Why the eye color of a newborn changes. Causes of strabismus
What is the vision of infants?
Newborns see the world around differently than adults. The image on the retina of an infant is modified, i.e. the whole furnishings and objects are upside down. As they mature, the cerebral cortex undergoes a series of changes, and in this connection the visual apparatus changes. When a “normal” vision appears in a person, it is difficult to say - as long as modern technologies have not found the answer to this difficult question. But it can be said for sure that the crumbs have poor eyesight, the child sees only very large objects. The nature itself carefully treats the visual stimulation of children, so that in the first months of life it is mostly just a mother's face. Already in the second week, the baby can briefly fix his gaze. Today we will find out what color the eyes of a newborn baby. Did you know that after a child reaches the age of two months, the oculist can reveal a squint (if there is one)?
When does a newborn's eye color change?
Approximately from 4 months of age, and in some even after a year, the color of the iris changes. Its hue depends on the amount of melanin present. In most cases, the eyes of newborns have a light gray or light blue color. Gradually, the production of pigment increases, and the eyes, respectively, change the original shade. People with dark eyes have more melanin in the body several times. Changing the color of the iris can occur more than once in the life of a baby. Only by four to five years normal vision is formed.
It is proved that the pigment "melanin" can be inherited, at the genetic level, not only from parents, but also your ancestors. Often, the color of the eyes of a newborn depends on this factor. In medical practice there were cases of the birth of a child with heterochromia (eyes of different colors). There is nothing dangerous about it. This feature does not affect human health.
Strabismus in newborns: causes
In infants up to a month this disease is often observed. Strabism, or strabismus, occurs due to weakened eye muscles.Infants are not able to control the coordination of the movement of the eyeballs and for this reason they look in different directions. Parents immediately begin to panic and sound the alarm, although there is nothing terrible (in the first month). Usually, a similar physiological process disappears on its own as it grows, just as the eye color changes in a newborn. If the strabismus does not pass at an older age, then this may indicate the presence of various diseases. In the first months of the baby's immune system has not yet been formed, therefore, acute viral, infectious and inflammatory diseases can give a complication of the eyes and cause this pathology. One of the reasons for the development of strabism, according to doctors, is too close to the location of toys.
If after six months the vision has not returned to normal, then it is necessary to contact an ophthalmologist. The sooner treatment is started, the easier it is to restore the work of the eye muscles. Otherwise, the disease may progress, and this will affect the vision.
