Abstract
A study of the visual status of students in the 7th grade in Taipei City began in November 1986. Data on 1,620 students from 39 schools were collected in March 1987. 40 classes were selected as samples through the procedures of systematic cluster sampling. With the assistance of the Education Department, investigation went on schedule in all schools. Thus, the complete rate reaches 96.14%.
A self-devloped questionnarie verified by professionals and Snellen's Vision Chart installed in a lighted box were applied as the research instruments. Related data were then collected bt trained investigators following the same criteria and steps.
The rate of visual defects in the subjects is 62.78%. Students who are female, classified as high in SES, born in families with fewer siblings, and ranked high in IQ percentile show higher rate of visual defects than other students. Among students with defective vision, 10.05% of them perceived themselves as having normal vision; 45.14% never have their defects corrected; only 18.49% have their defects corrected to normal.
Being busy is the main reason given by parents and children (49.64% and 29.93%) for having not corrected the visual defects. Students with defective vision receive higher scores in knowledge test than students with normal vision. However, both groups receive low scores in behavioral evaluation through the difference is small. As "knowledge" and "attitude" variables are not significantly related to the variable "behavior", it is suggested that future efforts be focussed on the following activities which are behavior promotion oriented to improve the visual health of school children in general and to encourage the correction of defects if any: (1) conducting visual tests and health education activities periodically; (2) improving the environment of study; and (3) establishing special clinics for visual protection and correction. Beharioral techniques instead of propaganda should be applied in the visual promotion programs in the future.
