How much do you know about fast-changing photochromic lenses? Customized 1.56 SP SF Photochromic lens with blue cut Xiaobian brings you a brief understanding.

The fast-change photochromic lens includes a lens base layer, a photochromic layer, a barrier layer and a protective layer that are stacked in sequence; the barrier layer is an aqueous thermal curing coating. Further, the fast-change photochromic lens also includes a The hardened layer on the protective layer; the hardened layer can further improve the hardness of the surface of the fast-change photochromic lens. The fast-change photochromic lens of the utility model is provided with a barrier layer between the photochromic layer and the protective layer to protect the The barrier layer cannot directly contact the photochromic layer, and the barrier layer is a water-based thermal curing coating, the barrier layer will not corrode and damage the photochromic layer, so that the life of the fast-changing photochromic lens is greatly improved, and the problem of fast-changing photochromic lenses is solved. The problem of short lifespan of color-changing lenses. At the same time, because the protective layer cannot directly contact the photochromic layer, the color-changing depth of the lens will not be significantly weakened, which can effectively improve the color-changing depth.
The above is customized 1.56 SP SF Photochromic lens with blue cut Xiaobian tells: a brief introduction to the knowledge of fast-changing photochromic lenses.
