In order to examine the influence of contact lenses and visual acuity on recordings of saccadic eye movements with the infrared reflection method, horizontal 20 and 30 degrees saccades were recorded with and without contact lenses in 16 subjects (32 eyes) usually wearing contact lenses. As far as the main parameters of the saccades (accuracy, peak velocity and duration) were concerned, the reliability of the measurements (recognizable through the mean values) was not essentially influenced by the contact lenses. The precision of the measurements (recognizable through the standard deviation) was with the contact lenses significantly but, for clinical use, not essentially worse. The velocity waveforms of the saccades, however, were considerably changed by contact lenses in some cases. This is why examinations, in which saccadic velocity waveforms are used for diagnosis, should be performed without contact lenses. Visual acuity had no measurable influence on the main parameters of the saccades. However, considerably more corrective saccades were observed with contact lenses than without. There were reasons to believe that not the contact lenses themselves, but better visual acuity was responsible for the larger number of corrective saccades.
为了研究隐形眼镜和视力对红外反射法记录眼跳运动的影响，对16名通常佩戴隐形眼镜的受试者（32只眼）在佩戴和不佩戴隐形眼镜的情况下记录了水平20度和30度的眼跳。就眼跳的主要参数（准确性、峰值速度和持续时间）而言，测量的可靠性（通过平均值可识别）基本上不受隐形眼镜的影响。测量的精度（通过标准差可识别）在佩戴隐形眼镜时显著降低，但对于临床应用来说，本质上并没有更差。然而，在某些情况下，隐形眼镜会使眼跳的速度波形发生相当大的变化。这就是为什么在使用眼跳速度波形进行诊断的检查中，应该在不佩戴隐形眼镜的情况下进行。视力对眼跳的主要参数没有可测量的影响。然而，观察到佩戴隐形眼镜时的矫正性眼跳比不佩戴时多得多。有理由相信，不是隐形眼镜本身，而是更好的视力导致了更多的矫正性眼跳。
