What is the normal vision of children?

I believe everyone knows the importance of vision to us. If there is a problem with our vision, it will not only affect our work and study but also bring many inconveniences to our lives. Therefore, we recommend that our readers must protect their eyesight in daily life. Vision is even more important for children. Below we will introduce to you what is the normal vision of children.

It is well known that the normal vision of adults is 1.5-2.0, so what should be the normal vision of children? Newborn babies have weak vision and short eye axes, and are all farsighted. As the eyeballs gradually develop, the vision also gradually improves.

A child's eyeball develops rapidly before the age of 8, then slows down until it begins to take shape around the age of 25.

Under normal circumstances, a child's vision is 0.2 at the age of 1, and increases by about 0.2 with each year thereafter. A child's vision should be above 1.0 at the age of 5, around 2.0 after the age of 8, and the saturated vision after the age of 14 may reach around 3.0. 1.0 is only the minimum standard for normal vision, and 1.5 is not the best vision.

Therefore, if a child over 10 years old has a vision of only 1.0, we should start looking for measures to prevent and treat vision loss. Because at this age, it is normal if it is more than 1.0. Otherwise, it may weaken after the age of 14, or even become extremely myopic.

suggestion:

Multiply the age by 0.2 as the reference standard for vision of preschool children. Since this reference standard is based on age and eye development, it is scientific and reasonable, and can be said to be suitable for everyone.

All preschool children whose vision is lower than their age multiplied by 0.2 are subject to prevention and treatment. This raises the starting point of prevention and control, takes effect in advance, increases the room for maneuver in prevention and control, and reduces the difficulty. Because there is no lesion in the structure of the eyeball at this time and the refractive power is still normal, prevention can be achieved before the disease occurs and myopia can be eliminated before it develops.

In the above article, we introduced the importance of vision to our human body. We recommend that our readers protect their eyesight in daily life. The above article gives us a detailed introduction to the normal vision of children.
