One of the main risk factors involved in increasing driving accidents at night is due to the veiling luminance of the car's headlights reducing the contrast of images in the retina and, thus, reducing the visual performance of drivers. The aim of this study is to investigate the veiling luminance caused by the headlights of the best-selling vehicles in Iran. Using the Stiles-Holiday disability glare equation, the veiling luminance of headlights of common vehicles at distances of 10-100 m for both high-beam and low-beam modes of oncoming vehicles was measured on a road for healthy (young, middle-aged and older) drivers. Under high-beam illumination, as the cars approached each other, the average illuminance of the car headlights gradually increased. Moreover, age had a significant impact on the veiling luminance. This study also showed that, in same-age groups, the Samand Souren and Peugeot Pars cars had the highest and lowest mean veiling luminance, respectively. The findings showed that the illuminance (at large distances between two cars) and the angle between the source of glare and the eyes of drivers (as two cars approach to each other) have a dominant influence on the disability glare.
夜间驾驶事故增加的一个主要风险因素是由于汽车前照灯的光幕亮度降低了视网膜图像的对比度，从而降低了驾驶员的视觉表现。本研究旨在调查伊朗最畅销车辆的前照灯产生的光幕亮度。使用 Stiles-Holiday 障碍眩光方程，在道路上测量了健康（年轻、中年和老年）驾驶员在 10-100 米距离处迎面而来的车辆的远光灯和近光灯模式下常见车辆前照灯的光幕亮度。在远光灯照明下，随着汽车相互靠近，汽车前照灯的平均照度逐渐增加。此外，年龄对光幕亮度有显著影响。本研究还表明，在同年龄组中，Samand Souren 和 Peugeot Pars 汽车的平均光幕亮度分别最高和最低。研究结果表明，照度（在两辆车之间的大距离处）和眩光源与驾驶员眼睛之间的角度（当两辆车相互靠近时）对障碍眩光有主导影响。
