Abstract
Description
本發明是有關於一種光學鏡片，特別是指一種控制眼軸增長的光學鏡片。 The present invention relates to an optical lens, and more particularly to an optical lens that controls eye shaft growth.
近視是指人在看遠處時，平行光透過眼球屈光折射而匯聚在視網膜前，所以無法在視網膜上形成清晰的影像。近視可以透過凹透鏡來矯正，通常使用屈光度來衡量屈光異常的狀況。 Myopia means that when a person looks at a distance, the parallel light converges through the refractive power of the eye and converges in front of the retina, so it is impossible to form a clear image on the retina. Myopia can be corrected by a concave lens, and diopter is usually used to measure the condition of ametropia.
近視通常都肇因過度的閱讀及其它的近距離活動給眼睛帶來的過度的調節負擔，正常的人眼在從看遠處轉變為看近處時，物體在眼中所成的像將後移，從而不再落在視網膜上，而所看到的物體是模糊的。因此，為了重新看清楚物體，眼睛需要做出調節，即收縮睫狀肌，讓晶狀體變得更凸，從而形成更強的折射，讓物體的像重新回到視網膜上。然而，如果長期近距離用眼，睫狀肌的痙攣還可能刺激眼球前後軸的拉長，從而形成無法逆轉的近視。根據醫學資料研究，近視度數每增加100度(-1.00D)，眼軸長度就會增加0.37毫米，而眼軸越長，眼球後的視網膜所受的牽拉就越大，逐漸會造成視網膜出現退化現象，視網膜更大也可能會出現脫落，嚴重時更會造成視網膜剝離。 Myopia usually causes excessive adjustment burden on the eyes due to excessive reading and other close-range activities. When the normal human eye changes from looking far to looking close, the image formed by the object in the eye will move backward. So that it no longer falls on the retina, and the objects seen are blurred. Therefore, in order to see the object again, the eye needs to make adjustments, that is, shrink the ciliary muscles, make the lens more convex, and form a stronger refraction, so that the image of the object returns to the retina. However, if the eye is used for a long distance at a close distance, the ciliary muscle spasm may also stimulate the elongation of the anterior and posterior axes of the eyeball, thereby forming an irreversible myopia. According to medical data research, for every 100 degrees (-1.00D) increase in myopia, the length of the axial length will increase by 0.37 mm, and the longer the axial length, the greater the traction of the retina after the eyeball will gradually lead to retinal appearance. Degeneration, the retina is larger and may fall off, and in severe cases, it may cause retinal detachment.
因此，眼軸的長度若能調節不繼續增長，患者的近視度數較不會增加，故而控制近視患者於配戴眼鏡後能減緩眼軸增長而減緩近視加深。 Therefore, if the length of the eye axis can not be adjusted and the patient's myopia degree will not increase, the control of myopia patients can slow the growth of the eye axis and slow down the myopia after wearing the glasses.
如圖1，是顯示一近視患者的眼睛4未配戴近視鏡片時，遠方景物是成像於視網膜41前，圖2是該近視患者的眼睛4配戴一近視鏡片5時，遠方景物經由該近視鏡片5調節而成像於視網膜41上。其中，現有的近視鏡片5為球面凹透鏡，遠方景物經由該近視鏡片5靠近光軸的中心區域成像於視網膜41上，而遠方景物經由距離光軸較遠的周邊區域因球面像差的原因則是成像於視網膜41後方，因此眼睛4為了清楚地讓遠方景物成像於視網膜41上，則會做出調節，即收縮睫狀肌42，讓晶狀體43變得更凸，從而形成更強的折射，讓遠方景物經由近視鏡片5的周邊區成像能落在視網膜41上。但此時經由近視鏡片5中心區的成像則會移到視網膜41前形成模糊的視覺影像。如果眼睛4長期處於此種調節狀態，睫狀肌42的痙攣還可能刺激眼軸的拉長，從而造成近視的加深。 As shown in FIG. 1 , when the eye 4 of a myopic patient is not wearing the myopia lens, the distant scene is imaged before the retina 41 , and FIG. 2 is when the eye 4 of the myopia patient wears the myopia lens 5 , and the distant scene passes through the myopia . The lens 5 is adjusted to be imaged on the retina 41. Wherein, the existing myopia lens 5 is a spherical concave lens, and the distant scene is imaged on the retina 41 via the central region of the near vision lens 5 near the optical axis, and the distant scene is separated by the spherical aberration due to the peripheral region far from the optical axis. The image is imaged behind the retina 41, so that in order to clearly visualize the distant scene on the retina 41, the eye 4 adjusts to contract the ciliary muscle 42 to make the lens 43 more convex, thereby forming a stronger refraction. The distant scene can be imaged on the retina 41 by imaging the peripheral region of the myopic lens 5. However, at this time, the imaging through the central region of the myopic lens 5 moves to the front of the retina 41 to form a blurred visual image. If the eye 4 is in such a state of regulation for a long period of time, the sputum of the ciliary muscle 42 may also stimulate the elongation of the eye axis, thereby causing the deepening of myopia.
