What color sunglasses are good for your eyes?

Gray: Evenly absorbs any color spectrum, so there will be no color difference when looking at the scenery, it will only become darker, showing a real and natural feeling, and it is a neutral color.
Brown: It can filter out a large amount of blue light, which can improve visual contrast and clarity. It is good for wearing in severe air pollution (such as sandstorms) or foggy conditions.
Green: Like gray, it is a neutral color. Because it can increase the green light reaching the eyes, it is cool and comfortable, and is suitable for people whose eyes are prone to fatigue.
Blue-gray: It is a neutral color system like gray, with darker color and higher visible light absorption rate.
Mercury lenses: The lens surface is coated with high density. Can absorb and reflect more visible light, suitable for outdoor sports people.
Yellow: Strictly speaking, this type of lens does not belong to sunglasses, because it hardly reduces visible light, but can improve contrast and provide more accurate vision, so it is also called "night vision goggles". Of course, it can be used for decoration at night.
Light colors such as light blue and light pink: more decorative than practical.
