Detection method for color discrimination ability

Abstract

The invention relates to a detection method for color discrimination ability. The detection method comprises the following steps of: step 1, preliminary judgment of color weakness: preliminarily judging the color vision condition of a testee; step 2, subdivision of red and green color weakness: accurately measuring the red and green color vision ability defects of the testee; step 3, detailed analysis of color vision perception: obtaining color discrimination ability values of the testee at different angles; step 4, confirmation of color vision defect degree: detecting the color discrimination ability defect degree of the testee; step 5, spectrum-based color perception: performing spectrum-based treatment on detection data and / or results to draw a corresponding curve graph. The detection method can accurately and efficiently detect the color discrimination ability defect degree of a patient, so that the color vision of the patient can be corrected in the later period.

Description

technical field [0001] The invention relates to a method for detecting color blindness and / or color weakness, in particular to a method for detecting color discrimination ability. Background technique [0002] According to published literature and statistics, according to different races, the proportion of the global population with color blindness / color weakness is between 4% and 8%. Most of the color blindness comes from genetics, so the probability of color blindness in men is much higher than that in women, and red and green color blindness is the majority. About 7~10% of the male population in the world has abnormal color vision, and the proportion of color weakness in white people is higher than that in yellow people. high. In China from 1932 to 1957, according to published professional papers and authoritative statistics (color blindness statistics 3), males were about 5.14% and females were about 0.73%. However, with the popularization of electronic products and cha...

Problems solved by technology

[0004] At present, the commonly used inspection methods for color vision disorders are: color mixing tester method, FM-100 hue detection method, D-15 hue detection method, color blindness mirror, Holmgren (Holmgren) color thread group method, colored pencil recording method , color light test, etc., as well as color visual evoked potential inspection for abnormal color vision; but the existing detection methods for color vision impairment have defects such as single effect and difficult to judge; "Color Blindness Check Chart" was first drawn by Stilling (iStilling, 1810-1879), and later remade by Shinobu Ishihara; the color blindness check chart of Rabkin (Kpac-Haren -Pa6KvH) that was used in 1936 is also of the same nature; the above-mentioned color vision There are many problems in the clinical examination chart: ①Different light and angles will lead to deviations in the results; ②It is mainly judged by human perception, which is prone to errors; Can identify color blindness / color weakness, but cannot provide precise data
