Abstract: at present, among 80 ~ 90% of adolescents with myopia, about 20 ~ 30% suffer from high myopia. Among them, 50% of myopia children may have serious vision loss. Therefore, in the future, in addition to about 8-9 million teenagers in China will have myopia, about 2-3 million people with high myopia will have the possibility of blindness.
in China, the prevalence of myopia is gradually increasing. At present, the incidence of myopia in the younger generation is 80 ~ 90%. With the growth of age, the proportion of myopia will spread in the whole adolescent population. This means that China will face 80 ~ 90% of young people with myopia in the future, and about 8 ~ 9 million people with myopia.
worse than this is that more and more teenagers develop high myopia, which will lead to obvious eye lesions and further loss of vision. These changes will increase with age.
at present, about 20 ~ 30% of 80 ~ 90% of teenagers with myopia suffer from high myopia. Among them, 50% of myopia children may have serious vision loss. Therefore, in the future, in addition to about 8-9 million teenagers in China will have myopia, about 2-3 million people with high myopia will have the possibility of blindness. This number is undoubtedly huge.
why is the number of myopia so large? This is undoubtedly inseparable from the change of people’s living habits. Due to the rapid development of information and transportation, people spend less and less time outdoors. On the contrary, they spend more and more time staring at the screen or books.
experts explained that the occurrence and development of myopia are related to long-term close eye use. The eyeballs of teenagers, in particular, are in the stage of growth and development, with strong adjustment ability and large extension of the ball wall. They play a role of adjustment and collection when using the eyes at close range for a long time, such as reading and writing, so that the internal rectus muscle exerts a certain pressure on the eyeball, and the intraocular pressure increases accordingly. With the continuous increase of the time of using the eyes at close range, The frequency and time of regulation and collection also gradually increase. The ciliary muscle and extraocular muscle are often in a high tension state. The excessive exertion of regulation will cause ciliary muscle spasm, resulting in temporary vision loss.
for myopia patients, compared with simple correction of vision, let the eyes see more clearly, and the prevention of myopia is fundamental, because myopia is irreversible. Once myopia is caused, the vision cannot be restored.
therefore, we should pay attention to our vision health from now on, especially teenagers.
