Some marketing materials for yellow-lens night-driving glasses claim that they increase nighttime road visibility and reduce oncoming headlight glare (HLG). However, there is no scientific evidence to support these claims.
To measure the association between yellow-lens glasses and the detection of pedestrians with and without an oncoming HLG, using a driving simulator equipped with a custom HLG simulator.
DESIGN, SETTING, AND PARTICIPANTS: A single-center cohort study was conducted between September 8, 2016, and October 25, 2017, at the Schepens Eye Research Institute. A total of 22 individuals participated in the study, divided into groups to determine response to a pedestrian wearing a navy blue shirt by younger individuals and, to control for participant's age and the interaction of the shirt color with the filter, response to a pedestrian wearing an orange shirt by a group of younger and older participants.
Participants drove scripted night-driving scenarios, 3 times with 3 commercially available yellow-lens glasses and once with clear-lens glasses, with the HLG simulator turned on and off. A total of 8 conditions were used for each participant.
Pedestrian detection response time.
The 22 participants who completed the study included 12 younger (mean [SD] age, 28 [7] years; 6 men) individuals who responded to a pedestrian wearing a dark navy blue shirt, as well as 6 younger (mean [SD] age, 27 [4] years; 4 men) and 4 older (mean [SD], 70 [11] years; all men) participants who responded to a pedestrian in an orange shirt. All participants had normal visual acuity (mean [SD], -0.05 [0.06] logMAR). No significant difference in response time with yellow lens was found in all experiment conditions; younger participants for dark navy blue shirt pedestrians (F1,33 = 0.59; P = .45), orange shirt pedestrians (F1,15 = 0.13; P = .72), and older participants for orange shirt pedestrians (F1,9 = 0.84; P = .38). Among all participants (n = 22), no significant main effect of yellow lenses was found (F1,63 = 0.64; P = .42). In all measuring conditions, the response times with the yellow lenses were not better than with the clear lenses. Significant main effects of HLG were found with dark navy blue shirt pedestrian condition for young participants (F1,33 = 7.34; P < .001) and with orange shirt pedestrian condition for older individuals (F1,9 = 75.32; P < .001), where the difference in response time between with and without HLG was larger for older (1.5 seconds) than younger (0.3 seconds) participants.
Using a driver simulator equipped with an HLG simulator, yellow-lens night-driving glasses did not appear to improve pedestrian detection at night or reduce the negative effects of HLG on pedestrian detection performance. These findings do not appear to support having eye care professionals advise patients to use yellow-lens night-driving glasses.
一些黄色镜片夜间驾驶眼镜的营销材料声称，它们能提高夜间道路能见度并减少迎面而来的前照灯眩光（HLG）。然而，没有科学证据支持这些说法。
使用配备定制HLG模拟器的驾驶模拟器，测量黄色镜片眼镜与有或没有迎面HLG情况下行人检测之间的关联。
设计、地点和参与者：2016年9月8日至2017年10月25日在Schepens眼科研究所进行了一项单中心队列研究。共有22人参与该研究，分为几组，以确定年轻个体对穿着藏青色衬衫行人的反应，并为控制参与者年龄以及衬衫颜色与滤光片的相互作用，一组年轻和年长参与者对穿着橙色衬衫行人的反应。
参与者驾驶预设的夜间驾驶场景，佩戴3种市售黄色镜片眼镜各进行3次，佩戴透明镜片眼镜进行1次，HLG模拟器开启和关闭。每位参与者共使用8种条件。
行人检测反应时间。
完成研究的22名参与者包括12名年轻个体（平均[标准差]年龄，28[7]岁；6名男性），他们对穿着深海军蓝衬衫的行人做出反应，以及6名年轻个体（平均[标准差]年龄，27[4]岁；4名男性）和4名年长个体（平均[标准差]，70[11]岁；均为男性），他们对穿着橙色衬衫的行人做出反应。所有参与者视力正常（平均[标准差]，-0.05[0.06]logMAR）。在所有实验条件下，黄色镜片的反应时间均未发现显著差异；年轻参与者对藏青色衬衫行人（F1,33 = 0.59；P = 0.45）、橙色衬衫行人（F1,15 = 0.13；P = 0.72），以及年长参与者对橙色衬衫行人（F1,9 = 0.84；P = 0.38）。在所有参与者（n = 22）中，未发现黄色镜片的显著主效应（F1,63 = 0.64；P = 0.42）。在所有测量条件下，黄色镜片的反应时间并不优于透明镜片。对于年轻参与者，在藏青色衬衫行人条件下发现HLG有显著主效应（F1,33 = 7.34；P < 0.001），对于年长个体，在橙色衬衫行人条件下发现HLG有显著主效应（F1,9 = 75.32；P < 0.001），其中年长参与者（1.5秒）在有和没有HLG时的反应时间差异大于年轻参与者（0.3秒）。
使用配备HLG模拟器的驾驶模拟器，黄色镜片夜间驾驶眼镜似乎并未改善夜间行人检测，也未减少HLG对行人检测性能的负面影响。这些发现似乎不支持眼科护理专业人员建议患者使用黄色镜片夜间驾驶眼镜。
