Is myopia related to heredity?
Myopia and heredity do have a certain relationship. If the child is myopic, especially highly myopic, it is related to the genetic aspect. If the parents are pathological myopia, that is, high myopia and a series of lesions of the fundus retina, the risk of myopia in children will be very high. If parents are low-grade myopia, the degree is about one or two hundred degrees, and their children's myopia is not so related to heredity.
Studies at home and abroad have shown that myopia is affected by multifactorial combinations. Myopia inherits only 5% of the genotype. Many children's myopia is caused by a combination of factors such as the acquired environment and eye hygiene. In the case of already myopia, we recommend preventing the aggravation of myopia due to acquired factors. If the child is at risk of myopia, we recommend a detailed examination at a regular institution as soon as possible.
We are more concerned about how children can use their eyes safely, hygienically and healthily. Generally speaking, when a child is three years old, he should have a certain farsighted reserve, about 200 degrees; at the age of eight, the farsightedness reserve should be 150 degrees; at the age of 12, the farsightedness reserve should have 100 degrees. That is, 12-year-olds should still have some reserve of farsightedness, not myopia. If your child's vision is already lower than the above-mentioned hyperopia reserve, especially below the 100-degree reserve, it is more likely to develop myopia.
Pay attention to eye hygiene. First of all, follow the "20-20-20" rule with the eyes for a long time, if it is a child of about ten years old, after 20 minutes of continuous use of the eyes, you should look 20 feet away, which is equivalent to 6 meters away, and at least 20 seconds away, which is a better way. At the same time, the posture of reading and writing should also be kept upright. Can not lie on the stomach, together, should follow the "one punch, one foot, one inch" eye rules, holding the pen posture should also keep the finger from the tip of the pen more than 3 cm.
At the same time, we hope that parents and children will work together to cooperate with our country's burden reduction policy. Weekends should no longer increase the academic burden, but should be outdoors for physical exercise. If you can have more than two hours of outdoor activities a day and receive natural light, this is effective for visual protection.
In general, in addition to genetic factors, it is more important to use the eyes reasonably, hygienically and healthily the day after tomorrow, and increase outdoor activities.
I hope that with the attention and efforts of the whole society, the myopia rate of our children will further decline.
Tips
1. Pay attention to eye hygiene and scientific eye protection
2. Reduce the burden of schoolwork and enhance outdoor physical exercise
3. Pay attention to genetic factors, but also pay attention to the protection of the day after tomorrow
