- Vision newborns - stages of development
- they see kids
Since the birth of sight helps the child gradually develop physically, mentally and emotionally, enabling it to receive visual information.Suppose first that he sees quite a bit, and then it gradually increases the field of view and exploring the world around.
When developing vision
Unlike the ear, which can be considered completely formed in the first month, newborns vision gradually improved within 6-8 months.By this age, the baby sees the world is almost the same as adults.
Although physically able to see his eyes immediately after birth, the newborn brain is not yet ready to handle all incoming visual information.
Gradually his brain develops, and with him - the ability to see clearly, which helps to understand and recognize the world around us.At the very beginning of life a baby can see your face, bent over him, but month after month, the range of his vision grows.
How is the vision
At the beginning of a newborn baby can focus on an object at a distance of 20-30 cm from himself - that is, to distinguish your face when you hold him in my arms.In addition, the baby can observe the light, shapes and movement, but it looks blurry for him.During this period, the most interesting thing for him - your face (later it will be interested in contrasting patterns).
At birth, the child does not know how to use both eyes at the same time, so his pupils can sometimes wander independently or go to the bridge.On the first or second month of life the baby learns to focus and keep an eye out for a moving object.Rattle, you move in front of his face, will fascinate him - he discovers his new ability.Also, the baby can delight such a simple game with you - bring your baby to face, look into his eyes and slowly translate gaze from side to side, and he will take care of your eyes.
Even a newborn baby sees the color, but it is difficult to distinguish between similar colors, such as red and orange.Therefore, very young children like black and white or contrasting patterns.In the next few months baby's brain learns to distinguish between colors.He will begin to prefer bright colors simple and more complex patterns.Help the development of the baby, showing him pictures, photographs, books and toys.During this period, he will develop the skills of tracking objects.
child develops depth perception.Previously, it was difficult to understand where the object of it size or shape, to reach out and take it.By 4 months of development and motor parts of the brain responsible for vision, allow it to coordinate their movements and to grasp the visible object.Help him to practice this, offering toys that are easy to take in hand, like rattles (otherwise he will miss other objects to which it is easy to reach - for example, your hair Hair: structure, characteristics of growth and development , earringsor glasses).
child is better able to distinguish between small objects and moving objects.He was even able to understand that the object in front of him when he sees only his part.Evidence that he becomes aware of object permanence (understand that things exist even when he does not see them) - the delight with which children play hide and seek ("Cuckoo").Also, the baby starts to distinguish similar shades.
If at birth the child's vision was about 20/200 or 20/400, by 8 months it is completely formed and has the same depth and sharpness, as in adults.Although he was more interested in similar objects, he can distinguish between people and objects at the far end of the room.By the way, at this age the eyes usually get a permanent color (hereinafter, it can only change slightly).
Make sure that every time a child doctor examination drew attention to the eyes.The doctor can check whether the normal eye kid look and how well they move, there are no signs of vision problems.If you or your partner have a family history of vision problems or eye disease, tell your doctor.Examination of visual acuity using tables with symbols or letters for the first time carried out in 3-4 years.If a child show up any problems, the pediatrician may refer it to the pediatric ophthalmology.It is important to diagnose and treat eye diseases start as early as possible, because later in life it will be difficult or even impossible to do.
Studies show that babies are most popular with human faces, rather than patterns or pictures.
So give your child the opportunity to look at his face close (especially the newborn).Approximately one month baby begins like any objects that move in front of him.The stores for children full of special educational toys Educational Toys , but just the simple delight of babies toys or any objects from the household.
carried rattle (or any other bright object) in the face of the baby from side to side, and then try to move it up and down.This will attract his attention, but keep an eye out for the vertical movement of the baby to learn to just 3-4 months.Pay attention to other things that attract children - such as birds or leaves for a walk.
develop a child's interest in color - a major first, then more complex shades.To do this, perfectly suited mobiles bright, colorful posters (hang near a changing table), and multi-colored children's books.
The doctor will check the child's vision during a routine visit, but if something seems abnormal to you, tell us about it.For example, they may be such signs.
- child does not follow the object with both eyes, although he was already 3 or 4 months.
- baby's eyes is not enough to move freely in all directions.
- child all the time to move the eyes and can not stop look at one point.
- child is constantly decimated, one or both eyes roll.
- One pupil appears white.
- child is too sensitive to light, watery eyes constantly.
If your child was born prematurely, had a higher risk of vision problems such as astigmatism (blurred vision), myopia Myopia (nearsightedness), retinopathy (abnormal development of blood vessels eye, which can lead to blindness), orstrabismus (crossed eyes).Tell your doctor that the child was born prematurely.
