Purpose: In this study, we divided into three investigated groups. The A group is the lower elementary school(30), The B group is the high elementary school(30), The C group is the junior high school(30), The D group is the high school students(30). the myopia progression have been compared with each group and most variable terms have been investigated.
Methods: We have analyzed the refraction inspection record for corrected vision which is 120 students(men 60, women 60) visited optical shop for more than three times in three years.
Results:
1. The distribution of spherical equivalent power with ages : A group -2.32D, B group -2.57D, C group -3.44D, D group -3.95D.
2. On a monthly variation of spherical equivalent power : -0.06D(A), 0.055D(B), -0.055D(C), -0.045D(D) in men, and-0.08D(A), -0.06D(B), -0.05D(C), -0.025D(D) in women.
Conslusion: After due considering monthly variation and suppose that the variation and suppose that the variating times of spectacles degrees were time of refracting inspection. the result : 3.7 month for A group, 5.1 month for B group, 4.7 month for C group, 8.5 month for D group.
