Children's vision standards

With more and more electronic machines in our lives nowadays, many children have basically started playing electronic games since childhood. Some children have even started playing electronic games at home with iPads before they even go to kindergarten. These changes in life have made today’s children’s eyesight much worse than before. Many children have developed myopia or even severe myopia at a very young age, which has affected their future.

Therefore, many parents pay special attention to whether their children's vision is normal, so that they can find out in time when their children are nearsighted and help them correct their vision. This requires you to first know the children's vision standards. The specific children's vision standards are:

When infants and young children are just born, the tissues and functions of the eyes are not fully developed. Most infants and young children have normal or mild farsightedness. Newborns have poor eyesight and can only see the outlines of objects within 2-3 meters.

The eyes of a two-month-old baby can move with the movement of the target;

The visual acuity of a 4-month-old baby is 0.02-0.05;

The visual acuity of 5-6 month old infants is 0.04~0.08;

7-8 month old babies have fixed vision and can look in one direction for a long time.

One-year-old children can identify organs such as eyes, ears, and nose;

The visual acuity of children aged 2 to 3 years old reaches 0.5 to 0.6;

The visual acuity of children aged 3 to 4 years old reaches 0.7 to 0.8;

The normal vision of children aged 5 to 6 is close to 1.0;

And 1.0 vision is standard normal vision.

By the age of 20, the eyeball is fully developed and the visual acuity can reach around 1.0 to 1.5.

Characteristics of children's vision development:

The eyeball of a newborn is almost perfectly round in appearance, and the adjusting ability of the lens and ciliary muscle is poor. After parallel light passes through the refractive system, the image falls behind the retina, which often manifests as farsightedness. After about 6 years old, children's vision develops gradually from hyperopia to emmetropia. This process is called emmetropization. When the monocular naked eye distance vision (5 meters away) reaches 1.0 (5.0 on the logarithmic visual acuity chart), the eye is emmetropic. As we age, the contractility of the lens and ciliary muscles weakens, and thus the ability to adjust light decreases, resulting in blurred vision of close objects. This phenomenon is called presbyopia or old eyesight.

The above is an introduction to the children's vision standards. You can use this standard to judge whether your child's vision is normal. If you find that your child's vision has declined, it is recommended that you appropriately control the time your child spends playing electronic games to prevent your child's vision from continuing to decline and causing your child to become highly myopic.
