Contrast sensitivity has been identified as a significant index of visual function, and as an indicator of visual disorders. The Arden test of contrast sensitivity has been recognized as a simple and easily administered technique for measurement of this process. However, the customary method of administration of this test involves manual manipulation and considerable individual subjectivity. The instrument described in this report was designed and developed to minimize variability in the testing procedure due to differences in individual testing techniques, and to standardize testing conditions, ambient illumination, viewing distance and rates of presentation.
对比敏感度已被确认为视觉功能的一项重要指标，也是视觉障碍的一个指标。对比敏感度的 Arden 测试已被公认为一种用于测量此过程的简单且易于实施的技术。然而，该测试的常规实施方法涉及人工操作且存在相当大的个体主观性。本报告中描述的仪器旨在设计和开发，以尽量减少由于个体测试技术差异导致的测试过程中的变异性，并使测试条件、环境照明、观察距离和呈现速率标准化。
