What Is The Principle Of Color-Changing Cycling Glasses?
What is the principle of color-changing cycling glasses
Color changing glasses can change the color of the lens according to the intensity of the external light, so as to protect the eyes from the stimulation of strong light. Therefore, many friends will choose to wear color changing glasses when riding. However, many friends do not know the principle of color changing biking glasses, but the working principle of color changing glasses is actually very simple:
1. During the production of color-changing cycling glasses, light and color materials are added to the glass raw materials. The lenses contain silver halide (silver chloride, silver bromide) microcrystals.The colorless silver halide breaks down into opaque silver atoms and transparent halogen atoms. The silver atoms absorb light, reducing the transmittance of the lens and changing the color of the glasses.
2. As the halogen in the color-changing lens will not be lost, it can have a reversible reaction. After the activation light disappears, the silver and halogen will be recombined to make the lens return to the original transparent colorless or light-colored state.
Ride often outdoors, need to withstand the stimulation of the sun, so it is better to wear a pair of cycling glasses that can change color, but some friends worry that the change of color cycling glasses will be harmful to the eyes, so will the change of color cycling glasses harm the eyes?
Riding color changing glasses harmful to the eyes
The light transmittance of color-changing cycling glasses is relatively low. Although they can absorb most ultraviolet, infrared and various harmful glare, the light transmittance of the lenses is relatively poor due to the chemical composition of silver halide contained in the lenses. Long-term use of the lenses may lead to visual fatigue, so it is not suitable for long-term cycling wear.However, with the progress of manufacturing technology, the discoloration rate and fading rate of the discoloration lens have been greatly improved. High-quality discoloration cycling glasses are almost harmless.
Also note that there are some inferior color uneven discoloration cycling glasses, slow or discoloration, fading fast, or discoloration, slow fading fast, some even don't change color, this kind of glasses Dai Jiu to ride is unable to make effective eye protection, should pay attention to when buying buy two lenses is the same quality, no difference of color cycling glasses.
