u003cbru003eThe sun is dazzling in summer, and many people like to wear sunglasses when driving. Which kind of sunglasses is better to wear when driving? How to choose? Polarized sunglasses are like installing blinds in front of your eyes. When driving, sunlight is projected on the road or on the hood, and the light is polarized to produce glare. Glare is irregular reflection of light, which will increase the brightness and at the same time reduce the color saturation, directly irritating the eyes, making the eyes feel tired and unable to look at objects for a long time. 'If the eyes are too dazzling when driving, it will definitely be dangerous.' The polarizer can effectively arrange and filter out these irregular reflected light, just like putting blinds in front of our eyes, and the light is adjusted to the same direction of light entering the eyes. Can make the scene look soft and not dazzling. Sunglasses with brown lenses are suitable for foggy weather. In severe air pollution or foggy weather, you can wear brown sunglasses. The brown lens reduces the brightness of the object, and at the same time, the color distortion of the object is small, and the halo of blue light can be slightly reduced, so that the image is clearer, and at the same time, it provides glare protection. Wang Ying reminded drivers that they should avoid using blue lenses when choosing glasses, because it will make the driver confused about the color of traffic lights; do not wear too dark lenses when driving, which will cause 'chromatic aberration'. , The red light and the green light can be seen clearly, which is more dangerous. For sunglasses with high transmittance lenses, the low transmittance affects the response ability. Driving fast and wearing sunglasses with too low transmittance will affect the driver’s responsiveness. In order to ensure that the colors of the surrounding environment are not distorted, the edges of objects are clear, and the ability to recognize different color signal lights, the relevant stipulation transmittance is: observe the red, yellow, and green traffic signals through the lens, the red signal should be ≥8%; yellow And the green signal should be ≥6%; if the transmittance of each color traffic signal is too low, it will reduce the ability to identify the traffic signal. Therefore, when buying sunglasses, consult the transmittance. Reflective sunglasses, look at the dashboard more clearly. The lens of reflective sunglasses is coated with a thin layer of gradient reflective paint, and the color depth of the paint gradually changes from top to bottom. When driving, it can enhance the resistance of sunglasses to light from above, while allowing more light to enter from below and horizontally. Reflective sunglasses can block the sun's rays from above, while also allowing the driver to see the dashboard more clearly. clip, suitable for those who wear frame glasses. The sunglasses clip can be turned up and down. When driving, as long as the sunglasses clip is turned down to cover the myopia lens, it will block the glare and protect the eyes. Wang Ying said that the sunglasses clip is suitable for myopia patients who wear frame glasses. When the light is dark, just flip up or take off the sunglasses clip, it is a pair of myopia glasses; of course, if you don’t like the clip, you can also buy it directly.
