Abstract: from the age of 3 to 6, a comprehensive optometry is performed once a year and a refractive development file is established. The refractive development file is to make a refractive development evaluation for the child’s eyes to see if the child has myopia, hyperopia and astigmatism. What are the causes of
1. Genetic factors:
parents are children with high myopia, and the risk of myopia is higher than that of ordinary children. If both husband and wife are highly myopic, the probability of children’s myopia is as high as 85%.
2. Environmental factors:
lack natural light exposure, reading in places where the light is too bright, too dark, glare and reflective, reading in a bumpy environment, and using eyes in an inappropriate environment.
3. Behavioral factors:
too little outdoor sports, too much close eye use, long-time reading and playing with mobile phones, incorrect writing posture, less sleep time and other behaviors will increase the risk of myopia.
prevent children’s myopia. You should do these
1 Increasing outdoor exercise time
research shows that increasing outdoor activities can effectively reduce the incidence rate of myopia. Therefore, for children who want to prevent myopia, the outdoor activity time is at least 2 hours, and 3 hours is better.
2. Develop good eye habits
pay attention to the correct posture when reading and writing. Don’t read or use your mobile phone when walking or riding. Don’t use your eyes for a long time and rest for 10 minutes every 50 minutes or so. Ensure adequate sleep time.
3. Establish the archives of ocular refractive development
. From the age of 3 to 6, do a comprehensive optometry every year and establish the archives of refractive development. The refractive development file is to make a refractive development evaluation for the child’s eyes to see if the child has myopia, hyperopia and astigmatism. Children before the age of six or seven are low-grade hyperopia, and their refractive state will change with the development of the eyeball, so our common myopia can be predicted in advance. In order to understand the refractive changes of children in detail, find abnormal refractive development in time, take children for refractive examination regularly, and establish perfect refractive development files.
4. Cloud clip
cloud clip is a device that can objectively record the relevant factors of risk factors of myopia. In the past half century, the incidence rate of myopia has increased dramatically, which is largely caused by environmental factors, such as close work and outdoor activities. The cloud clip can record the above environmental factors comprehensively and objectively, which provides an effective basis for accurate prediction and prevention of myopia. The monitoring frequency of cloud clip is up to 10 times per second, which can dynamically monitor children’s eye use in real time, and remind children or their parents to adjust bad eye use to prevent or control myopia.
