Description
Technical field
The present invention relates to a kind of plastics polaroid glasses.
Background technology
Spreadlight lens is applied widely in daily life, such as watch polarised light formed pattern, for stop reflected light through, for secret display, for liquid crystal panel electric performance test etc.
As polarized lenses, usually there are two kinds of modes, a kind of is formed in the mode of plastic lens substrate surface laminating light polarizing film, and a kind of is the structure forming light polarizing film in plastic lens substrate inside.
For rear a kind of polarized lenses, in the fabrication process, when eyeglass inside, front and back buries light polarizing film underground; usually a packing ring can be used; ring packing ring is formed with the supporting protuberance for supporting light polarizing film, is formed with insertion groove, in this insertion groove, inserts light polarizing film at the end face of supporting protuberance.Considerably increase the thickness of polarized lenses and the possibility of light polarizing film location dislocation like this.On the other hand, when a large amount of polaroid adopts this sandwiched type structure in prior art, also there is light polarizing film and hold flaky problem.
Summary of the invention
Given this, the invention provides and a kind ofly take into account permanent applicability plastics polaroid glasses practical again.
In order to realize goal of the invention of the present invention, the invention provides a kind of plastics polaroid glasses, comprise temple, picture frame and eyeglass, described eyeglass is polarized lenses, and it comprises:
Front lens layer, it has the face of object side;
Rear lens layer, it has the face of eyeball side; And
Polarisation rete, it is arranged between described front lens layer and described rear lens layer, and and distance between the face of the object side of described front lens layer be less than 1.1mm, this distance minimum value is 0.25mm;
Wherein, described light polarizing film is formed by thermoplastic polyester, and described polarisation rete and between front lens layer and rear lens layer, there is adhesive coatings, described adhesive coatings is made up of urethane resin, and described urethane resin is polymerized by the structural unit of polytetramethylene glycol or polybutadiene and the structural unit of isocyanic acid and is formed.
According to above-mentioned plastics polaroid glasses, it is characterized in that, the refractive index of described front lens layer and described rear lens layer is 1.59.
According to the present invention, due to the object side of described front lens layer face between distance be less than 1.1mm, this distance minimum value is 0.25mm, therefore, it is possible to produce the plastics polaroid glasses identical with common lens thickness.
According to the present invention, described light polarizing film towards described front lens layer object side face convexly, can fit between front lens layer and rear lens layer along the surface extending of front lens layer object side like this.
According to the present invention, the refractive index of described front lens layer and described rear lens layer is 1.59.Also can be that only described rear lens layer has diopter.
According to the present invention, described light polarizing film is formed by thermoplastic polyester, and described polarisation rete and between front lens layer and rear lens layer, there is adhesive coatings, described adhesive coatings is made up of urethane resin, and described urethane resin is polymerized by the structural unit of polytetramethylene glycol or polybutadiene and the structural unit of isocyanic acid and is formed.
