Description
Technical Field
The utility model belongs to the technical field of the lens processing, specifically speaking relates to a low refracting index's photochromic lens.
Background
Color changing lenses, also known as "photosensitive lenses". Silver halide is added into the glass lens, but at present, resin color-changing lenses are mainly used, chemical substances such as a pyriproxyfen and the like are added into the acrylic resin lenses, so that the originally transparent and colorless lenses can be changed into colored lenses to be protected when being irradiated by strong light, and the glass lenses are suitable for being used indoors and outdoors. The color-changing lens is made of optical glass containing silver halide microcrystals, and can quickly darken under the irradiation of sunlight and ultraviolet rays according to the principle of light color interconversion reversible reaction, completely absorb the ultraviolet rays and realize neutral absorption of visible light; and the color and the transparency can be quickly recovered when the lamp returns to the dark. At present, factors such as lightness, thinness, attractiveness, transmittance and color change uniformity of the color-changing lens become main concerns when consumers choose.
SUMMERY OF THE UTILITY MODEL
In view of this, the technical problem to be solved by the present application is to provide a low refractive index color-changing lens, in which a first anti-reflection film, a color-changing film, a second anti-reflection film and a third anti-reflection film are provided, and the anti-reflection film and the color-changing film cooperate to form a uniform light film layer, so that the color change of the lens is more uniform.
In order to solve the above technical problem, the present application discloses a low refractive index color changing lens, which comprises: the substrate, the refractive index of the substrate is 1.49, the substrate is made of mixed photochromic factors in resin; even light rete of setting on the substrate, even light rete is equipped with in proper order: the color-changing film is positioned between the first anti-reflection film and the second anti-reflection film, and the third anti-reflection film is bonded with the substrate; a hard coating film arranged on the light homogenizing film layer; a protective film disposed on the stiffened film.
According to an embodiment of the present invention, the first antireflection film is a silicon dioxide film.
According to an embodiment of the present invention, the second antireflection film is a titanium pentoxide film.
According to an embodiment of the present invention, the third antireflection film is a zirconia film.
According to an embodiment of the present invention, the thickness of the first antireflection film, the second antireflection film, and the third antireflection film is the same.
Compared with the prior art, the utility model discloses can obtain including following technological effect:
through setting up first anti-membrane, the membrane of discolouing, second anti-membrane and third anti-membrane of subtracting, the cooperation of anti-membrane and the membrane of discolouing forms even light rete for the more even that discolours of lens.
Of course, it is not necessary for any product to achieve all of the above-described technical effects simultaneously.

Reference numerals
The light-emitting diode comprises a substrate 10, a uniform light film layer 20, a first antireflection film 21, a color changing film 22, a second antireflection film 23, a third antireflection film 24, a hardened film 30 and a protective film 40.
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 low refractive index photochromic lens according to an embodiment of the present invention.
As shown, a low index of refraction color changing lens, comprising: a substrate 10, the refractive index of the substrate 10 is 1.49, the substrate 10 is made of a photochromic factor mixed in resin; the even light film layer 20 of setting on substrate 10, even light film 20 layer is equipped with in proper order: a first antireflection film 21, a color change film 22, a second antireflection film 23, and a third antireflection film 24, the color change film 22 being located between the first antireflection film 21 and the second antireflection film 23, the third antireflection film 24 being bonded to the substrate 10; a hard coating film 30 arranged on the light uniformizing film layer 20; a protective film 40 disposed on the stiffening film 30.
The utility model discloses an among the embodiment, substrate 10's refracting index is 1.49, and substrate 10 is made by the interior mixed light sense color-changing factor of resin, can darken rapidly when the lens under sunlight and ultraviolet irradiation, and the ultraviolet ray is absorbed completely, is the neutral absorption to visible light, gets back to the dark, can resume colorless transparent fast.
The substrate 10 is provided with the uniform light film layer 20, the uniform light film layer 20 is provided with the hard coating film 30, and the hard coating film 30 enhances the overall strength of the lens. Be equipped with protective film 40 on the hard coat 30, protect the lens surface, prevent that the lens fish tail from damaging.
Further, the light uniformizing film layer 20 is sequentially provided with: the color-changing film 22 is positioned between the first and second antireflection films 21 and 23, and the third antireflection film 24 is bonded to the substrate 10. Preferably, the first antireflection film is a silicon dioxide film, the second antireflection film is a titanium pentoxide film, and the third antireflection film is a zirconium oxide film. The thicknesses of the first antireflection film, the second antireflection film and the third antireflection film are the same. When light passes through the first antireflection film 21, part of stray light is filtered out and enters the color changing film 22, the light becomes more uniform, the color changing film 22 changes color after being irradiated by the light, the light is filtered again through the second antireflection film 23 and the third antireflection film 24, and stray light is completely filtered out. Finally, light enters the substrate, the color of the substrate changes, and the uniform light film layer 20 enables the color of the lens to be more uniform.
The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
