To the untrained eye, the Viper may look like ordinary protective sunglasses, but underneath the frames are the wind-blocking characteristics of a goggle. A patented Orbital Seal (soft foam padding around the frames) seal your eyes, creating a protected environment. Our peepers felt safe and didn't get dry, although the wind did seep through at higher speeds (above 40 mph). We opted for the Rider Lens (Blue Flash), which showed us the road with razor-sharp definition and clarity. The lenses are also anti-fogging and shatter-resistant, so we didn't run into any unexpected visual impairment during unusual weather conditions. Peripheral vision was excellent.
