Trash or beans—take your pick. Depending on the color, the frames of Revo’s Backbay sunglasses are produced from either leftover plastic scraps (black) or the castor oil from the fast-growing and environmentally castor bean (brown), though you wouldn’t know it from their sleek cyborg styling. Like all of the company’s shades, the lenses are polarized to reduce glare and heighten contrast, especially on water.
