Description

블루 계열의 식별 색상을 갖는 콘택트렌즈 및 이의 제조방법{A Contact Lens Having A Blue-based Identification Color and Manufacturing Method Thereof}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a contact lens having a blue-based identification color,

본 발명은 블루 계열의 식별 색상을 갖는 콘택트렌즈 및 이의 제조방법에 관한 것으로 보다 상세하게는 투명 콘택트렌즈 제조 시 콘택트렌즈 폴리머 내의 특정한 성분으로 인하여 나타나는 노란색을 가리기 위하여 식별 컬러를 첨가하는 것으로 두 가지 안료를 사용하여 안정성과 투명도가 확보되는 블루 계열의 식별 색상을 갖는 콘택트렌즈 및 이의 제조방법에 관한 것이다.The present invention relates to a contact lens having a blue identification color and a method of manufacturing the same. More particularly, the present invention relates to a contact lens, which comprises an identification color added to cover a yellow color due to a specific component in a contact lens polymer, To a contact lens having an identification color of blue system in which stability and transparency are secured, and a method of manufacturing the same.

콘택트렌즈는 결점이 있는 시력을 교정하기 위하여 각막 위에 올려놓는 시각 보조 기구로서 눈의 치료에 도움을 주며 시력 교정 목적 이외에도 직업적, 미용적 등의 다양한 목적으로 사용된다. Contact lenses are a visual aids that are placed on the cornea to correct defective visual acuity. They are used for a variety of purposes such as professional and cosmetic purposes as well as vision correction purposes.

콘택트렌즈를 착용하는 연령은 점차 낮아지는 추세이며, 안경 착용에 대한 불편함 및 미용에 대한 관심이 높아짐에 따라 중, 고등학생은 물론 초등학교 고학년 때 부터 콘택트렌즈를 착용하기 시작하고 있다. The age at which contact lenses are worn down is gradually decreasing. As a result of the inconvenience of wearing glasses and increasing interest in cosmetics, middle and high school students are beginning to wear contact lenses from the upper grade of elementary school.

이렇게 시력이 좋지 않은 착용자들이 콘택트렌즈를 분실하지 않고 식별할 수 있도록 블루 또는 그린 계열의 색상을 첨가하여 콘택트렌즈를 제조한다. 또한, 투명 콘택트렌즈를 제조 시 식별 색상을 첨가하지 않으면 콘택트렌즈 폴리머 내의 성분으로 인하여 노란 색상이 나타나게 되는데 렌즈가 두꺼운 경우 노란 색상이 더 진하게 나타나기 때문에 식별 색상을 첨가하기도 한다.These contact lenses are manufactured by adding blue or green-based colors to wearers with poor vision so that they can identify the contact lens without losing it. In addition, when a transparent contact lens is manufactured, a yellow color appears due to the components in the contact lens polymer unless the identification hue is added. When the lens is thick, the yellow color appears darker, so identification color is added.

대한민국 등록특허공보 제10-0614779호에서는 식별 마크를 갖는 콘택트렌즈를 개시하고 있으나 이는 식별 색상이 아닌 마크가 육안으로 식별됨에 따라 사용자는 타인의 식별 마크 인지에 대한 부담감을 느끼는 문제점이 발생한다. Korean Patent Publication No. 10-0614779 discloses a contact lens having an identification mark. However, since a mark, which is not an identification color, is visually recognized, the user feels a sense of burden for the identification mark of the other person.

또한, 콘택트렌즈 제조 업체마다 비슷한 식별 색상의 콘택트렌즈를 제공함에 따라 두 가지 이상의 콘택트렌즈를 착용하는 사용자는 사용 기간이 다른 두 가지 이상의 콘택트렌즈 간의 식별에 어려움을 느끼는 문제점이 발생한다.Further, since contact lens manufacturers provide similar contact lenses with similar identification colors, users wearing two or more contact lenses have difficulty in identifying between two or more contact lenses having different periods of use.

블루 계열의 식별 색상을 갖는 콘택트렌즈의 제조 방법에 있어서 HEMA(2-Hydroxyethyl Methacrylate) 99~99.9중량%와 안료 0.1~1중량%를 혼합하여 안료 혼합물(A)을 제조하는 제1단계(S10)와 HEMA(2-Hydroxyethyl Methacrylate) 65~75중량%와 NVP(N-Vinyl-2-Pyrrolidone) 2~4중량%와 GMMA(Glycerol MonoMethacrylate) 22~28중량%와 EDMA(3,4-Ethylenedioxy-N-Methylamphetamine) 0.3~0.7중량%와 HA(hyaluronic acid) 0.1~0.4중량%와 UV차단제 0.5~1.5중량%와 제1단계(S10)가 완료된 안료 혼합물(A) 0.1~0.4중량%를 혼합하여 30분 동안 200rpm으로 교반한 후에 콘택트렌즈 몰드에 주입 후 상, 하 몰드를 조립하는 제2단계(S20)와 조립된 몰드를 120℃의 열 오븐에 넣고 60~90분 동안 중합한 뒤 상, 하 몰드를 분리하여 콘택트렌즈를 취득하는 제3단계(S30)와 0.9% 염화나트륨으로 이루어진 생리식염수에 20~25시간 동안 수화시킨 후 콘택트렌즈 보존액에 보관하는 제4단계(S40)로 구성되는 것을 특징으로 한다.A method for manufacturing a contact lens having a blue-based identification color comprises the steps of: (a) preparing a pigment mixture (A) by mixing 99 to 99.9% by weight of HEMA (2-hydroxyethyl methacrylate) with 0.1 to 1% And 65 to 75% by weight of HEMA (2-Hydroxyethyl Methacrylate), 2 to 4% by weight of NVP (N-vinyl-2-pyrrolidone) and 22 to 28% by weight of GMMA (Glycerol MonoMethacrylate) 0.3 to 0.7% by weight of hyaluronic acid, 0.1 to 0.4% by weight of HA, 0.5 to 1.5% by weight of a UV screening agent and 0.1 to 0.4% by weight of a pigment mixture (A) (S20) in which the upper and lower molds are injected into a contact lens mold after stirring at 200 rpm for a minute, and the assembled mold is placed in a heat oven at 120 DEG C and polymerized for 60 to 90 minutes. Then, A third step (S30) of acquiring a contact lens, and a physiological saline solution containing 0.9% sodium chloride for 20 to 25 hours, It characterized by comprising a first step by column 4 (S40) to.