因此，本發明之目的，即在提供一種控制眼軸增長的光學鏡片。 Accordingly, it is an object of the present invention to provide an optical lens that controls axial growth.
於是，本發明之控制眼軸增長的光學鏡片，包含一中心區及一由該中心區朝外延伸的周邊區。該周邊區的屈光度小於中心區且朝外漸次遞減。 Thus, the optical lens of the present invention for controlling the growth of the axial axis comprises a central region and a peripheral region extending outward from the central region. The diopter of the peripheral zone is smaller than the central zone and gradually decreases outward.
較佳地，本發明之控制眼軸增長的光學鏡片，包含一中心區及一由該中心區朝外延伸的周邊區。該中心區具有相同的曲率及固定焦點，該周邊區由負球面像差漸變為正球面像差配置。 Preferably, the optical lens for controlling the growth of the axon of the present invention comprises a central region and a peripheral region extending outward from the central region. The central zone has the same curvature and a fixed focus, and the peripheral zone is gradually changed from a negative spherical aberration to a positive spherical aberration.
本發明之功效在於：當一近視患者配戴該光學鏡片時，遠方景物經由該光學鏡片的中心區成像於視網膜上，而遠方景物經由距離光軸較遠的周邊區且因該周邊區的屈光度是小於該中心區的屈光度而成像於視網膜上或前方，因此眼睛為了清楚地讓遠方景物成像於視網膜上，則會做出調節，即放鬆睫狀肌，讓晶狀體的曲率變大，從而讓遠方景物經由光學鏡片的周邊區的成像能落在視網膜上。以上眼睛調節方式可避免睫狀肌於一緊繃痙攣狀態而刺激眼軸的拉長，從而造成近視的加深。 The effect of the present invention is that when a myopic patient wears the optical lens, the distant scene is imaged on the retina via the central region of the optical lens, and the distant scene passes through the peripheral region farther from the optical axis and due to the diopter of the peripheral region It is smaller than the diopter of the central region and is imaged on the front or the front of the retina. Therefore, in order to clearly visualize the distant scene on the retina, the eye will make adjustments, that is, relax the ciliary muscle and enlarge the curvature of the lens, thereby allowing the distance to be far away. The imaging of the scene through the peripheral region of the optical lens can fall on the retina. The above eye adjustment method can prevent the ciliary muscle from stimulating the elongation of the eye axis in a tight state, thereby causing deepening of myopia.
有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之三個較佳實施例的詳細說明中，將可清楚的呈現。 The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of FIG.
在本發明被詳細描述之前，要注意的是，在以下的說明內容中，類似的元件是以相同的編號來表示。 Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖3，本發明控制眼軸增長的光學鏡片之第一較佳實施例，包含一中心區1、一位於周緣的盲區20及一由該中心區1朝外延伸且介於該中心區及該盲區20間的周邊區2。 Referring to FIG. 3, a first preferred embodiment of an optical lens for controlling axial growth of the present invention comprises a central zone 1, a blind zone 20 at the periphery, and a central region extending outwardly from the central zone 1 and The peripheral zone 2 of the blind zone 20.
該中心區1的兩相反側面具有固定的曲率而具有固定的焦點。 The opposite sides of the central zone 1 have a fixed curvature with a fixed focus.
該盲區20是非視覺區。 This dead zone 20 is a non-visual zone.
該周邊區2其屈光度小於該中心區1的屈光度並朝外漸次遞減，較佳地，該周邊區2的屈光度與該中心區1的 屈光度的差由鄰近該中心區1處朝外依序由+0.25D遞增至+3.00D。 The peripheral region 2 has a diopter smaller than the diopter of the central region 1 and gradually decreases outward, preferably, the diopter of the peripheral region 2 and the central region 1 The difference in diopter is sequentially increased from +0.25D to +3.00D in the vicinity of the central region 1.
