What are the visual characteristics of newborns?

There are also many issues surrounding the vision of newborns. Have you seen the advertisements on TV? Now many parents are very worried about their children's vision, so people begin to pay attention to these aspects of knowledge as soon as the children are born. The question of what the vision of newborns is has aroused controversy among the public. Parents' concerns are understandable. After all, today's children are very important to all families. Next, let's talk about the issue of what the vision of newborns is.

Neonatal visual development

When a baby is born, he will respond to light, but his eyes are not fully developed, his visual structure and optic nerve are not yet mature, and his vision is only 1/30 of that of an adult. He can follow objects in front of him, but his field of vision is only about 45 degrees and his visual acuity is only 1/30 of that of an adult. Moreover, it can only track people or objects in the horizontal direction and 18 to 38 centimeters in front of it. Newborns prefer to look at more complex shapes and curves, as well as bright contrasting colors.

1. The front-to-back diameter of a newborn baby's eyeball is relatively short, and vision is not fully developed. The baby can only sense light or feel objects moving in front of their eyes.

2. Newborn babies like to look at their mother's face the most. When their mother looks at them, they will also look at their mother. This is the best time for mother and baby to communicate emotionally.

3. Newborns have active photosensitivity. They can see things around them, distinguish different people's faces, and like to look at bright and dynamic things.

4. The focusing distance of a newborn baby's eyes is about 23 cm. If you want your baby to look at something, it is best to keep it within this distance. This is also the distance between the mother's face and the baby's eyes during breastfeeding. When an object at this distance moves slowly, the baby will also move his eyes slightly.

How to test newborn baby's vision

Visual abnormalities in newborns or infants are generally difficult to detect except for obvious deformities. Parents may not notice them until half a year later when symptoms become obvious. At this time, it is too late to treat certain congenital eye diseases. So how can we detect visual development abnormalities in newborn babies as early as possible? Experts teach you a few tips:

1. Shine a flashlight into your eyes. At this time, the newborn immediately closes his eyes. If you lightly open your eyelids and shine a light into your pupil, it will shrink. This is called the pupillary light reflex.

2. Head-eye coordination movements. The newborn baby lowers his head forward with his eyes turned upward; the head tilts back with his eyes looking downward, which is called doll eyes.

3. Brief primitive gaze. Using a big red pompom and moving it 60 degrees at a distance of 20 cm from the eyes can cause the newborn to look at the red ball, and the head and eyes will slowly follow the movement of the red ball. This is called head-eye coordination.

4. Motor nystagmus. Place a paper cylinder or drum (about 10 cm long and 5-6 cm in diameter) with black vertical stripes 20 cm in front of the newborn's eyes and rotate it from one side to the other. When the newborn looks at it, nystagmus will occur, that is, the eyeballs will follow the rotation of the cylinder or drum to make horizontal movements. This is called visuomotor nystagmus.

The information about the vision of a newborn baby has been carefully told to everyone. Many people are worried about this. I hope the above description can bring great help to many parents. You can check your child’s vision based on the above data. Parents should not be too anxious. After all, the child is too young, and its growth and development will change slowly, so there is no need to worry about their conditions too early. Finally, I wish every child can grow up healthy and happy.
