Abstract
The invention relates to the technical field of manufacturing and processing of glasses and in particular relates to a thinned long-sight glasses lens and a preparation method of the thinned long-sight glasses lens. Compared with the prior art, the thickness and weight of the novel processed long-sight glasses lens are reduced by 30%-40% in comparison with the conventional long-sight glasses lens; the limit of a glasses frame is removed under the condition that the original sight correcting function is ensured; the glasses lens is suitable for any type of glasses frame; the glasses lens has the novel advantages of being light and thin, so that the wearers feel comfortable, and thus the requirements of the consumers are met.
Description
Technical field
The present invention relates to glasses and manufacture processing technique field, is a kind of thinning hyperopic lens and preparation method thereof concretely.
Background technology
Hyperopic lens, because the characteristic of " thick, heavy ", is not only worn uncomfortable but also brings very large inconvenience to the people suffering from comparatively serious long sight.Hyperopic lens can be divided into two large classes by processing type: namely a class relies on die casting to become various luminosity for existing sheet, another kind of for garage sheet be cut into various luminosity with blank.Xian Pian manufacturer is applicable to various mirror holder in order to its product, therefore all does larger by the diameter of eyeglass and thickness, to guarantee to cut dress processing.Garage sheet then according to mirror holder size, can adjust optic diameter, thus reaches its thinning object.Limitation due to this reduction processing is limited by mirror holder size, so its shortcoming is also obviously, namely on the mirror holder of large-size, cannot embody its thinning effect completely.
The present invention is in machining eyeglass design, breach the simple theory of traditional spherical lens or non-spherical lens, based on the processing characteristics of Freeform turning machine, design and invented new thinning hyperopic lens and preparation method thereof, make eyeglass can embody both light and thin feature completely on the mirror holder of any size, wearer is made to feel comfortable, to satisfy the demands of consumers.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, devise a kind of eyeglass that makes and can embody both light and thin feature completely on the mirror holder of any size, wearer is made to feel comfortable, with thinning hyperopic lens satisfied the demands of consumers and preparation method thereof.
In order to achieve the above object, the present invention devises a kind of thinning hyperopic lens, comprise hyperopic lens, optical visible district, gradual change thinning area and cut edge processing district, it is characterized in that: the middle section of hyperopic lens is optical visible district, the fringe region of hyperopic lens is cut edge processing district, region between optical visible district and cut edge processing district is gradual change thinning area, optical visible district and gradual change thinning area adopt progressive method transition, gradual change thinning area and cut edge processing district also adopt progressive method transition, and cut edge processing district is connected with mirror holder.
A preparation method for thinning hyperopic lens, is characterized in that: the thinning hyperopic lens of described one, is prepared in accordance with the following steps:
Step 1, chooses hyperopic lens, divides optics visible area, gradual change thinning area and cut edge processing district;
Step 2, uses Freeform turning machine to carry out progressive thinning turning for gradual change thinning area;
Step 3, revises hyperopic lens;
Step 4, according to the intrinsic shape of picture frame mirror holder, carries out cut edge processing to cut edge processing district;
Described optical visible district is set as Φ 30mm-55mm scope according to mirror holder and interpupillary distance.
Described cut edge processing district is hyperopic lens edge 5mm scope.
In described hyperopic lens correction, the curved extent of amendment of arc is 0 °-30 °.
In described hyperopic lens correction, top rake extent of amendment is 0 °-15 °.
In described hyperopic lens correction, nearly eye distance scope is 5mm-20mm.
The power range of described hyperopic lens is 0.00-+10.00D.
The present invention compared with the existing technology, make the novel hyperopic lens after processing comparatively in traditional hyperopic lens, thickness and weight thinning 30%-40%, when ensureing that original function of correcting defects of vision is constant, eliminate the restriction of picture frame mirror holder, keep both light and thin new advantage while making eyeglass can be applicable to any a picture frame mirror holder, make wearer feel comfortable, to satisfy the demands of consumers.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of thinning hyperopic lens of the present invention.
Fig. 2 is preparation method's schematic flow sheet of a kind of thinning hyperopic lens of the present invention.
See Fig. 1,1 is hyperopic lens, and 2 is optical visible district, and 3 is gradual change thinning area, and 4 is cut edge processing district.
Embodiment
The invention will be further described by reference to the accompanying drawings.
See Fig. 1 and Fig. 2, the present invention devises a kind of thinning hyperopic lens, comprise hyperopic lens 1, optical visible district 2, gradual change thinning area 3 and cut edge processing district 4, it is characterized in that: the middle section of hyperopic lens 1 is optical visible district 2, the fringe region of hyperopic lens 1 is cut edge processing district 4, region between optical visible district 2 and cut edge processing district 4 is gradual change thinning area 3, optical visible district 2 and gradual change thinning area 3 adopt progressive method transition, gradual change thinning area 3 and cut edge processing district 4 also adopt progressive method transition, and cut edge processing district 4 is connected with mirror holder.
The present invention devises a kind of preparation method of thinning hyperopic lens, it is characterized in that: the thinning hyperopic lens of described one, is prepared in accordance with the following steps:
Step 1, choose hyperopic lens, divide optics visible area 2, gradual change thinning area 3 and cut edge processing district 4, such design breaches the simple theory of traditional spherical lens or non-spherical lens, completely solve the problem that traditional reduction is limited by lens dimension, eyeglass is alleviated completely thinning, and can be arranged in picture frame completely;
Step 2, Freeform turning machine is used to carry out progressive thinning turning, according to the size of mirror holder frame, on the basis meeting optical visible district 2 scope for gradual change thinning area 3, accomplished ultimate attainment thinning for eyeglass, then filled the area of absence in mirror holder by gradual change thinning area 3;
Step 3, revises hyperopic lens, wears custom for wearer, arranges that suitable arc is curved, top rake and nearly eye distance, and wearer is felt comfortably cool custom;
Step 4, according to the intrinsic shape of picture frame mirror holder, carries out cut edge processing to cut edge processing district 4;
In the present invention, optical visible district 2 is set as Φ 30mm-55mm scope according to mirror holder and interpupillary distance.
In the present invention, cut edge processing district 4 is hyperopic lens edge 5mm scope.
