Ray-Ban’s RB4330CH delivers cutting-edge performance and style in a single frame. Using a unique polymer blend called PEEK to construct the frame, the result is remarkable flexibility, light weight and durability for a superior fit compared to other fashion frames. Chromance lenses use a mix of colour contrast and lens polarisation to deliver crystal clear, high-definition vision in a wide range of conditions. All of this technology is wrapped up in a trendy square shape with Ray-Ban branding on metal temple details.
