Description
본 발명은 눈의 망막 세포의 시감도(視感度) 곡선을 이용함으로써 물체를 보다 선명하게 볼 수 있는 시력 보정용 안경렌즈에 관한 것이다.TECHNICAL FIELD The present invention relates to a spectacle correcting spectacle lens capable of viewing an object more clearly by using a visibility curve of retinal cells of an eye.
일반적으로 눈에 유해한 자외선 및 전자파를 차단할 목적으로 안경렌즈 표면에 자외선 차단막 및 전자파 차단막을 접착하고 있다. 따라서 이러한 안경렌즈로 눈에 유해한 자외선 및 전자파를 어느 정도 차단할 수 있어 시력을 보호할 수 있는 장점을 가지는 것이 사실이다.In general, a UV blocking film and an electromagnetic wave blocking film are adhered to the spectacle lens surface in order to block harmful UV rays and electromagnetic waves. Therefore, it is true that such spectacle lenses can block ultraviolet rays and electromagnetic waves harmful to the eyes to some extent and protect the eyesight.
또한, 최근에는 시력을 보호하는 것에 국한하지 아니하고 원시, 근시, 난시 등의 시력을 교정하여 줌으로써 시력을 회복시켜 주는 시력 교정용안경알이 개발되고 있다.In recent years, eyeglasses for correcting vision have been developed, which are not limited to protecting eyesight, but recovering eyesight by correcting vision such as hyperopia, myopia and astigmatism.
이러한 시력 교정용 안경알은 볼록한 판형 곡면에 0.7mm 내지 0.9mm 크기의 다수개의 핀홀(pin hole)들을 천공하고, 볼록한 판형 곡면의 표면에는 청색, 녹색 등의 색상을 착색하고 있다. 이러한 안경알은 바늘구멍(pin hole)들을 뚫었다하여 마이크로홀 안경 또는 핀홀 안경이라고 한다. 마이크로홀 안경은 핀홀을 통해 근시, 원시, 난시, 노시 등 굴절 이상인 사람이 핀홀효과를 이용하여 먼 곳(근시)이나 가까운 물체(노안)를 볼 수 있다.The eyeglasses for correcting eyesight puncture a plurality of pin holes having a size of 0.7 mm to 0.9 mm on the convex plate curved surface, and colors blue, green, etc. on the surface of the convex plate curved surface. Such eyeglasses are called microhole glasses or pinhole glasses because they penetrate the pin holes. Through pinholes, microhole glasses allow people with refractive errors such as myopia, hyperopia, astigmatism, and presbyopia to see distant (myopia) or near objects (presbyopia) using the pinhole effect.
하지만, 이러한 마이크로홀 안경은 여전히 렌즈의 굴절력에 의한 시력교정을 하지 못하기 때문에 충분한 시력의 향상을 가져올 수 없고, 핀홀 부분 외의 부분은광선이 투과하지 못하기 때문에 눈이 이용할 수 있는 광량이 제한 되어져 상의 밝기가 떨어지는 문제점이 있다.However, these micro-hole glasses still cannot achieve sufficient vision improvement due to the inability to correct the vision due to the refractive power of the lens, and the amount of light available to the eyes is limited because the light outside the pinhole portion is not transmitted. There is a problem that the brightness of the image falls.
한편, 상기한 마이크로홀 안경의 기술적 배경을 설명하면 다음과 같다.Meanwhile, the technical background of the microhole glasses will be described below.
빛을 받아들이는 광폭량(광선량)은 눈의 동공(조리개)의 크기와 관련이 있다. 동공의 직경은 대개 2 - 6mm이다. 도 2a에서는 동공이 지나치게 큰 경우에 입사되는 경우이다. 이 때는 광폭량이 너무 많아서 망막쪽에 수차(收差)가 발생되어 망막에 결상되는 상(像)이 흐리게 나타난다.The amount of light that receives light is related to the size of the pupil (aperture) of the eye. The diameter of the pupil is usually 2-6 mm. In FIG. 2A, the case is incident when the pupil is too large. At this time, the amount of light is so large that aberration occurs in the retina, and the image formed on the retina appears blurry.
