Features: This book is drawn according to the theory of color vision and the theory of chromaticity complementary color, based on the principle of pseudo-isochromatic plates. It has been tested using an automatic color difference meter, ensuring accurate color usage and complete compliance with requirements. The book contains a total of 66 test plates, including 38 numerical plates, 13 Latin letter plates, and 15 animal plates. The plates can comprehensively assess red-green-yellow-blue (purple) color vision and classify red-green-blue (purple) color weakness into heavy, moderate, and light degrees, achieving both qualitative and semi-quantitative standards for color vision tests. With a large number of plates, each plate focuses on a single concept, making it easy to master reading speed and reducing the risk of misdiagnosis or missed detection. It is a comprehensive, user-friendly, and well-classified tool for color vision testing. This book is widely applicable in hospitals, epidemic prevention, military, schools, and research institutions.
