The weight of glasses can be made to become big, aesthetic property reduction, and cause to produce uncomfortable, near-sighted eyeglass during eyeglass wearer wearing spectacles
It is due to that center of lens distance and human eye interpupillary distance difference are larger, and causes temporo side mirror piece partially thick, although and common ultra-thin glasses can be
Made moderate progress on weight and aesthetic property, but effect is not notable, and also it is expensive, the both sides eyeglass number of degrees of special glasses are not
Meanwhile the thickness and weight of eyeglass are also different, the situation of the swelling and hanging down of either of the testes can be produced during long-time is worn, shadow is caused to eyesight
Ring.The centre distance of traditional mirror holder is generally in more than 70mm, but the interpupillary distance overwhelming majority of human eye so exists not over 70mm
In eyeglass manufacturing process, eyeglass and mirror holder will produce certain deviation in installation process, cause eyeglass blocked up.
After elected horizontal glass frame and eyeglass, after the interpupillary distance of wearing glasses is obtained, by the raw material of long sight or myopia or astigmatism
Eyeglass is first placed on vertometer（Measure the eyeglass number of degrees and determine the instrument of center of lens point and the axle degree of astigmatism）On, in long sight
Or central point is marked on the lens surface of myopia or astigmatism, the astigmatism axle degree of eyeglass wearer is inputted when having astigmatism such as eyeglass,
Then mirror holder or blade are placed on wafer lapping machine and are scanned, the size of data of framework or blade is scanned onto wafer lapping machine,
The interpupillary distance of eyeglass wearer is inputted first, and eyeglass is arranged on diaphragm machine according to the data of input and the shape of eyeglass is entered
Row polishing, makes the shape of eyeglass be polished into that with mirror holder or blade structure is completely the same, then installs the eyeglass after polishing
On mirror holder.In this process, it is desirable to the eyeball center of the necessary face eyeglass wearer in the center of eyeglass, and in polishing eyeglass
When the diameter of eyeglass that also requires to be polished have to be larger than distance b of the center of lens apart from picture frame distalmost end.
The content of the invention
The purpose of this utility model is to provide a kind of ultra-thin glasses, especially for near-sighted glasses and the eyeglasses-wearing of farsighted glasses
Person, design the glasses of a kind of geometric center of eye glass frame and the center superposition of eyeglass.
Above-mentioned purpose is realized by following technical scheme：
For the eyeglass wearer of different interpupillary distances, the different same money picture frame of one group of picture frame geometrical center to center specification is designed, with
Convenient glasses wearer selects, and when polishing raw material eyeglass, directly determines at the center of eyeglass in picture frame geometric center.
In actual production process, for same money picture frame, only picture frame geometric center need to be offset to common eyeball center to nasal side（I.e.
Center of lens）, and the ratio of picture frame is accordingly reduced, the structure of other picture frames do not change, in other words, as by mirror
Frame scale smaller simultaneously shortens picture frame geometric center distance.Requirement of the picture frame so designed for raw material optic diameter reduces,
The smaller raw material eyeglass of diameter dimension can be produced, and the smaller raw material eyeglass can of diameter dimension drops naturally
Low thickness, turn into ultra-thin glasses.
The beneficial effects of the utility model：
The utility model makes eyeglass more frivolous when being made to eyeglass, more attractive in appearance, can not only save the original of eyeglass
Material, make machining eyeglass process more convenient, the effective processing efficiency for improving eyeglass.
The utility model is completely superposed when center of lens with mirror holder center, and optic diameter is reduced made eyeglass out
It is more frivolous than traditional eyeglass.
Because traditional picture frame centre-to-centre spacing is excessive, patient is merely able to the mirror holder for selecting oneself to like wherein, it is difficult to choose
With oneself and oneself interpupillary distance identical glasses.Picture frame of the present utility model has a specification not of the same race, and the mirror holder of different size
The eyeglass of same specification can be installed.
The utility model be applied to different age group crowd, especially children during wearing spectacles due to eyeglass mistake
Thickness, aesthetic property deficiency, makes children be unwilling wearing spectacles, the number of degrees of Kids eyeglasses can for a long time deepened, later to children
Eyesight treatment brings bigger difficulty.
Ultra-thin glasses of the present utility model have reformed the mode that user selects glasses, and manufacturer just produces with a spectacle-frame
The spectacle-frame of multiple interpupillary distance sizes, user select and oneself eyes interpupillary distance identical spectacle-frame.Advantage of this is that picture frame
Maximum gauge can at utmost reduce, and so as to reduce the requirement to raw material optic diameter, raw material optic diameter may diminish to
35mm-50mm, lens thickness are significantly reduced, and the weight of glasses mitigates significantly, while are expanded raw material eyeglass and utilized model
Enclose so that be considered as that the minor diameter raw material eyeglass of waste product in production process also has and can apply part originally.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the relative position schematic diagram of traditional center of lens and picture frame center.
Embodiment：
Embodiment 1：
A kind of ultra-thin glasses, its composition include：Picture frame 1 and and the eyeglass in picture frame, described picture frame it is several
What center 2 overlaps with the center 3 of described eyeglass, or the distance between picture frame geometric center is than the distance between center of lens
Greatly, but it is above the length of distance between center of lens and is not more than 3mm.The maximum gauge of described eyeglass is less than 50mm, picture frame
The distance between geometric center is identical with interpupillary distance.
The definition of the geometric center of picture frame is identical by the distance in geometric center to two solstics of picture frame, therefore theoretical
On, when center of lens is in picture frame geometric center, the minimum picture frame geometric center of diameter of raw material eyeglass is farthest to two, picture frame
The distance of point.As shown in Fig. 2 a is distance of the picture frame center to picture frame solstics in figure, b is center of lens to picture frame solstics
Distance, it is clear that as long as center of lens and picture frame geometric center are misaligned, b is naturally larger than a.As shown in figure 1, when center of lens with
When picture frame geometric center overlaps, b is equal to a, and at this moment b is exactly that the diameter of raw material eyeglass is minimum.
