Description
Technical field
The present invention relates to a kind of half progressive lens and the glasses containing it.
Background technology
When a people due to the age increases and when eye adjusting force weakens, it is necessary to depending on remote and depending on closely making respectively
Vision correction, at this moment often need to wear use respectively with two pair of glasses, this with regard to very inconvenient, therefore generate by
Two kinds of different refractive power mills turn into the eyeglass in two regions, this eyeglass is referred to as double on same eyeglass
Light microscopic or bifocal slasses.But double light microscopics exist directly change from distance light area to the dipped beam area number of degrees, no mistake
Cross, because, there is image-jumping phenomenon in the optics area between not taking a fancy to, easily make the phenomenon of visual field loss, and by
Gradually substituted 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 areas
By gradual change passage until Jin Yong areas are incrementally increased.In the fifties, gradual change mirror is by entitled Essel at that time
French company issue first.Gradual change mirror is specially to design the eyeglass used to presbyope, is particularly possessed
It is other ametropia, it is necessary to wear glasses to correct the presbyope of distal and proximal eyesight, enable them all
Possess clearly vision in distance range.Look like monochromatic light mirror there is obvious point than those outside gradual change mirror
Boundary line and sub-pieces, and influence outward appearance double light microscopics or three light microscopics it is attractive in appearance a lot.As double light microscopics, gradual change
Mirror typically requires that wearer uses area appropriate on eyeglass at different distance vision (in closely, or remote)
Domain.
After ten thousand lis (Varilux) eyeglass of the first generation emerges, the design of gradual change mirror have passed through great
Improve：The problem of modern new lens design eliminates conventional ten thousand li, and be easily very popular institute
Wear.The creation target of lens designers is constantly updated for many years, this can change from the design of gradual change mirror and
See.Ten thousand li eyeglasses of the first generation are compared with the level of eyeglass today, it appears simple and crude and shortage, which is taken into account, matches somebody with somebody
The needs of wearer.The gradual change mirror design of the eighties becomes more ripe, forms the lens design of series.This
A little eyeglasses are to be specifically designed to give demand roomy read area, but are not intended to the use influenceed by marginal aberration
Person, other designs are more suitable for relatively doing more physical exercises, and the user for once experiencing aberration effects uses.Eyeglass
Designer think that substantially two kinds designs are to be combined into one, so they be different wearers set
Different eyeglasses is counted.
Newest gradual design possesses the deformation in wider read area and less marginal aberration area, and these set
Meter avoids in different life styles to a certain extent, uses the needs of different eyeglasses.
The shortcomings that gradual change mirror, is as follows：(1) area of intervening fade passage and Jin Yong areas both sides includes unnecessary
Astigmatism degree, therefore it is unsuitable for central vision, the suitable peripheral visual acuity running in these areas, and will not shadow
Ring locomitivity.(2) because some wearers are difficult in adapt to the peripheral region metaboly of eyeglass.If mirror
Testing for piece is matched somebody with somebody properly, and wearer obtains correct guidance when glasses are allotted, and this problem is few
Occur.Trendy gradual change mirror is easier to receive than old-fashioned design.(3) although new-type gradual change mirror is than old-fashioned
The gradual change mirror of design, which is easily tested, matches somebody with somebody, but they still need it is more accurate than double light microscopics and most monochromatic light mirrors
Assembling (except aspherical mirror).(4) gradual change mirror is also more expensive than double light microscopics, three light microscopics, monochromatic light mirror.
The content of the invention
The technical problems to be solved by the invention are to overcome the gradual change mirror of prior art adaptation process to be present
Long, the defects of dipped beam area visual field is small, and provide a kind of half progressive lens and the glasses containing it.The present invention
The advantages of double light microscopics of half gradual change mirror set and gradual change mirror for providing, it is more easily adapted to conform to than gradual change mirror.
The invention provides a kind of half progressive lens, its feature is that half progressive lens are included from upper
A Yuan Yong areas, a middle area and the Jin Yong areas being sequentially distributed under, the diopter in the Yuan Yong areas are to see
Remote diopter a, the diopter in the Jin Yong areas be see remote diopter a and near addition value ADD it
With, the diopter of the middle area is increased to the diopter a+ADD in Jin Yong areas by a+x gradual changes from top to bottom,
X therein is set according to the conventional intermediate distance of eyeglass user, it is assumed that the starting of conventional intermediate distance
It is worth for y rice, then x=1/y.
Identical with conventional gradual change mirror, half progressive lens also include two pieces of peripheral regions, and two pieces of peripheries are distinguished
Not Wei Yu half progressive lens the lower left corner and the lower right corner.
