Production Introduction
1. Substrate absorption: the lens substrate is added with anti-blue light factor to absorb harmful blue light in life, so as to achieve the purpose of blue light blocking.
2, film reflection: lens surface coating, through the film will be harmful blue light reflection, blue light barrier protection purpose.
3, substrate absorption + film reflection: this technology integrates the advantages of the first two technologies, double-pronged, double-effect protection. [3]
According to the principle of complementary color, blue and yellow are complementary colors. Whether it is absorbed by the lens substrate or reflected by the film layer, part of the blue light is blocked, so the background color of the anti-blue light glasses will be yellow. The higher the barrier ratio, the deeper the background color of the lens will be. This is the basic physical principle of anti-blue light glasses.
