Description
Technical field
The utility model is related to a kind of glasses, more particularly to a kind of near-sighted prevention and control function mirror.
Background technology
The height of China's adolescent myopia incidence oneself be common to all.Its reason is prolonged near-distance reading and book
Write, human eye is necessarily adjusted in close eye, gather, the athleticism of miosis three sees object.Regulation makes eyes
Crystalline lens protuberance, set makes the intraocular flesh of eyes shrink, and it is near-sighted that prolonged close eye produces eye fatigue.Near
The degree that distance is adjusted and gathered with the moment reducing reaches pre- myopic-preventing occurrence and development with this, and this theory obtains eye regarding light
Know together on boundary.
As rate of myopia is soaring, eye regards light circle expert according to eye imaging principle, " the regulation theory " of comprehensive causes of myopia
" modern age repays theory " combines using the inside prism combination in the additional bottom of additional lower degree convex lenses and with common correcting spectacle lens.Market
The brand mainly having：" A.B mirrors ", " Reduction of Students' Study Load mirror ", " recurrence mirror ", " easy Solecare ", " China of state glasses ", " Mai Kangmaidige Rhizoma Sparganiis
Mirror ", numerous brand combined eyeglasses and the ophthalmic len such as " neutron mirror ".
These brand products mainly use Second Mate's glasses or three-purpose mirror combination technique, such as：“A.B mirrors " are Second Mate's glasses, A mirrors
For：Normal glasses of correcting defects of vision, B mirrors are：Use the inside prism in the additional bottom of lower degree convex lenses to wear for closely reading and writing to use
Mirror, it is very inconvenient to be used alternatingly；As there is three-purpose mirror such as in market development：" easy Solecare " brand product uses interior epi mirror Third Mate
Mirror, first pair of glasses are scope, and glasses of correcting defects of vision are worn by A nearsighted person, and second pair of glasses is that diopter is left+3.00
Right convex lens, Third Mate's glasses are the inside prism of substrate.Its occupation mode is basic using glasses for myoporthosis is worn
On according to epi mirror purposes, using different composite mode：Together with the modes such as magnetic, fastener, intermediate plate, screw are combined with scope.
Understand, market sold two with the saturating combined eyeglasses of rib using relatively easy, usually normally use correction of myopia,
Depending on it is near when wear rib lens combination, be also simple possible reluctantly；And three-purpose mirror use it is more loaded down with trivial details, must be one layer using process
How one layer of ground superposition spectacle frame, first do not discuss its effect, this mirror holder often adds one layer of spectacle frame just to produce two planes of refraction, two
Four planes of refraction of eyeglass, its optical property is changed certainly, and using effect is well imagined.In addition, rib lens combination eyeglass, on
Light region is myopia correction concavees lens, has prism in the border circular areas that lower smooth region concave lens surface is set, this Xia Guang area
Domain lens surface has substantially raised prism so that prism area is smaller, and prism centers prism degree hardly possible is searched, depending on nearly scope
It is small, poor appearance.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is：A kind of integral type bifocal rib lens, foundation are provided
Depending on the distance of thing, only need vertical to rotate and just may be selected corresponding dioptric area regarding thing, the tired of eyes is reduced to greatest extent
Labor.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of integral type bifocal rib lens, it is characterised in that：Eyeglass with integrative-structure, the eyeglass outer surface includes
The spherical cambered surface of two different curvatures and be respectively it is remote with dioptric area and closely use dioptric area, on the spherical cambered surface in the nearly use dioptric area
It is attached with the inside prism of substrate.
Described integral type bifocal rib lens, wherein：The eyeglass inner surface is monoblock type concave spherical surface or the recessed ball of monoblock type
Cylinder.
Described integral type bifocal rib lens, wherein：The remote use dioptric area is located above eyeglass, described near to use dioptric area
Positioned at the side-lower of eyeglass；There is the line of demarcation of square between the remote use dioptric area and the nearly area with dioptric.
The integral type bifocal rib lens that the utility model is provided use one-time cast-forming technique, form integral structure,
Compared with cemented type of the prior art, fusion type structure, Stability Analysis of Structures, wearing are safe, far determined with optics center, closely
It is stable, easy to use with prism set point.The utility model can also play the effect for slowing down myopia degree intensification.Moreover, passing through
Vertometer can find the ADD values of position designed by eyeglass；Prism degree and bottom to.In a word, the utility model product has user
Just, stable optical performance, ensure the advantages of prism substrate is inside.
Brief description of the drawings
Fig. 1 is the positive structure schematic for the integral type bifocal rib lens that the utility model is provided.
Description of reference numerals：1- far uses dioptric area；2- closely uses dioptric area.
Embodiment
Refer to shown in Fig. 1, be the front view for the integral type bifocal rib lens that the utility model is provided, it includes a pair of mirrors
Piece, the inner surface (towards the surface of wearer) of each eyeglass is the constant recessed spherical cambered surface of curvature, and outer surface includes two differences
The spherical cambered surface of curvature, is referred to as far to use dioptric area 1 near with dioptric area 2, in the present embodiment, the remote use dioptric area 1
Above eyeglass, the nearly use dioptric area 2 is positioned at the lower section of eyeglass, the remote use dioptric area 1 and closely with tool between dioptric area 2
There is the line of demarcation (remote different in the wall thickness of boundary line position from nearly dioptric area 2 with dioptric area 1, stepped) of square；And
And, described near with being attached with the inside prism of substrate on the spherical cambered surface in dioptric area 2.
Because the remote use dioptric area 1 with dioptric area 2 from closely having different curvature so that different above and below eyeglass formation
Diopter.The remote of eyeglass can be used for correction distant vision with dioptric area 1, it is adaptable to which wearer corrects distant vision；And the nearly use of eyeglass
Dioptric area 2 is synthetic prisms formula lens, and wearer serves reduction regulation by the region close eye and acted on set.By
In the prism that the additional substrate on the spherical cambered surface closely with dioptric area 2 is inside, the time of superposition glasses can be saved, it is to avoid frequently
Exchange the trouble of glasses, additionally it is possible to eyes " looking in the distance " will be changed " depending near " by lens optical performance, visual fatigue is reduced, to reach
The purpose of the occurrence and development of prevention/control adolescent myopia.
The integral type bifocal rib lens that the utility model is provided use one-time cast-forming technique, form integral structure,
It is near with compared with dioptric area 2 with the cemented type in existing product, fusion type structure eyeglass, it can detect all dioptrics using vertometer
Eyeglass is spent, and ensures that prism substrate is inside.
The utility model lens refractive power scope：Concave-sphere photometric range is -0.50Ds extremely -6.00Ds, post mirror photometric range
For -0.50Dc to -2.00Dc；Near is+1.50Ds to+3.00Ds with lower plus luminosity (ADD) scope in dioptric area 2, closely uses dioptric
Prism degree (P) scope in area 2 is 1.5~4.0 prism degrees.Prism degree (P) and lower plus luminosity (ADD) also can be specific according to wearer
Situation is selected.
Nearly use diopter=far use diopter+AAD.
Note is 1.：ADD values add the number of degrees of convex lens on the basis of far correcting defects of vision when representing to see near.
Example：Remote correct defects of vision -5.00DS, ADD=+1.50.
It is near to use diopter=- 5.00+1.50=-3.50DS.
It is near to use diopter=- 3.50DS.
