Introduction
To analyze a vision examination report, first distinguish between the left and right eyes, then determine whether the values represent uncorrected (naked eye) vision or corrected vision. For uncorrected visual acuity, simply refer to the numerical values; for corrected vision, you should also examine the values for spherical correction (sphere), astigmatism (cylinder), and axis. Vision examination reports are crucial for assessing eye conditions and prescribing eyeglasses. If you require such an evaluation, it is generally recommended to go directly to a正规 hospital to ensure accuracy and avoid errors in results.

To analyze a vision examination report, first distinguish between the right and left eyes, then determine whether it refers to uncorrected vision or corrected vision. For uncorrected vision, simply check the numerical value; for corrected vision, you must also examine the values for spherical power, astigmatism, and axis. The detailed analysis is as follows:

Vision examination reports include both uncorrected and corrected vision. "R" stands for the right eye, and "L" for the left eye. Uncorrected vision may be expressed in two ways: one ranging from 0.1 to 1.5, and the other from 4.0 to 5.2. For uncorrected vision, simply read the numerical value after identifying the correct eye. For corrected vision, you need to review the eyeglass prescription. "S" represents the spherical power, where a "+" in the S column indicates hyperopia (farsightedness), and a "-" indicates myopia (nearsightedness). Multiply the number following the sign by 100 to obtain the actual refractive power. "C" stands for cylindrical power, which indicates the astigmatism degree. "A" represents the axis of astigmatism.

The vision examination report is crucial for assessing eye conditions and accurately prescribing glasses. If you require such services, it's generally recommended to visit a reputable hospital to ensure accurate results and avoid errors.
