Contrast sensitivity (CS) has recently emerged as an important predictor of visual performance. Few studies, however, have been published involving CS and its role in vision for sport. The purpose of this investigation was to determine if significant differences occurred in CS between female professional and collegiate tennis players who wore daily-wear soft contact lenses (N = 10) and those players who wore no corrective lenses (N = 10) in competition as measured by the Stereo Optical Optec 2000 Vision Tester. Subjects were between the ages of 18 and 37 years. Mean ages were 21.76 (+/- 4.018) and 25.40 (+/- 5.379) years for those wearing lenses and those not, respectively. Each subject was preliminarily screened for SVA-distance, lateral/vertical phorias, stereopsis, and color perception. All subjects were within accepted limits. CS was assessed at 1.5, 3, 6, 12, and 18 cycles per degree (cpd). Each subject was assessed monocularly; eye initially assessed was determined randomly. A 2 x 2 factorial analysis of variance (alpha = .05) was used to analyze data. No significant differences were found between eyes. Significant differences were found at 3, 6, 12, and 18 cpd. It may be concluded that those female professional and collegiate tennis players wearing no corrective lenses were significantly higher in CS at intermittent and high spatial frequencies than those who wore daily-wear soft contact lenses in competition.
对比敏感度（CS）最近已成为视觉表现的重要预测指标。然而，很少有关于CS及其在运动视觉中作用的研究发表。本研究的目的是确定，通过立体视觉光学Optec 2000视觉测试仪测量，在比赛中佩戴日抛型软性隐形眼镜的女性职业网球运动员（N = 10）和不佩戴矫正眼镜的运动员（N = 10）之间的CS是否存在显著差异。受试者年龄在18至37岁之间。佩戴镜片者和未佩戴镜片者的平均年龄分别为21.76（±4.018）岁和25.40（±5.379）岁。对每位受试者进行了远视力、水平/垂直隐斜视、立体视觉和色觉的初步筛查。所有受试者均在可接受范围内。在每度1.5、3、6、12和18周/度（cpd）的条件下评估CS。对每位受试者进行单眼评估；最初评估的眼睛随机确定。采用2×2析因方差分析（α = 0.05）分析数据。两眼之间未发现显著差异。在3、6、12和18 cpd时发现了显著差异。可以得出结论，在比赛中，那些不佩戴矫正眼镜的女性职业和大学网球运动员在间歇性和高空间频率下的CS显著高于佩戴日抛型软性隐形眼镜的运动员。
