Can Color Blindness Glasses Help Pass the Driver's License Renewal Physical Examination?

[JaxonMarie]

Color blindness glasses cannot be used to pass the driving school physical examination. Below are the specific requirements for the driver's license physical examination: Height: Applicants for A1, A2, A3, B2 licenses must be at least 155 cm tall, while B1 applicants must be at least 150 cm tall. Vision: No red-green color blindness is allowed. For small vehicles, vision must be at least 4.9, while 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 small vehicle license. Hearing: Both ears must be able to distinguish the direction of a sound source within 50 cm. Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger movement functions. Lower limbs: Movement functions must be normal, and the height difference between the two legs must not exceed 5 cm. Trunk and neck: No movement dysfunction is allowed.

Last time I accompanied my neighbor to the DMV for license renewal, I specifically asked about this. The staff said the key is whether you can clearly distinguish traffic lights and the numbers/letters in the test charts while wearing glasses. They'll first use equipment to test if you have severe color blindness on site. If it's mild color vision deficiency, you can pass the color vision test by wearing professional corrective lenses. But if you completely can't distinguish red from green, no glasses will help. Remember to bring your usual color deficiency glasses on the day of the physical exam - don't borrow someone else's temporarily. Many cities now have self-service physical examination machines - make sure the device can recognize your corrective effect before entering with glasses. However, implementation may vary slightly by location, so it's recommended to consult your local DMV first.

As a technician who has designed traffic lights, I recommend that friends with color vision deficiency pay special attention to the spectral filtering effect when selecting lenses. Some cheap colorblind glasses on the market only enhance color contrast and provide limited help in recognizing the color vision test charts used for driving test physical exams. Last year, my colleague wore a popular online pair to the exam but got stuck at the number identification stage. Only after switching to custom lenses prescribed by a professional optometry institution did they pass. Those hidden animal graphics in the test charts actually contain precision tests for red-green differences, which ordinary tinted sunglasses definitely cannot handle. It's advisable to visit an ophthalmology clinic for a professional color vision assessment two weeks in advance and bring the report to the physical exam for better assurance. If you don't pass the first time on-site, don't rush to leave—communicate with the examining doctor about retesting with assistive devices.

When I was getting my driver's license, I had red-green color weakness. For the license renewal physical exam, I directly wore color weakness correction glasses bought online. The hospital had me look at three sets of test cards: one for identifying traffic sign shapes, one for recognizing number patterns, and finally a traffic light simulator. With the glasses on, I initially misidentified two in the number pattern section, but the doctor had me adjust the frame position and try again, barely passing in the end. Now, the new traffic regulations will mark 'qualified after correction' on the physical exam form. A reminder: changes in the prescription of your frame glasses can affect the color weakness correction effect, so it's best to have your color vision checked during your annual eye exam. Those with severe color weakness may be required to take an additional 'nighttime signal light recognition' test—remember to practice with a flash simulator before the exam.
