3 big questions in eye care
It is said that the eyes are “windows of the soul”. Although the babies just born are not enough to express their inner emotions, just looking at their dark and bright eyes is just fascinating.
However, joy is often accompanied by accidents: how can you protect your baby’s beautiful eyes from harm?
What problems need attention?
The mothers raised many questions, and on several issues that everyone is generally concerned about, the reporter interviewed the director of the ophthalmology department of Guangzhou Children’s Hospital, and the chief physician Xiang Daoman.
1Baby should the light be turned on or off while sleeping?
Does the light affect the baby’s eyes?
Experts answer questions: the first thing to be clear is not to turn on the lights to sleep.
There are several reasons: children secrete growth hormone during sleep. When the light is on, the growth hormone level will drop; another saying is: sleeping for a long time may induce myopia, because the eyeballs are still separated even through the eyelids.Photosensitive.
From the light and dark of the light, it is implied that the light is too strong or too dark. The light that is too strong often depends on the eyes to adapt. The light that is too dark can make people see clearly and easily lead to visual fatigue.
The appropriate light should make the body feel comfortable, such as the desk lamp light or ordinary illumination light that is usually used for learning, which is equivalent to the intensity of a 40-watt incandescent lamp.
However, it should be noted that the AC light is always in a strobe state. When the frequency is low to a certain degree, it is easy to cause visual fatigue, so it is best to choose a DC light with a high flicker.
The answer is: In addition to the lights, many mothers are also quite worried about the strong light from the flash and sunlight.
Xiang Daoman, director of the Department of Ophthalmology and Chief Physician of Guangzhou Children’s Hospital, said that babies younger than a few months because their maculars are not fully developed, their eyes often fail to respond to the intense flash of light and instantaneous illumination.
If the baby always flashes when shooting, it is easy to cause damage to the baby’s eyes.
But for daily sunlight, the baby will have instinctual self-protection consciousness, such as squinting eyes, closing eyes, etc., unless it is necessary to pay due attention when the sun is exposed in July or August, usually just not direct sunlight.
2 I heard that hanging a colorful toy in the middle of a baby cradle for a long time will turn the baby into a “cross-eye”, is that so?
Experts answer: There is such a statement, mainly because parents think that the baby’s vision can be similar to that of an adult within a few months of birth.
But in fact, the newborn baby’s eyesight is very low, only a few tenths of a minute, and eye movements are just unintended.
Only a few days after birth will the baby see the lights.
After two weeks, the baby’s eyes are illuminated with a flashlight, and he or she can stare and follow the flashlight to shake the eyeballs.
3-6 weeks baby can look at something bigger.
The eyes of 2 months can follow the hand of an adult, and the eyes of 6 months can rotate with the head. At this time, the baby can also look at the colorful toys for half a minute.
It was not until 9 months old that the baby’s vision reached 0.
So hanging on the cradle, toys that are tens of centimeters away from the baby are more likely to be “heared” rather than seen, so don’t worry about becoming “cross-eyed.”
The answer is: even if the baby’s vision is poor, they still need proper light stimulation and shape stimulation, otherwise they may become amblyopic or even blind.
Some babies like to stare at the TV. Director Xiang Daoman said that the TV picture is also effective for stimulating the eyes, but cannot be watched for a long time and not too close to the TV to avoid being radiated.
Under one year of age is a sensitive period of vision development. If there is no obstacle, vision will leaps and bounds, but if you go to congenital cataract, congenital glaucoma and other eye diseases, it will even hinder vision development and even cause blindness and irreversible.
In this case, the doctor suggested that it is best to perform the operation in about 3 months, and the effect is difficult to guarantee after prolonged.
3 After the baby is born, there is always too much shit in the eyes. It seems that it cannot be wiped cleanly. Is it born with a strong secretion?
Experts answer: There are many secretions in the retina of the eyes of normal babies. When there are many secretions, there are symptoms such as shit and tears, we should consider the existence of abnormal conditions.
The above symptoms within a few days of birth may be neonatal conjunctivitis, and the etiology includes conjunctival infection of the eye caused by birth through the birth canal.
Some conjunctivitis is more serious. If the eyes have purulent secretions, called “pus leaking eyes”, it can cause the mother to be infected with gonorrhea and may also be caused by chlamydia.
If the above symptoms occur more than one month after birth, it may be neonatal dacryocystitis, which is manifested as tears, turbidity, and blurred things.
The main cause of dacryocystitis is overlapping lacrimal ducts. Normal tears are not secreted at all times, and the lacrimal ducts are responsible for transporting the tears to the nose and swallowing them through the throat.
Once the duct is blocked, tear accumulation can cause disturbances, and if the cornea is traumatized, the problem may be more difficult to control.
The answer is: the above eye diseases are mainly for term infants.
There is a more serious eye disease in preterm infants after birth, namely deformed retina.It is usually asymptomatic at an early stage, and when the symptoms appear, the eyes are blind and irreversible.
Parents in this category need to be aware of the disease and take their children to the hospital for screening two to three months after birth.
