ABSTRACT

[Purpose] The purpose of this study was to analyze visual acuity and health behaviors of elementary, middle and high school students with unaided or corrected vision of 0.3 or less variables. [Method] Using IBM SPSS Statistics 23.0, the national health examination sample survey data of 1,733 students with unaided vision and 161 students with corrected vision of 0.3 or less were analyzed. [Results] In students with unaided vision of 0.3 or less, there was a significant difference in left-eye vision by gender but there were no significant differences in right eye vision and the difference value of visual acuity between both eyes. Also, there were significant differences in both eye vision and the difference value of visual acuity between both eyes by school level but there was no significant difference by city size. In students with unaided vision of 0.3 or less, there were no significant differences in left and right eye vision and the difference value of visual acuity between both eyes by gender. However, there were significant differences in both eye vision by school level, and there were significant differences in both eye vision and the difference value of visual acuity between both eyes by city size. Based on the health indicators of the Ministry of Education, it was confirmed that the students needed to improve their health behavior according to overall vision-related health variables such as nutrition and eating habits, physical activities, the Internet and games. [Conclusion] Students with vision below 0.3 require a vision health promotion program that considers general characteristic variables (gender, school level, city size) and vision-related health variables to maintain vision and prevent further vision loss. In addition, it is necessary to check whether the students' vision status is unaided vision or corrective vision, and to pay attention to the difference in vision between the two eyes in consideration of the importance of anisometropia.
