Description

一种动力渐进多焦点镜片 A power progressive multifocal lenses

技术领域 FIELD

[0001] 本发明涉及镜片技术领域,特别是涉及一种动力渐进多焦点镜片。 [0001] The present invention relates to the field lens, in particular, it relates to a power progressive multifocal lenses.

背景技术 Background technique

[0002] 长期以来戴眼镜者都是以单焦点镜片为主。 [0002] For a long time wear glasses are dominated by single-vision lens. 单焦点镜片都是靠眼睛的睫状肌来调节眼睛和物体的距离,眼睛长时间或者频繁的用睫状肌调节,容易使眼睛处于疲劳状态, 长期以往眼睛就会加深近视或者老花。 Monofocal lenses are relying on the ciliary muscle of the eye to adjust the distance between the eyes and the object of frequent or prolonged eye with ciliary muscle, makes the eyes in fatigue, long past the eyes will myopia or presbyopia. 渐进多焦点镜片的出现解决了靠眼睛调节的现象, 它是靠镜片上不同的焦点来调节。 Progressive multifocal lens appears solved by adjusting the eye phenomenon, it is by a different lens to adjust the focus. 渐进多焦点镜片是一种上方用于看远,下方用于看近,上下度数不同的镜片。 It is a progressive multifocal lens used to see far above, see below for the past, different uplink power of the lens. 从镜片上方固定的远用度数到镜片下方固定的近用度数不是突然改变的,而是在两者之间通过屈光力循序渐进变化而逐渐过渡的。 Above the distance power of the lens is fixed to the lower lens fixed near dioptric power is not suddenly changed but rather a gradual transition between the two by a gradual change from the refractive power. 渐进多焦点镜片包括远用光区、过渡光区、近用光区和晃动区。 Progressive multifocal lenses include much light, transition zone, near light district and shaking zone. 从架置于人眼上的渐进多焦点镜片角度来看,远用光区位于镜片上部,近用光区位于镜片下部,远用光区和近用光区之间通过过渡光区过渡。 The progressive multifocal lens holder is placed on the angle of view of the eye, much light in the upper region of the lens, is located near the lower portion of the lens optical region, much light by a transition zone between the transition region and the near optical zone. 远用光区、近用光区和过渡光区的弧形边界共同在渐进多焦点镜片中部围成一个区域,而在该区域朝向镜片边缘的两侧为晃动区。 Much light region, arcuate boundary of the transition region and the near optical zone on both sides of a common progressive multifocal lens surrounded by a central region, in the region facing the lens edge region is shaking. 渐进多焦点镜片在视觉范围的各个距离都可获得清晰的视力,既满足了远用,又满足了近用以及中间各个距离的使用。 Progressive multifocal lenses in all are available from the visual range of clear vision, both to meet the distance, but also to meet the near distance and the use of each of the middle. 渐进多焦点镜片解决了那些既有老光又有近视;既有远视又有老光的特殊人群的眼镜配戴,一副眼镜即可满足所有的需求。 Progressive multifocal lenses solves both of those old light have myopia; hyperopia glasses both have old people wear special light, a pair of glasses to meet all needs.

[0003] 传统的渐进多焦点镜片可分为软性设计和硬性设计两种。 [0003] The conventional progressive multifocal lenses can be divided into two kinds of soft design and rigid design. 软性设计中远用光区到近用光区的过渡通道较长,一般为17_、18_,设计通道内的焦点较多光度变化较小,但是近用光区的有效使用范围很小,容易使人眼通过晃动区去看事物,从而造成图像扭曲。 COSCO flexible design to near optical light path longer transition zone, generally 17_, 18_, more smaller changes in the focus of luminosity channel design, but the effective range of the near optical zone is small, easy to the human eye to see things through shaking zone, resulting in image distortion. 硬式设计中远用光区到近用光区的过渡通道较短,通道内焦点少,容易造成跳像现象,佩戴者的适应时间长。 Rigid design COSCO light to near light transition zone of shorter passages, less focus within the channel, making it easy to jump like a phenomenon, long time to adapt to the wearer. 软式设计和硬式设计需要生产很多的模具以满足不同人群的需求,对佩戴者的验光和装配要求极高。 Soft design and production requires a lot of hard mold design to meet the needs of different groups, the wearer of optometry and assembly demanding.

[0004] 可见,现有的渐进多焦点镜片一方面,由于近光区的有效范围小造成人眼通过晃动区去看事物,从而使得图像扭曲;另一方面,由于镜片的过渡通道较短,通道内焦点少而容易产生跳像。 [0004] visible, conventional progressive multifocal lenses on the one hand, due to the small effective range of the near zone of the human eye to see things caused by shaking zone, so that the image distortion; on the other hand, since the lens is short transition duct, less likely to occur within the channel hop focus image.

