Abstract
The utility model relates to a glasses lens material. The optical center of the glasses lens material is deviated from the geometric center horizontally, and the thickness is transited from the periphery towards an optical center point gradually. The peripheral degree of the glasses lens material is transited from the interior towards the exterior. The glasses lens which has the advantages of uniform thickness, beautiful appearance, light weight and more comfortable wearing can be cut out.
Description
Technical field
The utility model relates to a kind of Sheet material for eyeglass.
Background technology
At present, need the personage who wears glasses more and more in daily life, yet all there are following problem in existing myopia, spectacles for long sight eyeglass: the eyeglass near nasal side is thin and thick near the eyeglass of ear side, and such eyeglass not only outward appearance is ugly but also heavy.Cause the main cause of this phenomenon to be that at present used Sheet material for eyeglass structure is reasonable inadequately.Please refer to Fig. 1 is the synoptic diagram of commonly using Sheet material for eyeglass, and existing Sheet material for eyeglass 1 ' optical centre a ' and geometric center b ' are on same straight line.Commonly use the use of Sheet material for eyeglass, because people face width difference, and the specification of spectacle frame is basic identical, so when wearing glasses, people's pupil focus often can not overlap with the geometric center of eyeglass.And in order to make clear picture, the pupil focus must overlap with the optical centre a ' of eyeglass, and so, for the optical centre a ' that makes pupil focus and glasses overlaps, when cutting out eyeglass as required, the optical centre of Sheet material for eyeglass need be offset about 5mm usually.Weak point is so to cause eyeglass near nasal side thin and near the thick phenomenon of eyeglass of ear side, not only influences attractive in appearancely, wears also comfortable inadequately.
The utility model content
The purpose of this utility model just is: a kind of Sheet material for eyeglass is provided, can determine thickness evenly, appearance looks elegant, component is slim and graceful, wear more comfortable eyeglass.
For solving the problems of the technologies described above, technical scheme provided by the utility model is:
A kind of Sheet material for eyeglass, the optical centre offset geometric center of described Sheet material for eyeglass, to optic center point transition gradually, the number of degrees of the periphery of Sheet material for eyeglass are transition gradually from inside to outside from periphery for its thickness.
The distance of optic center point offset geometric center is 2-6mm.
According to the technical scheme that the utility model provides, it has following advantage with respect to prior art:
Because the optical centre offset geometric center of Sheet material for eyeglass, the number of degrees of the periphery of Sheet material for eyeglass are transition gradually from inside to outside, can make the lens thickness determined evenly, appearance looks elegant, component is slim and graceful, it is more comfortable to wear.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is a diagrammatic cross-section of commonly using Sheet material for eyeglass;
Fig. 2 is a former material diagrammatic cross-section of the present utility model;
Fig. 3 is an abrasion site diagrammatic cross-section of the present utility model;
Fig. 4 is a product profile of the present utility model.
The figure number explanation
1 ' Sheet material for eyeglass a ' optical centre b ' geometric center
1 former material 11 eyeglass material a optical centres
The b geometric center
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 4, be product profile of the present utility model, the optical centre a of Sheet material for eyeglass 11 departs from horizontal geometric center b.To optical centre a attenuation gradually, the number of degrees of the periphery of Sheet material for eyeglass 11 reduce the thickness of Sheet material for eyeglass 11 from inside to outside gradually from periphery.
The former material 1 of Sheet material for eyeglass as shown in Figure 2, is the concavees lens shape of the thick intermediate thin of periphery, when utilizing mold injection molding, with the optical centre a offset horizontal geometric center b of former material, the distance of optical centre a offset geometric center can be 2mm in the present embodiment between 2-6mm.The thinnest point of optical centre a place concavees lens.Sheet material for eyeglass adopts former material 1 is obtained through the processing of several times abrasive method, with the periphery of former material successively by the grinding order of the number of degrees from small to large attrition process successively, as shown in Figure 3, then can obtain the Sheet material for eyeglass 11 that reduces gradually from inside to outside to the number of degrees of the periphery of optical centre a attenuation gradually, Sheet material for eyeglass 11 from periphery.
When Sheet material for eyeglass of the present utility model is the thin convex lens of thick middle periphery, also optic center point can be departed from the center of circle, convex lens from periphery to optical centre thickening gradually.
Adopt the Sheet material for eyeglass of said structure can use the person of the wearing glasses visual field more clear open, because the eyeglass thickness is even, the appearance looks elegant component is also slimmer and more graceful simultaneously, thus make wear more comfortable.
Claims (2)
1, a kind of Sheet material for eyeglass is characterized in that: the optical centre offset geometric center of described Sheet material for eyeglass, to optic center point transition gradually, the number of degrees of the periphery of Sheet material for eyeglass are transition gradually from inside to outside from periphery for its thickness.
2, the described Sheet material for eyeglass of claim 1 is characterized in that: the distance of described optic center point offset geometric center is 2-6mm.
