    The prevalence of color vision deficiency is about 5%. Most of them are caused by the missing or defect of one of the three cones in the retina responsible for color vision. If one cone is missing, it is called dichromacy which has three types corresponding to the three cones (protanopia, deuteranopia, tritanopia to L-, M-, S-cone respectively).   Tables 1 and 2 summarise findings from the EHB colour vision and Ishihara test. Plate 1 of both the EHB and Ishihara is a control plate with the num which can be correctly identified by both persons with normal colour vision and those with colour deficiencies.
