The Clear Rare Blanc Duke by James Oro is a pair of men’s rectangular rimless glasses with clear lenses and temples carved from buffalo horn, with 18K gold PVD plated hardware. It’s made for collectors who want to elevate their look, and the clear lenses keep the focus on the horn and the gold. It’s also a strong gift for someone who collects frames. Custom laser-engraved nosepads add comfort. The clear nylon lenses have UV400 and 100% UVA/UVB protection. With a 146mm front, it sits best on medium to wide faces. Measurements: 56mm lens width, 21mm bridge, 140mm temples, 146mm front frame.
