All Miu Miu eyewear is warranted against breakage due to material or workmanship defect for two (2) years from the date of purchase with a valid Proof of purchase. Miu Miu’s warranty program does not cover scratched lenses. Additionally, any alterations of Miu Miu products (i.e. sunglasses fitted with non-Miu Miu prescription lenses) will void warranty coverage.
All warranty claims are subject to a case-by-case evaluation.
Please be advised that certain Miu Miu sunglasses feature a square-shaped brand etching on the left lens. This is an intentional design element that reflects the brand's identity and is not considered a defect or a warranty issue. As such, it will not be classified as "faulty."
