Description
Technical field
This utility model is related to a kind of half progressive lens and contains its glasses.
Background technology
When because the age increases, eye adjusting force weakens a people it is necessary to rectify to depending on remote with depending on closely making vision respectively
Just, at this moment often need to join two pair of glasses and wear use respectively, this is just very inconvenient, therefore create by two kinds of different refractive powers mills with
On one eyeglass, become the eyeglass in two regions, this eyeglass is referred to as double light microscopics or bifocal glassess.But double light microscopics exist from
Distance light area directly changes to the dipped beam area number of degrees, no transition, because the light school district between not taking a fancy to, has image-jumping phenomenon, easily makes to regard
The wild phenomenon lost, and gradually replaced by gradual change mirror.
So-called gradual change mirror, is a kind of eyeglass exclusively for presbyope's design, and the number of degrees of eyeglass are along Yuan Yong area through gradual change
Passage is until Jin Yong area is incrementally increased.In the fifties, gradual change mirror is issued first by the French company of entitled Essel at that time.Gradually
Becoming mirror is specially to design the eyeglass using to presbyope, particularly has other ametropia, needing wears glasses to correct remote and
The presbyope of near vision, enables them to have clearly vision in all of distance range.Look like monochromatic light outside gradual change mirror
Mirror, has obvious demarcation line and a sub-pieces than those, and affects double light microscopics of outward appearance or three light microscopics are attractive in appearance a lot.As double light microscopics one
Sample, gradual change mirror typically requires wearer when different distance vision (in closely, or remote) using suitable region on eyeglass.
After ten thousand lis (Varilux) eyeglass of the first generation emerges, the design of gradual change mirror have passed through great improvement：Existing
The new lens design in generation eliminates the problem of conventional ten thousand lis, and is very easily worn by masses.The wound of lens designers
Make target to constantly update for many years, this can change from the design of gradual change mirror and see.Ten thousand li eyeglasses of the first generation and eyeglass today
Level compare, it appears simple and crude and lack the needs taking wearer into account.The gradual change mirror design of the eighties becomes more ripe, shape
Become the lens design of series.These eyeglasses are to be specifically designed read area roomy to demand, but are not intended to by marginal aberration shadow
The user ringing, other designs are more suitable for relatively doing more physical exercises, and the user once experiencing aberration effects is used.The design of eyeglass
Person thinks that substantially two kinds designs are to unite two into one, so they devise different eyeglasses for different wearers.
Up-to-date gradual design has wider read area and the deformation in less marginal aberration area, and these designs are certain
Avoid in different life style in degree, using the needs of different eyeglasses.
The shortcoming of gradual change mirror is as follows：(1) area of intervening fade passage and Jin Yong area both sides comprises unnecessary astigmatism degree,
Therefore it is unsuitable for central vision, the suitable peripheral visual acuity running of these areas, and do not interfere with motor capacity.(2) because of some
Wearer is difficult in adapt to the Zhou Bianqu metaboly of eyeglass.If the cooperation of testing of eyeglass is fitted, and wearer is when glasses are allotted
Obtain correct guidance, this problem is few appearance.Trendy gradual change mirror is easier to accept than old-fashioned design.(3) although
New-type gradual change mirror is joined than easy the testing of gradual change mirror of old-fashioned design, but they need for than double light microscopics with most monochromatic light mirrors more
Accurately assembling (except aspherical mirror).(4) gradual change mirror is also expensive than double light microscopics, three light microscopics, monochromatic light mirror.
Utility model content
The technical problems to be solved in the utility model is to overcome the gradual change mirror of prior art to there is adaptation process length, near
The little defect in the Guang Qu visual field, and provide a kind of half progressive lens and contain its glasses.The half gradual change mirror that this utility model provides
Gather double light microscopics and the advantage of gradual change mirror, be more easily adapted to conform to than gradual change mirror.
This utility model is to solve above-mentioned technical problem by following technical proposals：
This utility model provides a kind of half progressive lens, and its feature is, described half progressive lens are included from top to bottom
A Yuan Yong area, a mesozone and the Jin Yong area being sequentially distributed, the diopter in described Yuan Yong area is to see remote diopter a, described
The diopter in Jin Yong area is to see remote diopter a and near addition value ADD sum, and the diopter of described mesozone is from top to bottom by a+
X gradual change increases to the diopter a+ADD in Jin Yong area, and x therein is according to the conventional intermediate distance setting of eyeglass user it is assumed that often
The initial value of intermediate distance is y rice, then x=1/y.