較佳地，該周邊區2的兩相反側面所形成的球面像差由鄰近該中心區1處往外是由負球面像差逐漸變為正球面像差。 Preferably, the spherical aberration formed by the opposite sides of the peripheral region 2 gradually changes from a negative spherical aberration to a positive spherical aberration from adjacent to the central region 1.
參閱圖4，當一近視患者的眼睛4配戴該光學鏡片且在注視遠方時，遠方景物經由該光學鏡片的中心區1成像於視網膜的黃斑中心凹(fovea)上，而遠方景物經由距離光軸較遠的周邊區2且因該周邊區2的屈光度是小於該中心區1的屈光度而成像於視網膜41前方，因此該眼睛4為了清楚地讓遠方景物成像於視網膜41上，則會做出調節，即放鬆睫狀肌42，讓晶狀體43的曲率變大，從而形成更弱的折射，讓遠方景物經由光學鏡片的周邊區2的成像能落在視網膜41上。以上該眼睛4的調節方式可避免睫狀肌42於一緊繃痙攣狀態而刺激眼軸的拉長，從而造成近視的加深。 Referring to FIG. 4, when the eye 4 of a myopic patient wears the optical lens and is looking far away, the distant scene is imaged on the fovea of the retina via the central region 1 of the optical lens, and the distant scene passes the distance light. The peripheral region 2 farther from the axis and because the diopter of the peripheral region 2 is smaller than the diopter of the central region 1 is imaged in front of the retina 41, so the eye 4 is made to clearly image the distant scene on the retina 41. Adjustment, i.e., relaxation of the ciliary muscle 42, causes the curvature of the lens 43 to become larger, thereby forming a weaker refraction, allowing the distant scene to fall onto the retina 41 via imaging of the peripheral region 2 of the optical lens. The above adjustment of the eye 4 can prevent the ciliary muscle 42 from stimulating the elongation of the eye axis in a tight state, thereby causing deepening of myopia.
參閱圖5，本發明控制眼軸增長的光學鏡片之第二較佳實施例，為一隱形眼鏡(contact lens)，包含一中心區1、一盲區20及一由該中心區1朝外延伸且介於該中心區1及該盲區20間的周邊區2。本實施例中，該中心區1為以該光學鏡片的視覺中心為原點且直徑為3.0mm所構成的圓形區域。該中心區1的兩相反側面具有固定的曲率而具有固定的焦點。 Referring to FIG. 5, a second preferred embodiment of the optical lens for controlling axial growth of the present invention is a contact lens comprising a central region 1, a blind zone 20 and an outer region extending outward from the central region 1 and A peripheral zone 2 between the central zone 1 and the blind zone 20. In the present embodiment, the central area 1 is a circular area composed of a visual center of the optical lens and having a diameter of 3.0 mm. The opposite sides of the central zone 1 have a fixed curvature with a fixed focus.
該盲區20是非視覺區。 This dead zone 20 is a non-visual zone.
該周邊區2外緣為以該光學鏡片的視覺中心為原點且 直徑為6.0mm所構成的同心圓外圍。該周邊區2其屈光度小於該中心區1的屈光度且朝外漸次遞減。較佳地，該中心區1的屈光度為-3.00D，該周邊區2的屈光度由鄰近該中心區1處朝外依序由-2.00D遞減至+0.00D。較佳地，該周邊區2的兩相反側面所形成的球面像差由鄰近該中心區1處往外是由負球面像差逐漸變為正球面像差。 The outer edge of the peripheral region 2 is originated from the visual center of the optical lens The periphery of the concentric circle formed by a diameter of 6.0 mm. The peripheral zone 2 has a diopter that is less than the diopter of the central zone 1 and gradually decreases outward. Preferably, the central region 1 has a diopter of -3.00D, and the diopter of the peripheral region 2 is sequentially decreased from -2.00D to +0.00D in the vicinity of the central region 1. Preferably, the spherical aberration formed by the opposite sides of the peripheral region 2 gradually changes from a negative spherical aberration to a positive spherical aberration from adjacent to the central region 1.
