Do you know any common questions about color-changing lenses? The editor of Best Photochromic Single Vision Grey lens will take you to find out.
1. The lens can change color, will the light transmittance affect it?
After the lens is discolored, it can be used as sunglasses. At this time, the function is to block the sunlight. At this time, the light transmittance will naturally decrease. If the light transmittance of the original transparent state is maintained, the function of the sunglasses will be lost. After the color is restored, its light transmittance will return to its original state, which has no effect on vision.
2. What is the reason why the color changer does not change color?
The color change of the color film is related to two factors, one is the light condition, and the other is the color change factor. If it does not change color under light conditions, then its color change factor has been destroyed, so that the lens cannot change color.

3.What are the special optical characteristics of color-changing lenses?
Some chemicals are added to the color-changing lens, so that the originally transparent and colorless lens will turn into a colored lens when exposed to strong light for protection. It will change the depth of the color with the change of the light intensity. The stronger the light, the deeper the color change; it is comfortable to wear, not fatigue after long-term use, and has good chemical stability and mechanical strength. It can be used as daylight anti-glare goggles for fieldwork, plateau and snow workers.
