Abstract
The utility model discloses an anti blue light UV500 coated lens, by PMMA polymethyl methacrylate plastics optical filtering endosexine, polarisation membrane and PC polycarbonate optical filtering extexine are constituteed, the polarisation membrane inserts and puts between PMMA polymethyl methacrylate plastics optical filtering endosexine and PC polycarbonate optical filtering extexine, and it is together fixed through the bond line, the light wavelength that ends of PMMA polymethyl methacrylate plastics optical filtering endosexine and PC polycarbonate optical filtering extexine is 450~500nm. The utility model discloses simple structure can effectively see through the lens by the 450 -500nm blue light and kick into eyes, and the reduction blue light is to the injury of eyes, anti ultraviolet UV500 to the protection eyes simultaneously, can prevent dazzling glare effectively, make the more clear nature of vision.
Description
Technical field
The utility model relates to a kind of anti-blue light UV500 plated film lens.
Background technology
Eyeglass refers to one block of glass or other one or more curved surface transparent materials used, and when observing things by it, things is occurred clear, large or less.Be often used in glasses, camera, telescope etc.Glasses are the instrument of protection eyes, are again a kind of ornaments of beauty treatment, select a good glasses can play a very good protection to eyes.
At present, eyeglass generally cannot block blue light through, have blue light inject eyes through eyeglass and injure eyes in using unavoidably, accelerate the cellular oxidation in macula retinae district, excessive exposure even can damage cellula visualis.
Therefore, the present inventor studies for the structure of eyeglass specially, and develop a kind of mirrors of anti-blue light UV500 plated film, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of anti-blue light UV500 plated film lens, to reach cut-off blue light, antiultraviolet, and the effect of anti-dazzle.
In order to reach above-mentioned purpose, solution of the present utility model is:
Anti-blue light UV500 plated film lens, be made up of PMMA polymethylmethacrylate optical filtering endosexine, light polarizing film and PC polycarbonate optical filtering extexine, light polarizing film is interposed between PMMA polymethylmethacrylate optical filtering endosexine and PC polycarbonate optical filtering extexine, and be fixed together by bonding coat, the cut-off wavelength of light of PMMA polymethylmethacrylate optical filtering endosexine and PC polycarbonate optical filtering extexine is 450 ~ 500 nanometers.
The thickness on described PMMA polymethylmethacrylate optical filtering top layer is 450 ~ 500 nanometers, and the thickness that PC polycarbonate optical filtering top layer is positioned at eyeglass is 3-5 millimeter.
After adopting such scheme; the utility model structure is simple; select the lamination layer structure of PMMA polymethylmethacrylate optical filtering endosexine and PC polycarbonate optical filtering extexine specially; the two combines; effectively can end 450-500nm blue light and inject eyes through eyeglass; reduce blue light to the injury of eyes; antiultraviolet UV500; thus protection eyes; simultaneously; light polarizing film between PMMA polymethylmethacrylate optical filtering endosexine and PC polycarbonate optical filtering extexine can prevent dazzling dazzle effectively, makes vision more clear and natural.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Label declaration
PMMA polymethylmethacrylate optical filtering endosexine 1, light polarizing film 2, PC polycarbonate optical filtering extexine 3 adds dura mater 1, bonding coat 4.
Embodiment
As depicted in figs. 1 and 2, be the anti-blue light UV500 plated film lens that the utility model discloses, be made up of PMMA polymethylmethacrylate optical filtering endosexine 1, light polarizing film 2 and PC polycarbonate optical filtering extexine 3.
PMMA polymethylmethacrylate optical filtering endosexine 1 toughness is strong, larger than silex glass more than 10 times, optical good with processability, therefore design is at the inside surface of eyeglass; PC polycarbonate optical filtering extexine 3 is tough and tensile, and matter is hard, rigidity characteris, and impact resistance is good, and refractive index is high, good processability, and intensity is high, therefore design is at the outside surface of eyeglass; And PC polycarbonate optical filtering extexine 3 can also antiultraviolet UV500.The composite structure of PMMA polymethylmethacrylate optical filtering endosexine 1 and PC polycarbonate optical filtering extexine 3 can end the blue light that wavelength of light is 450 ~ 500nm, makes eyeglass have the effect of anti-blue light, plays the effect of protection eyes.The optimum thickness on PMMA polymethylmethacrylate optical filtering top layer is 3-5 millimeter, and the optimum thickness that PC polycarbonate optical filtering top layer is positioned at eyeglass is 3-5 millimeter.
Light polarizing film 2 is interposed between PMMA polymethylmethacrylate optical filtering endosexine 1 and PC polycarbonate optical filtering extexine 3, and is fixed together by bonding coat 4.Light polarizing film 2 is specifically optional is used for strange polarisation Science and Technology Co., Ltd. AP30-100 model light polarizing film.Light polarizing film 2 can intercept dazzling dazzle, makes vision more clear and natural.
In a word, the utility model utilizes Film Coating Antireflection and rete design to make high transmission rate eyeglass, this structure absorbs high-octane blue light and ultraviolet, greatly can reduce the injury to eyes, and energy electromagnetic radiation shielding, thus obtaining the filtration of best blue light and best transmittance, blue light filters 100%, transmittance 98%.
These are only preferred implementation of the present utility model; restriction not to protection domain of the present utility model; all differences do not produced with the technical solution of the utility model in essence, to the deduction or replace of above-mentioned embodiment, all should be regarded as falling within protection domain of the present utility model.
