Introduction
On an eye examination report, R usually indicates the right eye, and L typically indicates the left eye; S stands for spherical lens, where "+" and "-" denote hyperopia (farsightedness) or myopia (nearsightedness), respectively; C represents cylindrical lens, A refers to the axis of astigmatism, and PD denotes pupillary distance. Visual acuity is primarily tested using a standard eye chart, with measurements recorded either by decimal notation or the five-point scale method.
In general, a vision examination report focuses on two key values—refractive power and visual acuity—which can effectively determine whether there is any vision abnormality. The specific analysis is as follows:
On a vision examination report, "R" typically stands for the right eye, and "L" for the left eye; "S" represents the spherical lens, with "+" indicating hyperopia (farsightedness) and "-" indicating myopia (nearsightedness); "C" refers to the cylindrical lens, "A" represents the axis of astigmatism, and "PD" indicates pupillary distance. Visual acuity is primarily tested using a standard eye chart, with measurements recorded either by decimal notation or the 5-point scale. Normal vision is defined as 1.0 in decimal notation or 5.0 on the 5-point scale. Values below these indicate reduced vision. Normal refractive power includes measurements for myopia, hyperopia, and astigmatism. For adults, normal visual acuity is 1.0 or higher. However, in children and adolescents, normal visual acuity often does not reach 1.0, and should be assessed according to age.
If any abnormalities are detected, it is recommended to consult a doctor promptly and take appropriate treatment measures.
