1. What causes myopia of 600 degrees in a 1-year-old child?
Two days ago, I saw a news, Ms. Mu from Henan found that her 1-year-old son was a little blurry and always squinted, so she took the child to the hospital to check her eyesight, but the results of the examination surprised her, her child was only 1 year old, and the myopia in both eyes was 600 degrees and 650 degrees. Such a high degree is embarrassing. What is the cause of this?
It turned out that Ms. Mu and her husband were both short-sighted, so most of the child's myopia was inherited, and later under the guidance of the doctor, the child was given glasses and a series of prevention and control measures were taken, such as taking the child to outdoor activities for more than 6 hours a day and eating less sugary food. But half a year later, when they went for a follow-up, the child's eyesight was 100 degrees longer, which made Ms. Mu very devastated. Even the doctors thought it was incredible.
However, most of Ms. Mu's children's myopia is caused by genetics, and both parents are myopic.
The study found that under the same conditions, compared with children whose parents were not myopia, children with unilateral myopia had a high probability of myopia as high as 2.1 times. If both parents are myopic, the probability of a child developing myopia is 4.9 times, and if both parents are not myopic, the child may also be myopic.
2. Why do children become myopic and what causes them?
When it comes to myopia, many parents will think of watching TV and looking at mobile phones, yes, inappropriate use of eyes for a long time can cause myopia, but in fact, there are many reasons for myopia.
1. Love sweets
Many children love sugar, but too much sugar in the child's body will cause the blood to produce a lot of acid, and they will neutralize with the calcium salt in the blood, thus affecting the absorption of calcium. But we know that during the development of a child, not only the bones of the body need calcium, but also the outermost sclera at the back of the eye. If calcium absorption is insufficient, the elasticity of the eye wall will be reduced, and the child's eye axis will be elongated, which greatly increases the probability of axial myopia.
Most sweets contain sugar, which absorbs vitamin B1 during metabolism, which inhibits the activity of cholinesterase and can cause nerve impulse conduction disorders if insufficient. It can also affect the development of the child's optic nerve, the eyes become tired, and the regulatory function decreases.
2. Lighting issues
When the light is strong, the pupils will be narrowed, and when the light is dim, the pupils will be dilated to see objects clearly, but too bright or too dim lights will affect the child's vision.
3. Heightened use of the eyes
For example, in daily life, reading books, writing homework, playing mobile phones, watching TV, playing computers, online classes, etc., this high-intensity eye Xi will also cause children to become myopia. When the child is looking at the electronic screen, the pupil will continue to change, so that the ciliary muscle is in a state of tension all the time, and if the eyes are not well relaxed, it will lead to a decrease in farsightedness reserve, thus forming myopia.
4. Unbalanced nutrition
Picky eating, anorexia, or inadequate nutritional supplementation can also lead to myopia. For example, in the process of children's vision development, if these nutrients are deficient, the probability of myopia will increase. For example, protein, lutein, DHA, calcium, chromium, zinc, vitamin A, etc.
3. How to prevent and treat myopia?
1. Develop good eye Xi
First of all, the use of electronic screens should be reasonable. For children, good eye Xi can greatly reduce the probability of myopia. For infants and toddlers aged 0-3, try not to use video electronic products such as mobile phones, tablets, computers, etc., and it is better to have fewer opportunities for contact. For children aged 3-6, you can watch TV occasionally, but pay attention to the time when children watch screens, generally choose a TV with a larger screen, and the viewing time is 10-15 minutes.
Children aged 6-12 should not use the screen for more than 1 hour a day, and no more than 20 minutes at a time. And every time you look at the electronic screen, you need to look into the distance, let the eyes rest for 5-10 minutes, or do eye exercises.
Second, sit in the right position. Many children do their homework on their stomachs, tilt their heads, and lean their necks forward, which will lead to hunched backs, often tilting their heads leading to deformation of the spine, sore shoulders, and tilting their heads to see objects resulting in different reading and writing distances, causing strabismus. Therefore, to buy a table and chair at the correct height, always remember the mantra of correct reading and writing posture: keep your back straight, your eyes one foot away from the book, your fingers one inch away from the tip of the pen, and your chest one punch away from the desk.
2. Adjust the lighting in your home to increase the amount of time you spend in natural light
Try to buy eye-protecting table lamps that meet the national lighting standards, and pay attention to the ceiling lamps in the living room and bedroom. For example, when buying lamps and lanterns, pay attention to buying lamps with a color rendering index Ra higher than 90. The relevant color temperature should be controlled between 3300K-5500K, and it is recommended not to be higher than 4000K at night. At the same time, the color rendering of the lamp should also meet the standard.
In addition, on weekends or after school, try to increase the amount of time your child spends outdoors. For example, on weekends from 8 a.m. to 10 a.m. and from 15 p.m. to 18 p.m., take your child out for a walk outdoors, and the light during this time is soft and helps your child's vision development.
3. Increase sleep time
The study found that children who slept less than 7 hours per night had a 3.37 times higher risk of myopia than those who slept more than 9 hours. For every 1 hour of sleep decreased, myopia increased by 0.10 days. Therefore, the less sleep a child has, the greater the probability of myopia.
