A compilation of diagnostic charts, often printed in a booklet format, is utilized to assess an individual’s ability to perceive color accurately. These charts, typically employing pseudo-isochromatic designs, present numbers or patterns embedded within fields of differently colored dots. The ability to discern these hidden elements indicates normal color vision, while an inability to do so may suggest a color vision deficiency.
These diagnostic tools play a crucial role in identifying individuals with congenital or acquired color vision deficiencies. Early detection enables appropriate career guidance, mitigating potential challenges in professions requiring accurate color perception. Historically, such testing materials have been instrumental in standardization of vision assessment across various industries and clinical settings.
