Oakley SI introduces a revolutionary competitive shooting eyeshield, Tombstone™. We worked with top marksmen to identify the most crucial problems they encountered with conventional eyewear. The response focused on three specific areas: Field of View, Contrast/Clarity, and Lens Interchangeability. Solving these problems was at the forefront of designing all aspects of Tombstone™. Using eye-tracking technology, we identified the key zones in your field of view to allow for 120 degrees of vision. We incorporated PRIZM™ technology to provide contrast enhanced viewing to help lock in your target and decrease eye fatigue/eye strain. Finally; we integrated a single release trigger for rapid lens exchange that is fingerprint free. The end result: Tombstone™ our most advanced shooting eyeshield delivering unprecedented performance for the modern day marksman.
