Description

In particular, an inclined surface having a predetermined angle is formed on a convex mold having a precise lens contact surface to precisely form the curvature of the concave surface of the contact lens, and then the contact lens is formed on a contact surface of the concave mold. The present invention relates to a method of manufacturing a contact lens for producing a large amount of precise and precise contact lenses because the convex surface is formed by polymerizing the convex surface and then fixing the convex mold to the shelf jig to process the convex surface of the contact lens.
일반적으로 우리들의 신체에서 눈이 차지하는 비중은 거의 절대적이라 해도 지나친 말은 아닌 듯하다. 사람이 앞을 볼 수 없는 상태로 모든 일을 스스로 할 수는 없을 것이다. 그러므로 각자 자신의 시력보호를 위해 애쓰는 것은 의무에 가깝다고 하겠으며 이미 굴절이상이 있는 경우의 시력교정은 콘택트렌즈와 안경일 것이다.In general, the proportion of snow in our bodies is almost absolute, but it doesn't seem like an overkill. Man will not be able to do everything himself without seeing. Therefore, each of us will try to protect our own eyesight is a duty, and in the case of refractive errors already, the corrected vision will be contact lenses and glasses.
콘택트렌즈는 안구 즉, 각막표면에 직접 접촉된 상태에서 빛을 원하는 형태로 굴절시켜 시력교정을 하는 것으로 각막상의 눈물층과 결합하고 있으며, 안경과는 달리 얼굴에 고정되지 않고 안구에 고정되어 있기 때문에 안경으로서는 해결할 수 없는 광학적인 장점이 있다. 즉, 각막 표면의 요철로 인해 생기는 부정난시의 교정, 온도와 습도 차에 의한 환경조건의 변화에도 착용중인 렌즈가 흐려지지 않고, 프리즘작용이 없으며, 시야가 넓고, 상의 배율차도 훨씬 적다는 장점이 있다.The contact lens refracts the light into the desired shape in direct contact with the eye, ie, the cornea surface, and corrects the vision. It is combined with the tear layer on the cornea. There is an optical advantage that cannot be solved. In other words, the lens is not blurred, there is no prism, the field of view is wider, and the magnification difference of the image is much smaller even though correction of irregular astigmatism caused by irregularities on the surface of the cornea and changes in environmental conditions due to temperature and humidity difference. have.
상기한 콘택트렌즈는 제조하기 위한 일반적인 방법은 주조법과 선반절삭법이 사용되어지고 있으며, 주조법은 고정주조법과 회전주조법으로 나뉘어진다.As a general method for manufacturing the contact lens, a casting method and a lathe cutting method are used, and the casting method is divided into a fixed casting method and a rotation casting method.
고정주조법은 볼록금형과 오목금형 사이에 단량체를 넣고서 자외선을 주사하여서 콘택트렌즈를 만드는 방법으로서, 다량의 렌즈를 동일한 재현성을 유지하면서 만들 수 있다는 장점을 지닌다. 하지만 실제로는 동일한 품질의 렌즈를 생산하기 위하여서는 엄격하게 제어되어야 할 것이 많고 곡률과 도수, 두께 및 바란스에 따른 수 많은 금형이 필요하므로 이 금형을 만들기 위한 매우 정교한 암,수금형을 만들기가 매우 어렵고, 렌즈의 디자인 변화가 심한 현실에 비추어서 눈의 조건을 맞추어서 디자인을 잡아야 하므로 금형을 수시로 바꾸기 어려운 문제점을 지닌다.The fixed casting method is a method of making a contact lens by inserting a monomer between a convex mold and a concave mold to scan ultraviolet rays, and has the advantage of making a large number of lenses while maintaining the same reproducibility. In reality, however, it is very difficult to produce very sophisticated female and mold molds for producing these lenses because there are many things that need to be strictly controlled in order to produce lenses of the same quality and many molds are required according to curvature, frequency, thickness and balance. In the light of the severe design change of the lens, it is difficult to change the mold from time to time because it is necessary to catch the design according to eye conditions.
회전주조법은 오목금형에 단량체(Monomer)를 주입하여서 회전에 의한 원심력과 자외선으로 광중합을 시키는 콘택트렌즈 제조방법으로서, 이 방법에 의하여 제조된 콘택트렌즈는 매끄러운 표면을 가지며 대량생산도 가능하여 단가를 저렴하게 할 수 있지만 도수에 따라서 콘택트렌즈 오목면의 곡률이 다르므로 고도근시렌즈 의 제작이 어렵고 광학부, 베벨, 중심두께, 직경의 차이 등의 변화가 동반될 수 있다.The rotation casting method is a method of manufacturing a contact lens in which a monomer is injected into a concave mold and photopolymerized by centrifugal force and ultraviolet rays by rotation. The contact lens manufactured by this method has a smooth surface and can be mass-produced to reduce the unit cost. However, because the curvature of the contact lens concave surface varies according to the frequency, it is difficult to manufacture the high myopia lens, and the optical part, the bevel, the center thickness, and the difference in diameter may be accompanied.
또한 제조기술 상에서 결함이 발생될 수 있다. 예를 들어서 여러 가지 제조인자 즉, 회전속도와 단량체 주입량 및 중합속도 등의 영향이 많고 렌즈의 가장자리의 처리를 둥굴게 처리하는 데 어려움이 있다.Defects can also occur in manufacturing techniques. For example, there are many factors such as rotational speed, monomer injection amount and polymerization rate, and it is difficult to round the edges of the lens.
선반절삭법은 콘택트렌즈의 오목면과 볼록면을 선반으로 절삭하고 표면의 미세한 요철면을 연마기로 연마하여 제조하는 방법이다. 이 방법은 제작자가 손쉽게 양면에 다양한 곡면을 줄 수 있어서 소비자의 요건에 따라 항상 변화가 가능하지만 렌즈의 직경이나 오목면의 곡률을 항상 일정하게 유지하기가 어려우며 대량생산이 어려운 문제점이 있었다.The lathe cutting method is a method of manufacturing the concave and convex surfaces of a contact lens by cutting them with a lathe and polishing the fine concavo-convex surface of the surface with a polishing machine. This method is easy for the manufacturer to give a variety of curved surfaces on both sides can always be changed according to the requirements of the consumer, but it is difficult to always maintain the constant curvature of the diameter or the concave surface of the lens, there was a problem that mass production is difficult.
본 발명은 이러한 점을 감안하여 안출한 것으로서, 정밀한 렌즈접촉면을 갖는 볼록금형에 일정각도의 경사면을 형성하여 콘택트렌즈의 오목면의 곡률을 정교하게 형성한 후 오목금형의 렌즈볼록부 접촉면에 콘택트렌즈의 볼록면을 중합시켜 형성한 후 선반지그에 볼록금형을 고정시켜 콘택트렌즈의 볼록면을 절삭하여 가공하므로 정밀하고 정교한 콘택트렌즈를 대량으로 생산하는 것이 목적이다.The present invention has been made in view of the above-described problems, and an inclined surface having a predetermined angle is formed on a convex mold having a precise lens contact surface to precisely form the curvature of the concave surface of the contact lens, and then a contact lens on the convex lens convex contact surface. After the convex surface is formed by polymerizing, the convex mold is fixed to the shelf jig to be processed by cutting the convex surface of the contact lens. Therefore, the purpose is to produce a large amount of precise and precise contact lenses.
