What is the best color for drivers to wear sunglasses?

Let's talk about the lenses of sunglasses first. Sunglasses are divided into four types according to the depth * * *, which are 15%, 34%, 50%, 70% and 15% in turn. They are the shallowest, suitable for indoor and outdoor wear, especially for people with eyes and degrees, which can avoid the trouble of taking them off and putting them on. 34% depth, suitable for general use in the sun. 50% sunglasses can be worn in the hot sun and by the sea. Sunglasses are 70% for special purposes and are generally used in engineering majors such as electric welding. The depth of lens color only affects the absorption of visible light, and has nothing to do with the anti-ultraviolet ability. The anti-ultraviolet ability is only related to the lens material. Then introduce the color of the lens, gray: it absorbs evenly for any color spectrum, so the scenery will not appear color difference, but will only darken, showing a true and natural feeling, belonging to a neutral color system. Brown: it can filter out a lot of blue light, improve visual contrast and clarity, and wear well when air pollution is serious (such as sandstorm) or foggy. Green: Like gray, it belongs to neutral color system, because it can increase the green light reaching the eyes, so it is cool and comfortable, suitable for people with tired eyes. Blue-gray: Like gray, it belongs to neutral color system, with dark color and high absorption rate of visible light. Mercury lens: High-density coating on the lens surface. It can absorb and reflect more visible light and is suitable for outdoor sports people. Yellow: Strictly speaking, this kind of lens is not sunglasses, because it can hardly reduce visible light, but can improve contrast and provide more accurate visual images, so it is also called "night vision goggles", and of course it can also be used for decoration. Light colors such as light blue and light pink: decorative is more than practical. If it is practical to buy sunglasses, it is recommended to wear a polarizer from Baosheng or Weston. If you want to consider the decorative effect of sunglasses, you'd better choose brightly colored lenses. Love today reported 2007-11-1221:40.
