ASSESSMENT OF SEX VARIATION ON VISUAL ACUITY AND COLOR PERCEPTION AMONG STUDENTS OF BSC HUMAN PHYSIOLOGY OF SA’ADU ZUNGUR UNIVERSITY, GADAU
Abstract
This study assessed sex variation in visual acuity and color perception among BSc Human Physiology students of Sa’adu Zungur University, Gadau. A total of 210 students participated, comprising 110 males (52.4%) and 100 females (47.6%). Visual acuity was measured using standard Snellen charts, while color perception was assessed with Ishihara plates. Results showed that 71.4% of students had normal visual acuity (6/6), while 20% exhibited mild impairment, and only 8.6% presented with moderate to severe impairments. An independent t-test revealed no significant difference in visual acuity between male and female students (p > 0.05). In terms of color perception, 92.4% of students demonstrated normal vision, with 7.6% showing mild to moderate deficiencies and no cases of severe color blindness. Chi-square analysis indicated no significant sex difference in color perception (p > 0.05). The findings suggest that students generally have good visual functions, with no notable variation between sexes. Early screening is recommended for those with mild impairments to prevent progression.
