It depends on the specific vision condition. Here are the relevant regulations regarding vision requirements for obtaining a driver's license: Vision in both eyes: 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 in both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other driving license types, the naked or corrected vision in both eyes must reach 4.9 or above on the logarithmic visual acuity chart. Single eye vision: For those with single eye vision impairment, if the better eye's naked or corrected vision reaches 5.0 or above on the logarithmic visual acuity chart and the horizontal visual field reaches 150 degrees, they can apply for a motor vehicle driving license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or small automatic transmission passenger cars specially designed for disabled people.

My neighbor experienced this situation. His right eye is almost blind, but his left eye has exceptionally good vision. When consulting the driving school, he learned that as long as the naked or corrected vision of the good eye reaches above 5.0 and the horizontal field of vision exceeds 150 degrees, one can apply for a C1 or C2 driver's license. He specifically underwent a professional visual field test, and the results showed that his left eye fully met the standards. However, it's important to note that licenses for large trucks or buses have strict requirements for both eyes. Now, he has been driving for five years and says he mainly relies on frequently checking the rearview mirrors to compensate for blind spots, and he habitually adjusts several times when parking. Daily commuting is not a problem, but he is extra cautious during rainy or foggy weather.

I heard the doctor discussing this when accompanying my cousin for his physical exam the other day. The current is quite humane - people with monocular vision impairment can obtain a driver's license as long as they meet several key conditions: First, the good eye must meet the vision standard (wearing glasses to achieve clear vision is acceptable); Second, the horizontal visual field range must be sufficiently wide (cooperate carefully during testing); Finally, they can only apply for small vehicle licenses. It's recommended to first get a formal visual field test at a top-tier hospital (this requires a separate test order). My cousin has amblyopia in one eye but 1.2 vision in the other, and the doctor said his 160-degree horizontal visual field fully qualifies. He's currently practicing for the second driving test subject.

I obtained my driver's license with monocular vision impairment, and the most memorable part was the medical examination for the driving test. The doctor would cover the good eye and ask me to read the eye chart, then test the vision level of the impaired eye alone. Finally, I had to focus on a light point in the device to measure the visual field angle, turning my eyes like playing a game. Actually, the hardest part wasn't getting the license but the initial adaptation period, such as always having to turn my head to check the blind spot twice when changing lanes. Now, I've installed a curved rearview mirror in my car and always turn on the fog lights in rainy weather. I recommend beginners practice reversing in enclosed areas first to develop a sense of distance. Remember to have regular vision check-ups, especially if your myopia worsens, and change glasses promptly.

According to the latest "Regulations on the Application for Motor Vehicle Driver's Licenses," whether individuals with monocular vision can obtain a driver's license depends on three strict criteria: the dominant eye must have uncorrected or corrected visual acuity of at least 5.0, a horizontal visual field greater than 150 degrees, and no other eye conditions that could impair driving. It's important to note that visual field testing is often overlooked, and inaccuracies can occur due to instrument errors or insufficient head rotation. It is recommended to undergo a re-examination at a qualified medical center. Once approved, applicants can apply for a Class C driver's license. However, professional drivers, such as those operating taxis or freight vehicles, must meet binocular vision standards. For safety reasons, it is advised not to drive on highways during the first six months after obtaining the license.

As someone who has gone through the entire process, let me share the key points. First, you must confirm whether the affected eye is completely blind—like in my case, my left eye can still sense light, so it doesn't count as total blindness. During the medical exam, bring all your medical records, as the doctor will focus on testing your color discrimination and dynamic vision. The reverse parking part of the driving test was particularly challenging for me, requiring about two weeks more practice than usual. After getting my license, I found night driving to be the most demanding, especially when oncoming headlights cause temporary glare. Now, I've developed four habits: always turning on daytime running lights, adjusting the rearview mirror slightly outward, maintaining a 20% greater following distance on highways, and getting an annual eye exam. After all, safety is the top priority.
