The Oakley Splice Goggle has an interchangeable lens design that features semi-flush lens mounting, a means of optimizing downward visibility. Side-to-side vision is also maximized. Oakley designers matched optical innovations in lens contouring with structural refinements, so even the strap outriggers are engineered to stay out of the way and help maintain a panoramic view with wide-open peripheral vision. The Oakley tech team went even further, devising a way to eliminate the keyhole structures that normally come with interchangeable lens designs. The process of lens changing has never been faster or more efficient. Oakley Splice Goggle lenses are dual vented and feature OakleyÆs F3 anti-fog technology.
