Oakley Crosslink is the epitome of versatility. Oakley Crosslink Switch takes versatility to another level. Oakley Crosslink Switch prescription glasses allow you to "switch" lenses so you can go from Rx eyeglasses to Rx sunglasses with one Oakley frame. Oakley Crosslink Switch is sophisticated enough for the office, yet tough enough for high-performance action. With true sport components like impact-resistant frame & lenses and anti-slip Unobtainium nose pads & temple grips, the Oakley Crosslink Switch can take you from all business to all play, day or night. Plus, each pair of Crosslink Switch eyeglasses comes with two different colors of interchangeable temples.
