Development process of visual health

With the growth of age, each child's vision at different ages is different, but there is a minimum value. Generally, one to two years old can develop a vision of 0.2, the minimum vision of three to four years old should be 0.5, and the minimum vision of five years old should be 0.6. Therefore, the child's vision can't be evaluated by numerical values at first, only whether the binocular vision is balanced and whether it reaches the vision he should achieve. When the baby is 6 months old, the vision is about 0. 1, and the eye muscles have developed quite flexibly. They can not only recognize the differences between different objects, but also grasp things flexibly with their hands and put them in their mouths. For babies from 8 months to 1 year, the visual acuity is about 0. 1 ~ 0.2. They have been able to control and use their eyes flexibly. They can not only judge the distance, but also identify their parents with their eyes.

When I was in kindergarten, I began to worry about cartoons, games and Tik Tok, three killers, and I didn't escape. Because I am busy with the compulsory course of parenting health in my mother's university, I don't have much time to take care of my children. Most of them are brought by the elderly at home, but the elderly take care of the children, and the TV has become a free nanny, which saves worry and effort. They also have two kinds of pills. A clever baby must have a healthy brain. The healthy development of the brain is reflected in the activities of the cranial nerves, that is, all the activities of the baby, including crawling, sitting and eating. The development of optic nerve is particularly important for the healthy growth of infants. Vision is the baby's "window of wisdom", and 80% of the information from outside will enter the brain through this window. Fully exploring the potential ability of vision will be beneficial to the intellectual development of the brain.

0- 1 month's baby's vision is only about 0.05. He can see big objects within 20cm clearly, and can observe and track objects in a short time, but the angle of view is very narrow, so sometimes the baby doesn't respond to your action expression, probably because you are too far away or not in the baby's field of vision. There is no need to study this problem! If you really care too much about your child's eyes, then I can suggest that you supplement your child with DHA.
