Although visual impairment of drivers is a very important risk factor for car accident, a few published papers have explored this issue in Iran. This study aims to evaluate the visual fitness of public vehicle drivers in Kerman province, southeast of Iran.
A total of 4,003 public vehicle drivers were examined by one ophthalmologist for visual fitness in Kerman province between January 2009 and June 2010. Data are presented as Mean±SD or percentage, and with 95% confidence intervals (CIs). Pearson Chi-square and McNemmar tests along with crude odds ratio (OR) were used to compare vision deficit between groups.
Almost 361 drivers (9.0%; 95% CI: 8.1-9.9) had insufficient vision to drive public vehicles before the refractive errors (RE) correction and this number, was reduced to 68 drivers (1.7%; 95% CI: 1.3-2.1) after the correction. A number of them including 200 drivers (5.0%; 95% CI: 4.3-5.7) had insufficient vision to drive personal vehicles before the correction and this was reduced to 30 thereafter (0.8%; 95% CI: 0.5-1.0). We also found out that the vision status got worse with aging, and RE was the most prevalent cause of sight defects.
It seems that visual fitness of public vehicle drivers is a point of real concerns which might somewhat explain the high rate of car accidents in Iran.
尽管驾驶员视力受损是交通事故的一个非常重要的风险因素，但在伊朗，很少有已发表的论文探讨过这个问题。本研究旨在评估伊朗东南部克尔曼省公共车辆驾驶员的视力健康状况。
2009年1月至2010年6月期间，一名眼科医生对克尔曼省总共4003名公共车辆驾驶员进行了视力健康检查。数据以均值±标准差或百分比表示，并带有95%置信区间（CI）。使用Pearson卡方检验、McNemar检验以及粗比值比（OR）来比较各组之间的视力缺陷情况。
在屈光不正（RE）矫正前，近361名驾驶员（9.0%；95%CI：8.1 - 9.9）视力不足以驾驶公共车辆，矫正后这一数字降至68名驾驶员（1.7%；95%CI：1.3 - 2.1）。其中包括200名驾驶员（5.0%；95%CI：4.3 - 5.7）在矫正前视力不足以驾驶私家车，之后降至30名（0.8%；95%CI：0.5 - 1.0）。我们还发现视力状况随着年龄增长而变差，屈光不正是视力缺陷最常见的原因。
公共车辆驾驶员的视力健康似乎是一个真正值得关注的问题，这在一定程度上可能解释了伊朗交通事故发生率较高的原因。
