Description

一种角膜接触镜 One kind of contact lenses

技术领域 FIELD

[0001] 本发明涉及一种眼镜,尤其涉及一种角膜接触镜。 [0001] The present invention relates to an ophthalmic lens, particularly to a contact lens.

背景技术 Background technique

[0002] 随着年龄增长,眼调节能力逐渐下降,从而引起患者看近距离物体时发生困难,以致在近距离工作中,必须在其屈光不正得以矫正之外另加凸透镜以补偿其丧失的调节能力,才能获得清晰的近视力,这种现象称为老视(presbyopia),俗称"老花眼"。 [0002] With age, decreased ability to regulate the eye, causing difficulty in the patient to see close objects, such that the close work, it is necessary to compensate for the loss of additional lens in addition to its refractive errors can be corrected regulation, in order to obtain a clear near vision, a phenomenon known as presbyopia (presbyopia), commonly known as "presbyopia."

[0003] 老视的实质是眼的调节能力减退。 [0003] Presbyopia is the essence of decreased ability to regulate the eye. 传统的矫治方法是佩戴正性框架镜片(即"老视镜"或"老花镜")。 The traditional treatment methods is wearing a positive lens frame (i.e., "old mirrors" or "reading glasses"). 其原理是使患者眼睛的焦点向近处移动。 The principle is the focus moved to the vicinity of the patient's eye. 佩戴该框架镜片后虽然近视力明显改善,但是由于只有一个焦点,所以佩戴后远视力会有明显下降。 After wearing the lens frame although significant improvement in near vision, but because there is only one focus, so far vision after wearing will be significantly decreased. 随着老龄化问题的日益加剧和生活质量的不断提高,这种传统的单焦点老视镜已经不能满足许多老视患者既希望看远清晰,又希望看近清晰的要求。 With the continuous improvement and increasing quality of life of aging, this traditional monofocal old mirrors have been unable to meet many patients with presbyopia clear both want to look too far, and hope to see nearly clear requirements. 因此,各种双焦点和多焦点老视框架镜和角膜接触镜(隐形眼镜)应运而生。 Thus, a variety of bifocal and multifocal contact lenses and presbyopia mirror frame (lens) came into being. 这些镜片虽然初步解决了既能看远又能看近的需求,但是也带来了各种视觉问题,如重影、眩晕、视物模糊、视物变形等等。 Although initially they solved these lenses to see both far and can demand to see near, but also brought a variety of vision problems such as double vision, dizziness, blurred vision, visual distortion and so on.

[0004] 在此,先介绍一下景深的概念,能同时被眼看清楚的空间深度称为眼的成像空间深度,即是眼的景深。 [0004] Here, to explain the concept of depth of field, can be simultaneously seeing clearly imaged spatial depth is called spatial depth of the eye, i.e., the depth of field of the eye.

[0005] 单焦点老视镜(凸透镜)只有一个焦点,相对于该焦点有一个景深。 [0005] Presbyopia monofocal lens (convex lens) is only one focus, a focal point with respect to the depth of field. 人们佩戴现有技术的单焦点老视镜后,可看清楚近距离的注视物,但由于现有技术的单焦点老视镜的景深较小,所以,远距离的注视物会落在景深之外,因此,人们佩戴现有技术的单焦点老视镜后,看不清楚远距离的注视物。 People wearing the prior art presbyopia monofocal lens, can see close attention was small but the prior art since the monofocal old mirrors depth of field, so that distant objects will fall depth of gaze in addition, therefore, the people wearing the prior art monofocal old mirrors, attention was not clear distance. 要想看清楚远距离的注视物必须摘掉单焦点老视镜。 To see distant gaze was a monofocal must remove the old mirrors. 这样十分不便。 This is very inconvenient. 特别是,当注视物的前后长度较长超过较小景深时,人们只能看清注视物的前部, 而看不清注视物的后部,或者,人们只能看清注视物的后部,而看不清注视物的前部。 In particular, when the longitudinal length thereof longer than the smaller gaze depth, one can only see the front fixation portion thereof, and can not see the rear fixation thereof, or, one can only see the rear portion thereof gaze , while the front was not clear gaze.

[0006] 双焦点老视镜(上半部为远焦镜,下半部为近焦镜)有两个焦点,相对于近焦点有一个近景深,相对于远焦点有一个远景深。 [0006] presbyopic bifocal lens (afocal lens upper half, the lower half is a close focus lens) has two foci, with respect to a near depth near focus relative to the far focus has a depth of vision. 人们佩戴现有技术的双焦点老视镜后,既可看清楚近距离的注视物,也可看清楚远距离的注视物。 People wearing the prior art bifocal presbyopia mirror, can look close attention was also see distance gaze thereof. 但由于近景深和远景深均较小,所以,近景深和远景深之间就出现了模糊区。 However, due to the near and far depth of depth of field are small, so the depth of field between near and far depth appeared fuzzy area. 位于模糊区的注视物人们就很难看清楚了。 Located fuzzy area was watching it is hard to see clearly.

