An evaluation of computer based color vision deficiency test: Egypt as a study case

Color vision deficiency (CVD) refers to the inability to distinguish different dominant colors. CVD is an inherited defect that causes a damage or functionality weakness in one or more of color receptors in human eyes. There are a lot of well-known traditional clinical tests for CVD diagnosis. One of these tests is the Ishihara plates. In this paper, an evaluation study of using computerized diagnosis system compared to the traditional plates. In this study, 267 volunteers have been checked using both traditional ishihara plates and a computer system and LCD monitors. The study shows an identical diagnosis results which indicates that the new technologies can replace the traditional clinical tests or can be used for screening purpose in hard testing conditions.
