When new parts are purchased through our repair department, the two-year warranty will renew on those parts. If your repairs are covered under warranty or completed at no charge, the warranty coverage would continue from the original purchase date of your Maui Jim polarized sunglasses. That being said, we are always happy to evaluate your Maui Jim polarized sunglasses and your situation to see what we can do to help. You can access a repair form, and shipping instructions by visiting our Repair Page.
