High Definition Optics® (HDO®) is a collection of patented technologies that allow Oakley eyewear to meet or exceed the testing standards of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance.

All Oakley eyewear is warranted against breakage due to material or workmanship defect for two years from the date of purchase with a valid Proof of purchase. Oakley’s warranty program does not cover scratched lenses. Additionally, any alterations of Oakley products (i.e. sunglasses fit with non-Oakley prescription lenses) will void warranty coverage.

For all non-prescription and prescription warranty claims, please contact your original retailer or submit an online claim at http://www.luxottica.com/en/northamerica-after-sales-service
