Types and colors of sunglasses lenses

Sunglasses are available in brown, gray, green and light blue, etc. The characteristics and colors of sunglasses lenses are related.

First, the depth of the lens color

The depth of the lens color only affects the visible light absorption performance, and has nothing to do with the anti-ultraviolet ability. Because ultraviolet rays are invisible light, the ability to resist ultraviolet rays depends on the material of the lens, not the shade of color. Some resin flakes are colorless and transparent, but still 100% UV resistant. Some sunglasses are progressive color resin lenses, that is, the top is dark and the bottom is light, and it is directly close to colorless. This kind of sunglasses can block the sunlight from the top and front when worn outdoors.

Second, the color and characteristics

1. Light blue lenses Light blue and light pink lenses are also more decorative than practical.

2. Blue-gray lenses Blue-gray lenses are similar to gray lenses, both of which are neutral lenses, but have a darker color and a higher absorption rate of visible light.

3. Yellow lenses Strictly speaking, yellow lenses do not belong to sun lenses, because such lenses hardly reduce visible light, but in foggy or dusk, yellow lenses can improve contrast and provide more accurate video, so it is also called night vision mirror. Some young people wear "sunglasses" with yellow lenses as a decoration.

4. The green lens maximizes the green light reaching the eyes while absorbing light, so it feels cool and comfortable, suitable for people who are prone to eye fatigue.

5. Gray lenses can absorb any color spectrum evenly, so the viewing scene will only become darker, but there will be no obvious chromatic aberration, showing a real and natural feeling. It is a neutral color. It has a very good absorption effect on harmful rays and is 100% UV-resistant.

6. Brown lenses Brown lenses filter out a lot of blue light, which can improve visual contrast and clarity, and the wearing effect is better in severe air pollution or foggy conditions.

7. Mercury lens The surface of the mercury lens adopts high-density mirror coating. Such lenses absorb and reflect more visible light and are suitable for outdoor sports people.
