Oakley’s SI Tombstone™ is a revolutionary eyeshield that delivers exceptional optical performances for modern competitive shooters.

Oakley’s SI Tombstone Eyeshield is designed to address several of the most crucial issues competitive shooters encounter with conventional eyewear, including field of view, contrast and clarity, and lens interchangeability. The durable, stress-resistant O Matter™ frame is rimless, thus increasing the passive field of view to 120 degrees. The eyeshield incorporates Oakley SI Prizm™ technology, which strategically blocks wavelengths along the color spectrum in order to maximize contrast between colors and provide the user with enhanced vision when shooting. Prizm technology boosts the user’s visual recognition of targets while blocking various neighboring backgrounds such as dirt, trees, and sky; it also reduces the eye fatigue and strain on the user. The eyeshield features a rapid, single-release trigger lens exchange system that allows users to interchange lenses easily without touching and leaving fingerprints on them. Offering an extended range of view, enhanced color contrast, and an easy-to-use interchangeable lens system, Oakley’s SI Tombstone is an advanced shooting eyeshield that provides excellent performances for modern marksmen and markswomen.