Therefore, it is also important to have a good night's sleep if you want to see better. The National Comprehensive Prevention and Control Program for Myopia in Children and Adolescents points out that to ensure children's sleep time, the sleep time for primary school students is required to be 10 hours a day, 9 hours for junior high school students, and 8 hours for high school students. If sleep requirements aren't met during the week, try to get your child more sleep on weekends if possible.
4. Pay attention to the rational combination of nutrition
First of all, children should eat less sweets and not be picky eaters. Secondly, eat more eye-friendly foods. For example, lutein, DHA, zeatin, vitamin A, protein, calcium and other rich foods.
For example, lutein, we know that lutein can be antioxidant, it reacts with free radicals, can remove these metabolic wastes, reduce the risk of macular degeneration, and lutein and zeaxanthin can absorb harmful ultraviolet rays and short-wave light in the light, helping to delay eye fatigue and aging. Therefore, we should eat more lutein-rich foods every day.
For example, DHA, which is a very important polyunsaturated fatty acid for the human body, is a major nutrient for the growth and maintenance of nerve cells, and DHA in the human eye accounts for 60% of the total fatty acids in the retina, which is very helpful for the activity of the optic nervous system. If there is a lack of n-3PUFAs such as DHA in the diet, the amount of DHA in the brain and retina is reduced, and the visual sensitivity to light, learning Xi memory are affected.
For example, vitamin A and carotenoids: if the human body lacks vitamin A, the ability of the eyes to adapt from light to dark will decrease, and the eyes will be dry and unbalanced. You can eat more pork liver, carrots, bell peppers, citrus, etc.
For example, anthocyanins, anthocyanins can increase the blood flow of fundus microcirculation, accelerate ocular metabolism, and enhance the protective effect on ocular capillaries. You can eat more blueberries, purple potatoes, purple cabbage, purple grapes, etc.
However, a single diet does not provide the nutrients that the eye needs as described above. Many parents supplement lutein to improve their children's vision, but find that the effect is average, because lutein can only protect vision in the true sense of the word when supplemented with DHA.
But my mother's child is amblyopia + farsightedness, and he began to eat lutein at the age of 3, but the effect is average, and later the doctor confirmed that lutein and DHA have a better effect together. Why?
Your child's retina is filled with tiny blood vessels that carry more oxygen for growth and development, increasing the number of oxygen free radicals and making DHA in the retina easily oxidized. Lutein, on the other hand, can filter blue light, resist DHA oxidation, and avoid the loss of DHA in the retina. At the same time, lutein is a powerful antioxidant that can help DHA resist oxidation.
How do we get lutein and DHA at the same time?
We can supplement with lutein, which contains both of these ingredients.
For example, my mother gave my family cocoa to eat this JianleTV little monster lutein, which I compared with a lot of families to buy, my child has eaten for more than 3 months, with daily vision training (covering beads + games), the child checked the right eye 0.1 in August, the left eye 0.7, the right eye 0.4 in October, the left eye 0.8, a few days ago to check, the right eye 0.8, the left eye 1.0, even the doctor felt that the child's vision improved very much.
A few parents specifically asked me how to train their children's eyes in private, how to effectively prevent myopia, and I also shared my experience with everyone.
First of all, regardless of whether the child is nearsighted or not, he must go to a regular eye hospital for examination. The child's uncorrected visual acuity and corrected visual acuity are measured, and the child's visual acuity is checked every six months. If you notice that your child squints, rubs, blinks, or looks very close, it may be a sign of myopia.
Second, make sure your child has 2 hours of outdoor activity every day, or at least 14 hours of outdoor activity per week. It's best to do outdoor activities when the sun is shining.
Moreover, pay attention to bad eye Xi and control the amount of time children spend watching electronic screens every day, no more than 30 minutes a day before the age of 6. At the same time, children should sit up straight and pay attention to their sitting posture, whether they are writing, reading, drawing, etc.
Finally, pay attention to supplementing lutein, DHA, anthocyanins, vitamin A and other nutrients, such as taking special supplements to supplement the nutrients needed by the eyes.
At that time, it took a lot of effort for Ke Ma to choose lutein, and the main reason why she chose Jianleshi Little Monster Lutein is that it is different from the products on the market that only supplement lutein, it is also rich in DHA, and the two supplements at the same time, which can not only alleviate the increase in myopia, relieve eye fatigue, but also inject nutrients into brain vitality.
Secondly, its ratio of lutein to zeaxanthin is 5:1, which is the clinical golden ratio, which ensures that the two can be absorbed as much as possible and effectively protect the optic nerve. It is rich in lutein lipids, DHA, ARA, aronia berries, zeaxanthin, β-carotene, vitamin C, vitamin D, etc., suitable for babies over 3 years old.
The Lutein of Little Monster of Ginger is selected from BASF BASF patented lutein lipid imported from Denmark, and uses advanced capsule technology to lock in freshness and ensure that lutein meets high quality standards.
Moreover, it contains aronia berries from Europe with a very high anthocyanin content, containing 1480mg of anthocyanins per 100g of aronia berries.
Because it has a sweet orange flavor, my children like to eat it very much, and the shape is also very cute, and the child accepts it very highly.
Of course, the treatment and prevention and control of children's myopia, farsightedness and other problems need to be comprehensively treated in combination with the above aspects.