반면에, 도 2b에서는 핀홀을 통하여 입사되는 경우이다. 이 때는 입사빔의 광축 주변빔의 핀홀에 의한 차단효과로 수차발생이 적은 광축상의 영역을 지나는 광선에 의해서만 결상되어진 상(像)으로 상의 흐린 정도가 현저하게 감소된다.On the other hand, in FIG. 2B, the case is incident through the pinhole. At this time, the blurring degree of the image to the image formed only by the light rays passing through the region on the optical axis with less aberration is reduced due to the pinhole of the beam around the optical axis of the incident beam.
상기한 핀홀에 의해 입사되는 광량폭을 인위적으로 제한하여 먼 곳(근시)이나 가까운 물체(노안)를 볼 수 있도록 한 것이 마이크로홀 안경의 원리이다.The principle of microhole glasses is to artificially limit the amount of light incident by the pinholes so that a distant (myopia) or near object (presbyopia) can be seen.
이에 본 발명의 목적은 눈의 망막세포의 시감도 곡선을 이용하여 안경렌즈의 공간상 파장별 투과율을 다르게 함으로써, 시력보정에 탁월한 효과를 주는 시력보정용 안경렌즈를 제공하는데 있다.Accordingly, an object of the present invention is to provide a spectacle correcting spectacle lens having an excellent effect on vision correction by varying the transmittance for each wavelength in the spectacle lens using the visibility curve of the retinal cells of the eye.

Terms to be described later are set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer producing the product, and the definitions should be made based on the contents throughout the present specification.
상기한 기술적 과제를 달성하기 위한 본 발명의 시력 보정용 안경렌즈는 렌즈부와, 상기 렌즈부의 표면에 접착되는 박막을 포함하여 구성되는 안경렌즈에 있어서, 상기 박막은 스펙트럼상 특정영역의 빛을 차단하는 차단영역과, 직경의 크기가 3mm - 0.01mm 이내로 되고 다수개의 핀홀 형태로 만들어지는 입사영역으로 형성하는 것을 특징으로 한다.The spectacle lens for vision correction according to the present invention for achieving the above technical problem comprises a lens portion and a thin film adhered to the surface of the lens portion, the thin film is to block the light of a specific region in the spectrum It is characterized in that the blocking area, and the size of the diameter is within 3mm-0.01mm and formed into an incident area made of a plurality of pinholes.
이하, 첨부도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
도 3a는 본 발명에 따른 시력 보정용 안경렌즈의 예시도이고, 도 3b는 도 3a의 일부 확대 단면도이며, 도 4는 본 발명에 따른 다른 시력 보정용 안경렌즈의 예시도이며, 도 5는 본 발명에 따른 또 다른 시력 보정용 안경렌즈의 예시도이다.3A is an exemplary view of an eyeglass correcting lens according to the present invention, FIG. 3B is a partially enlarged cross-sectional view of FIG. 3A, FIG. 4 is an exemplary view of another eyeglass correcting lens according to the present invention, and FIG. Another example of the spectacle lens for correcting vision according to.
본 발명의 시력 보정용 안경렌즈는 크게 렌즈부(10)와 박막(20)을 포함하여 구성된다.The spectacle lens for vision correction according to the present invention includes a lens unit 10 and a thin film 20.
렌즈부(10)는 안경렌즈에 해당되는 것이며, 종래의 마이크로홀 안경알과 다르다. 종래의 마이크로홀 안경알은 볼록한 판형 곡면의 표면에 핀홀을 천공하는 것이지만, 본 발명의 렌즈부(10)에는 핀홀을 전혀 형성하지 않은 것이다. 즉, 본 발명의 렌즈부(10)는 일반적으로 쓰고 있는 근시, 원시, 난시 등의 오목 내지 볼록 렌즈와 다름 없는 것이다.The lens unit 10 corresponds to the spectacle lens and is different from the conventional microhole eyeglasses. Conventional micro-hole eyeglasses puncture a pinhole on the surface of a convex plate curved surface, but do not form any pinhole in the lens portion 10 of the present invention. In other words, the lens unit 10 of the present invention is similar to concave or convex lenses such as myopia, hyperopia, astigmatism, and the like, which are generally used.
