Features: Color vision is one of the visual functions of the human eye. Whether color vision is normal directly affects people's ability to learn, work, and live. Color vision testing is an important part of understanding health status and clinical work. With the continuous development of medical science, people have gained more knowledge about color vision, and some new testing methods have been designed and introduced accordingly. However, long-term practice has shown that from a practical standpoint, color vision test charts can quickly qualitatively assess color vision function within a certain range, especially suitable for the needs of large-scale physical examinations. Therefore, they are still widely used domestically and internationally. This chart can be used as a reference for eye disease prevention and treatment, health workers, and patients.
