All VonZipper goggles have a special lens coating. Only clean your goggle lens by using a cleaner specifically developed for lenses with a microfiber lens cleaning cloth or goggle bag. To avoid damage to the lens, DO NOT clean your goggles with t-shirts, paper towels or snow yetis. These can grind dust and fibers into lenses leaving scratches. Avoid using household detergents, soaps or glass cleaners, which are highly corrosive and can damage your lenses quickly. Sunscreen and other lotions can also damage the paint and coating on the lens and frame. When you are not wearing your goggles, keep them in their protective microfiber case or hard case. This will ensure that they will be in good shape the next time you are ready to shred the pow.
You must use care when changing the goggle lens. Make sure your hands are clean and dry when switching lenses. Do not change the lens while wearing gloves. This will scratch the lens.
All VonZipper snow lenses are pre-curved to fit the curve of the goggle frame. In order to maintain their shape, keep the lenses protected from flattening during travel, do not store the lenses flat and do not ride flat runs!
