Scope

Scope: This document specifies the requirements, test methods, working principles, inspection rules, marking, packaging, transportation, and storage of color deficiency (blindness) detectors. This document is applicable to devices used to test the color recognition ability of subjects. Main technical content: Based on the internationally recognized Ishihara test (main methods include the JND test, the color axis test, and the Ishihara test), the initial status of the subject's color discrimination ability is confirmed. Then, by using color comparison, the subject's perception of different colors is further distinguished to identify the type of color discrimination deficiency they have. Finally, digital technology is used to conduct detailed classification and analysis of the subject's vision, ultimately enabling precise differentiation of their color perception. Through background data analysis, relatively accurate color vision differences are obtained. Based on these differences, optical compensation methods can be used to compensate for missing color bands, allowing colorblind/color-deficient individuals to see the same colors as normal people and experience the colorful world. Digital, standardized, and intelligent devices replace traditional identification methods, ensuring high efficiency, accuracy, and objectivity, and reducing susceptibility to human or external influences.
