METHODS: A cross-sectional type study was conducted between November 2004 and September 2006 in 200 driver and 200 non-driver persons. A complete ophthalmologic examination was performed, including visual acuity, and dilated examination of the posterior segment. We used the auto refractometer for determining refractive errors. RESULTS: According to eye examination results, the prevalence of the refractive error was 21.5% and 31.3% in study and control groups respectively (P<0.05). The most common type of refraction error in the study group was myopic astigmatism (8.3%) while in the control group simple myopia (12.8%). Prevalence of dyschromatopsia in the rivers, control group and total group was 2.2%, 2.8% and 2.6% respectively. CONCLUSION: A considerably high number of drivers are in lack of optimal visual acuity. Refraction errors in drivers may impair the traffic security.en10.3980/j.issn.2222-3959.2011.03.23info:eu-repo/semantics/openAccessrefractive errormyopiahypermetropiacolour blindnessPrevalence of refraction errors and color blindness in heavy vehicle driversArticle43322319225536712-s2.0-84897672573Q2WOS:000291921300023Q4
