CORRELATION OF PUPIL SIZE AND REFRACTIVE ERRORS OF STUDENTS IN FEDERAL COLLEGE OF SCIENCE AND TECHNOLOGY OHANSO.
Abstract
This study investigates the relationship between pupil size and refractive errors using students at Federal College of Science and Technology, Ohanso for a case study. Refractive errors, including myopia, hyperopia, and astigmatism, are common visual impairments affecting individuals worldwide. Pupil size, a dynamic parameter of the eye, plays a crucial role in regulating the amount of light entering the eye and can have a significant impact on visual acuity. The research methodology involved a comprehensive eye examination, subjective refraction, objective refraction and assessment of pupil size, among a sample of students. Data analysis was conducted to determine any statistically significant correlations between pupil size and refractive errors. Additionally the effect of pupil size on their refractive error was also tested. The results of this study revealed that there is no statistically significant relationship/correlation between pupil size and refractive error. The Analysis of Variance (ANOVA) Test was used at a 95% level of confidence to test for the significant effect/impact of pupil size on refractive error and the result from the test showed that pupil size has no significant effect on refractive error (p = 0.382 > 0.05). Further research in this area may lead to improved vision assessment and management strategies for students in educational institutions.
