In this study, the variation of astigmatism axis according to the age was studied 4277 eyes of healthy eyes. The refractive errors were measured by objective and subjective refraction. The astigmatism among the total eyes was 76.5%. With-the-rule, against-the-rule and oblique astigmatism were 51.4%, 31.7% and 16.9%, respectively. The frequency of with-the-rule was the highest and against-the-rule was the lowest of all the astigmatism in the refractive error. In relation to the age and astigmatism, the with-the-rule was 68.3% in the 10`s age group which was the highest among the astigmatism and the against-the-rule was 10.3% in the 50`s age group and upward which was the lowest among the astigmatism. The difference in the with-the-rule and against-the-rule ratio was a little in the 30`s age group. As they aged, the tendency of the with-the-rule was increased between 10`s and 20`s age group continually. And the tendency of the against-the rule was increased between 30`s and 50`s age group and upward. There was a decrease in with-the-rule and an increase in against-the-rule, with the age increase. The oblique astigmatism relationship to age could not be determined.
