A commonly used method of investigating colour vision, that is, the ability of the human visual system to discriminate colours, is based on the use of isochromatic colour plates, such as those used in the Ishihara test. The present paper describes a new computer-based method of determining red/green colour vision deficiencies. The method involves the presentation of Ishihara colour plates on a computer monitor. It has been verified experimentally that, despite the differences between the spectral emission of the computer screen and the daylight reflected by the Ishihara plates, the method is capable of distinguishing between subjects with from those without colour vision deficiencies. For screening purposes, the use of a reduced number of plates is suggested. This suggestion makes use of nine instead of 14 plates, and the criterion of two incorrectly recognized plates to determine a colour vision deficiency.
一种常用的研究色觉（即人类视觉系统辨别颜色的能力）的方法是基于使用等色图版，例如石原氏色盲测验中使用的图版。本文描述了一种基于计算机的测定红/绿色觉缺陷的新方法。该方法包括在计算机显示器上呈现石原氏色觉测试图版。实验已经证实，尽管计算机屏幕的光谱发射与石原氏图版反射的日光之间存在差异，但该方法能够区分出色觉正常的人和色觉有缺陷的人。为了进行筛查，建议使用数量减少的图版。此建议采用9个而非14个图版，并以误认两个图版作为判定色觉缺陷的标准。
