1. Sunny days: in the morning, the air clouds are thin, the ultraviolet ray is less blocking, and it reaches the ground more, so the depth of the color-changing lens in the morning is also deep. In the evening, the ultraviolet light is weak, because the sun is far away from the ground in the evening, during the day due to the accumulation of fog after blocking most of the ultraviolet light; So the depth of discoloration is very shallow at this point.

2, overcast: ultraviolet light is sometimes not weak, but also can reach the ground, so the lens can still change color. It is almost transparent indoors, and the color-changing lens can provide the most suitable ultraviolet and glare protection for glasses in any environment. The color of the lens can be adjusted timely according to the light, which can not only protect the vision, but also provide health protection for eyes anytime and anywhere.

3. The relationship between the color change sheet and the temperature: under the same conditions, with the increase of the temperature, the color of the color change lens will gradually become lighter with the increase of the temperature; On the contrary, as the temperature decreases, the chameleon will slowly get deeper. Therefore why the summer discoloration is shallow, winter discoloration is deep this reason.

4. Color change speed, depth and lens thickness also have a certain relationship
