| description | The present invention relates to a blue light-blocking contact lens and a method of manufacturing the same. According to the present invention, the method comprises: a first step of coating a blue light-blocking dye on a silicone pad in a pupil shape; a second step of injecting a stirred lens raw material into a lower mold; a third step of pressing an upper mold and the lower mold, and injecting the pressed upper and lower molds into a thermal oven of 120°C to polymerize the stirred lens raw material for 60 to 90 minutes; and a fourth step of separating the upper and lower molds to obtain a contact lens, hydrating the contact lens with a physiological saline containing 0.9% of sodium chloride for 20 to 25 hours, and preserving the hydrated contact lens in a contact lens preservation solution. According to the present invention, the method can prevent eyesight deterioration by blocking a blue light wavelength range of 400 to 450 nm affecting retina, and can prevent a risk of damaging to the retina or crystalline lens by minimizing factors that may cause eye strain, headache, and macular degeneration. Further, the method has an effect of securing safety by pad-printing a front portion of the lens to a pupil size with the blue light-blocking dye, thereby preventing the front portion of the lens pad-printed with the blue light-blocking dye from being directly brought into contact with the eye. Further, the method has an effect of preventing the environment that may have an effect on a cycle of biological rhythms or hormone secretion by being excessively exposed to a light source having blue light generated therefrom at night.
본 발명은 블루라이트 차단 콘택트렌즈 및 제조방법에 관한 것으로, 실리콘패드에 블루라이트 차단 염료를 동공 모양으로 찍는 제 1단계와 하형몰드에 교반한 렌즈 원료를 넣는 제 2단계와 상형몰드와 하형몰드를 압착하여 120℃의 열 오븐에 넣고 60~90분 동안 중합하는 제 3단계와 상형몰드 및 하형몰드를 분리하여 콘택트렌즈를 취득한 후 염화나트륨 0.9% 생리식염수에 20~25시간 동안 수화 시킨 후 콘택트렌즈 보존액에 보관하는 제 4단계의 방법으로 구성되어, 망막에 영향을 미치는 400~450nm의 블루라이트 파장대를 차단하여 시력저하를 방지하고 눈의 피로감 및 두통, 황반변성을 유발할 수 있는 인자를 최소화시켜 망막이나 수정체에 손상을 가져오는 위험을 방지할 수 있다. 그리고 렌즈 앞부분에 블루라이트 차단 염료를 동공크기로 패드 프린팅하여 눈과 직접적으로 닿지 않게 하여 안정성을 확보하는 효과가 있다. 또한 야간에 블루라이트가 발생되는 광원에 과다하게 노출되어 생체리듬주기나 호르몬 분비에 영향을 줄 수 있는 환경을 방지할 수 있는 효과가 있다. |