Identical with conventional gradual change mirror, described half progressive lens also include two pieces of Zhou Bianqu, and Liang Kuai periphery area is located at institute respectively
State the lower left corner and the lower right corner of half progressive lens.
The distance that near light school district (Ji Jinyong area) is seen to lower section in light school district (Ji Yuanyong area) remote seen from above is
Progressive passage can be according to the inspection result of dispenser, self-defining.
ADD refers near addition value, that is, when wearing reading glasses, see remote with see near dioptric difference it can be understood as
The number of degrees of presbyopia, this value for doctor's optometry join during mirror according to age of glasses user, with eye custom, eye regulating power etc. because
Element determines.
For the understanding of x value and y value, it is illustrated below：It is assumed that the conventional intermediate distance of eyeglass user is 2 meters to 30
Centimetre, that is, 2 meters is initial value, and 30 centimetres is end point values, then y value just for 2, x value just for its inverse, that is, 0.5.
In this utility model, described diopter has this area conventional sense, and that for example often says sees the remote rectification number of degrees
For -300 degree, then see remote diopter a=-3.0D.
This utility model additionally provides a kind of glasses comprising above-mentioned half progressive lens.
Positive effect of the present utility model is：The adaptation process of the half gradual change mirror that this utility model provides compares gradual change
Mirror is short, is especially suitable for older and wears the crowd of gradual change mirror, the crowd to gradual change mirror bad adaptability and in partly for the first time
Between apart from the not high crowd of use requirement.Such as the distance between 5 meters to 2 meters is used few high age patient (65 years old with
On), or when the patient at relatively low age wears this kind of eyeglass, the distance between compensatory 5 meters to 2 meters of the adjusting force of itself can be used,
Can range use.
Brief description
Fig. 1 is the structural representation of half progressive lens of this utility model embodiment 1；Wherein, 1 Yuan Yong area, 2 representatives are represented
Mesozone, 3 represent Jin Yong area, and 4 represent Zhou Bianqu.
Specific embodiment
Name a preferred embodiment, and combine accompanying drawing to become apparent from intactly illustrating this utility model.
Embodiment 1
As shown in figure 1, half progressive lens that the present embodiment provides, including the Yuan Yong area 1, being sequentially distributed from top to bottom
Mesozone 2 and a Jin Yong area 3, the diopter in described Yuan Yong area 1 is to see remote diopter a, and the diopter in described Jin Yong area 3 is to see
Remote diopter a and near addition value ADD sum, the diopter of described mesozone 2 increases to Jin Yong area by a+x gradual change from top to bottom
3 diopter a+ADD, x therein are according to the conventional intermediate distance setting of eyeglass user it is assumed that the rising of conventional intermediate distance
Initial value is y rice, then x=1/y.
Identical with conventional gradual change mirror, described half progressive lens also include two pieces of Zhou Bianqu 4, and two pieces of Zhou Bianqu 4 are located at respectively
The lower left corner of described half progressive lens and the lower right corner.
Effect example 1
For the user of 62 years old, the daily closely sighting target mainly seen within 1m～30cm.Routinely gradual change mirror
The prescription testing method of completing the square inspection is：- 3.50DS 1.0ADD+2.75D (i.e. 0～+2.75=2.75D).Wherein, DS is meant that
Concave-sphere, -3.50D refers to see that the remote number of degrees are 350 degree, and 1.0 refer to the degree corrected, and presbyopic near addition value ADD is 2.75D,
If gradual change mirror, then the diopter of mesozone is then from -3.50D gradual transition to -0.75D (i.e. -3.50DS ADD+
2.75D), because ADD is big, the aberration that eyeglass produces is greatly it is not easy to adapt to.
When user wears such gradual change mirror：See identical with monochromatic light mirror at a distance, see and need using 0～1.0D during 5m～1m
Regulation, usually can be by the compensatory part of regulation of itself eye.
If testing the half gradual change mirror joining this utility model embodiment 1, it is：It is 1D that the regulation of 1m stimulates, so y value is 1, x
It is worth for 1, then the diopter of mesozone becoming gradual change mirror is then from -2.50D (i.e. -3.50D+1.00D) gradual transition to -0.75D
(i.e. -3.50DS ADD+2.75D), prescription is：- 3.50DS 1.0ADD+1.00D～+2.75D.
When seeing within 1m, obtain to adjust using the ADD of half gradual change mirror and compensate, due to the diopter of the mesozone of half gradual change mirror
Changing value be only+1.75D, decrease than full gradual change mirror (+2.75D), so seeing that the near region visual field increased, aberration decreases,
It is more easily adapted to conform to.
