● Compared with the anti-blue light lens directly coated with anti-blue light film (the blue film will make the reflection of the lens obvious and affect the visual effect to a certain extent), adding anti-blue light raw materials to the lens base can maximize the transmittance of light;
● Compared with the anti-blue light lens with a background color, the color sense when viewing objects is weakened, and the blue block lens guarantees the light transmission while ensuring anti-blue light effect, and restores the true color of the object itself;
● By adding an anti-blue light factor to the lens base material, the absorption of high-energy blue light is realized, and the good and bad blue light that directly enters the fundus is effectively distinguished, and the harmful high-energy short-wave blue light is reflected or absorbed while the beneficial long wave blue light is allowed to pass;
● The addition of a super waterproof film layer makes the lens have good wear-resistant, anti-fouling, anti-UV, anti-radiation, high-definition and light-transmitting effects.
