Abstract: it is generally believed that most newborn infants are hyperopia. Because the eyeball of infants is smaller than that of adults, the eyeball of infants at 6 months old is only 2 / 3 of that of adults, and the distance between the eye axis is shorter than that of fully developed normal eyes, so the image will be formed behind the retina to form hyperopia.
many parents worry that their children will get myopia too early, so they are very concerned about their visual changes. Many parents believe that if the child’s vision is less than 1.0, it must be abnormal, and corrective measures need to be taken.
although the visual acuity of 1.0 is at the edge of myopia, the development of children’s visual acuity has a process, which is gradual. We can’t simply evaluate it according to the visual acuity standard of adults.
vision development standard for children aged 0 to 6
in view of the problem that it is difficult for parents to identify their children’s vision, Xiaobian has prepared a comparison table for children’s vision development at various stages. You can refer to this to understand their children’s vision:
generally believe that most newborn babies are hyperopia. Because the eyeball of infants is smaller than that of adults, the eyeball of infants at 6 months old is only 2 / 3 of that of adults, and the distance between the eye axis is shorter than that of fully developed normal eyes, so the image will be formed behind the retina to form hyperopia. From the birth of the child to the age of 7, his eyeball developed most rapidly, his eye diopter gradually moved towards myopia, and the degree of hyperopia gradually decreased.
if your child’s vision at the age of 2-5 is not normal 1.2 or 1.5, but slightly hyperopia (about 0.7-0.8), there is no need to panic and hurry to wear glasses for him. It would be self defeating to insist on wearing glasses for him.
0 to 6 years old is the key period of vision development.
children’s vision gradually develops from 3 to 6 years old, and is completely stable around the age of 12. Usually the best correction period for children’s myopia is before the age of 6. Experts say that some vision diseases miss the best correction period, and the probability of recovery will be greatly reduced. Therefore, parents should pay as much attention to their children’s vision problems as possible, so as to achieve early detection and early treatment. And prevention is more important! However, due to the child’s relatively young age, low cognitive level and lack of expression ability, the discovery of visual diseases becomes more difficult.
under the influence of the popularity of electronic products and academic pressure, the phenomenon of low-age myopia is becoming more and more common. According to statistics, the rate of poor eyesight of preschool children is 10%, and the rate of myopia of students in grade one of primary school is 20%. Therefore, parents had better take their children to have eyesight examination every 3-6 months from the age of 4, so as to find problems and take measures in time.
several simple ways to find children’s vision problems
parents can identify children’s vision health through a series of simple methods at ordinary times:
1. Optical response: newborns have a sense of light. When exposed to strong light, they will close their eyes and frown, and they will have a strong response to light in two months. If the child does not respond to light irradiation, it indicates a serious visual impairment.
2. Gaze reflex and follow movement: children 2 months after birth can start to look at large objects in front of their eyes and follow the target to rotate their eyes in a small range; At 3 months, you can watch and follow the toy at will, and your head rotates with it; At 5 months, the development of the baby’s macular center has been completed. It can distinguish people’s faces and be happy with their favorite colors. Poor vision or nystagmus is indicated if the target cannot be fixed stably, or shows aimless search or rhythmic eye movement.
3. Covering test: cover both eyes alternately to observe children’s behavior. When covering the eye with poor eyesight, the child does not care. When covering the eye with good eyesight, the child will push away the hand or object covering his eye with his hand, because he is forced to use the eye with poor eyesight at this time, and the child will be agitated and cry because of unclear vision.
generally speaking, parents should also be vigilant when they find that their children have the following performances:
a. the habit of watching TV comes to the front of TV;
B. blinking and rubbing eyes often occur;
C. like to look sideways when looking at people and things;
D. strabismus (commonly known as cockfighting eye);
E. often squint at things and often look at things sideways.
when one or more of the above situations often occur, especially items B to e, parents had better take their children to professional ophthalmic institutions such as multi view health vision center for pupil dilation optometry to determine whether their children have strength damage.
