How much do you know about 1.56 refractive index super tough photochromic lenses? Follow the editor of Best Photochromic Single Vision Grey lens to have a brief look at it!
1.56 refractive index supertough photochromic lens, which comprises: a supertough substrate, the refractive index of the supertough substrate is 1.56; a precoat, the precoat is arranged on the surface of the supertough substrate; a light photochromic layer, the photochromic layer is arranged on the upper surface of the precoat layer; hardening layer, the hardening layer is arranged on the upper surface of the photochromic layer; antireflection layer, the antireflection layer The layer is arranged on the upper surface of the hardened layer; the radiation protection layer is arranged on the upper surface of the antireflection layer; the waterproof superhard layer is arranged on the antireflection layer. On the upper surface of the radiation layer. The utility model can make the photochromic layer fade and discolor quickly, with good oxidation resistance and fatigue resistance, and no background color.
