It is an object of the invention to provide a kind of ultra-thin glasses and its picture frame preparation method, especially for near-sighted glasses and the eye of farsighted glasses
Mirror wearer, designs 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 of design, with convenient
Eyeglass wearer is selected, when polishing raw material eyeglass, directly determines at the center of eyeglass in picture frame geometric center.In reality
In the production process of border, for same money picture frame, only picture frame geometric center to nasal side need to be offset to common eyeball center（That is eyeglass
Center）, and the ratio of picture frame is accordingly reduced, the structure of other picture frames do not change, in other words, as by picture frame ratio
Example reduces and shortens picture frame geometric center distance.The picture frame so designed is reduced for the requirement of raw material optic diameter, you can
To produce the raw material eyeglass that diameter dimension is smaller, and the smaller raw material eyeglass of diameter dimension can just reduce thickness naturally
Degree, as ultra-thin glasses.
A kind of ultra-thin eye glass frame preparation method by shortening distance between picture frame geometric center, by picture frame geometric center
The distance between foreshorten to people eyes interpupillary distance distribution in the range of, and picture frame maximum gauge be less than 50mm.
Beneficial effects of the present invention：
1. the present invention makes eyeglass more frivolous when being made to eyeglass, more attractive in appearance, the raw material of eyeglass can not only be saved, is made
Machining eyeglass process more facilitates, the effective processing efficiency for improving eyeglass.
The present invention is completely superposed when center of lens with mirror holder center, and optic diameter is reduced made eyeglass out than passing
The eyeglass of system is more frivolous,
3. 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 and
Oneself is with oneself interpupillary distance identical glasses.
The picture frame of the present invention has specification not of the same race, and the mirror holder of different size can install the mirror of same specification
Piece,
5. the present invention be applied to different age group crowd, especially children during wearing spectacles because eyeglass is blocked up, it is attractive in appearance
Property it is not enough, children is unwilling wearing spectacles, the number of degrees of Kids eyeglasses can for a long time deepened, the eyesight later to children is treated
Bring bigger difficulty.
The ultra-thin glasses of the present invention have reformed the mode that user selects glasses, and manufacturer just produces multiple with a spectacle-frame
The spectacle-frame of interpupillary distance size, user selects and oneself eyes interpupillary distance identical spectacle-frame.Advantage of this is that the maximum of picture frame
Diameter can at utmost reduce, so as to reduce the requirement to raw material optic diameter, raw material optic diameter may diminish to 35mm-
50mm, lens thickness is significantly reduced, and the weight of glasses mitigates significantly, while expanding raw material eyeglass utilization scope, is made
Be considered as that the minor diameter raw material eyeglass of waste product in production process also has and can apply part originally.