사람의 눈은 노란색 빛의 파장에 의해 시감도가 가장 예민하게 반응하고 있다. 즉, 외부의 물체를 눈으로 볼 때 노란색의 파장으로 물체의 윤곽을 인식하며, 다른 파장의 빛으로는 물체의 색감을 인식하는 것으로 알려져 있다. 이를 시감도 곡선으로 나타내면 도 1과 같다. 즉, 도 1에서는 빛의 파장이 노란색일때 시감도가 가장 높은 것으로 나타내고 있다. 따라서 사람이 외부의 물체를 볼 때 노란색 빛의 파장으로 물체의 윤곽을 인식하는 것을 알 수 있다.Human eyes are most sensitive to visibility by the wavelength of yellow light. That is, it is known that the outline of the object is recognized by the yellow wavelength when the external object is seen by the eye, and the color of the object is recognized by the light of the other wavelength. This is shown in FIG. 1 as a visibility curve. That is, in FIG. 1, visibility is the highest when the wavelength of light is yellow. Therefore, when a person looks at an external object, it can be seen that the contour of the object is recognized by the wavelength of yellow light.
따라서 물체의 윤곽선을 인식하는 노란색 계통의 빛에 상기에서 언급한 핀홀효과(도2b 참조)를 주어서 보다 선명한 물체의 윤곽을 인식할 수 있도록 함이 본 발명의 핵심이라고 할 수 있다.Therefore, it is the core of the present invention to give the above-mentioned pinhole effect (see FIG. 2B) to the light of the yellow system that recognizes the outline of the object so that the outline of the object can be recognized more clearly.
박막(20)은 노란색 계통의 빛을 차단할 수 있도록 특정한 재질로 코팅 내지 착색 처리된 차단영역(21)과, 직경의 크기가 약 3mm - 0.01mm 이내로 되고 다수개의 핀홀 형태로 만들어지는 입사영역(22)으로 구분되어 구성된다.The thin film 20 has a blocking region 21 coated or colored with a specific material to block light of a yellow system, and an incident region 22 having a diameter of less than about 3 mm to 0.01 mm and made of a plurality of pinholes. It is divided into).
여기서, 차단영역(21)은 노란색 계통의 빛만을 차단하는 부분으로 코팅 내지 착색처리 하게 된다. 그 재질로는 불화세리움(CeF3), 이산화지르코늄(ZrO2), 불화마그네슘(MgF2) 등의 재료로 적층하여 형성할 수 있다. 이 같이 형성된 차단영역(21)은 노란색 계통의 빛은 차단하지만 다른 빛의 파장은 투과시킨다.Here, the blocking area 21 is a coating or coloring process to block only the light of the yellow system. The material can be formed by laminating with materials such as cerium fluoride (CeF 3 ), zirconium dioxide (ZrO 2 ), magnesium fluoride (MgF 2 ), or the like. The blocking region 21 formed as described above blocks yellow light but transmits other light wavelengths.
입사영역(22)은 모든 빛은 물론이거니와 특히, 노란색 빛을 입사하는 부분으로서 렌즈부(10)에 코팅 처리를 하지 않고 다수개의 핀홀 형태로 이루어진다. 이는 종래의 마이크로홀 안경에서 형성되는 핀홀과는 다른 개념이지만, 본 명세서에서편의상 핀홀이라 칭한다. 입사영역(22)의 각 핀홀의 직경은 약 3mm에서 0.01mm 이내로 제한하는 것은 눈의 동공(조리개:외부의 빛을 받아들이는 부분)의 크기가 약 2 - 6mm 정도이므로 입사영역(22)의 각 핀홀의 최대 직경이 약 3mm 이내로 제한함으로써 노란색 빛의 입사 광폭량을 동공(조리개)의 직경보다 작게 하여 수차발생을 줄일 수 있다.The incident area 22 is formed of a plurality of pinholes, as well as all the light, and particularly, a part of incident yellow light, without coating the lens 10. This is a different concept from the pinhole formed in the conventional microhole glasses, but is referred to herein as a pinhole for convenience. The diameter of each pinhole in the incident region 22 is limited to within about 3 mm to 0.01 mm, since the size of the pupil of the eye (aperture: the part that receives external light) is about 2-6 mm, so that the angle of the incident region 22 By limiting the maximum diameter of the pinhole to within about 3mm, the aberration generation can be reduced by making the incident light width of yellow light smaller than the diameter of the pupil (aperture).