안료 혼합물(A)은 HEMA(2-Hydroxyethyl Methacrylate) 99중량%에 안료 1중량%를 첨가한 후 160~190rpm으로 70~75시간 동안 교반 후 사용하며, 색차계를 이용하여 색상 확인을 할 수 있다.The pigment mixture (A) is prepared by adding 1 wt% of pigment to 99 wt% of HEMA (2-Hydroxyethyl Methacrylate), stirring the mixture at 160 to 190 rpm for 70 to 75 hours, and color-checking using a colorimeter .

상기의 안료 혼합물(A)은 콘택트렌즈 제조 전에 HEMA에 안료를 첨가하여 혼합함으로 안료의 균일도를 높이는 효과가 있다.The above-mentioned pigment mixture (A) has the effect of increasing the uniformity of the pigment by adding the pigment to the HEMA before mixing the contact lens.

또한, 상기의 안료 혼합물(A)에 사용되는 안료는 1,4-BIS(4-(2-METHACRYLOXYETHYL)PHENYLAMINO)ANTHRAQUINONE 30~40중량%와 1,4-Bis[(2-methacryloxyethyl)amino]-9,10-anthraquinone 60~70중량%로 이루어진 것을 특징으로 하며, 각각 안료의 함량에 따라 녹색 빛 또는 블루 빛에 가까운 색상을 제작할 수 있다. The pigment used in the pigment mixture (A) is a pigment comprising 30 to 40% by weight of 1,4-BIS (4- (2-METHACRYLOXYETHYL) PHENYLAMINO) ANTHRAQUINONE and 1,4-Bis [(2-methacryloxyethyl) amino] And 60 to 70% by weight of 9,10-anthraquinone, respectively. Depending on the content of the pigment, a color close to green light or blue light can be produced.

1,4-BIS(4-(2-METHACRYLOXYETHYL)PHENYLAMINO)ANTHRAQUINONE의 함량이 높을수록 블루 계열의 색상이 나타나고, 1,4-Bis[(2-methacryloxyethyl)amino]-9,10-anthraquinone의 함량이 높을수록 녹색 계열의 색상이 나타나며, 1,4-BIS(4-(2-METHACRYLOXYETHYL)PHENYLAMINO)ANTHRAQUINONE이 48중량% 이상으로 넘어가면 콘택트렌즈는 녹색 계열의 색상을 띄게 되고, 이보다 함량이 줄어들수록 블루 계열의 색상을 진하게 띄게 된다. 상기와 같이 제조된 안료를 HEMA와 혼합하여 사용하며, 시야 확보에 불편함이 없는 정도의 투명도를 갖도록 한다.1,4-Bis (4- (2-methacryloxyethyl) amino] -9,10-anthraquinone was found to be present in the blue color as the content of ANTHRAQUINONE increased. When the amount of 1,4-BIS (4- (2-METHACRYLOXYETHYL) PHENYLAMINO) ANTHRAQUINONE is more than 48% by weight, the color of the contact lens becomes greenish. As the content decreases, The colors of the series are emphasized. The pigment prepared as described above is mixed with HEMA and used so as to have transparency to such an extent that it is not inconvenient for securing visibility.

본원발명은 상기와 같이 두 가지 안료를 사용하여 새로운 색감의 식별 색상을 갖도록 하며 회사 고유의 색상을 제공하여 사용자가 타 렌즈와의 식별을 용이하도록 돕는 효과가 있다. 즉, 사용기간 또는 사용 목적이 다른 두 렌즈를 사용할 때 색상으로 구분이 가능하도록 한다.The present invention has the effect of enabling the user to easily distinguish from other lenses by providing the unique color of the new color using the two pigments as described above and providing the unique color of the company. In other words, it is possible to distinguish the color when using two lenses having different usage periods or purposes.

본 발명은 특정의 실시 예 및 적용 예와 관련하여 도시 및 설명하였지만, 첨부된 특허청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화 가능하다는 것을 당 업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described with respect to specific embodiments and applications thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
