摘要
A colour-blindness device and a colour-blindness testing method. The colour-blindness device includes: an input device and an output device (3; 13), a power supply adapter, an industrial mainboard (1), a VGA board (2), a memory (5) and a power supply module (4). The testing method includes a first stage and a second stage: in the first stage, randomly displaying colour-blindness test pictures, and judging whether the person being tested falls into the category of normal, colour weakness or total colour blindness and total colour weakness according to the statistics on whether the person being tested has correctly recognized the colour-blindness test pictures; if yes, then saving and/or outputting the judgment resu if no, performing the second stage; and in the second stage, randomly displaying the colour-blindness test pictures, judging the colour-blindness type according to the circumstances regarding identification of the colour-blindness test pictures by the person being tested, and saving and/or outputting the judgment result. Using the colour-blindness device to perform colour-blindness tests can give an accurate and error-free judgment on the colour vision health condition of the person being tested, improving the accuracy and scientificity of the tests, improving working efficiency, and eliminating the effect of irregular testing methods and standards.
