How does the lifetime warranty on VIF glasses work? When can I claim my frames?
The lifetime warranty covers defects and fatigue in the material of the frames.
For a practical example, think of it like a car warranty. If a part goes off within the warranty period, the dealership will replace it with a new one free of charge, but if you crash your car or scrape it against a wall, of course, that's not quite reason for a warranty claim because it's the owner's fault and the manufacturer can't be held responsible. That's exactly how the VIF sunglasses warranty works.