상기와 같이 형성되는 본 발명의 안경렌즈는 차단영역(21)에서는 노란색 빛을 차단하고, 입사영역(22)을 통해서만 노란색 빛을 제한적으로 입사하게 됨으로써, 눈의 망막에 결상되는 상(像)의 선명도를 높일 수 있다.The spectacle lens of the present invention formed as described above blocks the yellow light in the blocking area 21 and restricts incident yellow light only through the incident area 22, thereby forming an image formed on the retina of the eye. You can increase the sharpness.
도 6a, 6b에서는 본 발명에 따른 안경렌즈의 스펙트럼 분포를 보여주는 그래프로서, 도 6a는 차단영역(21)의 투과곡선 그래프로, 이 때는 모든 빛이 투과(입사)되지만 노란색 빛은 거의 차단되는 것을 보여준다. 도 6b는 입사영역(22)의 투과곡선 그래프로, 다른 모든 색깔의 빛과 함께 노란색 빛이 모두 투과(입사)되는 것을 보여준다.6A and 6B are graphs showing the spectral distribution of the spectacle lens according to the present invention, and FIG. 6A is a transmission curve graph of the blocking region 21. In this case, all light is transmitted (incident) but yellow light is almost blocked. Shows. FIG. 6B is a graph of the transmission curve of the incident region 22, showing that all yellow light is transmitted (incident) together with all other colors of light.
한편, 본 발명의 입사영역(22)을 이루는 핀홀의 각 형태는 도 3a 및 도 3b에서와 같이, 사각형으로 형성될 수도 있고, 도 4에서와 같이, 원형으로 형성될 수도 있으며, 도 5에서와 같이, 핀홀과 핀홀 사이는 연결라인(23)으로 연결될 수도 있다.On the other hand, each shape of the pinhole constituting the incident region 22 of the present invention may be formed in a square, as shown in Figure 3a and 3b, may be formed in a circular shape, as shown in Figure 4, Likewise, the pinhole and the pinhole may be connected to the connection line 23.
상기한 박막(20)을 렌즈부(10)에 형성하는 방법은 코팅 처리할 수 있으며, 또는 도 7에서와 같이 접착식 필름 형태로 만들어서 기존의 안경 렌즈부(10)에 직접 접착할 수도 있다.The method of forming the thin film 20 on the lens unit 10 may be coated, or may be directly bonded to the existing spectacle lens unit 10 by making an adhesive film as shown in FIG. 7.
이상에서와 같이, 본 발명의 시력 보정용 안경렌즈는 표면에 시감도 곡선의 감도가 예민한 영역의 파장의 빛에 대해서는 핀홀효과를 유발시켜 외부 물체의 선명도를 증가시켜 주고, 그 외의 파장의 빛에 대해서는 선택적으로 투과시켜서 색감을 가지게 해 줌으로서 종래의 안경렌즈에 비해서 시력 개선 효과가 보다 탁월한 효과를 갖는다.As described above, the spectacle lens for correcting vision of the present invention causes a pinhole effect to light of a wavelength having a sensitive sensitivity curve on the surface to increase the sharpness of an external object, and is selective to light of other wavelengths. As a result, the visual acuity improvement effect is more excellent than that of the conventional spectacle lens by allowing the color to pass through the color.
