The role of interocular differences simulated by filters (fog filter and Bangerter foil) on visual and driving performance in alcohol users was assessed. We found that the binocular visual function deteriorates significantly in terms of contrast sensitivity (from 6 to 18 cpd). Additionally, driving performance is significantly impaired under these conditions as evidenced by increased mean speed, standard deviation of the lateral position, distance traveled outside the lane, reaction time and number of collisions. Furthermore, we found that interocular differences due to intraocular scattering and straylight are directly related to an overall reduction in visual and driving performance. This provided a comprehensive perspective from which to understand the relationship between binocular visual function, interocular differences, and driving performance. In practice, our findings contribute to the understanding of the importance of limiting interocular differences, which can be common among presbyopes corrected using the monovision technique, as well as in cases of cataract or other ocular pathology affecting only one eye, or even in cases of cataract surgery of the first eye. These interocular differences can have an adverse impact on road safety, especially when combined with moderate alcohol consumption.
我们评估了滤光片（雾镜和邦格特箔）模拟的双眼视差对饮酒者视觉和驾驶表现的影响。我们发现，双眼视觉功能在对比敏感度方面显著恶化（从 6 到 18 cpd）。此外，在这些条件下，驾驶性能显著受损，表现在平均速度增加、横向位置标准差增大、偏离车道行驶的距离增加、反应时间延长和碰撞次数增加。此外，我们发现由于眼内散射和杂散光引起的双眼视差与视觉和驾驶表现的整体下降直接相关。这提供了一个全面的视角，有助于理解双眼视觉功能、双眼视差和驾驶表现之间的关系。在实践中，我们的发现有助于理解限制双眼视差的重要性，这在使用单视技术矫正的远视患者中很常见，也适用于仅影响一只眼的白内障或其他眼部病变的情况，甚至在第一只眼接受白内障手术后也是如此。这些双眼视差会对道路安全产生不利影响，尤其是在与中度饮酒相结合的情况下。
