Until now, the study of eye refractive error examination for high school students are a few report that in Korea. In particular, there is few report about the visual power for same group during several years. We compared the study of refractive error done this year with that reported three years ago at the same high school. From the these data, the distribution of ammetropia was investigated. The study of refractive error for high school students was also compared with those reported before for the Adults and the middle school student. When the visual power is refered to spherical equivalent, the 36 % of the whole students examined above had emmetropia and the other part of them fumed out to be ammetropia which is classify to 60.6 % belonged to myopia and 4.4 % belonged to hyperpia. The ratio of myopia for this year students is increased in comparition with the students in 1995. The ratio of emmetropia for this year students is 7.4 % higher, and the ratio of myopia for this year students is 4 % higher, but the ratio of hyperopia is very lower than that for the adults in 1997. In the kind of refractive error, it is classified that a simple myopia is shown to highest ratio as a 28.6 % of 1212 eyes examined, a compound myopic astigmatism to the next high rartio as a 22.4 %, a simple myopic astigmatism as 14.4 %, a simple hyperopic astigmatism as 3.1 %, a mixed astigmatism as a 1.7 %, a simple astigmatism as 1.2%, a compound hyperopic astigmatism as 1.2%, respectively. The percentage of an astigmatism is a 76.7 % of total eyes examined if Cyl-0.25 Dptr is included to an astigmatism. On the other hand, The percentage of an astigmatism is a 45.6 % of total eyes examined if Cyl-0.25 Dptr is excluded to an astigmatism. In the kind of astigmatism, the number of students had an astigmatism with the rule is about 4.5 times than that of astigmatism against the rule. From the result of comparition the right eye with the left eye, the right eye of the students had more a myopic refractive error than the left eye, which is same as adults` case, there is no difference in a refractive error between the boy students and the girl students
