14세에서 19세까지의 중 고등학생 1750안(875명)을 대상으로 cross cylinder lens와 적 녹 검사를 이용하여 교정후 조절력검사를 실시하여 다음과 같은 결과를 얻었다. Cross cylinder lens법을 사용하여 교정후 조절력검사를 측정한 결과 0 Dptr에서는 33%의 오차범위가 나타났고 -0.25 Dptr에서는 58%로 측정되었다. -0.75 Dptr에서는 1%의 오차 범위가 측정되었고 -1.00 Dptr에서는 오차가 측정되지 않았다. Cross cylinder lends법을 이용한 정밀구면굴절력의 오차범위는 0 Dptr에서 -0.25 Dptr까지 1%에 달하는 정밀측정 오차가 발생되었다. 적 녹검사를 이용한 교정후 조절력검사는 0 Dptr에서 -.025 Dptr에서 75%의 비율이 측정되었고 -0.50 Dptr에서는 20%가 측정되었다. 이 측정결과 Cross cylinder lens를 이용한 측정이 적 녹검사측정보다 더 세밀한 측정결과를 나타내었다.

In this study, It obtained results that the exact spherical diopter to practice test by using Cross cyliner lens and Red Green Card method. In the test used to the 1750 eyes of middle and high school students. The results was as follows ; 1. Using Cross cylinder lens method, I tested a exact spherical diopter after accommodation. At -0.25 Dptr the ratio of spherical Dptr error limits were measured as 58% and at -0.75 Dptr they were oppeared as 1%, at -1.00 Dptr they are not measured. In this method, the error limits of exact spherical Dptr was 91% from 0 Dptr to -0.25 Dptr. 2. Using Red Green Card method, they were measured as 45% at -0.25 Dptr. and measured as 20% at -0.50 Dptr. From the result of these test, Cross cylinder lens method was a better detailed method than Red Green Card method.
