Blue Light Blocking Lens
The wavelength of blue light is between 380nm and 500nm. The range part of ultraviolet near the visible light has high energy will transmit from transparent medium to our eyes retina directly. Among them, the short blue light rays with its wavelength of 380-450nm is the most harmful to eyes retina. Crystal star anti blue light lens scientifically balances the blue light wave and blocks the most harmful range of 380nm-450nm radiation rays and keeps the beneficial wave band of 450-500nm, which not only has anti blue light effect but also maintains good light transmittance.
1. Nanometer anti blue light coating with HD light transmittance
2. Blocks harmful blue rays to keep beneficial blue light
