Sunglasses generally come in one of two materials: metal or plastic. iWood Ecodesigns has now thrown a third material into the sun-shading mix: sustainable wood. Like pricey hybrid cars and recycled designer denim, iWood sunglasses would certainly fit into the category of ecoluxury.Made from high-quality, sustainable wood veneer with quality components and Italian lenses, these unusual sunglasses have all the cache of a pair of pricey Prada shades without any of the sweat-shop labor or the easily knocked-off design.
