As the saying goes, "the eyes are the window of the soul", for the average flower child, this window is more like a gold edge, very precious.
Every time you take your child to the hospital for a physical examination, the ophthalmologist will always tell you a few words:
But many parents are still confused:
Obviously, we have attached great importance to the protection of children's eyes, avoiding exposing children to electronic products, and strictly limiting the time for children to play mobile phones, but why is there still a problem with children's vision?
In fact, the factors that cause children's poor vision are multifaceted.
We often only see the "superficial factors" that endanger children's vision, and ignore the four "original sins" that affect children's vision!
Congenital inheritance
Myopia, divided into physiological myopia and pathological myopia.
Physiological myopia mainly refers to myopia that occurs during development or after adulthood, and its essence is a refractive phenomenon, not an eye disease, so it will not be passed on to the next generation.
Pathological myopia, which occurs relatively early, generally occurs at the age of 5 to 10 years old, and develops rapidly, it is difficult to correct, and by adulthood, myopia may be as high as 1500 degrees, and this myopia will be inherited to children.
Surveys have shown that if a child's parents are both nearsighted, then their children have a 33% chance of becoming a nearsighted eye.
However, parents do not have to worry too much, pathological myopia is very rare in the eyes of myopia, accounting for only 2%, most people are only physiological myopia, not hereditary.
Environmental impact
In addition to the innate genetic factors, the impact of the environment on children's vision cannot be ignored.
For example, the various LED lights used in the home have gradually replaced the traditional lamps. LED lamps are energy-saving and environmentally friendly, and have a longer life expectancy compared with traditional incandescent lamps.
But a recent Weibo hot search broke this calm, showing that the French Health Bureau reported that LED lights will cause permanent damage to the retina, and in severe cases, blindness can be caused! This has aroused great concern among netizens.
Xiaoke consulted the reports of the French authorities, which mainly emphasized the damage to the retina emitted by LED lights, resulting in a decrease in vision, increasing age-related macular degeneration, and even inducing blindness.
Studies have shown that LED phones, tablets, and laptop screens don't cause damage to the eyes, but the intense light used for car headlights can damage our eyes.
Blue light harm affects a large number of people, the World Health Organization (WHO) Eye Association announced: Every year, blue light and radiation cause more than 30,000 people around the world to lose their sight.
According to data from the Ophthalmology Branch of the Chinese Medical Association, among the 420 million netizens in China, 63.5% of netizens have eye diseases of varying degrees due to blue light and radiation, such as decreased vision, cataracts, and blindness.
Worryingly, children are more vulnerable to such interference.
For example, when children watch TV, computers, mobile phones and other electronic products for a long time, they will feel eye fatigue, eye acidity, dryness, and even tears and redness, and dizziness, blue light is the culprit. When bathing children in winter, worried about the child's cold, many parents will drive a bath bully, or prepare a small sun heater for their children.
But in the process of bathing, the children's restless little eyes will always stare at the glowing things.
Because the light emitted by the small sun and the bath bully is infrared radiation, long-term direct vision will stimulate the child's delicate eyes, which can easily lead to lens injury, causing great damage to the child's vision, and this damage is irreversible, so parents should pay special attention.
In addition, turning on the lights to sleep can also affect your child's vision.
Turn on the light to sleep, the light source of the light will cause certain pressure and stimulation to the eyes, not only making it difficult for children to fall asleep, but also affecting the child's vision development.
Studies have shown that before the age of 2, the proportion of myopia in children sleeping in a room with a small night light turned on is 1.24 times that of not having a light on; the proportion of children sleeping in a room with a headlight on is 1.45 times that of not having a light.
So, can LED lights still be used?
According to the current international and domestic standards, blue retinal hazards can be classified into four types:
No Hazard (Class Zero)
Low Hazard (Class I)
Medium Hazard (Category II)
High Risk (Category 3)
At present, the basic types of hazards used as LED lighting are category zero and class I hazards, and if it is a class II hazard, there is a mandatory label (the eyes cannot stare).
LED lamps listed by the national quality inspection have a similar risk of blue light hazards to other light sources and are within the safety threshold. Therefore, these light sources and lamps used in daily life are used in the normal way and are harmless to the human eye, and we do not have to worry too much.
Lack of outdoor sports
With the emergence of a variety of electronic products that cater to children's tastes, the time that children should go out to play is completely occupied by electronic products, and the excessive use of eyes over the years, as well as eye fatigue can not be rested, resulting in children's myopia becoming more and more serious.
Survey data show that the probability of myopia in children who go out to exercise for an average of 3 hours a week is 9 times higher than that of children who usually go out to exercise for 14 hours a week.
Ophthalmologists also revealed that appropriately increasing the time of children's outdoor activities and exposing children to natural light is an effective way to prevent myopia.
Because the outdoor bright natural light can stimulate the child's pupils, make the eye retractability stronger, more contact with outdoor light, but also promote the retina secretion of dopamine agonists, this substance can effectively prevent the growth of the child's eye axis, and prevent myopia.
Take good care of your child's eyes, and parents will have no choice.
From now on, pay attention to your child's eye hygiene, avoid your child's long-term use of your eyes, help your child develop good eye habits, and regularly take your child for vision checks.
May every child stay away from myopia and have healthy, bright eyes!
