A binary and multivariate logistic regression model was fitted and associated factors of the outcome variable.

Results: The prevalence of near visual impairment was 64.6%, with a Confidence Interval (CI) of 60.3%-68.4%. Near visual impairment was significantly associated with age ≥ 35 years (Avascular Outer Retina (AOR): 4.90 at 95% CI: 3.15, 7.65), having prolonged years of teaching experience (AOR: 3.29 at 95% CI: 1.70, 4.62), having a history of ocular surgery (AOR: 1.96 at 95% CI: 1.10, 4.62), smokers (AOR: 2.21 at 95% CI: 1.22, 4.07), history of ocular trauma (AOR: 1.80 at 95% CI:1.11,3.18 and uncorrected refractive error (AOR:2.01 at 95%CI:1.13,4.03).
