Purpose

The purpose of this study was to compare sign identification distances and driving performance metrics in presbyopic participants while wearing multifocal contact lenses (MFCL) and while wearing progressive addition lens (PAL) spectacles.

Methods

19 presbyopic participants completed PAL spectacle assessments and contact lens fitting and follow up visits before driving assessments began. These assessments occurred in a simulator equipped with a full-sized sedan on a motion platform and a 260 degree screen. Participants completed the driving task with PAL and with MFCL. Participants followed a lead car and identified signs at various distances from the road. For the two wearing conditions, comparisons of the distance along the road at which signs were identified were made using repeated measures ANOVA. Paired t-tests were used to compare driving performance for the two conditions.

Results

There was no statistical difference in sign identification distance between PAL and MFLC for signs 32.0 m from the road side of the road (182 ± 46 m for MFCL; 205 ± 45 m for PAL; P = 0.07) or 51.4 m from the side of the road (204 ± 43 m for MFCL; 216 ± 36 m for PAL; P = 0.3). Only signs 70.2 m from the roadside showed a significant difference (207 ± 42 m with MFCL; 232 ± 39 m with PAL; P = 0.01), All distances were greater than those required to safely stop a vehicle. There were no significant differences in the driving performance metrics between the refractive corrections.

Conclusion

Driving performance metrics were similar for MFCL and PAL spectacles. Sign identification distances with both eyewear types were well within the distances required for safe vehicle stopping.

驾驶模拟器中多焦点隐形眼镜佩戴者的驾驶表现和道路标志识别

目的

本研究的目的是比较老花眼参与者在佩戴多焦点隐形眼镜 (MFCL) 和佩戴渐进多焦点镜片 (PAL) 眼镜时的标志识别距离和驾驶表现指标。

方法

19 名老花眼参与者在驾驶评估开始前完成了 PAL 眼镜评估和隐形眼镜验配以及随访。这些评估是在配备有运动平台上的全尺寸轿车和 260 度屏幕的模拟器中进行的。参与者用 PAL 和 MFCL 完成了驾驶任务。参与者跟随一辆领先的汽车并识别距道路不同距离的标志。对于两种佩戴条件,使用重复测量方差分析对识别标志的沿道路距离进行比较。配对 t 检验用于比较两种条件下的驾驶性能。

结果

对于距路边 32.0 m 的标志(MFCL 为 182 ± 46 m;PAL 为 205 ± 45 m;P = 0.07)或距路边 51.4 m,PAL 和 MFLC 之间的标志识别距离没有统计学差异。道路(MFCL 为 204 ± 43 m;PAL 为 216 ± 36 m;P = 0.3)。只有距路边 70.2 m 的标志显示出显着差异(MFCL 为 207 ± 42 m;PAL 为 232 ± 39 m;P = 0.01),所有距离均大于安全停车所需的距离。屈光矫正之间的驾驶性能指标没有显着差异。

结论

MFCL 和 PAL 眼镜的驾驶性能指标相似。两种眼镜类型的标志识别距离都在安全车辆停车所需的距离之内。
