The present invention relates to a blue light blocking contact lens and a method for manufacturing the same, which can prevent deterioration and remove eye fatigue, headache and macular degeneration.
일반적으로 빛은 파장에 따라서 자외선, 가시광선, 적외선으로 나눌 수 있고 가시광선은 흔히 사람의 눈으로 볼 수 있는 빛으로 가시광선의 파장은 380~780nm의 영역에 해당된다. 이 중에서 400~490nm 사이에 존재하는 파란색 계열의 빛을 블루라이트인 청색광으로 구분한다. 근래에 생활환경 변화에 따라 전자기기의 사용이 증가 되면서 TV와 컴퓨터 등 스마트기기의 디스플레이와 LED조명기기에서 방출되는 블루라이트에 무방비로 노출되면서 이에 따른 인체 유해성에 대해 연구가 진행되고 있다. 일부 연구를 통해서는 블루라이트에 오래 노출되면 눈의 피로를 가중시키고 안구 건조증을 유발하며 심한 경우 눈 속의 망막이나 수정체에 손상을 가져오는 유해성도 주장되고 있으며 또한 야간에 블루라이트가 발생되는 광원에 계속 노출되면 생체리듬주기 변화나 호르몬 분비 변화에도 영향을 줄 수 있다는 의견이 있다.In general, light can be classified into ultraviolet light, visible light, and infrared light according to the wavelength. Visible light is commonly seen by the human eye, and the wavelength of visible light is in the range of 380 to 780 nm. Among these, the blue light existing between 400 and 490 nm is classified into blue light, which is a blue light. In recent years, as the use of electronic devices has increased due to changes in living environment, research on the harmful effects of human beings is being conducted as it is exposed to blue light emitted from displays and LED lighting devices of smart devices such as TVs and computers. Some studies have also suggested that long exposure to blue light can increase eye fatigue, cause dry eye, and, in severe cases, damage the retina or lens in the eye, and continue to be affected by light sources that produce blue light at night. There is an opinion that exposure can also affect changes in biorhythm cycle or hormone secretion.

도 2은 본 발명에 따른 블루라이트 차단 콘택트렌즈 및 제조방법에 있어서, 콘택트렌즈 크기 및 블루라이트 차단 기능 부분 크기를 나타내는 도면으로서, 이를 참고하여 본원발명의 상세 구성을 설명하면 아래와 같다. 2 is a view illustrating a contact lens size and a size of a blue light blocking function in a blue light blocking contact lens and a manufacturing method according to the present invention.
콘택트렌즈 동공 부분에만 블루라이트 차단 기능이 제공되는 특징으로 콘택트렌즈 크기는 14.0~14.5mm이고, 블루라이트 차단을 위해 콘택트렌즈 앞부분에 블루라이트 차단 염료를 패드 프린팅 시 해당 범위는 사람의 동공 크기에 맞도록 차단 기능 부분 크기를 2~10mm로 정한다. 이는 평균 사람의 동공 크기가 2~6mm이지만 환한 공간에서 갑자기 어두운 공간으로 갔을 때 시각적으로 적응하기 위한 암순응의 과정을 거칠 시 동공이 10mm까지 커지기 때문이다.The blue light blocking function is provided only in the contact lens pupil area, and the contact lens size is 14.0 ~ 14.5mm, and the range of the blue light blocking dye is printed on the front of the contact lens to block the blue light. Set the blocking function part size to 2 ~ 10mm.
