No matter how you see the world, these shades from Sunski will help upgrade your view. The Bernina Sunglasses are subtle yet unique with sturdy dual-material construction, stainless steel hinges, as well as palladium-coated and electroplated stainless steel frames. This ensures they're built to last and hold up to the everyday wear and tear you'll put them through. Even the polarized CR-39 lenses are made for the long haul, with superior clarity, abrasion resistance, and strength. Comfortable and timeless, the vintage-inspired shades are finished with perforated sun shields for side glare protection.
