进行本研究以确定显著的光波长，以提高Deutan受试者的颜色辨别能力。我们对具有Deutan和正常色觉的受试者进行了Ishihara测试和Farnsworth Panel D-15测试。利用450至660 nm的七种不同LED光和额外的D 65白色灯来改变照明条件，包括波长和强度。石原测试和D‐15测试的结果表明，无论附加D 65灯的强度如何，使用更长波长的LED都显著提高了对Deutans的颜色识别。值得注意的是，对于630和660 nm的LED波长，Ishihara测试中的Deutans的错误率<25%。在色觉正常的受试者中，D 65灯消除了石原测试中的错误，而与LED波长无关。添加D 65灯也减少了D-15测试中的交叉次数。这些结果表明，在Ishihara试验和Farnsworth Panel D-15试验中，使用波长更长（如630和660 nm）的LED光照射可使Deutans具有更强的红绿色辨别能力。© 2016 Wiley Periodicals，Inc.

This study was performed to determine significant light wavelengths to improve color discrimination ability of subjects with deutan. We conducted both the Ishihara test and the Farnsworth Panel D‐15 test for subjects with deutan and normal color vision. Seven different LED lights from 450 to 660 nm and an additional D65 white lamp were utilized to change the lighting conditions, including the wavelength and intensity. The results of the Ishihara test and D‐15 test showed that color identification of deutans was markedly improved with the longer wavelength LEDs regardless of the intensity of the additional D65 lamp. Notably, the error rates of deutans in the Ishihara test were <25% for LED wavelengths of 630 and 660 nm. In the case of subjects with normal color vision, the D65 lamp abolished the errors in the Ishihara test, regardless of the LED wavelength. Addition of the D65 lamp also decreased the number of crossings in the D‐15 test. These results suggested that illumination by LED light with longer wavelengths, such as 630 and 660 nm, may provide deutans with greater red‐green discrimination ability in both the Ishihara test and the Farnsworth Panel D‐15 test. © 2016 Wiley Periodicals, Inc.