其中，該光學鏡片為由甲基丙烯酸-2-羥基乙酯(HydroxyEthylMethAcrylate,HEMA)及甲基丙烯酸(MethAcrylic Acid,MAA)反應而成的共聚合物(copolymer)所製成。該光學鏡片由一乾燥狀態轉變成一濕潤狀態，其徑向澎潤率為1.28。該光學鏡片的中心厚度為0.08mm。該光學鏡片於該濕潤狀態的含水量為55%。該光學鏡片在35℃時的透氧量為22*10-11[cm3O2(STP)*cm]/(sec*cm2*mmHg)。 The optical lens is made of a copolymer obtained by reacting Hydroxy Ethyl Meth Acrylate (HEMA) and Meth Acrylic Acid (MAA). The optical lens was transformed from a dry state to a wet state with a radial wetting ratio of 1.28. The optical lens has a center thickness of 0.08 mm. The optical lens had a water content of 55% in the wet state. The optical lens had an oxygen permeability of 35*10 -11 [cm 3 O 2 (STP)*cm]/(sec*cm 2 *mmHg) at 35 °C.
參閱圖6，當一近視患者的眼睛4配戴該光學鏡片時，遠方景物經由該光學鏡片的中心區1成像於視網膜41的黃斑中心凹上，而遠方景物經由距離光軸較遠的周邊區2且因該周邊區2的屈光度是小於該中心區1的屈光度而成像於視網膜41前方，因此該眼睛4為了清楚地讓遠方景物成像於視網膜41上，則會做出調節，即放鬆睫狀肌42，讓晶狀體43的曲率變大，從而形成更弱的折射，讓遠方景物經由光學鏡片的周邊區2的成像能落在視網膜41上。以上該眼睛4的調節方式可避免睫狀肌42的於一緊繃痙攣狀態而刺激眼軸的拉長，從而造成近視的加深。 Referring to FIG. 6, when the eye 4 of a myopic patient wears the optical lens, the distant scene is imaged on the fovea of the retina 41 via the central region 1 of the optical lens, and the distant scene passes through the peripheral region farther from the optical axis. 2 and because the diopter of the peripheral zone 2 is smaller than the diopter of the central zone 1 and is imaged in front of the retina 41, the eye 4 is adjusted to visualize the distant scene on the retina 41, that is, to relax the ciliary shape. The muscle 42 causes the curvature of the lens 43 to become larger, thereby forming a weaker refraction, allowing the distant scene to fall on the retina 41 via the imaging of the peripheral region 2 of the optical lens. The adjustment of the eye 4 above avoids the tensioning of the ciliary muscle 42 in a tight state, thereby stimulating the elongation of the eye axis, thereby causing deepening of myopia.
參閱圖7與圖8，本發明控制眼軸增長的光學鏡片之第 三較佳實施例，為一框架眼鏡的光學鏡片且為聚碳酸酯樹脂(Polycarbonate,PC)所製成，聚碳酸酯樹脂折射率為1.586，該光學鏡片包含一中心區1、一盲區20及一由該中心區1朝外延伸且介於該中心區1及該盲區20間的周邊區2。 Referring to FIG. 7 and FIG. 8, the optical lens of the present invention for controlling the growth of the axial axis The third preferred embodiment is an optical lens of a frame glasses and is made of polycarbonate resin (PC). The polycarbonate resin has a refractive index of 1.586, and the optical lens comprises a central zone 1 and a blind zone 20 and A peripheral zone 2 extending outwardly from the central zone 1 and between the central zone 1 and the blind zone 20.
該中心區1為以視覺中心為原點，且短軸直徑為2.0±1.0公分及長軸直徑為2.5±1.0公分所構成的區域，本實施例是採短軸直徑2.0公分及長軸直徑2.5公分。 The central area 1 is an area composed of a visual center as an origin, and a short axis diameter of 2.0±1.0 cm and a major axis diameter of 2.5±1.0 cm. In this embodiment, the short axis diameter is 2.0 cm and the long axis diameter is 2.5. Centimeters.
該盲區20是非視覺區。 This dead zone 20 is a non-visual zone.
