Optimized peripheral vision with its frameless design, the Revo Wordsmith Goggle offers crystal clear optical clarity through a wide variety of alpine conditions. Not only is its frameless design eye catching, but more importantly, it boosts peripheral vision when you're negotiating crowded slopes and double diamond steeps. Loaded with a Polarized Photochromatic Lens, the Wordsmith Goggle rapidly changes its tint in as little as 40 seconds to accommodate rapid changes in lighting conditions. In fact, its photochromatic lens is able to darken from 32% to 12% visible light transmission VLT when storm clouds depart and leave blinding sunshine to contend with. The lens tint also changes in the opposite direction, lessening its tint to accommodate quick moving storm fronts and nasty oncoming blizzards. Moreover, this lens features 50% polarization to cut distracting glare, also blocking harmful UV and High Energy Visible Light from damaging your eyes, especially at high altitudes where incoming solar radiation is most intense. Designed with a dual lens construction and Air Vent technology, the Wordsmith keeps fogging and built up condensation at bay during warmer spring days and soaking wet storm cycles. The adjustable strap features anti slip silicone beads for an ultra secure fit. As if that's not enough, the plush triple layer face foam conforms to your face for a comfortable, ultra secure fit.
