Abstract
|
|
|
Purpose: The current method used, tests the uncorrected visual acuity and determines the accuracy and consistency of the results. The study will also analyze the criteria for presenting accurate and consistent uncorrected visual acuity values.
Methods: We conducted a questionnaire survey of the uncorrected visual acuity test at 83 optical shops in the Seoul and Gyeonggi region, as well as an uncorrected visual acuity test from randomly selected 13 university students in the Gyeonggi region.
Results: The results of uncorrected visual acuity from the conventional method became inconsistent and inaccurate, depending on the examination method and the characteristics of the examinee. The conversion table of calibration refractive power and uncorrected visual acuity was presented for the improvement of the test value accuracy of uncorrected visual acuity.
Conclusions: Optometrists should check the corrected refractive power accurately to improve fairness and accuracy, and use the resulting value after converting it to the uncorrected visual acuity value as an important standard.
