Myopia

Myopia is also called shortsightedness, because this kind of eyes can only see near and far vision. When in a resting state, the parallel light from infinity, after being refracted by the eye's refractive system, gathers focus before the retina, and an unclear image is formed on the retina. Far vision is significantly reduced, but near vision is still normal. According to dynamic refractive index: false myopia, true myopia, mixed myopia. According to the nature of the lesion: simple myopia, pathological myopia, progressive myopia. Divided by refractive components: curvature myopia, refractive myopia, axial myopia.
