TV as much as possible, and when reading and writing. Lie close and low.

  5. Complaint: due to unstable eyesight, some children will complain that the light in the classroom is too dark, or that they can’t see clearly due to the reflection of the blackboard, and many children say that their eyesight is poor during self-study at night.

  6. Error: the target in the distance is not clear, and you don’t fight when you meet an acquaintancegreet. You will copy wrong questions in the exam. You can trip or bruise by something when you act in the dark. Others show a decline in academic performance and often have to borrow other people’s notes to copy, etc.
