Modo ECO is a collection of eyewear that brings environmental responsibility to eyewear. The line uses recycled stainless steel to create frames that fuse fashion and sustainability for the stylish and boasting a 360-degree approach to sustainability without sacrificing quality, design or price. Each new pair is accompanied by a mail-in recycling kit for old frames. Each frame is identified by a circle on the outer temple, subtly marking its authenticity. Modo plants a tree for each frame purchased.
