Description
Technical field
The invention belongs to optical lens technical field, more particularly to there are multiple focus areas, Mei Gejiao on one piece of lens
Point regional focus value is changing into the gradual change punktal lens being arranged in order.
Background technology
Chinese patent 201610092191.8《A kind of gradual change punktal lens》It is plane to provide a kind of lens base, another
Face is free form surface, and the free form surface is made up of concave surface, and is provided with some regions, and each area in the free form surface
The longitudinal length in domain is equal.The length in region is 0.1.0mm~100mm, and the refractive diopter in region is 1~2000 degree, diopter
Number is evenly distributed on lens, and each unit length etc. point distribution focus.
It is above-mentioned《A kind of gradual change punktal lens》Defect is the eyeglass of " free form surface " as the training of myopia correction, it is difficult to
The training method into rule being engaged with " free form surface " is set, and " free form surface " eyeglass can only be used as and be trained to people oneself hand
The eyeglass that work movement two lenses relative position is trained.And " free form surface " eyeglass does not point out the shape knot in " some regions "
Structure, the shape and structure for not knowing " some regions " are sphere, ellipsoidal surface or trapezoidal faces；The length in 0.1.0mm~100mm
The refractive diopter for spending region is 1~2000 degree, i.e., it is 1 that refractive diopter can not be realized in 0.1.0mm~100mm length areas
~2000 degree of change, the change for realizing that refractive diopter is 1~2000 degree in 0.1.0mm~100mm length areas is not indicated yet
What the structure of change is.So the technical scheme can not realize the effect of correction.
Chinese patent 201520246792.0《One kind can any focus-variable lens group》Provide one kind：One of every eyeglass
Surface is horizontal plane, and another surface of eyeglass is to meet the non-aqueous plane surface that mathematics changing rule height rises and falls；Described mirror
A peak and a minimum point are provided with the non-aqueous plane surface of piece；The peak of the non-aqueous plane surface of described eyeglass with most
Multiple optical centres of consecutive variations are evenly distributed between low spot, along the non-aqueous plane surface of eyeglass；Described multiple optical centres
Refractive diopter successively decrease successively or be incremented by.Defect is " the meeting mathematics changing rule " does not indicate it is what rule.Described
" being uniformly distributed an optical centre at interval of 1.0mm ", then the curved surface can only be spherical shape structure to an optical centre, and ball
Face shape and structure is difficult to the training function of vision correction, because the sight of human eye is to pass through eyeglass in a point, and eyeglass
In each interval be an optic center point, the two points of the point and optic center point of sight are difficult to overlap.So technology
Scheme can not realize the training of vision correction, can not realize thoroughly solve the problems such as asthenopia.And " non-aqueous plane surface "
Record does not indicate it is what curved surface.
The content of the invention
It is an object of the invention to provide a kind of two lenses group can be carried out regular zoom relative movement, two lenses group by motor
Regular diopter change can be produced, convenient with after computer program controlled motor, two lenses group can be produced and rectified by rule
Equidistant change punktal lens straight burr monolithic among the two lenses group used of positive eyesight.
The structure of the present invention：
Include for the equidistant change punktal lens straight burr monolithic in vision correction two lenses group, including lens straight burr monolithic
Two relative transparent surfaces, one is smooth even surface 1, and another is the more corrugated surfaces 2 of equidistant zoom；It is characterized in that：Deng
Formed side by side apart from the more corrugated surfaces 2 of zoom for multiple equidistant width bar shaped curved surfaces 3 are parallel, make the more corrugated surfaces 2 of equidistant zoom
Cross section into equidistant width zigzag structure,
Each the strip width d of equidistant width bar shaped curved surface 3 side by side is equal, and each strip width d scope is
0.1mm is to some value between 5.0mm；
The lens strength numerical value of same equidistant width bar shaped curved surface 3 is identical, and same equidistant width bar shaped is bent
Whole lens focus in face 3 are point-blank；
All the lens focus line of equidistant width bar shaped curved surface 3 is parallel to each other；
Lens strength numerical value extreme difference N is some value between 10 degree to 100 degree；
All equidistant width bar shaped curved surface 3 is arranged side by side, and lens strength numerical value extreme difference N is identical；
The lens straight burr monolithic body has while be eyeglass straight flange 4, any two neighboring equidistant width bar shaped curved surface 3 it
Between separator bar 5 it is vertical with eyeglass straight flange 4.
The same equidistant central shaft phase of width bar shaped curved surface 3 in the equidistant change punktal lens straight burr monolithic of the present invention
Vertical any cross section lens strength numerical value is identical, makes whole focuses of same equidistant width bar shaped curved surface 3 into one
Bar straight line, and this focus line and centerline axis parallel of same equidistant width bar shaped curved surface 3.
The purposes of the present invention：The equidistant change punktal lens straight burr monolithic of the present invention is this monolithic combination for two
The separate part used, combined method be by the present invention two straight burr monolithics smooth even surface 1 be affixed into it is gapless can
The mutually relative double-sheet arrangement mode slided uses.Two monolithics are mutually relative to be slided, and two straight burr monolithics are in different cunnings
Dynamic position just can produce different compound lens diopter numerical value.Trained for the zoom of an eyes, help has myopia
Patient recovers eyesight.So equidistant change punktal lens straight burr monolithic of the invention is the list with double-disk eyesight correcting glasses
Piece.
Because the lens focus line of the equidistant width bar shaped curved surface 3 of whole of the present invention is parallel to each other, in such use
Two described equidistant punktal lens straight burr monolithics that become are in different sliding positions, the two of relative position in two monolithics
Two equidistant width bar shaped curved surfaces 3 that individual equidistant width bar shaped curved surface 3, i.e. same eye sight line pass through could form one
The rod lens region of bar lens strength numerical value, it is same lens dioptric to make vision of the eyes in this rod lens region
