Lens color and function

The gray lens absorbs evenly on any chromatogram, so the viewing scene will only darken, but there will be no obvious color difference, showing a true natural feeling. It belongs to the neutral color system.
(2) brown lenses
Filtering out a large amount of blue light can improve visual contrast and sharpness, and it is better to wear in case of serious air pollution or fog.
(3) Green lens
While absorbing light, it maximizes the green light that reaches the eyes, so it has a cool and comfortable feeling. Suitable for people whose eyes are prone to fatigue.
(4) blue gray lens
Similar to the gray lens, it belongs to the neutral lens, but the color is deeper and the visible light absorption rate is higher.
(5) Mercury lenses
The lens surface is coated with a high density of mirrors. Such lenses are more absorbed into the visible light and are suitable for outdoor sports.
(6) yellow lens
Strictly speaking, such lenses are not part of the sunglasses because they hardly reduce visible light.
However, in foggy and dusk, the yellow lens can improve the contrast and provide more accurate video, so it is also called night vision goggles.
Some young people wear yellow lenses "sunglasses" as a decoration.
(7) Light blue, light pink and other lenses
It is also a lens that is more decorative than practical.
(8) dark green lens
It absorbs the heat and brings a cool feeling, but the light transmittance and clarity are low. It is suitable for wearing in the sun and not suitable for driving.
(9) blue lens
Beach blue beaches can be worn with sun-blue lenses, and blue can effectively filter out the light blue of sea and sky reflections.