具体实施方式 detailed description

[0078] 为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。 [0078] For the above-described objects, features and advantages of the invention more apparent, the accompanying drawings and the following specific embodiments of the present invention will be further described in detail.

[0079] 实施例一 [0079] Example a

[0080] 参照图1,示出了本发明一种动力渐进多焦点镜片的结构图。 [0080] Referring to FIG 1, illustrates a progressive power multifocal lens according to the present invention, the structure of FIG.

[0081] 本实施例中的动力渐进多焦点镜片采用渐进多焦点的中性化设计而成,包括:远用光区102、近用光区104、过渡光区106和晃动区108,其中,远用光区102与近用光区104 之间为过渡光区106,过渡光区的两侧为晃动区108。 [0081] The embodiment of the present embodiment power progressive multifocal lenses using the neutral multifocal progressive designed, comprising: a light far regions 102, 104 near optical zone, the transition zone 106 and shaking region 108, wherein, much light between region 102 and region 104 near optical zone 106 on both sides of the transition, the transition zone 108 is a zone shaking. 过渡光区106为动力渐进多焦点镜片从远用光区至近用光区的过渡通道。 The transition zone 106 is powered progressive multifocal lens light far from the channel region to the transition region near the light. 动力渐进多焦点镜片的远用光区102只有一个稳定的光度,可以看清楚远处的事物;近用光区也只有一个稳定的光度,只可以看清楚近处的事物;过渡光区106是一段人眼通过远用光区看事物过渡到通过近用光区看事物时的一个过渡区域,在这个区域中,镜片度数有规律变化的,通过这个区域人眼可以看清楚中距离的事物;晃动区108是光度变化的区域,通过该区域看东西人眼会感到模糊。 Progressive power multifocal lenses much light region 102 is only one stable brightness can see the distant object; only a region near a light stable luminosity, can only see things near; transition zone 106 is a period of transition to the human eye sees things at a transition area by nearly run out of things to see much light district by district, in this region, regularly changing lenses, through this region of the human eye can see things in the distance; shaking the region 108 is a region luminosity changes to see what the human eye through the region will feel fuzzy.

[0082] 本实施例中描述了动力渐进多焦点镜片在0. 5散光面型弧度间的过渡光区、近用光区、以及远用光区。 [0082] The present embodiment described the progressive multifocal lens power in the transition zone between the cylindrical surface type 0.5 radians, near light region, and much light region. 需要说明的是,0.5散光面只是一个测量时选择的散光面,也可以选取I. 0散光面型弧度间的过渡光区或其他散光面型弧度间的过渡光区。 Incidentally, when the selection is just a cylindrical surface measuring 0.5 cylindrical surface, you can also select I. 0 transition zone between the cylindrical surface curvature or other type transition zone between the cylindrical surface type arc. 之所以选择0. 5散光面,是因为在〇. 5散光面型弧度间的过渡光区为人眼能够接受的范围,即不会感到不舒适的范围。 Chose 0.5 astigmatism face, because in the transition zone between the square. 5 astigmatism type surface curvature of the human eye can accept a range that does not feel comfortable range. 随着散光面度数的增加其过渡区域也会变大,但是人眼去看事物时不舒适度也会越强。 With the increase of the degree of astigmatism face of its transition area also become large, but not the comfort of the human eye to see when things will be more strong.

[0083] 动力渐进多焦点镜片的配镜十字110位于动力渐进多焦点镜片的几何中心水平线112的中垂线的远用光区侧,与几何中心水平线112之间的距离为4毫米;其中,由于镜片出厂时都是圆形的,并且都具有上述五个光区,为了便于配镜,设计者会为镜片设置几何中心水平线112,镜片的几何中心水平线112是沿镜片的直径设置的,设置时使镜片的远用光区102与近用光区104分别位于几何中心水平线112的两侧。 [0083] Dynamic fitting cross of a progressive multifocal lens 110 is the power of the progressive multifocal lens geometric center of the horizontal line perpendicular much light region 112 side, the distance between the geometric center of the horizontal line 112 is 4 mm; wherein, Since both circular and having the above-described five zones, for convenience of glasses, a designer sets the geometric center of the horizontal line 112 of the lens, the geometric center of the lens 112 is a horizontal line along the diameter of the lens set, the factory setting of the lens when the lens optical region 102 and distal region 104 with light near the geometric center of each side of the horizontal line 112. 远用光区102的参考点114位于几何中心水平线112的中垂线上,与几何中心水平线112之间的距离为8毫米;近用光区104的参考点116与几何中心水平线112之间的距离为12毫米,正常佩戴时,近用光区的参考点116偏向鼻梁方向与几何中心水平线的中垂线之间的距离为2. 5毫米。 Light far reference point 114 is located on the region 102 in the vertical geometric center of the horizontal line 112, the horizontal distance between the geometric center 112 is 8 mm; light region near the reference point 104 and 116 between the geometric center of the horizontal line 112 distance of 12 mm, normal wear, the reference point of the near optical zone 116 toward the perpendicular distance between the geometric center of the horizontal direction of the nose is 2.5 mm. 由于人眼在使用远用光区视远时,瞳孔是放大的,而在使用近用光区视近时,瞳孔并不需要放大,因此本实施例中的渐多焦点镜片设置了阅读点位移,且大小为2. 5毫米。 Since the human eye using the time zone as far much light, the pupil is enlarged, whereas when using the near optical zone near vision, the pupil does not need amplification, and thus the present embodiment is provided to read an increasing focus lens displacement , and a size of 2.5 mm. 在正常佩戴眼镜时,左右镜片的近用光区的参考点都偏向鼻梁方向2. 5毫米。 In normal wearing glasses, the left and right optical lenses region near the reference point are 2.5 mm toward the direction of the nose.

