Oakley lens tints are designed to provide the best possible combination of light filtering, color balance, and visual contrast. In the mountains, visibility can vary unpredictably from blinding storms to bright sunlight and everything in between. Oakley offers a full range of technologies combined with base tints specially developed with exclusive IRIDIUM® coatings designed to optimize, enhance contrast, and balance light transmission. Important note: be especially careful when installing or removing replacement lenses. Scratched lenses will not be accepted and are not covered by the Oakley warranty.
