Description
본발명은 색체변화 기능을 가진 광변색 컬러 콘택트렌즈 및 이의 제조방법에 관한 것으로, 보다 상세하게는 콘택트렌즈 패턴에 변색 안료를 도입시키되, 색상을 선명하게 발현시키기 위해 렌즈 컬러 패턴 및 색상에 따라 그에 맞는 변색을 발현 시켜 렌즈의 심미감을 높이고 다채로움과 다양성을 소비자에게 제공하는 색체변화 기능을 가진 광변색 컬러 콘택트렌즈 및 이의 제조방법에 관한 것이다.The present invention relates to a photochromic color contact lens having a color-changing function and a method for manufacturing the same, and more specifically, to a photochromic color contact lens having a color-changing function and a method for manufacturing the same, which introduces a color-changing pigment into a contact lens pattern and, in order to express the color clearly, expresses color change appropriate to the lens color pattern and color, thereby enhancing the aesthetics of the lens and providing variety and diversity to the consumer.
일반적으로 콘택트렌즈 시장은 안경테/렌즈 산업보다는 작은 규모이나 시력 교정 목적뿐만 아니라 홍채 컬러 패턴 디자인에 따른 미용 기능의 수요가 늘어나 매년 콘택트렌즈 착용자는 증가하고 있으며 이에 따라 콘택트렌즈 시장 규모는 증가하는 추세이다.In general, the contact lens market is smaller than the eyeglass frame/lens industry, but the number of contact lens wearers is increasing every year due to the increasing demand for cosmetic functions according to iris color pattern design in addition to vision correction purposes, and accordingly, the size of the contact lens market is on the rise.
이미 태양광에 의한 안구를 보호하기 위한 목적으로 선글라스, 고글 등이 사용되고 있으나, 태양광의 방향에 따라 빛을 차단하지 못하거나, 광량에 따라 투과도가 제어되지 못해 시야가 제한된다는 단점이 있음 또한, 실내외 이동 시 매번 탈착해야하는 번거로움이 존재함. 이를 개선하기 위한 변색렌즈가 개발되어 왔다.Sunglasses, goggles, etc. are already being used to protect the eyes from sunlight, but they have the disadvantage of not being able to block light depending on the direction of the sunlight, or of not being able to control the transmittance depending on the amount of light, which limits the field of vision. In addition, there is the inconvenience of having to take them off every time you move indoors or outdoors. To improve this, photochromic lenses have been developed.
또한 변색렌즈의 경우 클리어 렌즈에만 적용되어 왔고, 콘택트렌즈의 미용적인 디자인을 선호하는 고객들의 니즈를 충족시키기엔 아쉬움이 있다.In addition, in the case of photochromic lenses, they have only been applied to clear lenses, and it is regrettable that they do not meet the needs of customers who prefer the cosmetic design of contact lenses.

그러나 상기 종래기술들은 콘택트 렌즈 패턴에 변색 안료를 도입시키되, 색상을 선명하게 발현시키기가 어렵고 렌즈 컬러 패턴 및 색상에 따라 그에 맞는 적절한 변색을 발현 시켜 렌즈의 심미감을 제공하지 못하여 다채로움과 다양성을 소비자에게 제공할 수 없는 단점이 있었다.However, the above conventional technologies have the disadvantage that they introduce discoloration pigments into contact lens patterns, but it is difficult to express colors clearly, and they cannot provide the aesthetics of lenses by expressing appropriate discoloration according to the lens color pattern and color, so they cannot provide variety and diversity to consumers.
따라서 본발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 콘택트 렌즈 패턴에 변색 안료를 도입시키되, 색상을 선명하게 발현시키기 위해 렌즈 컬러 패턴 및 색상에 따라 그에 맞는 변색을 발현 시켜 렌즈의 심미감을 높이고 다채로움과 다양성을 소비자에게 제공하는 색체변화 기능을 가진 광변색 컬러 콘택트렌즈 및 이의 제조방법을 제공하고자 하는 것이다.Accordingly, the present invention has been made to solve the above problems, and provides a photochromic color contact lens having a color-changing function, which introduces a discoloration pigment into a contact lens pattern, but expresses discoloration appropriate to the lens color pattern and color in order to express the color clearly, thereby enhancing the aesthetics of the lens and providing variety and diversity to the consumer, and a method for manufacturing the same.
또한, 변색기능뿐만 아니라 다양한 제품의 패턴과 결합시켜 차별화된 렌즈를 제공하며, 또한 렌즈에 변색안료가 발현되어 또 다른 색상이 연출되고, 독특한 문양 발현 등 개성있고, 독특한 렌즈에도 적용시킬 수 있어 현재 나오고 있는 제품보다 다채롭고 차별화된 컬러 콘택트렌즈를 제공하고자 하는 것이다.In addition, it is possible to provide differentiated lenses by combining them with various product patterns in addition to the discoloration function, and also to apply it to unique and individual lenses such as the expression of discoloration pigments in the lenses to produce another color and the expression of unique patterns, thereby providing more diverse and differentiated color contact lenses than the products currently on the market.
이에 빛의 광량에 따라 홍채조절의 기능성과 색체가 변화하는 시각적인 패턴을 추가하여 경쟁력을 가진 렌즈를 제공하고자 하는 것이다.Accordingly, the goal is to provide a competitive lens by adding the functionality of iris adjustment and a visual pattern that changes color depending on the amount of light.

