近年来国外应用视觉对比敏感度的检测了解人的视觉功能,以协助诊断眼的疾病。传统的中心视力检查是在特定的条件下,将黑色的符号衬在白色的背景上,其对比为100%,在强光源照明下检测受检者分辨物体所甩的最小视角来确定中心视力,检查视野以了解视网膜周边部的功能。但是这种方法无法了解改变对比或视标处于动态时人们的视功能。视觉对比敏 In recent years, foreign applications of visual contrast sensitivity detection of human visual function to help diagnose eye diseases. The traditional central vision test under certain conditions, the black symbol lined on a white background, the contrast of 100%, under strong light illumination detected by subjects to distinguish the smallest object perspective to determine the center of vision, Inspect the field of vision to understand the function of the periphery of the retina. However, this method fails to understand the visual function of people when contrast is changed or the optotype is in motion. Visual contrast
