Color Vision Tests

Color Vision Tests . Confusion lines form the basis of many color vision tests such Pseudoisochromatic plates. Pseudoisochromatic plate tests are also commonly used in the clinic to screen for color vision deficiency. Colors are carefully chosen based on the confusion lines.

Color vision

Different cone photo-receptors have opsin molecules which are differentially sensitive to certain wavelengths of light – these are the physical basis of color. The cones are classified as S, M or L, depending on their color sensitivity. Color vision. Fig 15-23.

Color Vision Deficiency

Color blindness occurs whenever you are not able to find colors in the usual way. It is also known as color vision deficiency. Color blindness is a condition when someone cannot distinguish between certain colors. It typically occurs between greens and reds, and sometimes blues.
