“Spherical equivalent by age of subject (n = 218)”. Caption: Scatterplot of age and spherical equivalent for subjective refraction. In the study population there was weak association between age and subjective refractive error (r = 0.335, p < 0.001). Regression equation: Spherical equivalent = −3.03 + 0.054 Age; 50 % confidence interval: 1.96 D
