What are the tricks for the color blindness test during driver's license physical examination?

In essence, there are no tricks for the color blindness test during the driver's license physical examination. Color blindness means the inability to distinguish certain types of colors. For individuals with color blindness, the type of color they cannot recognize determines their specific color blindness. If they cannot recognize any colors, it is termed total color blindness. To pass the driving test physical examination, a more straightforward approach for those with color blindness is to wear color blindness correction glasses or undergo treatment, as the inability to distinguish colors cannot be bypassed with minor tricks. More details are as follows: 1. Color blindness correction glasses: Similar to myopia, color blindness can be corrected with specialized glasses. The principle of these correction glasses is based on complementary color antagonism, where a special coating on the lens blocks certain wavelengths. Long wavelengths of natural light can pass through, while short wavelengths are reflected. These color blindness correction glasses come in two types: contact lenses and frame glasses. Of course, if the goal is to pass the physical examination, contact lenses might be more suitable. 2. Color blindness does not completely disqualify one from obtaining a driver's license: The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" only specifies that "red-green color blindness" disqualifies one from applying for a motor vehicle driver's license. For other types of color blindness or color weakness, as long as the test is passed, one can still apply as usual.
When it comes to the color blindness test charts in the driver's license physical exam, I used a little trick last year when I took the test: those charts mainly check if you can distinguish between red and green, since driving requires recognizing traffic lights. The trick is to practice at home first by downloading a color blindness test app to familiarize yourself with the common patterns of numbers or animal shapes hidden in circles. Make sure the lighting is adequate and avoid strong light shining directly into your eyes, as it might affect your judgment. If you can’t see something clearly, don’t rush to guess—take a few deep breaths to calm down and try again more carefully. If it still doesn’t work, be honest with the doctor; they can switch the testing method or recommend an eye exam. Remember, the test isn’t about passing—it’s about ensuring you can drive safely.
