Abstract
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.
