Abstract: 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.
which kind of myopia will inherit
the common myopia can be divided into mild myopia (within 300 degrees), moderate myopia (300 to 600 degrees) and high myopia (above 600 degrees).
High myopia refers to myopia with high diopter and significantly prolonged ocular axis. Due to the continuous growth of ocular axis, the retina of patients with high myopia can be pulled, which can lead to retinal tear and retinal detachment. At the same time, the incidence of retinal hemorrhage, macular lesions, posterior scleral staphyloma, glaucoma and cataract will also double, and the blindness rate of these complications is high. Therefore, high myopia is also one of the common causes of blindness in clinic. Experts say that if parents are highly myopic, the incidence of myopia in children is likely to reach more than 80%. Even if a child is not myopia at birth, he will become a carrier of myopia gene. Once affected by the environment, he may develop myopia.
prevent children from myopia
. 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.
establish the file of refractive development of the eye
refractive development file is to evaluate the refractive development of the child’s eyes to see if the child has myopia, hyperopia and astigmatism. Every child is born with “hyperopia”. With the increase of age and the cultivation of the habit of using eyes at close range, he slowly develops from “hyperopia” to “myopia”. Therefore, through the early examination of eye axis, corneal curvature and visual acuity, preventive measures can be taken to protect the child’s “hyperopia reserve” from being consumed and effectively prevent the occurrence and development of myopia.
