摘要
人类视功能:形觉、光觉、对比敏感度、暗适应、色觉的光敏阈值和色调分辨力随年龄增加而有改变。颜色视觉比光觉和形觉要求更高的分辨力,研究正常老年人的色觉改变,是评价老年性眼病色觉损害的前提。
In this study,75 normals(100 eyes)with presenium and geratic period was measured byFarnsworth-Munsell 100-Hue Test(FM 100-hue test).The results showed the mean errorscore square of each spectral region and whole spectral was increased as age becomes older,the loss of hue discrmination correlated with age.The authors discussed the reason of huediscrmination was decreased in senility.
