Charts, Eye, Color Discrimination

Definition : Eye charts designed to be used in the detection of color blindness by means of a special chart on which symbols with colored dot patterns are depicted. The devices usually consist of a plate containing several symbols made of colored dot patterns (e.g., numbers, letters, geometric shapes ) on a background of dots in randomly mixed colors (e.g., Ishihara Test plates). The patterns are visible to those with normal vision and are invisible to those with color vision deficiency (e.g., protanopia, tritanopia, deuteranopia). Color discrimination eye charts are used mainly for vision screening in healthcare facilities, at ophthalmologist offices, and in the field.
