The RX series is one of the most pioneering approaches to wood frame prescription sunglasses. We are excited to offer those who need prescription lenses the opportunity to share the joy of wearing a pair of wooden frames! The unique design is split on the sides which allows the frame to separate and open up the lens cavity. This makes it easy to insert a prescription lens provided by your optometrist. This custom one of a kind wood frame is exclusive to SwitchWood and only made possible with the flexibility and strength of our T800 series carbon fiber core.