[0084] 动力渐进多焦点镜片的过渡光区106在0. 50散光面型弧度间的长度为16毫米, 过渡光区106在0.50散光面型弧度间的平均宽度范围为4. 2至12. 5毫米;其中,动力渐进多焦点镜片的过渡光区并不是规则的区域,并不是一个长方形区域,因此其宽度并不均匀。 [0084] The progressive power multifocal lens length of the transition zone 106 between the cylindrical surface type 0.50 radians 16 mm, the transition zone 106 between the average width of 0.50 radians cylindrical surface type from 4.2 to 12. 5 mm; wherein the transition zone is not the progressive power multifocal lens rule a region, not a rectangular region, the width is not uniform. 随着与几何中心水平线之间距离的变化,过渡光区的宽度也会变化,例如:在距离几何中心水平线距离为8毫米处过渡光区的宽度为7. 4毫米,而距离几何中心水平线距离为12 毫米处过渡光区的宽度则为11. 8毫米。 With the change in the distance between the geometric center of the horizontal line, the width of the transition zone will change, for example: the transition zone width is 7.4 mm at 8 mm distance from the geometric center of the horizontal line, while the horizontal distance from the geometric center width of the transition zone of 12 mm compared to 11.8 mm. 因此,本实施例中运用平均宽度对过渡光区进行描述。 Accordingly, in the present embodiment using the average width of the transition zone of the embodiment will be described. 其中,平均宽度是通过对距离几何中心水平线不同距离处的过渡光区的宽度进行取值, 将这些宽度值求平均得到的。 Wherein the average width is the value of the width of the transition zone through at different distances from the geometric center of the horizontal line, the width of these obtained values ​​are averaged. 一种优选的取值方式为:分别取几何中心水平线之上4毫米处、几何中心水平线处、几何中心水平线之下4毫米、8毫米以及12毫米处的过渡光区的宽度值,将这些宽度值计算平均值得到过渡光区的平均宽度。 A preferred embodiment of the values: were taken at 4 mm above the geometric center of the horizontal line, at the geometric center of the horizontal line, the horizontal line below the geometric center of the 4 mm, 8 mm and a width value of the transition zone 12 mm, the width of these value is calculated to obtain the average of the width of the transition zone.

[0085] 动力渐进多焦点镜片的近用光区104在0. 50散光面型弧度间的最小宽度范围为5. 6至13. 1毫米,相对应的最大宽度范围为9. 1至16. 5毫米。 [0085] The progressive power multifocal lens light near region 104 in a range between a minimum width of the cylindrical surface type 0.50 radians from 5.6 to 13.1 mm, corresponding to the maximum width in the range 9.1 to 16. 5 mm. 其中,这些宽度范围值是通过对各个不同前弯度不同下加光度的动力渐进多焦点镜片的近用光区的最小宽度以及最大宽度值进行统计后得到的。 Wherein the width of the statistical values ​​by the maximum width and the minimum width value of the power addition value different front camber various progressive multifocal lens light region near obtained. 每一个动力渐进多焦点镜片的近用光区都对应一个最小宽度以及一个最大宽度。 Each progressive power multifocal lens corresponds to a near optical zone minimum width and a maximum width. 如,最小宽度为5. 6毫米时,其对应的最大宽度为9.1毫米。 When such a minimum width of 5.6 mm, which corresponds to the maximum width of 9.1 mm. 再如,最小宽度为13. 1毫米时,其对应的最大宽度为16. 5毫米。 Again, the minimum width is 13.1 mm, the maximum width of which corresponds to 16.5 mm. 并且,在统计各个动力渐进多焦点镜片的近用光区的最小宽度值、最大宽度值得同时,还计算了各个动力渐进多焦点镜片的过渡光区的平均宽度值,将各个动力渐进多焦点镜片的过渡光区的平均宽度进行统计得到了本实施例中所描述的过渡光区的平均宽度范围。 Further, in the light zone near the minimum width value of each of the statistical power of the progressive multifocal lenses, the maximum width worth while also calculating a progressive average value of the width of the transition zone of each lens focal power, the power of each progressive multifocal lenses the average width of the transition zone to obtain a statistical average width of the transition zone is described in the present embodiment. 动力渐进多焦点镜片的远区角度在0.50 散光面型弧度间为176至184度。 Progressive power multifocal lenses between the far-field angle of 0.50 radians cylindrical surface type of 176-184 degrees. 其中,远区角度为人眼通过动力渐进多焦点镜片看远处事物时在远用光区的可视角度。 Among them, the far-field angle for people viewing angle in the far zone of light when power progressive multifocal lens to see distant things through the eye. 本实施例中的动力渐进多焦点镜片测量得到的远区角度为180度,测量工差为+ /-4度,远用光区为180度表明该动力渐进多焦点镜片的远用光区无盲区,是可以充分利用的。 Far-field angular momentum in the present embodiment the progressive multifocal lens was measured to be 180 degrees, difference measurements workers + / -4 degrees, 180 degrees much light indicates that the region is a progressive power multifocal lens area without much light blind, we can take full advantage of.

