INDOOR OUTDOOR BLUE

PROTECT AGAINST HARMFUL BLUE LIGHT

Overexposure to blue light, including smart phones, tablets and computer screens, has been known to cause eyestrain, fatigue and possibly contribute to long term macular degeneration. I/O Blue lenses are uniquely coated to help filter out harsh blue light and improve worker comfort and visual acuity. Lenses are also treated with a contrast booster to enhance color contrast.
