What are the vision requirements for the C1 driver's license physical examination?
2 Answers
For the C1 driver's license physical examination, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. The following are the vision requirements for a driver's license: 1. Regulations: For applying for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tram driving licenses, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other driving license types, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. 2. Others: For those with monocular vision impairment, if the naked or corrected vision of one eye reaches 5.0 or above on the logarithmic visual acuity chart, and the horizontal field of vision reaches 150 degrees, they can apply for a motor vehicle driver's license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or special small automatic transmission passenger cars for the disabled.
As someone who just passed the C1 driver's license test, let me share my personal experience with the vision test part. During the medical check-up, they used the standard logarithmic eye chart where you stand at a designated distance to identify E letters facing different directions. The doctor required that monocular vision (either naked eye or corrected) must reach at least 4.9 or above, which is approximately 0.8 on the decimal acuity chart - equivalent to being able to clearly see license plates at a certain distance. They also check for color vision to ensure no color blindness or weakness, otherwise you couldn't distinguish traffic lights. I wore glasses during my test and passed without issues. Poor vision can be very dangerous while driving, such as difficulty seeing pedestrians or road signs, which may lead to accidents. So I recommend avoiding excessive late-night TV watching before the license test to maintain healthy vision, and eating more carrots for eye protection in daily life.
