What Color Sunglasses Are Not Suitable for Driving?
Tan sunglasses
Tan tinted sunglasses can almost isolate 100% ultraviolet rays, and the soft tone makes people feel more comfortable, making the eyes not easy to fatigue.
Grey sunglasses
Grey sunglasses can not only isolate most ultraviolet rays, but also many infrared rays, almost completely. They will not change the original color of the scenery.
However, grey sunglasses can significantly reduce the light transmittance. Generally speaking, the light transmittance is between 8% and 40%. According to the national standard, this kind of sunglasses is called sunshade, which is a kind of dark sunglasses.
Dark sunglasses will increase the driver's reaction time. Generally speaking, wearing dark sunglasses will increase the driver's reaction time by about 100 milliseconds on average.
When driving at a high speed, for example, at 120 km/h, that is 33.3 meters per second. If you increase the response time by 100 milliseconds, it is equivalent to driving 3.3 meters more before you brake because there is no response from the front.
Green sunglasses
Green is an optical three primary color, which can filter out the other two primary colors, blue and red, which will cause obvious color difference.
When driving, green sunglasses will cause the red light in the traffic lights to turn into a black light, thus affecting the driver's judgment.
