Abstract

PURPOSE: A method for coloring a glasses lens is provided to obtain the desired color of the glasses lens by varying the thickness of a coating layer formed on the surface of the glasses lens. CONSTITUTION: A hard coating process is carried out at the upper portion of a plastic based substrate(1) by using a silicon based water glass for forming a hard coating layer(2). Then, an SiO2, ZrO2, SiO2, ZrO2, and SiO2 layer(3,4,5,6,7) are sequentially coated at the upper portion of the hard coating layer. Then, a waterproof coating layer(8) is formed at the upper portion of the SiO2 layer(7) as an uppermost layer. At this time, the color of a glasses lens is varied by changing the thickness of at least one selected from a group consisting of the SiO2, ZrO2, SiO2, ZrO2, and SiO2 layer(3,4,5,6,7).

본 발명은 플라스틱 계열의 안경렌즈에서, 플라스틱 렌즈표면에 코팅되는 여러 겹의 코팅면 에 대한 두께를 조절하여 안경렌즈가 띄게 되는 색상을 조절해주도록 하는 안경렌즈의 착색방법에 관한 것이다.The present invention relates to a method of coloring a spectacle lens for controlling the color of the spectacle lens by adjusting the thickness of the coating layer of the multiple layers coated on the plastic lens surface in the plastic-based spectacle lens.

플라스틱 계열(무기유리, PMMA, PC, PS, CR-39, AS수지, PVC, PCHMA, MS수지, TPX 등)의 안경렌즈는 도 1 에 도시된 바와 같이 렌즈의 손상을 방지하고 빛의 투과율은 향상시키는 한편 반사율은 감소시키기 위하여 렌즈(10)를 이루고 CR-39로 통칭되는 플라스틱 계열의 기판(1)위에 실리콘 계열의 물유리로 하드(HARD) 코팅(2)하고, 그 위에 순차적으로 SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)를 다층 코팅시키며 최상층에 수막을 방지하는 발수코팅(8)을 하므로써 이루어진다.Spectacle lenses of plastic series (inorganic glass, PMMA, PC, PS, CR-39, AS resin, PVC, PCHMA, MS resin, TPX, etc.) prevent damage to the lens and transmittance of light as shown in FIG. In order to improve the reflectance while reducing the reflectivity, a hard (2) (HARD) coating of silicon-based water glass (2) is formed on the plastic substrate (1), which is referred to as CR-39, and then sequentially onto SiO 2 ( 3), ZrO 2 (4), Si0 2 (5), ZrO 2 (6), SiO 2 (7) is a multi-layer coating and the top layer is made by water repellent coating (8) to prevent water film.

이러한 플라스틱 계열의 안경렌즈에서 색상을 갖게 하기 위해서는 플라스틱의 원료에 색상을 나타내는 염료 또는 안료를 배합하여 색상을 갖도록 하거나, 렌즈의 코팅면에 금속박막을 얇게 코팅하여 특정의 색상을 갖도록 하고 있다.In order to have a color in such a plastic-based spectacle lens is to have a color by mixing a dye or pigment representing the color to the raw material of the plastic, or a thin metal coating on the coating surface of the lens to have a specific color.

본 발명은 플라스틱 계열의 안경렌즈에서 렌즈의 표면에 코팅되는 코팅면의 두께를 달리하여 원하는 색상을 갖도록 한 것으로, 플라스틱 렌즈의 색상을 내기 위하여 안료나 염료를 혼합하거나 코팅시 색상을 나타내기 위한 금속막을 날려주어야 하는 불편을 없애는 것이다.The present invention is to have a desired color by varying the thickness of the coating surface is coated on the surface of the lens in a plastic-based spectacle lens, a mixture of pigments or dyes to give a color of the plastic lens or a metal for showing the color when coating It is to eliminate the inconvenience of blowing up the curtain.

이러한 본 발명은 안경렌즈의 표면에 코팅되는 SiO2와 ZrO2의 코팅면 두께를 다르게 조절하여 두께가 다른 코팅면에서 반사되는 빛이 다르게 하므로써 원하는 색상을 갖는 안경렌즈를 제조할 수 있는 것이다.The present invention is to adjust the thickness of the coating surface of SiO 2 and ZrO 2 coated on the surface of the spectacle lens differently to produce a spectacle lens having a desired color by varying the light reflected from the different coating surface.

