Abstract: simple myopia generally occurs in school age. The degree of myopia is below 600 degrees. There is generally no obvious change in the fundus of the eye. The vision can be corrected to normal with appropriate lenses. Generally, the degree tends to be stable after the body matures (after the age of 20)., Myopia can be divided into pseudomyopia, true myopia and mixed myopia. Pseudomyopia is more common. How many degrees is pseudomyopia? Now, the ophthalmologists of Qingdao Oriental ophthalmology Research Institute will give you a specific introduction, hoping to help you., Myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light is bent through the refractive system of the eye without adjustment. So myopia can’t see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent to the eye, the focus will move backward. When the target moves closer to a point in front of you. The closer this point is to the eye, the deeper the degree of myopia., Simple myopia generally occurs in school age. The degree of myopia is below 600 degrees. There is generally no obvious change in the fundus of the eye. The vision can be corrected to normal with appropriate lenses. Generally, the degree tends to be stable after the body matures (after the age of 20). Simple myopia is mainly seen in adolescents and children. Its basic characteristics are that it occurs and develops during the growth and development of adolescents; It deepens slowly and becomes basically static and stable in adulthood. Unless particularly effective corrective treatment measures are taken, the whole process is irreversible; Low far vision, normal near vision and other visual functions; Low and normal far vision can be corrected ideally; Myopic refraction is mostly low or moderate; Pathological myopia usually does not develop., Progressive myopia generally does not develop until the age of 20, but a few myopia continue to develop, especially in adulthood. Myopia continues to worsen, the axis of the eye continues to lengthen, and the diopter increases year by year, even more than 2000D. This kind of myopia is called progressive myopia, malignant myopia and degenerative myopia. Progressive myopia goes beyond the scope of ametropia to a certain extent, and will eventually lead to a series of pathological changes of the whole eyeball. Such as early degenerative changes, decreased vision, mild degenerative changes of vitreous, etc.,

progressive myopia generally does not develop until the age of 20, but a few myopia always develop, especially in adulthood, myopia continues to aggravate, the axis of the eye continues to extend, and the diopter increases year by year, even more than 2000D. This kind of myopia is called progressive myopia, malignant myopia and metamorphic myopia. Progressive myopia goes beyond the scope of ametropia to a certain extent, and will eventually lead to a series of pathological changes of the whole eyeball. Such as early degenerative changes, decreased vision, mild degenerative changes of vitreous, etc.
