Contrast sensitivity is a key visual ability for everyday tasks, as well as a potential indicator of important optical and neurological diseases. Current clinical standards, based on visual discrimination performance on printed charts, present problems that could be bypassed using electronic devices. This work describes the development of new tests for contrast sensitivity, based on the detection of a moving target on a computer screen and in virtual reality headset. It presents preliminary evaluation of these innovations by comparison of their performance, using healthy adults with normal vision and by artificially altering their contrast sensitivity. The results demonstrate consistent correlation between all test modalities explored.
对比敏感度是日常任务中的一项关键视觉能力，也是重要的眼部和神经疾病的潜在指标。基于印刷图表上视觉辨别性能的当前临床标准存在一些问题，而使用电子设备可以绕过这些问题。这项工作描述了基于在计算机屏幕和虚拟现实头戴式设备上检测移动目标的对比敏感度新测试的开发。通过将其性能与视力正常的健康成年人进行比较，并人为改变他们的对比敏感度，对这些创新进行了初步评估。结果表明，所探索的所有测试模式之间存在一致的相关性。
