Color weakness cannot be corrected by wearing glasses. Both color blindness and color weakness are hereditary conditions that are generally difficult to treat, and wearing glasses hardly improves color sensitivity. Since there is no effective treatment, it is unlikely to pass the driving school physical examination by wearing color weakness glasses. According to Chinese regulations, only individuals with red-green color blindness are prohibited from obtaining a driver's license. The physical examination items for obtaining a driver's license are as follows: 1. Height: Applicants for A1, A2, A3, and B2 licenses must be at least 155 cm tall, while B1 applicants must be at least 150 cm tall. 2. Vision: For regular car licenses, vision must be at least 4.9 without red-green color blindness. For large vehicles, trucks, and buses, vision must be at least 5.0. Applicants with monocular vision of 5.0 or above can apply for a regular car license. 3. Hearing: Must be able to distinguish the direction of a sound source at 50 cm with both ears. 4. Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact with normal limb and finger movement. 5. Lower limbs: Normal movement function with no more than a 5 cm difference in leg length. 6. Trunk and neck: No movement dysfunction.

As a veteran driver with decades of experience, I can confirm that color vision tests during driver's license renewal physicals can indeed be challenging for those with color deficiencies. If you have mild color blindness, wearing specialized color-correcting glasses is a viable solution. These glasses use special filters to enhance red-green differentiation, making it much easier to identify the colored dot patterns during the exam. I've discussed this with several fellow drivers who successfully passed their tests using this method, though it ultimately depends on local regulations and the doctor's discretion—some locations permit assistive devices while others insist on unaided vision. My advice is to visit an ophthalmology hospital beforehand for a professional evaluation and obtain a medical certificate as backup to avoid disputes during the exam. Safety is paramount—misinterpreting traffic signals while driving can lead to serious consequences. I once witnessed a fellow villager running a red light, which not only resulted in a ticket but also gave him a proper scare. While using such tools is reasonable, always ensure you purchase high-quality glasses from reputable sources to avoid counterfeit products that could compromise your safety.

Hey, I'm a young guy who often thinks about car safety. When it comes to the vision test for driver's license renewal, dealing with color vision issues is straightforward: wearing color-blind glasses might help you pass—they act like a little assistant to enhance color recognition. Last time I accompanied my cousin to his physical, he has mild color deficiency, wore those glasses, and passed on the first try. Of course, not all places turn a blind eye; hospitals in first-tier cities are more professional and might accept a doctor's diagnosis. Not being able to distinguish traffic lights while driving is absolutely dangerous. My friend felt much safer driving at night after using them. I recommend choosing a reputable brand like EnChroma and trying them on beforehand, while also checking the policies of the testing center—don't count on luck. Safety always comes first; don't let small issues lead to accidents.

As someone who enjoys researching automotive tools, I've looked into this topic. The driver's license renewal physical exam includes a color vision test, and color deficiency glasses are designed based on chromatic aberration compensation principles, theoretically improving visual performance. In practice, using them might help pass the test—for instance, by aiding in distinguishing subtle color contrasts in test patterns—but policies vary widely: Beijing and Shanghai have more lenient stations where doctors can make assessments, while remote areas tend to be stricter. Since misidentifying traffic signals poses significant risks while driving, using such glasses isn't a bad idea. Remember to visit designated hospitals beforehand for a check-up and obtain certification to avoid last-minute issues disrupting the renewal process. Prioritizing safety is always the most important attitude.
