How many degrees of myopia is 0.6, need to be dilated optometry to know, the normal standard of vision is 1.0 or 5.0, vision 0.6 is considered to be a kind of low vision, and the cause of low vision may also be myopia, hyperopia and astigmatism and other causes. 1. Myopia: The cause of myopia is the elongation of the eye axis, which occurs mainly because of the signals that lead to myopia overgrowth. It is currently believed that a combination of genetic and environmental factors cause an increase in the refractive power of the lens or an elongation of the eye axis. 2. Hyperopia: The principle of hyperopia is that parallel light rays from a distance are refracted by the refractive system of the eye and then focused behind the retina instead of on it. For example, children under 6 years of age with underdeveloped eyeballs, flat corneas, aphakic eyes or dislocated lenses show high hyperopia. 3. Astigmatism: refers to the refraction of light rays into the eye in the refractive system, will form two front and back of the focal line, which is a kind of non-planar astigmatism, astigmatism can be caused by the refractive system of the eye refractive media of any one of the abnormalities can be categorized into congenital astigmatism and acquired astigmatism. Therefore, 0.6 is how many degrees of myopia still need to go to a professional hospital for optometry, according to the results of the doctor’s judgment and then standardized treatment.
