Types and characteristics of sunglasses lenses

1. Gray lens: The gray lens can absorb any color spectrum evenly, so the scene will only become darker, but there will be no obvious chromatic aberration, showing a real and natural feeling. It belongs to the neutral color system.

2. Brown lenses: filter out a large amount of blue light, which can improve visual contrast and clarity. It is better to wear under severe air pollution or foggy conditions. Generally, it can block the reflected light from a smooth and shiny surface, and the wearer can still see the subtle parts. It is an ideal choice for drivers.

3. Green lens: while absorbing light, it maximizes the green light reaching the eyes, so it has a cool and comfortable feeling, suitable for people who are prone to eye fatigue.

4. Blue-gray lenses: similar to gray lenses, they belong to neutral lenses, but the color is darker and the visible light absorption rate is higher.

5. Mercury lens: The lens surface adopts high-density mirror coating. Such lenses absorb more reflected visible light and are suitable for outdoor sports people.

6. Yellow lens: Strictly speaking, this type of lens is not a sunglass lens, because it hardly reduces visible light, but in foggy and twilight hours, yellow lens can improve the contrast and provide more accurate vision, so it is also called night vision mirror. Some young people wear "sunglasses" with yellow lenses as decoration.

7. Light blue, light pink and other lenses: the same lenses are more decorative than practical.

8. Dark green lens: It absorbs heat and brings a cool feeling, but the light transmittance and clarity are low. It is suitable for wearing in the sun, but not when driving.

9. Blue lenses: Sun blue lenses can be worn when playing on the beach. Blue can effectively filter out the light blue reflected by the sea and sky. We should avoid using blue lenses when driving, because it will make us unable to distinguish the color of the traffic signal.