Remote optics area (Ji Yuanyong areas) sees near optics area (Ji Jinyong areas) to lower section seen from above
Distance --- i.e. progressive passage can be according to the inspection result of dispenser, self-defining.
ADD refers near addition value, that is, wear reading glasses when, see far with the difference for seeing near diopter,
The number of degrees of presbyopic are can be understood as, age, use when the value matches somebody with somebody mirror for doctor's optometry according to glasses user
The factors such as eye custom, eye regulating power determine.
Understanding for x values and y values, is illustrated below：It is assumed that the conventional medium spacing of eyeglass user
From for 2 meters to 30 centimetres, i.e., 2 meters are initial value, and 30 centimetres are end point values, then y values are just 2,
X values are just reciprocal for it, i.e., and 0.5.
In the present invention, described diopter has this area conventional sense, such as that often says see remote correction
The number of degrees are -300 degree, then see remote diopter a=-3.0D.
Present invention also offers a kind of glasses for including above-mentioned half progressive lens.
On the basis of common sense in the field is met, above-mentioned each optimum condition, it can be combined, produce this hair
Bright each preferred embodiments.
The positive effect of the present invention is：The adaptation process of half gradual change mirror provided by the invention compares gradual change
Mirror is short, is especially suitable for crowd that is older and wearing gradual change mirror for the first time, the crowd to gradual change mirror bad adaptability
And the crowd not high to part intermediate distance requirement.For example the distance between 5 meters to 2 meters is used
Few high age patient (over-65s), or when the patient at relatively low age wears this kind of eyeglass, can
Using the distance between compensatory 5 meters to 2 meters of the adjusting force of itself, can range use.
Brief description of the drawings
Fig. 1 is the structural representation of half progressive lens of the embodiment of the present invention 1；Wherein, 1 remote use is represented
Area, 2 represent middle area, and 3 represent Jin Yong areas, and 4 represent peripheral region.
Embodiment
The present invention is further illustrated below by the mode of embodiment, but is not therefore limited the present invention to
Among described scope of embodiments.The experimental method of unreceipted actual conditions in the following example, according to normal
Rule method and condition, or selected according to catalogue.
Embodiment 1
As shown in figure 1, half progressive lens that the present embodiment provides, including one be sequentially distributed from top to bottom
Yuan Yong areas 1, a middle area 2 and a Jin Yong areas 3, the diopter in the Yuan Yong areas 1 are to see remote dioptric
A is spent, the diopter in the Jin Yong areas 3 is to see remote diopter a and near addition value ADD sums, institute
The diopter for stating middle area 2 is increased to the diopter a+ADD in Jin Yong areas 3 by a+x gradual changes from top to bottom,
X therein is set according to the conventional intermediate distance of eyeglass user, it is assumed that the starting of conventional intermediate distance
It is worth for y rice, then x=1/y.
Identical with conventional gradual change mirror, half progressive lens also include two pieces of peripheral regions 4, two pieces of peripheral regions
4 are located at the lower left corner and the lower right corner of half progressive lens respectively.
Effect example 1
For the user of 62 years old, the daily main closely sighting target seen within 1m~30cm.Press
The prescription that conventional gradual change mirror tests method of completing the square inspection is：- 3.50DS -1.0ADD+2.75D is (i.e.
0~+2.75=2.75D).Wherein, DS is meant that concave-sphere, and -3.50D, which refers to, sees that the remote number of degrees are 350 degree,
1.0 refer to the degree of correction, and presbyopic near addition value ADD is 2.75D, if gradual change mirror, that
The diopter of middle area then from -3.50D gradual transitions to -0.75D (i.e. -3.50DS ADD+2.75D),
Because ADD is big, aberration is big caused by eyeglass, it is not easy to adapts to.
When user wears such gradual change mirror：See identical with monochromatic light mirror at a distance, needed when seeing 5m~1m
Using 0~1.0D regulation, it can usually pass through the compensatory part of regulation of itself eye.
It is if the half gradual change mirror with the embodiment of the present invention 1 is tested：It is 1D that 1m regulation, which stimulates, so
Y values are that 1, x values are 1, then become gradual change mirror middle area diopter then from -2.50D (i.e.
- 3.50D+1.00D) to -0.75D (i.e. -3.50DS ADD+2.75D), prescription is gradual transition：
- 3.50DS -1.0ADD+1.00D~+2.75D.
When seeing within 1m, regulation compensation is obtained using the ADD of half gradual change mirror, due to half gradual change mirror
The changing value of the diopter of middle area is only+1.75D, is reduced than full gradual change mirror (+2.75D), so
See that the near region visual field adds, aberration reduces, it is easier to adapts to.
