OO® Red Iridium® Polarized - No pain, no gain — but it’s not just muscle exhaustion that challenges road cycling and running. The blinding glare from flat surfaces can strain your eyes and fatigue you to the point where you’re ready to quit, or probably should because your mental focus is gone. That’s why we engineered the OO® Red Iridium® Polarized lens to cut 99% of glare from paths and pavement. Harsh rays of light won’t distract you, and with the improved depth perception of enhanced visual contrast, you’ll spot loose gravel and sand, small cracks, potholes and even slick areas that can be danger zones.
