Contrast sensitivity, a more recent test of visual function, has never been studied in its relationship to sports vision. The hypothesis that contrast sensitivity functions among college varsity level baseball players significantly differs from that of a random sample of optometry students was tested using Arden grating plates. A statistically significant difference was found at the 98 percent confidence level, demonstrating that in this study, a sample of college varsity level baseball players have higher level contrast sensitivity functions than those of a randomly selected sample of Southern California College of Optometry students.
对比敏感度是视觉功能的一项较新测试，其与运动视觉的关系从未被研究过。使用阿登光栅板对大学一级棒球运动员的对比敏感度功能与验光专业学生随机样本的对比敏感度功能存在显著差异这一假设进行了测试。在98%的置信水平上发现了统计学上的显著差异，表明在本研究中，大学一级棒球运动员样本的对比敏感度功能水平高于南加州验光学院随机抽取的学生样本。
