  • Abstract
  • Look Inside

Two new types of color vision tests were designed to assess faulty color recognition in color vision deficiencies based on principles as are different from conventional color vision tests. In one, the subject is asked to choose either of red, green and gray lines among 10 lines that are randomly colored in red, green, gray, yellow or blue. In the other, the subject is asked to select a total of 10 red azalea blossoms dispersed among numerous green leaves. Seventy-five congenital color-deficient persons and 20 normal subjects were examined. As a result, the number of correct answers differed significantly between dichromats and anomalous trichromats, and between anomalous trichromats and normal subjects. These tests are easy, sensitive and reproducible. They reflect the faulty color recognition that occurs unconsciously in color-deficient persons in their daily lives and may be useful in judging the qualifications required in their occupations.
