Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.
Referring to fig. 1, fig. 1 is a schematic view of a high refractive index photochromic lens according to an embodiment of the present invention.
As shown, a high index of refraction color shifting lens, comprising: the refractive index of the substrate 10 is 1.71, the number of the substrates 10 is set to 2 groups, a refraction enhancement layer 11 is bonded between the 2 groups of the substrates 10, and the refraction enhancement layer 11 is made of optical glass; a color-changing agent film layer 20 coated on the substrate 10; a hard coating layer 30 disposed on the color-changing agent film layer 20; an antireflection film layer 40 disposed on the hard coat layer 30, where the antireflection film layer 40 includes an upper first antireflection film 41 and a lower second antireflection film 42, the first antireflection film 41 is made of silicon dioxide, and the second antireflection film 42 is made of zirconium oxide; and a protective film layer 50 disposed on antireflective film layer 40.
In an embodiment of the present invention, the number of the substrates 10 is set to 2 groups, the refraction enhancement layer 11 is adhered between the 2 groups of substrates 10, and the material of the refraction enhancement layer 11 is optical glass.
