Description Features Kids Blue AND Green Light Blocking Glasses Our scientifically-designed-and-manufactured kids blue and green light blocking glasses feature our custom-designed Noctural Red 550 Lens, these kids glasses have been specifically designed and proven to block 100% of blue and green light from 380-550nm.

Green light up to 550nm at night can also send daytime signals to the brain. For optimal night-time protection we need to remove 100% of blue AND green light up to 550nm.
