Naked eye vision 4.8 is equivalent to 0.6 vision, standard vision table 0.6 or so vision, if myopia is equivalent to about 100 degrees of myopia, if astigmatism, equivalent to about 150-200 degrees of astigmatism, if farsightedness, equivalent to more than 200 degrees of farsightedness, vision and refractive state do not exactly match, the same vision may be different people refractive error is very different. In addition, myopia and astigmatism or farsightedness and astigmatism often appear together, but myopia and farsightedness do not appear at the same time, so it is impossible to determine what kind of refractive state it is just by looking at the visual acuity, you need to go to the hospital to do computerized optometry, and then combine the visual acuity to make a judgment. Vision 4.8 is generally a mild vision loss, and it is recommended to wear glasses early to slow down the development of myopia.
