Buyer's Tip: The Oakley Given Sun sunglasses style is manufactured with lightweight materials and precision engineering to provide sunglasses that not only provide quality optics but unsurpassed comfort. Premium quality OptiPad® replacement nose pads for the Oakley Given Sun compliment this fine frame in that only the softest most supple top-grade silicone is used in their fabrication. Each silicone nose pad is constructed with a soft outer shell that encloses an air bubble chamber that acts like a shock absorber. Each nose pad separates the weight of the sunglasses frame from the underlying nasal area where the frame makes contact with the wearer.
