Not only is carrying slew of different lenses a major hassle on the mountain, but it also increases the chance of scratching them when you're constantly swapping between tints. Achieving crystal clear vision in widely fluctuating alpine conditions, the Revo Rollo Women's Goggle features a Polarized Photochromatic Serilium Lens that rapidly adapts to stormy and sunny conditions alike. This lens also blocks harmful UV radiation and High Energy Visible Light when you're skiing or riding at high altitudes. Adapting to incoming light within 40 seconds, this photochromatic lens adjusts from 32% to 12% visible light transmission VLT when storm clouds depart and leave blinding sunshine to contend with. Its natural state of 32% VLT is great for overcast to socked in conditions while the activated 12% VLT tint accommodates the sunniest of alpine conditions. Additionally, this lens features a 50% polarization that cuts blinding glare without compromising your ability to read the terrain below you or view smartphone screens. Designed with a dual lens construction and Air Vent technology, the Rollo keeps built up condensation and fogging at bay when you're ripping high speed laps on warmer spring days or skiing through soaking wet conditions. The adjustable strap features anti slip silicone beads that ensure a secure, stay put fit. Furthermore, Revo provides triple layer face foam for an delightfully soft feel without irritation.
