1. With blue cut materials in the monomer, our anti-blue lens can protect your eyes from harmful blue light.
2. By coating - Cut harmful blue light more effectively.
3、Combine blue cut materials in the monomer and Coating on a glass lens, most effectively block the harmful blue light.
4、Ensure transmittance, reduce chromic aberration. ( Blue light resistance is not the higher the better, the real good anti-blue glass lens should effectively block harmful blue light. )
5、Good blue light glasses block the blue light with the most harmful wavelength from 420nm-450nm while minimizing the color difference.
