How much do you know about single-sided photochromic lenses? Let's follow the quality 1.56 SF Mirror Photochromic Brown lens editor for a brief understanding!

It comprises a substrate layer, the upper surface of the substrate layer is sequentially provided with an upper hardened layer and a lower coating layer, the lower surface of the substrate layer is sequentially provided with a lower hardened layer and a lower coating layer, the substrate layer and the upper hardened layer A color-changing coating is applied between them. After the above structure is adopted, the hardened layer and coating layer arranged in sequence on the upper and lower sides of the substrate layer and the color-changing coating located between the substrate layer and the upper hardened layer are provided. In this way, not only can the light transmittance be improved by the provided coating layer and the reflection of light can be prevented, but the structure design of the one-sided color-changing coating can be placed in parallel during the coating process, which prevents the generation of air bubbles during the coating process, and also improves the In addition, the unilateral discoloration coating is located on the outside, which can also improve the sensitivity of the reaction and improve the discoloration effect.
The above is the quality 1.56 SF Mirror Photochromic Brown lens Xiaobian tells: a brief introduction to the knowledge of single-sided photochromic lenses.
