Abstract

Objective To understand the occurrence status of poor eyesight, dry eye in primary and middle school students and its correlation. Methods School was used as sampling unit, and 300 cases of primary and middle school students were selected by stratified cluster random sampling. Results The poor vision prevalence rate was 48.0%, the prevalence rate of dry eye was 6.7%, the rate of poor eyesight with the grade increasing trend was gradually increased, and the incidence of women was higher than men.The indicators of the observation group[BUT(tear)(6.4±2.4)s, SIt(Schirmer test)(10.4±4.9)mm, FL(corneal fluorescein staining)(3.1+ 0.9)] were significantly better than the control group[BUT(13.7±3.3)s, SIt(15.3±5.4)mm, FL(1.8±1.0)], there were statistically significant differences between the two groups(t=12.6, 4.7, -6.8, all P<0.05). Conclusion Students of poor eyesight and dry eye is high prevalence, and the poor eyesight is a dry eye prone group, right eye should be a reasonable way of life to students.