[0007] 多焦点老视镜(从中部到边部焦点由近逐渐到远)有多个焦点,相对于每一个焦点都有一个景深。 [0007] Presbyopia multifocal lens (from the center to the edge gradually from near to far focus) focus a plurality of, with respect to each have a depth of focus. 人们佩戴现有技术的多焦点老视镜后,虽然可看清楚不同远近的注视物,但是,由于不同焦点的景深产生了重合,所以,人们看同一个注视物时有可能产生重影、眩晕、 视物变形的现象。 People wearing the prior art multifocal old mirrors, although the gaze see near and far objects, but, due to the different depth of focus is generated coincidence, therefore, it is possible to see when looking at the same object ghosting, vertigo , visual distortion phenomenon.

具体实施方式 Detailed ways

[0045] 如图1至图7所示,一种角膜接触镜,包括镜片1,所述镜片1包括透光区2和遮光区3,戴上角膜接触镜后,所述遮光区3遮住瞳孔4的一部分,所述透光区2罩住瞳孔4的另一部分。 [0045] As shown in FIGS. 1 to A 7 contact lens, comprising a lens 1, the lens 12 and the light shielding region comprises a light transmission area 3, after wearing the contact lens, the light-shielding area covering 3 the pupil portion 4, and the other portion of the light-transmitting covering the pupil region 2 to 4.

[0046] 成像原理说明如下。 [0046] The imaging principle described below.

[0047] 如图7所示,众所周知,人眼的结构犹如一台照相机。 [0047] As shown in FIG 7, it is known, the structure of the human eye like a camera. 角膜7、前后房8、瞳孔4、晶状体10和玻璃体11构成这台"照相机"的光学系统,医学称之为"屈光系统"。 7 cornea, the front and rear housing 8, 4 pupil, the lens 10 and the glass body 11 constituting this "camera" of the optical system, medicine called "refractive system." 其中,角膜7和晶状体10是该系统的"镜头"部分,而瞳孔4则是该系统的"光圈"部分。 Wherein, the cornea 10 and the lens 7 are "shot" of the system, the pupil is 4 "aperture" of the system. 屈光系统各部分的完美组合使进入眼内的光线形成一个清晰的物象。 Perfect combination of refractive system portion of light entering the eye forming a clear images. 视网膜12是这台"照相机"的感光系统;脉络膜和巩膜9则构成这台"照相机"的暗箱。 12 is a retinal this "camera" photosensitive system; choroid and sclera 9 constituting this black box "camera" in.

[0048] 如图8所示,根据光学的基本原理和照相机的应用实践可知,在焦点的前后,光线从聚集到扩散,点的影像从圆形光斑到光点(焦点),继而再扩散到圆形光斑。 [0048] As shown in FIG. 8, according to the basic principles of optics and camera application practice seen before and after the focus, the light gathered from the diffusion, the image points from the circular light spot point (focal point), and then re-diffuse into the circular spot. 这个焦点前面和后面的圆形光斑叫做弥散圆。 The circular spot is called the front and back focal circle of confusion. 由于人眼视网膜分辨力有限,当弥散圆直径小于人眼的分辨能力时,肉眼下依然视之为光点,此时人眼依然感觉影像是清晰的。 Because of the limited resolution of the human retina, when the dispersion diameter is less than the resolution capability of the human eye, the eye is still regarded as points of light, the human eye at this time still feel the image is clear. 这时,可以被肉眼视为一个点的最大弥散圆被称为容许弥散圆(Permissiblecircleofconfusion,8 )。 At this time, the naked eye can be considered as a maximum point of a circle of confusion is referred permissible circle of confusion (Permissiblecircleofconfusion, 8). 通常,容许弥散圆对应的人眼极限分辨角用e表示,正常人眼极限分辨角e为1'~2 '。 Typically, the allowable limit of the human eye to blur circle corresponding to the angle of resolution represented by e, the normal human eye resolution limit angle e is 1 'and 2'. 可见,在注视物(对焦点)的前后有一段范围,这个范围内景物上的点在视网膜上所成的像均在容许弥散圆的限定范围内,因此,均被肉眼视为清晰的像点。 Seen, there is a range was watching (point) before and after the point on the scene in this range into an image on the retina that are within the allowable range defined circle of confusion, therefore, it is considered a clear image visually point . 这段注视物(对焦点)前后的范围被称作景深(D印thoffield,A)。 This fixation thereof (point) is referred to as a range of acceptable depth (D printing thoffield, A). 此时,在焦点前后各有一个容许弥散圆,这两个容许弥散圆之间的距离被称作焦深。 At this time, each with a permissible circle before and after the focus, the distance between the two allowable circle of confusion is called depth of focus.

[0049] 景深公式如下所示。 As shown in [0049] the following equation depth.
