Oakley Chrystl Ahyris Collection sunglasses owe their smooth aesthetic to the single design mechanism that combines the frames and temples. Lightweight yet sturdy O Matter teams up with pressure-resistant stainless steel to create these durable and comfortable shades. The double bridge that connects the lenses serves as reinforcement to the rimless frames and also adds visual impact. The patented Three-Point Fit keeps these frames in optical alignment for vision that's crystal clear. Open endpoints and a signature O at the temple add designer appeal to these Chrystl sunglasses from Oakley.
