Introduction: Considering the few published population-based studies about vocational driver vision, this study conducted for determining prevalence of color vision deficiencies and refractive errors in vocational drivers applying for a health card in Shahrood.
Methods and Materials: In this cross-sectional study, among the vocational drivers of Semnan province who were registered to obtain/renew health card at the occupational health center, 2856 eligible person included in the study. In all candidates, refractive errors and visual acuity (with and without correction) measured, and color vision test evaluated with Ishihara pseudo-isochromatic plates.
Results: Among 2856 participants with an average of 38.09 ± 7.2 years old (range of 23 to 61 years), 197 participants (6.89% of population) had color vision disorders. 108 participants (3.78%) had deuteranomaly, 33 person (1.15 %) had protanomaly, 31 person (1.1 %) had deuteranopia, and 23 person (0.8 %) had protanopia and 2 persons (0.07%) were total color blind. The average of visual acuity of the right eye without correction was 0.81 ± 0.18 decimal and the left eye was 0.78 ± 0.17 decimal. These are reported 0.99 ± 0.01 and 0.99 ± 0.02 for right and left eyes (respectively) with correction. The prevalence of myopia and hyperopia among color blinds 18 and 9.7 percent and in the entire studied population 21.7 and 10.8 percent (respectively) obtained.
Conclusion: Considering the importance of vision health in study group and considering that vocational drivers have reached these stages after obtaining all related driving licenses, however, their prevalence of CVD and refractive errors are considerable.