該周邊區2及該盲區20遠離眼睛的一側以聚合或附著的方式形成一由聚甲基丙烯酸甲脂(PolyMethylMethAcrylate,PMMA)材料所構成的附著層3。聚甲基丙烯酸甲脂的折射率為1.49。該附著層3的厚度由鄰近該中心區1處往外至靠近該光學鏡片邊緣處的變化為由1μm逐漸增加至300μm。較佳地，該附著層3的厚度由鄰近該中心區1處往外至遠離該中心區1外緣0.5cm處的變化為由5μm逐漸增加至200μm，且該附著層遠離該中心區外緣0.5cm外的區域厚度則為200μm。 The peripheral zone 2 and the side of the blind zone 20 away from the eye form an adhesion layer 3 composed of polyMethyl Meth Acrylate (PMMA) material in a polymeric or adhesive manner. Polymethyl methacrylate has a refractive index of 1.49. The thickness of the adhesion layer 3 is gradually increased from 1 μm to 300 μm from the vicinity of the central region 1 to the edge of the optical lens. Preferably, the thickness of the adhesion layer 3 is gradually increased from 5 μm to 200 μm from the center of the central region 1 to 0.5 cm away from the outer edge of the central region 1, and the adhesion layer is away from the outer edge of the central region by 0.5. The thickness outside the cm is 200 μm.
更佳地，該附著層3以複合材料所構成，其折射率離該中心區1的中心越遠則越小。 More preferably, the adhesion layer 3 is composed of a composite material whose refractive index is smaller as it is farther from the center of the central region 1.
參閱圖9，當一近視患者的眼睛4配戴該光學鏡片時，遠方景物經由該光學鏡片的中心區1成像於視網膜41的黃斑中心凹上，因該周邊區2為複合式材料其折射率小於該中心區的折射率，而使得其屈光度是小於該中心區的屈光度，因此遠方景物經由該光學鏡片的周邊區2而成像於視 網膜41前方，因此該眼睛4為了清楚地讓遠方景物成像於視網膜41上，則會做出調節，即放鬆睫狀肌42，讓晶狀體43的曲率變大，從而形成更弱的折射，讓遠方景物經由光學鏡片的周邊區2的成像能落在視網膜41上。以上該眼睛的調節方式可避免睫狀肌42的於一緊繃痙攣狀態而刺激眼軸的拉長，從而造成近視的加深。 Referring to FIG. 9, when the eye 4 of a myopic patient wears the optical lens, the distant scene is imaged on the fovea of the retina 41 via the central region 1 of the optical lens, since the peripheral region 2 is a refractive index of the composite material. Less than the refractive index of the central region such that its diopter is less than the diopter of the central region, so that the distant scene is imaged through the peripheral region 2 of the optical lens The front of the omentum 41, so that the eye 4 in order to clearly image the distant scene on the retina 41, will make adjustment, that is, relax the ciliary muscle 42, so that the curvature of the lens 43 becomes larger, thereby forming a weaker refraction, so that the distance The image can fall on the retina 41 via imaging of the peripheral region 2 of the optical lens. The above adjustment of the eye can avoid the tension of the ciliary muscle 42 in a tight state, thereby stimulating the elongation of the eye axis, thereby causing the deepening of myopia.
綜合上述，本發明之控制眼軸增長的光學鏡片，藉由光學鏡片的中心區1及周邊區2具有不同的屈光度，使得遠方景物經由該光學鏡片的中心區1成像於視網膜41的黃斑中心凹上，而遠方景物經由距離光軸較遠的周邊區2且因該周邊區2的屈光度是小於該中心區1的屈光度而成像於視網膜41前方。因此該眼睛4為了清楚地讓遠方景物成像於視網膜41上，則會做出調節，即放鬆睫狀肌42，讓晶狀體43的曲率變大，從而形成更弱的折射，讓遠方景物經由光學鏡片的周邊區2的成像能落在視網膜41上。以上該眼睛4的調節方式可避免睫狀肌42的於一緊繃痙攣狀態而刺激眼軸的拉長，從而造成近視的加深，故確實能達成本發明之目的。 In summary, the optical lens for controlling the growth of the axial axis of the present invention has different diopters by the central region 1 and the peripheral region 2 of the optical lens, so that the distant scene is imaged on the fovea of the retina 41 via the central region 1 of the optical lens. Above, the distant scene is imaged in front of the retina 41 via the peripheral region 2 farther from the optical axis and because the diopter of the peripheral region 2 is smaller than the diopter of the central region 1. Therefore, in order to clearly visualize the distant scene on the retina 41, the eye 4 adjusts to relax the ciliary muscle 42 to make the curvature of the lens 43 larger, thereby forming a weaker refraction, allowing the distant scene to pass through the optical lens. The imaging of the peripheral region 2 can fall on the retina 41. The adjustment of the eye 4 above avoids the tension of the ciliary muscle 42 in a tight state, thereby stimulating the elongation of the eye axis, thereby causing the deepening of myopia, so that the object of the present invention can be achieved.
