1. What is the principle of color change Cycling glasses

Trimous glasses can change the color of the lens according to the strength of the external light, thereby protecting the eyes from strong light stimulation. Therefore, many friends choose to wear colorful glasses when riding, but many friends do not know the principle of color change Cycling glasses.The working principle is simple:

1. When making color -changing Cycling glasses, the light color material is added to the glass raw material. The lens contains silver (silver chloride, silver bromide) microcrystalline.Electronics, the electrons are captured by silver ions and reacts: colorless silver is decomposed into opaque silver atoms and transparent halogen atoms. The silver atom absorb light to reduce the light transmission rate of the lens, so the color of the glasses changes.

2. Because the halogen in the color changing lens is not lost, the reversible reaction can occur. After the activation of the light disappears, the silver and the halogen are reused to restore the lens to the original transparent colorless or light -colored state.

riding is often outdoors and needs to be stimulated by the sun. Therefore, it is better to wear a pair of discolored Cycling glasses. However, some friends are worried that the color changing Cycling glasses will be harmful to the eyes.Intersection

2. Is riding colorful glasses harmful to the eyes?

The light transmission rate of color -changing Cycling glasses is relatively low. Although it can absorb most of the ultraviolet, infrared rays, and various harmful glare, due to the halogen chemical components contained in the lens, the light transmission rate of the lens is relatively poor. If it is used for a long time, it is used for a long time.It may cause visual fatigue and not suitable for long -term cycling.However, with the advancement of manufacturing technology, the discoloration rate and fading rate of color -changing lenses have greatly improved, and high -quality color -changing Cycling glasses almost have no harm.

In addition, it should be noted that there are some inferior color -changing Cycling glasses unevenly discolored, either slow color change, fast fading, or fast discoloration and slow fading, and some even do not change color at all. This Riding glasses can not be worn for a long time.For effective eye protection, you should pay attention to buying two lenses when you buy.
