What this means
Clear “blue light” lenses block almost nothing. The Day Lens is tinted for a reason: independent testing shows it blocks 89% of blue light while keeping colors natural, so your eyes stay relaxed through long days at the screen.
It also blocks 100% of UV-A and UV-B and passes EN ISO 12312-1, the international standard for lens transmittance and safety. Real protection has a color.
