Was the Color Vision Test Cancelled for the 2020 License Renewal?
2 Answers
2020 license renewal did not cancel the color vision test. Methods of color vision testing: Generally, there are color blindness examination mirrors, color blindness examination lamps, pseudoisochromatic plates (color blindness test charts), and colored wool bundles. In recruitment and admission physical examinations, pseudoisochromatic plates and colored wool bundles are commonly used for color vision testing. The wavelength of visible light to the human eye is 390-780 nanometers, and generally, 120-180 different colors can be distinguished, including the seven main colors of purple, blue, cyan, green, yellow, orange, and red. Examination precautions: Ensure that the examiners understand the usage and significance of each chart in the color blindness test to guarantee the physical examination is conducted quickly and accurately. The test should be performed under bright diffused light or fluorescent lighting. The tested eye should be 80cm away from the chart.
As an enthusiast who follows driver's license policies, I must say that the color vision test was not abolished during the 2020 driver's license renewal. The new regulations mainly relaxed the vision requirements, such as allowing individuals with monocular vision to drive, but the color blindness test is still retained in the medical examination because recognizing traffic lights and safety signs is crucial. That adjustment was made to make things more convenient for everyone, but if the color vision test were completely canceled, it would pose road risks—just imagine color-blind friends misjudging traffic signals, which could easily lead to accidents. So, you still have to take the color vision test during renewal; don't count on luck. It's advisable to get a pre-check at the hospital in advance to ensure passing in one go. Overall, the policy optimization is more humane, but the safety bottom line remains unchanged.
