Each frame is fitted with CR39 lenses that have built-in blue light blocking filters in addition to a blue AR coating on both surfaces.
The combination of these filters work together to absorb and deflect 100% of the blue light under 410nm and 32% of the blue light on the 410nm - 500nm spectrum.
G1 blue light blockers are designed to support your eyes by reducing the effects of blue light emitted from digital screens and natural sunlight, which can contribute to eye strain, fatigue and disrupted sleeping patterns.
