Normal range of astigmatism for one-year-old baby

Generally speaking, when a baby is just born, the degree of his eyesight should be normal. However, if the parents' diopter is particularly high, it is likely that the child will be born with congenital myopia or astigmatism problems. If a child's eye problem is caused by acquired factors, timely correction can help restore vision. Therefore, parents should not only pay attention to the growth and health of their children, but also their eye health.

Children's visual development process is gradual. Newborns generally only have a sense of light, while the vision of a two-year-old child is generally 0.4-0.5, 0.5-0.6 at 3 years old, 0.6-0.7 at 4 years old, and 0.7-0.8 at 5 years old. After children reach the age of six, their general vision can reach 1.0. The period before the age of two is particularly critical for children's vision development. During this period, the function of the eye is reversible, which means that many eye diseases can be cured during this period.

The main reasons for astigmatism in children are as follows:

One is that children use their eyes too much and too early. Nowadays, many young children have the habit of watching TV and playing with tablets for a long time.

The second is caused by some eye diseases, such as trichiasis, eye eczema, conjunctivitis, ptosis, etc. in children;

The third is unbalanced nutrition. Children who are picky eaters usually do not get enough nutrition, which will lead to some abnormalities in their eye development.

Fourth, incorrect eye posture. When children use their eyes incorrectly, they will have the habit of squinting, squinting, tilting their heads to see things, etc. These are often manifestations of astigmatism;

The fifth is genetic factors. If parents suffer from astigmatism, the chances of their children suffering from astigmatism increase.

To sum up, we know what the normal range of astigmatism is for a one-year-old baby. If a baby has vision problems when he is young, most of them are inseparable from the care of his parents. Therefore, parents need to take good care of their children at this time to avoid astigmatism in their babies too early, otherwise it will have a bad impact on their future life and study.
