The baby's vision in kindergarten is only 0.6, is it myopia?
My sons are 6 years old, how come they don't even have 1.0 eyesight?
I believe that many parents have had these questions above
So, how much is your child's vision normal?
Newborn babies have eyes that are farsighted
When the baby is first born, the eyeballs are small and are farsighted. As we age, the eyeballs develop larger, approaching normal adult size around the age of 6, becoming a orthopic eye (neither nearsighted nor nearsighted). The visual acuity of the orthopedic eye should be 1.0.
After the child starts to go to school and read, the time to read up close increases, and the eyes may begin to develop in the direction of myopia. Therefore, children's vision development is a process of change, not reaching the level of normal adults at the beginning.
How much vision is normal in children?
When the child is just born, it is generally in a refractive state of hyperopia of 2.0 to 4.0D, and then, with the growth and development of infants and young children, the eyeball becomes larger, the eye axis becomes longer, the cornea curvature increases, and gradually develops towards orthodon.
About vision
At 3 months of age, it is 0.02, that is, it can track moving objects in front of you.
0.2 at the age of 1, 0.4 at the age of 2, and 0.6 at the age of 3, can read the eye chart can be used to check the vision.
It is 0.8 at the age of 4 and 1.0 at the age of 5, which is adult vision.
Vision of 1.2 can be achieved at the age of 6.
For children of different ages, different criteria should be used to determine whether the vision is abnormal. In general, the lower limit of visual norms for children aged 3 years is 0.4, the lower limit of normal vision values for children aged 4 to 5 years is 0.5, and the lower limit of normal visual acuity values for children aged 6 to 7 years and older is 0.7.
If the child's vision is lower than the lower normal visual acuity limit of children of the same age, or the difference in binocular vision is more than 2 lines, it means that the child's vision is abnormal, and it is necessary to go to a professional optometry center for examination in time.
I'd rather regret it than miss it!
How can I help my child maintain good vision?
1
Limit the time to use electronics
At present, with the popularity of television, mobile phones and other electronic products, its impact has also penetrated into the children's group, many children are addicted to watching TV programs and mobile phone games for a long time, this poor visual environment is not conducive to the growth of children's vision. Parents can give their children a prescribed time to play, for example, each play can not exceed half an hour. Follow the rules, and slowly the child will get used to obeying them.

Parents lead by example and use less electronics
When children are young, they don't know what mobile phones and iPads are, because parents are always playing on the side, so curious children also want to see what attracts parents. Then, they learned to draw here and there like their parents, and gradually became attracted to the novelty inside. Whenever parents are playing with electronic products, the child's willingness to play also tends to be stronger. Therefore, when you come home from work, parents should put their mobile phones and iPads aside to accompany their children to play and play.
3
Divert attention and spend more time with your child
A big reason why children are addicted to playing with electronic products is because there is no one to accompany them, and parents can divert their children's attention when they want to play with electronic products or cannot stop. For example, use toys to attract children, or have a family game with children, tell children interesting stories, draw with children, and so on.
4
Organize more outdoor activities and sleep 10 hours a day
Outdoor light is indispensable, "the best prevention of myopia is to increase outdoor activities." Dr. Luo said that for every additional hour of outdoor activity, the incidence of myopia is reduced by 10%. Children and adolescents should be outdoors for no less than 2 hours a day.
5
Eat a balanced diet
Childhood is a critical and sensitive period of visual development that requires an adequate supply of multiple nutrients. A high-protein, high-vitamin diet is a protective factor for refractive development in preschool children, while deficiencies of trace elements such as zinc, chromium, and calcium are risk factors affecting children's refractive development. Frequent eating of sweets, fast food, fresh vegetables, fruits and other picky eating behaviors will make the supply of some nutrients needed for children's growth insufficient, unbalanced, over time will lead to the occurrence of myopia in children.
