Built with sport performance in mind, Oakley gave Targetline Prizm an angled brow and sleek temples designed to fit well under a hat. The integrated side shields help combat backside glare, while the taller lens ensures uninterrupted downward vision. The flatter lens base provides a more lifestyle look and allows for a wider range of prescriptions. The textured inner temples and a no-slip Unobtainium nosepiece give a comfortable fit while maintaining retention. A Three-Point Fit optimizes comfort while keeping the lenses in precise optical alignment, ensuring the innovations of XYZ Optics can maximize clarity at all angles of vision.
