视力测试结果怎么看

Vision test results typically include information on the visual condition of the left and right eyes, spherical power, cylindrical power, and pupillary distance. Spherical power indicates the degree of myopia or hyperopia, with a negative sign representing myopia and a positive sign representing hyperopia; cylindrical power indicates the degree of astigmatism; pupillary distance is an important reference for eyeglass fitting. If the vision test results fall within the normal range, they are generally considered normal.
