Abstract
The utility model relates to a core zoom glass piece, characterized by: circular lens no. 1 is equipped with the core on the surface and zooms the region, and this region diameter is not more than 35mm, and processing has the sphere ring of 20 above luminosity gradual changes in the core zooms the region, and the projection of plural number way sphere ring has the same centre of a circle, cutting vision correction lens effective coverage contains core over half and zooms the region. The utility model discloses what fully the consideration was actually worn glasses get used to with the eye, lifts often soon far, hangs down and watches near state, combines the gradual change lens to make to and with cut out the relation of correcting lens effective coverage, the core zoom glass piece of design only is being not more than the gradual change of 35mm core space intra -area, satisfies and observes the image by the far away and nearly correction process that corresponds the gradual change, realizes automatically zoom's purpose, both can be used for processing preparation hyperopia lens, also can be used for preparing the concave lens, and especially can effectively avoid myopia to deepen.
Description
Technical field:
This utility model belongs to eyeglass field of correcting defects of vision, particularly to a kind of core Zoom glasses sheet.
Background technology:
Existing progressive focus-variable lens is used on presbyopic glasses, and solution need to carry the trouble of many pair of glasses；But regardless of presbyopia or concave lens, right and left eyes both sides all produces serious blind area, do not see Chu Zaocheng deteriorating vision, drive and the dangerous factor of stair activity.And in adolescent myopia field, all do not adopt gradual change way, owing to teenager eyeball function is good, self-care regulating power is strong, adapts to see near and see remote adjustment.Therefore, it is also to see for the purpose of far clearly that myopia joins mirror optometry, namely ensure attending class look at the blackboard can know for want, and between using in a large number at the moment, namely it is in-plant do one's assignment and read a book, if still using the glasses attended class, after the some time, as reduced vision can be caused again after halves, again wear deeper of glasses again.It may be said that progressive lens is applied in myoporthosis field, can reach to prevent the physiology purpose of myopia development, and in the use in hypermetropia field, it is only for few band a pair of glasses, therefore progressive lens should have more wide market in myopia field.For this dealer at CN204101833U, open one prevention slows down myopia development eyeglass, its structure is that eyeglass is designed to see far field from top to bottom successively, take a fancy to from district and see near region, organically eyeglass is divided three different luminosity regions, and can the custom of utilization eye, look up the natural action far leaned over a book, become what have deeper luminosity to see far field in eyeglass upper design, middle part down gradually becomes shallower as, and eyeglass bottom is the near region of seeing of either shallow luminosity, ensure myope's eye hygiene, coordinate people's ocular accommodation, it is finally reached the purpose that retarding myopia is deepened or worsened.This principle is also applied for presbyopic glasses, also can solve the trouble with many pair of glasses.This eyeglass principle is plain, but manufacture difficulty is big.How to research and develop a kind of eyeglass that there is gradual change and be prone to processing, namely become the object of this utility model research.
Summary of the invention:
The purpose of this utility model is that design is a kind of in the 35mm nucleus on one surface of circular eyeglass, and processing has the core Zoom glasses sheet of complex trace luminosity gradual change Spherical Ring.
Technical solutions of the utility model are achieved in that a kind of core Zoom glasses sheet, it is characterized in that: circular eyeglass one surface is provided with core zoom area, this regional diameter is not more than 35mm, in core zoom area, processing has the Spherical Ring of the 20 above luminosity gradual changes in road, and the projection of complex trace Spherical Ring has the same center of circle；Cutting vision correction lens effective coverage comprises more than half core zoom area.
The light number of degrees of every one Spherical Ring of described core zoom area are between 1 to 9.
The described core zoom area from-inner-to-outer light number of degrees taper into, and are zero diopter district outside this region.
The described core zoom area from-inner-to-outer light number of degrees become larger, and are the maximum rectification light number of degrees outside this region.
Another surface of described circular eyeglass keeps complete recessed bent face.
Described core zoom area accounts for the area of 2/1sts to three/2nd eyeglass effective coverages.
This utility model take into full account actual wear glasses be accustomed to eye, lift remote soon often, vertical near soon state, make in conjunction with progressive lens, and with cut out the relation of correcting lens effective coverage, the core Zoom glasses sheet of design, only being not more than gradual change in 35mm nucleus, meet and observe image by the far correcting process of nearly corresponding gradual change, it is achieved the purpose of autozoom；Both can be used to processing and fabricating hyperopic lens, it is possible to be used for preparing concave lens, especially can be prevented effectively from myopia development.

Detailed description of the invention:
With reference to Fig. 1, core Zoom glasses sheet, it is provided with core zoom area 2 on circular eyeglass 1 one surface, this regional diameter D is not more than 35mm, in core zoom area 2, processing has the Spherical Ring 3 of the 20 above luminosity gradual changes in road, can reaching at most 99 roads, the projection of complex trace Spherical Ring 3 has the same center of circle；Cutting vision correction lens effective coverage 4 comprises more than half core zoom area 2, and the public center of circle of core zoom area 2 is in the position on the upper side of eyeglass effective coverage 4, in other words, in eyeglass effective coverage 4, core zoom area 2 accounts for 2/1sts to three/2nd areas.This also complies with people and wears glasses and be accustomed to eye, wears glasses and often slides down from the bridge of the nose, and now the center of circle of Spherical Ring 3 is just at people pupil center at eye level, namely looks squarely and sees remote angle, and just at the people region depending on closely relating to outside core zoom area 2.
Further, the light number of degrees of every one Spherical Ring 3 of core zoom area 2 are between 1 to 9, and the number of channels of Spherical Ring 3 is more many, the light number of degrees of gradual change can be more low, as design has 99 road Spherical Rings, the gradual change light number of degrees of per pass Spherical Ring take 1 degree, and core zoom area 2 just has the luminosity gradual change of 99 degree；If taking 20 road Spherical Rings 3, the per pass gradual change light number of degrees take 9 degree, and core zoom area 2 can reach the fade effect of 180 degree.
With reference to Fig. 2, for the application example of presbyopic lens, the core zoom area 2 from-inner-to-outer light number of degrees become larger, and are the maximum rectification light number of degrees outside this region.Eyeglass effective coverage 4 after cutting, when looking squarely namely look remote, almost can correct, and by the near conversion of hypermetropia, correcting the light number of degrees is gradually increased, and meets the demand of presbyopia correction.
With reference to Fig. 3, for the application example of concave lens, the core zoom area 2 from-inner-to-outer light number of degrees taper into, and are zero diopter district outside this region.Also comply with bathomorphic eye muscle regulation mechanism, and prevention myopia development is had obvious effect.
Complete recessed bent face is kept, in order to process astigmatism on another surface of above-mentioned circular eyeglass 1.