본 발명은 플라스틱 계열의 기판(1)위에 실리콘 계열의 물유리로 하드(HARD) 코팅(2)하고, 그 위에 순차적으로 SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)를 다층 코팅시키며 최상층에 수막을 방지하는 발수코팅(8)을 하게되는 안경렌즈(10)에 있어서, 상기 SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)로 이루어진 코팅면의두께를 달리하므로써 이루어진다.The present invention is a hard (HARD) coating (2) of silicon-based water glass on a plastic substrate (1), and sequentially thereon SiO 2 (3), ZrO 2 (4), Si0 2 (5), ZrO 2 (6), in the spectacle lens (10) having a multi-layer coating of SiO 2 (7) and a water repellent coating (8) to prevent water film on the top layer, the SiO 2 (3), ZrO 2 (4), Si0 2 (5) and ZrO 2 (6) and SiO 2 (7) by varying the thickness of the coating surface.

본 발명은 SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)중 어느 하나의 코팅면 두께를 달리하거나 두 가지 이상의 코팅면 두께를 달리할 수 있는 것으로, SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)의 코팅면 두께가 달라지게 되면, 상기된 코팅면에서 반사되는 빛의 양이나 세기가 달라지게 되고 이는 곧 안경렌즈의 색상을 의미하게 된다.The present invention may vary the coating surface thickness of any one of SiO 2 (3), ZrO 2 (4), Si0 2 (5), ZrO 2 (6), and SiO 2 (7), or It can be, if the coating surface thickness of SiO 2 (3), ZrO 2 (4), Si0 2 (5), ZrO 2 (6), SiO 2 (7) is changed, it is reflected from the coating surface described above The amount or intensity of light will change, which means the color of the spectacle lens.

즉 SiO2(3), ZrO2(4), Si02(5), ZrO2(6), SiO2(7)의 코팅면이 형성된 안경렌즈(10)로 빛이 전달되면 빛은 상기된 코팅면을 통과하는 한편 코팅면의 표면에서 반사하게 되며, 상기 반사된 빛이 실질적으로 안경렌즈(10)의 색상을 결정하게 되므로, 코팅면의 두께를 달리하면 반사되는 빛의 량이 달라지게 되어 결국 안경렌즈(10)의 색상을 나타내게 된다.That is, when light is transmitted to the spectacle lens 10 having the coating surfaces of SiO 2 (3), ZrO 2 (4), Si0 2 (5), ZrO 2 (6), and SiO 2 (7), the light is coated as described above. While passing through the surface and reflecting from the surface of the coating surface, since the reflected light substantially determines the color of the spectacle lens 10, by varying the thickness of the coating surface, the amount of reflected light is changed and eventually the glasses The color of the lens 10 is shown.

이같이 본 발명은 안경렌즈(10)의 코팅면 두께를 달리하면 코팅면의 두께에 따라 색상이 다르게 나타나므로 코팅면의 두께를 조절하여 원하는 색상의 안경렌즈(10)를 만들 수 있는 것이다.As described above, the present invention may change the thickness of the coating surface of the spectacle lens 10 so that the color appears differently according to the thickness of the coating surface, thereby controlling the thickness of the coating surface to make the spectacle lens 10 having a desired color.

본 발명은 플라스틱 안경렌즈의 코팅면 두께를 달리하여 원하는 색상을 갖도록 하는 것으로, 기존과 같이 안료나 염료를 혼합하는 과정이 불필요하고, 별도의 금속박막을 코팅하여야 하는 불편이 사라지게 되어 별도의 과정을 추가하지 않고도 간편하게 원하는 색상을 갖는 안경렌즈를 제조할 수 있는 것이다.The present invention is to have a desired color by varying the thickness of the coating surface of the plastic spectacle lens, the process of mixing pigments or dyes as in the prior art is unnecessary, and the inconvenience of having to coat a separate metal thin film is eliminated. It is possible to easily produce a spectacle lens having a desired color without adding.
