How to read the prescription values on an eye examination report
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.
