Most defects are in the frame with small abrasions or scratches. These abrasions give zero issue to the form and comfort when wearing them. Seize the chance to the already most affordable polarized glass lens at crazy low price. Be part of our history with our prototypes. An extra pair for driving, fishing, or yard work....plenty of good reasons for an extra pair of a great polarized glass lens sunglasses.
