Abstract

The objectives of this quasi-experimental study were to determine the effects of eye care program on the levels of eye care by primary school teachers and students in Songkhla Province. The subjects of the study were 200 primary school teachers and students. The subject size was calculated with Power Analysis. The instruments of the study were eye-screening equipment, vision recording books, a computer assisted instruction (CAI) progtam on eye care with an average efficiency between 80/80, and an eye care ability test. The content of the eye care lessons was tested to determine content validity of the test by three experts consisting of an ophthalmologist and two family practical nurses ; the Kuder-Richardson coefficient obtained was 0.81. The data were analyzed in frequency, percentage, mean, standard deviation, paired t-test, and independent t-test. The results were as follows:The eye examination was carried out on the primary school students who were the subjects of the test by their teachers who had learned about eye care from the CAI lessons using a Snellen's chart. It was found that 94.0 percent of the students in the experimental and the control groups had normal vision and 6.0 percent of the subjects had a vision problem.When comparing the means, standard deviation, the score of eye care ability of the teachers and students in the experimental group and the control group, it was found that the average score for the level of eye care ability of the experimental group was higher than that of the control group. When tested statistically, it was found that there was a statistically significant difference at 0.05 between the average score of eye care ability of the teachers and students in the experimental group and the control group. The teachers had potential in helping children in terms of eye care by testing their students' vision to find out whether their vision is normal or not before it is too late. Therefore, teachers can do the job that is usually done by a school health team at a low cost which is another good access to health service in school.