본발명은 색체변화 기능을 가진 광변색 컬러 제조방법에 관한 것으로, 콘택트렌즈의 1차 변색 안료층위에 2차 변색 안료층을 형성하는 것을 특징으로 한다.The present invention relates to a method for manufacturing a photochromic color having a color-changing function, characterized by forming a secondary discoloration pigment layer on a primary discoloration pigment layer of a contact lens.
또한, 1차 시안 변색 안료 양은 30~70중량%, 2차 시안 변색 안료 양: 30~70중량%인 것을 특징으로 한다.In addition, it is characterized in that the amount of the primary cyanochromic pigment is 30 to 70 wt%, and the amount of the secondary cyanochromic pigment is 30 to 70 wt%.
그리고 본발명은 상기의 제조방법에 의해 제조되는 색체변화 기능을 가진 광변색 컬러 콘택트렌즈인 것을 특징으로 한다.And the present invention is characterized by a photochromic color contact lens having a color-changing function manufactured by the above-mentioned manufacturing method.
본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention is described in detail with reference to the attached drawings as follows.
본발명은 렌즈 변색을 패턴화 하여 적용한 것으로 동공조절 렌즈이기도 한다. 그러므로 눈부심 방지를 위한 홍채조절 제품에도 적용된다.The present invention is a pupil-adjusting lens that applies lens discoloration in a patterned manner. Therefore, it is also applicable to iris-adjusting products for preventing glare.
도 1은 본발명의 1차변색패턴 광학부(5mm) 사진, 도 2는 2차 변색패턴 광학부(2mm)이다.Fig. 1 is a photograph of the first discoloration pattern optical part (5 mm) of the present invention, and Fig. 2 is a photograph of the second discoloration pattern optical part (2 mm).
도 3은 본발명의 변색 패턴별 렌즈이다.Figure 3 shows a lens according to the discoloration pattern of the present invention.
변색 안료의 양은 1, 2차 변색안료를 합쳐서 콘택트렌즈 제조원료의 1~ 2중량%정도이며, 그중 1차 변색 안료 양은 1차 안료 양의 30~70중량%, 2차 변색 안료 양은 2차 안료 양의 30~70중량%을 혼합한다. 그러므로 동공이 조절되는 듯하게, 서서히 동공 존 부분으로 변색된다.The amount of discoloration pigment is approximately 1 to 2 wt% of the contact lens manufacturing raw material by combining the primary and secondary discoloration pigments, and among them, the amount of the primary discoloration pigment is mixed at 30 to 70 wt% of the amount of the primary pigment, and the amount of the secondary discoloration pigment is mixed at 30 to 70 wt% of the amount of the secondary pigment. Therefore, as if the pupil is being adjusted, discoloration gradually occurs in the pupil zone area.
또한, 본발명은 자외부 광량에 따른 콘택트렌즈 패턴 변색에 대해서는 그라데이션 변색, 단일 변색, 독특한 디자인문양 발현 등에 적용시켜 다양한 렌즈의 패턴을 구성할 수 있다.In addition, the present invention can be applied to various lens patterns, such as gradient discoloration, single discoloration, and expression of unique design patterns, with respect to discoloration of contact lens patterns depending on the amount of ultraviolet light.
곧 본발명은 동공부 크기조절과 패턴변색이 모두 가능한 렌즈로서 1차 변색 안료, 2차 변색 안료를 적용한 렌즈로서 빛의 광량에 따라 눈을 보호할 수 있는 콘택트렌즈이다.The present invention is a contact lens that can both adjust the pupil size and change the pattern, and that applies a primary discoloration pigment and a secondary discoloration pigment, and that can protect the eyes according to the amount of light.
곧 빛의 광량에 따라 색이 변화하는 렌즈로서 기존 브라운 컬러 디자인 패턴 + 변색 안료 (Violet) 동공 조절 시안 패턴 적용 렌즈를 예를 들면,For example, a lens that changes color depending on the amount of light, such as a conventional brown color design pattern + a photochromic pigment (Violet) pupil-adjusting cyan pattern lens,
도 4는 본발명의 변색 전후 렌즈 디자인 색체 변화사진, 도 5는 본발명의 실리콘 함량에 따른 변색 전후 변화사진이다.Figure 4 shows photographs of color changes in the lens design before and after discoloration of the present invention, and Figure 5 shows photographs of changes before and after discoloration according to the silicone content of the present invention.
기존의 단순한 변색 렌즈가 아닌 디자인 및 패턴에 변색 안료를 도입시키기 위해 세부 렌즈 컬러 패턴 및 다양한 색상에서 이런 패턴들을 좀 더 선명하게 발현시키기 위해 변색안료와 적합한 렌즈이다.This is a lens suitable for photochromic pigments to introduce photochromic pigments into designs and patterns, rather than the simple photochromic lenses of the past, to express these patterns more clearly in detailed lens color patterns and various colors.
변색 안료는 렌즈의 구성성분의 종류에 따라 그 발현도가 차이가 있음을 확인했다.It was confirmed that the expression level of discoloration pigments differs depending on the type of lens component.
실리콘 종류 및 실리콘 함량에 따라 그 변색정도가 달랐고, 이는 렌즈 컬러 패턴 및 색상에 따라 그에 맞는 변색을 발현 시킬 수 있는 조성물을 개발한 것이다.The degree of discoloration varied depending on the type and content of silicone, and this led to the development of a composition that can exhibit discoloration appropriate to the lens color pattern and color.
