What is the blue light blocking principle of K-lon nano glasses?

K-lon nano glasses uses cutting-edge nano-optical coating technology. The microscopic particle structure in the coating can accurately identify and selectively block blue light in a specific wavelength range. Specifically, for the high-energy short-wave blue light frequency band of 400-450nm emitted by electronic device screens, the coating acts like a fine filter, effectively intercepting these blue lights that are extremely destructive to the retinal cells of the eyes, preventing them from penetrating the lenses and reaching the eyes. At the same time, for relatively beneficial blue light around 450-500nm, such as blue light components that help regulate the biological clock, it is allowed to pass through the lenses normally, so that the eyes can be protected from the invasion of harmful blue light while not lacking the beneficial stimulation of necessary blue light, protecting eye health in all aspects.
