Abstract
The invention discloses an eyeglass lens of a layered structure. The middle layer of the layered structure is made of glass, the upper surface and the lower surface of the middle layer are provided with an upper surface layer and a lower surface layer respectively, the upper surface layer and the lower surface layer are made of resin, the thickness of the upper surface layer and the thickness of the lower surface layer are the same, and the thickness of the upper surface layer and the lower surface layer is smaller than that of the middle layer. According to the eyeglass lens, by means of the multi-layer composite structure, the middle layer of the composite structure is made of the glass, and the two ends of the middle layer are made of the resin, so that on one hand, the weight of the eyeglass lens is lightened, and on the other hand, the eyeglass lens is high in hardness and good in abrasion resistance.
Description
Technical field
The present invention relates to a kind of Anti-myopic eye eyeglass.
Background technology
The kind of eyeglass is very many, and material is also very various, and we select different eyeglass at the function different according to glasses.The work that the color of eyeglass is high and stable to the vision requirement of eyesight, color and distance, as the student, the automobilist, the surgeon, art workers etc. should select water white eyeglass.(2) it is relatively good that the transmittance of eyeglass has the ultra-thin optical lens transmittance of the optical mirror slip of multi-layer anti-reflective film, colourless optical mirror slip and aspheric surface.(3) thickness of eyeglass and eyeglass diopter size, refractive index, picture frame size shape, interpupillary distance size and to move photocentre amount, axis of astigmatism, eyeglass character (concavo-convex) etc. relevant should be selected according to prescription after the medical science optometry.(4) weight of eyeglass is relevant with lens materials, and glass mirror is than resin lens weight.Identical lens materials, the heavy weight less than proportion, the weight that bulky specific volume is little (relevant with the profile size with the eyeglass number of degrees).(5) the hardness glass mirror of eyeglass is higher than resin lens hardness, more wear-resisting.(6) the intensity resin eyeglass of eyeglass is higher than glass mirror intensity, shock-resistant non-friable.Current lens can not have hardness height and lightweight advantage simultaneously.
Because the defect that above-mentioned existing lens exists, the design people, actively research and innovation in addition, to founding a kind of lens of new structure, make it have more practicality.
Summary of the invention
Fundamental purpose of the present invention is, overcomes the defect that existing lens exists, and a kind of lens of new structure is provided, and has higher intensity, and weight is lighter, thereby more is suitable for practicality, and has the value on industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of lens proposed according to the present invention, described lens is layer structure, and the middle layer of layered structure is glass material, and the upper surface in described middle layer and lower surface arrange respectively upper epidermis and lower top layer.
Aforesaid lens, described upper epidermis and lower top layer are resin material.
Aforesaid lens, described upper epidermis is identical with the thickness on lower top layer.
Aforesaid lens, the thickness on described upper epidermis and lower top layer is less than the thickness in described middle layer.
By technique scheme, lens of the present invention at least has following advantages:
Lens of the present invention, by adopting multi-layer compound structure, the middle layer of composite structure adopts glass material, and both sides adopt respectively resin material, have alleviated on the one hand the weight of lens, have on the other hand higher hardness and wearing quality.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.
The accompanying drawing explanation
The structural representation of Fig. 1 lens of the present invention.
Embodiment
Reach for further setting forth the present invention technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment of the present invention is described in detail as follows.
Lens of the present invention as shown in Figure 1, lens is layer structure, the middle layer 1 of layer structure is glass material, the upper surface in middle layer 1 and lower surface arrange respectively upper epidermis 2 and lower top layer 3, upper epidermis 2 and lower top layer 3 are resin material, upper epidermis 2 is identical with the thickness on lower top layer 3, and the thickness on upper epidermis 2 and lower top layer 3 is less than the thickness in middle layer 1.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (4)
1. a lens, it is characterized in that: described lens is layer structure, and the middle layer of layered structure is glass material, and the upper surface in described middle layer and lower surface arrange respectively upper epidermis and lower top layer.
