Aim: This study compared the effect of yellow filters and corrective lenses on the academic performance of primary school children with abnormal contrast sensitivity. Study Design: The study employed quantitative study design involving the measurement of variables. Place and Duration of Study: This study was carried out in Owerri North, Imo State, Nigeria, from February, 2019 to November, 2019. Methodology: The study included 34 children between 7-12 years old in private and public schools with abnormal contrast sensitivity comprising 7-9 year-olds (64.7%); 10-12 year-olds (35.3%); Males (52.9%) and Females (47.1%). Using basic optometric procedures and Pelli-Robson contrast sensitivity chart, children with abnormal contrast sensitivity were identified for the study. Academic performance was assessed by comparing the previous midterm summative test result (pre-test) with the current midterm summative test result (post-test). Results: Paired sample t-Test showed no significant difference in academic performance of children using corrective lenses (p = .47), and those using corrective lenses with yellow filters (p = .94) respectively at 95% confidence interval. Also, children using corrective lenses compared with those using corrective lenses with yellow filters showed no significant difference (p =.57) in academic performance. Further, no significant age and gender variation in academic performance was identified (7-9 yrs: p =.38; 10-12 yrs: p =.79; Males: p=.38; Females: p =.79). Conclusion: Corrective lenses and Corrective lenses with yellow filters had no effect on academic performance of primary school children 7-12 years of age with abnormal contrast sensitivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