[0086]本实施例中的动力渐进多焦点镜片,在0. 5散光面型弧度间依然具有平均宽度为4. 2至12. 5毫米的过渡光区;近用光区的最小宽度范围为5. 6至13. 1毫米,相对应的最大宽度范围可达9. 1至16. 5毫米,近用光区的有效使用面积大,通过比传统更大面积的近用光区,避了免人眼通过晃动区去看事物而造成的图像扭曲。 [0086] Examples of the present embodiment power progressive multifocal lens, the surface astigmatism between 0.5 radians type still have an average width of 4.2 to 12.5 mm of the transition zone; the minimum width of the near optical zone from 5.6 to 13.1 mm, corresponding to the maximum width of up to 9.1 to 16.5 mm, the effective use of a large area near light region by a larger area than the traditional area near light, to avoid the Free eye by distorting the image area to see things shaking caused. 同时,本实施例中的动力渐进多焦点镜片的过渡光区长度的设计为16毫米,这样的设计使得保证过渡光区面积较大的同时,过渡光区内的焦点数目适中。 Meanwhile, in the progressive power zone embodiment the length of the transition multifocal lens design of the present embodiment 16 mm, this design makes the transition zone to ensure a large area at the same time, the number of focus light transition zone is moderate. 避免了硬式设计中,将过渡光区的长度设计的较短例如将过渡光区长度设计成14毫米,而带来的过渡光区内焦点较少的问题,保证了渐进多焦点的镜片的度数是循序渐进均匀的变化的,人眼在看事物的时候不会产生跳像。 Avoiding the less hard design, the length of the transition zone is designed, for example, shorter length of the transition zone is designed to 14 mm, the light transition area brought focus to ensure that the degree of progressive multifocal lenses uniform change is gradual, the human eye when looking at things like no jumping. 通过本实施例中的动力渐进多焦点镜片,解决了现有的多焦点镜片中存在的图像扭曲或跳像的问题。 By the present embodiment the power progressive multifocal lenses, solve the image distortion in the conventional multifocal lens hop problems occurring or image. 此夕卜,本实施例中的动力渐进多焦点镜片,在保证了人眼看事物时不会造成图像扭曲和跳像的同时,远区角度可达到180度,具有宽阔的远用光区,使人眼拥有更宽的视远区域。 Bu this evening, the embodiment power progressive multifocal lens of the present embodiment, in ensuring the jump will not cause image distortion and image at the same time, far-field angle of up to 180 degrees to the human eye things much light having a wide area, so that the human eye has a far wider view area. 由于本发明中的动力渐进多焦点镜片具有宽阔的视远区域以及视近区域,因此即便是配镜者在运动或开车时,人眼依然不会偏离镜片的有效区域,依然可以通过视近区域去看近处事物, 通过视远区域去看远处的事物。 Since the power of the progressive multifocal lens of the present invention have a wide far vision region and a near vision region, so even when the glasses are effective region or motion drive, still without departing from the eye lens, the near vision zone can still to see near things, see things through as far distant region. 本发明中的动力渐进多焦点镜片不仅可以满足传统的渐进多焦点镜片在配镜者处于静态环境下即看报或者看黑板等时佩戴,还可以满足配镜者处于动态环境下例如开车或者运动时佩戴。 Power in the progressive multifocal lens of the present invention not only meet the conventional progressive multifocal lens in the glasses when the wearer who is in a static environment that is reading the newspaper or a blackboard, etc., also meet the glasses are in motion, for example driving or Dynamic Environment when worn.
