The present invention relates to a blue light blocking contact lens and a manufacturing method, The first step of dipping the blue light blocking dye into the shape of the pupil on the silicon pad and the second step of putting the stirred lens material into the lower mold, and compressing the upper mold and the lower mold into a heat oven at 120 ° C. and polymerizing for 60 to 90 minutes. It is composed of the third step to obtain the contact lens by separating the upper mold and the lower mold, and then hydrated in 0.9% physiological saline for 20-25 hours, and then stored in the contact lens preservation solution, affecting the retina By blocking the 400 ~ 450nm wavelength of the blue light to prevent visual loss and minimize the factors that can cause eye fatigue, headache, macular degeneration can be prevented the risk of damage to the retina or lens. In addition, the blue light-blocking dye is printed on the front of the lens with a pupil size to prevent direct contact with the eyes, thereby securing stability. In addition, there is an effect that can prevent the environment that may affect the biorhythm cycle or hormone secretion by being excessively exposed to the light source generated blue light at night. |
