GLCO (Garrett Leight California Optical) embodies Californian cool, with eyewear designed and hand-finished in LA’s Arts District. In 2022, they launched their first eco-friendly collection using a biodegradable, bio-based acetate made from vegetable starch and bioethanol — reducing reliance on fossil fuels without compromising style or quality. GLCO sources premium materials from top suppliers in Italy, Japan, and China, and partners with a family-owned factory in China to ensure ethical, high-quality manufacturing at a fair price.
