Abstract: increasing the time of outdoor activities has a clear protective effect on the occurrence and development of juvenile myopia. Therefore, parents must take their children outdoors. The more outdoor activities, the less likely it is to develop myopia. For children who want to prevent myopia, outdoor activities should be at least 2 hours a day, and 3 hours is better.
1. Juvenile myopia
according to the survey data, it is estimated that China’s myopia population will exceed 700 million by 2020, especially children’s myopia is becoming more and more serious and the trend of younger age is obvious. Myopia prevention and treatment is urgent!
when it comes to why children are short-sighted, the first reaction of parents is to play with mobile phones and watch TV. Indeed, this is the most common cause of children’s myopia. However, this is not the only cause of children’s myopia. There are many causes of myopia. I believe 90% of parents don’t know. Let’s have a look!
1. Lack of sufficient outdoor exercise time
research shows that increasing outdoor activity time has a clear protective effect on the occurrence and development of juvenile myopia. Therefore, parents must take their children outdoors. The more outdoor activities, the less likely it is to develop myopia. For children who want to prevent myopia, outdoor activities should be at least 2 hours a day, and 3 hours is better.
2. The eye environment is unhealthy.
read in places where the light is too bright, too dark, glare and reflective. If the light is too strong, it will cause strong reflection, stimulate the eyes, make the eyes uncomfortable and make it difficult to see the font; If the light is too weak, the written lighting is insufficient, and the eyes cannot clearly see the font, the head will move forward and get close to the book. Both of the above conditions will lead to eye fatigue, excessive adjustment or spasm and form myopia.
3. Incorrect eye posture
children have poor self-control and do not pay attention to correct reading and writing posture. If you often read and write too close, the adjustment of your eyes will be extremely tense, which can form myopia.
4. Children with insufficient sleep time are prone to myopia. In children’s rapid growth and development period, especially when they are 7-9 years old and 12-14 years old, if they sleep less, they will cause myopia in some children.
5. Parental myopia inheritance
children whose one or both parents are highly myopic have a higher risk of myopia than ordinary children. Experts say that genetic factors play an important role in the occurrence and development of myopia. If both husband and wife are highly myopic, the probability of children’s myopia is more than 80%.
6. No complete visual development files have been established.
children over 3 years old are recommended to come to a professional ophthalmic hospital for ophthalmic examination 1-2 times a year to establish a complete visual development file. Timely understand the child’s vision and find out the changes of vision. Once the child’s refractive state changes, timely intervention and treatment are needed.
