Do You Really Know the Red Lines of Traffic Laws? Key Points of Regulations in Different Regions
To help you understand better, here are the key points of common regulations in the EU and California.
(1) EU EN 1836 Standard
In the EU, sunglasses are regulated according to the EN 1836 standard. One crucial indicator is that the light transmittance of the lenses must be greater than 8%. This number is not randomly set; there are profound safety considerations behind it. When driving during the day under strong sunlight, lenses with low light transmittance can effectively block UV rays and intense light, making your vision more comfortable.
However, in low - light environments like cloudy days, at dusk, or when entering a tunnel, if the lens light transmittance is less than 8%, it will dim your vision. You may have difficulty distinguishing road signs and vehicle outlines, greatly increasing the risk of traffic accidents such as rear - end collisions.
(2) California Vehicle Code §27400
Now, let's turn our attention to California, USA. The California Vehicle Code §27400 strictly restricts lens colors. Red and blue lenses are explicitly prohibited while driving in California. This is because these colored lenses can seriously interfere with the correct identification of traffic light colors. Imagine wearing prescription sunglasses with red lenses at an intersection.
You might mistake a red light for another color and run the red light, causing a serious traffic accident and endangering your life and the lives of others. If you violate this regulation and are caught by the traffic police, you may face a fine or even have points deducted from your driver's license, bringing a lot of inconvenience to your travel and life.
Test Data Reveals Lens Differences
(1) Experimental Background and Purpose
To understand more intuitively the impact of different - colored lenses on driving safety, researchers conducted a rigorous experiment. After all, in daily driving, light conditions are complex and changeable, from bright noon sunlight to dim twilight.
The right lens color can significantly affect our judgment of road conditions. This experiment focused on the twilight environment, a period with weak and rapidly changing light, which poses a considerable challenge to drivers' visual abilities. The researchers hoped to find out which lens color could better ensure driving safety by comparing the performance of different - colored lenses in this environment.
(2) Experimental Process
The experiment was carried out in a professional driving test site that simulated the twilight environment. The light in the site simulated the brightness and color temperature of real - life twilight to restore the actual driving scenario as much as possible. The participating drivers all had rich driving experience and normal vision or corrected - to - normal vision.
They wore brown - colored lenses and gray lenses respectively and drove at a specified speed on the simulated road. During the driving process, the brake lights would randomly turn on ahead. The drivers needed to react immediately and press the corresponding button. The device would accurately record the time from when the brake lights turned on until the driver reacted, to measure the impact of different lenses on the speed of identifying brake lights.
(3) Experimental Results
According to the research data in the "Journal of Safety Research", after multiple repeated experiments, the average speed of drivers wearing brown - colored lenses to identify brake lights was 0.3 seconds faster than that of drivers wearing gray lenses. Don't underestimate this short 0.3 - second difference. At high - speed driving, it could be the critical time to avoid a rear - end collision. Further analysis found that brown - colored lenses can better filter out blue light and enhance light contrast, making the red signal of the brake lights more prominent and easier for drivers to catch. Although gray lenses can reduce glare, they are less effective than brown - colored lenses in enhancing contrast, resulting in a slightly slower reaction speed for drivers.
Driving Glass Sets Loved by Veteran Drivers
(1) The Secret of Polarized Lenses
Among many types of lenses, polarized lenses are like "eye - protecting magic weapons" for driving. Their working principle is like installing a precise light filter for your eyes. The light we encounter daily, especially when driving, reflects off various surfaces such as roads, water, and the windshields of the cars in front.
These reflected lights often form chaotic glare, like dazzling beams, directly interfering with our vision. The internal molecular structure of polarized lenses is like a fine - meshed venetian blind, which can precisely filter out these horizontally reflected lights and only allow light in a specific direction to pass through. It's like opening up a clear visual channel in the ocean of strong light, making the roads, vehicles, and pedestrians we see clearer and sharper.
(2) The Ingenious Design of the Clip - on Visor
When driving in and out of tunnels, the sudden change in light is always a headache. This is where the clip - on visor comes in handy. Its design is very clever, with a clip - on structure that can be easily fixed on glasses, which is convenient and quick. When you're about to enter a tunnel while driving, just flip down the visor. It can effectively reduce the intensity of the light entering your eyes, allowing your eyes to adapt smoothly to the dim light in the tunnel and avoiding temporary blindness or blurred vision caused by the sudden change in light.
When you drive out of the tunnel and the sunlight becomes strong again, the visor can continue to work, blocking the dazzling sunlight and enabling you to quickly regain a clear vision, ensuring driving safety. This feature of being able to adjust flexibly according to light changes greatly improves the convenience and safety of driving, allowing you to handle complex - light road conditions with ease.
