Abstract: front page image
(EN)According to the present invention, in connection with manufacturing of a soft contact lens for presbyopia, a light-transmitting area is formed at the center portion of the soft contact lens at a predetermined diameter so as to transmit light such that, by selectively blocking light coming into the eye, the focal depth can be increased. In addition, a light-blocking area is formed along the outer periphery of the light-transmitting area at a predetermined diameter, and micro-holes are formed in the light-blocking area such that the density of distribution of the micro-holes increases towards the outer periphery of the corresponding area, thereby securing the amount of light, which may otherwise be insufficient due to setup of the light-blocking area, and securing a bright field of view. Furthermore, in relation to a presbyopia improvement pattern comprising the light-transmitting area and the light-blocking area, the position of formation on the area of the soft contact lens is adjusted in conformity with the corneal topographical map of each soft contact lens user such that, even in the case of a user having a different corneal topographical map, the soft contact lens can be used normally. In addition, the light-transmitting area and the light-blocking area are subjected to coloring using colors that can adjust the contrast sensitivity such that not only the contrast sensitivity can be adjusted, but UV rays or blue light can also be blocked, thereby preventing optic nerves or visual cells from being damaged.
(FR)L'invention porte sur la fabrication d'une lentille de contact souple pour la presbytie. Selon la présente invention, une zone de transmission de lumière est formée au niveau de la partie centrale de la lentille de contact souple à un diamètre prédéterminé, de façon à transmettre la lumière de telle sorte que, par blocage sélectif de lumière entrant dans l’œil, la profondeur focale peut être augmentée. En outre, une zone de blocage de lumière est formée le long de la périphérie externe de la zone de transmission de lumière à un diamètre prédéterminé, et des micro-trous sont formés dans la zone de blocage de lumière de telle sorte que la densité de la distribution des micro-trous augmente vers la périphérie externe de la zone correspondante, ce qui permet de garantir la quantité de lumière, qui peut sinon être insuffisante en raison de la mise en place de la zone de blocage de lumière, et garantir un champ de vision clair. En outre, par rapport à un motif d'amélioration de la presbytie comprenant la zone de transmission de lumière et la zone de blocage de lumière, la position de la formation sur la surface de la lentille de contact souple est réglée en conformité avec la carte topographique de la cornée de chaque utilisateur de lentille de contact souple, de telle sorte que, même dans le cas d'un utilisateur ayant une carte topographique de cornée différente, la lentille de contact souple peut être utilisée normalement. En outre, la zone de transmission de lumière et la zone de blocage de lumière sont soumise à une coloration à l'aide de couleurs qui peuvent régler la sensibilité de contraste, de telle sorte que non seulement la sensibilité de contraste peut être réglée, mais des rayons UV ou une lumière bleue peuvent également être bloqués, ce qui permet d'empêcher que des nerfs optiques ou des cellules visuelles soient endommagés.
(KO)본 발명에 따르면, 노안을 위한 소프트 콘택트 렌즈의 제조에 있어서, 소프트 콘택트 렌즈의 중심부에 일정 크기의 지름을 가지는 빛을 투과시키는 광투과영역을 형성하여 눈으로 들어오는 빛을 선택적으로 차단시킴으로써 초점심도를 높일 수 있다. 또한, 광투과영역의 외곽으로는 일정 지름을 가지는 광차단영역을 형성하고 광차단영역에는 미세구멍을 형성하되 해당 영역의 외곽쪽으로 갈수록 미세 구멍의 분포 밀도가 증가하도록 구성함으로써 광차단영역의 설정으로 인해 부족할 수 있는 빛의 양을 확보하여 밝은 시야를 확보할 수 있다. 또한, 광투과영역과 광차단영역으로 구성되는 노안 개선 패턴에 대해서는 소프트 콘택트렌즈 사용 대상자별 각막지형도에 맞게 소프트 콘택트 렌즈의 영역상 형성 위치가 조정되도록 함으로써 서로 다른 각막지형도를 가지는 사용 대상자의 경우에도 소프트 콘택트 렌즈가 정상적으로 사용될 수 있도록 한다. 또한, 광투과영역과 광차단영역에 대조감도를 조절할 수 있는 색으로 착색을 수행하여 대조감도를 조절할 뿐만 아니라, 자외선이나 청색광을 차단시켜 시신경이나 시세포의 손상을 막을 수 있다.
