Visual impairment due to refractive errors and color vision deficiency (CVD) can affect the visual abilities of workers in workplace. Identifying the prevalence of common visual problems helps us to prevent and treat occupational ocular problems.This study was conducted on 2600 males referring from companies for a routine medical exam to Occupational Medicine Center. In all subjects, visual acuity and refraction were measured. Assessment of color vision was performed by Ishihara color test. In present study, right eyes of subjects were selected to statistical analysis.The mean spherical equivalent was -0.19 ± 1.39 diopter with a range of -11.00 to +10.00 diopter. Whereas 71% of persons were emmetropic, 20% and 9% of them were myopic and hypermetropic, respectively. From a total subjects, 164 of them had CVD with prevalence of color blindness of 6.3%. In comparison with normal subjects, CVD had no significant effect on refractive findings of our subjects (P > .05).Our data present the prevalence of refractive errors and color blindness among Iranian industry-workers. Compared with other studies, our subjects have a lower prevalence of refractive errors, and similar rate of prevalence of color blindness.
视力障碍由于屈光不正和色觉缺陷（CVD）会影响工作场所工人的视觉能力。确定常见视觉问题的患病率有助于我们预防和治疗职业性眼部问题。本研究对 2600 名男性进行了研究，这些男性是从公司为常规体检到职业医学中心就诊的。在所有受试者中，均测量了视力和屈光度。通过 Ishihara 色觉试验评估了色觉。在本研究中，选择了受试者的右眼进行统计分析。平均等效球镜为-0.19±1.39 屈光度，范围为-11.00 至+10.00 屈光度。而 71%的人是正视眼，20%和 9%的人分别是近视和远视。在所有受试者中，有 164 人有色觉缺陷，色盲患病率为 6.3%。与正常受试者相比，CVD 对我们受试者的屈光结果没有显著影响（P>.05）。我们的数据显示了伊朗工业工人屈光不正和色盲的患病率。与其他研究相比，我们的受试者屈光不正的患病率较低，而色盲的患病率相似。
