Lens Technology Lens Technology All our goggles feature high-clarity lenses available in loads of different shapes, finishes and colors. LENS SHAPES CYLINDRICAL LENSES Savor’s lenses curve horizontally while remaining flat vertically. They’re high quality polycarbonate double lenses with awesome clarity and a cool mirrored finish. Cylindrical lenses offer great performance at a slightly lower price. SPHERICAL-LENSES The spherical lenses on Revel and Revent Q curve horizontally and vertically around your face, giving the goggles a cool bubbled look. They also offer brilliant clarity and field of vision. UV PROTECTION UV rays are the most dangerous of the sun’s rays. Even on cloudy days you can be exposed to a lot of UV rays up the mountain, and it can cause all sorts of damage to your eyes. As a result all our lenses have UV filters to filter out 100% of UV rays – whether the lenses are tinted, dark or mirrored. LENS TINTS AND COLORS Color has no impact on the quality of a lens. However, the lens color does protect eyes from glare and can maximize visibility in flat light. How much depends on the percentage of visible light allowed through the lens (the Visible Light Transmission, or VLT). This is rated in categories from 0 to 4. All our lenses fall between 1 and 3: LENS CATEGORIES Cat 0: These lenses are a pale color or appear as a very light tint. They allow 81% to 100% of visible light through the lens. Cat 1: These are slightly tinted and allow 43% to 80% of visible light through the lens. Recommended for low light in winter or overcast days. Cat 2: These allow 18% to 42% of visible light through the lens. Effective protection in average sunlight conditions. Cat 3: These are perfect for most conditions and will provide excellent protection from the sun. They allow 8% to 17% of visible light through the lens. Cat 4: The most powerful category, allowing only about 3% of visible light through the lens. They are only necessary in extremely bright conditions, like when hiking on glaciers or in high mountains. LENS TECH All our lenses feature class 1 optics. It means they offer 100% UVA/B protection. They’re anti-scratch and anti-fog. They comply with standards EN1836, ANSI Z80.AS/NZS 1067 for high-impact resistance. And they also come in a range of finishes: PHOTOCHROMIC Our exclusive photochromic lenses respond to changing light conditions by adjusting the level of tint. When it’s dark they get lighter. When the sun comes out they get darker to protect you from glare. So you’ve always got the perfect lens tint for any condition – without having to change a thing. MULTILAYER (ML) A multilayered mirror finish increases protection from glare and reduces eye fatigue. The perfect balance between style and performance. prevents glare and makes skiing in bright light much more comfortable and safe.
